Explanation:
The given equation is in the form
a + (b+c) = (a+b) + c
where,
a = -2.2b = -3.7c = -1.4The associative property of addition is what specifically is being applied. There's a multiplication version of this property as well. The associative property is the idea where we can move parenthesis around to group terms in different ways, and still get the same result regardless of what we did with the parenthesis.
------------
The associative property only works with addition and multiplication. Something like subtraction will be a different story
Eg: 1-(2-3) is different from (1-2)-3, so a-(b-c) is not the same as (a-b)-c

The measure of ∠2 is twelve less than five times the measure of ∠1. If ∠1 and ∠2 form a linear pair, find m∠2.
Given:
The measure of ∠2 is twelve less than five times the measure of ∠1.
∠1 and ∠2 form a linear pair.
To find:
The measure of ∠2.
Solution:
Let measure of ∠1 be x.
The measure of ∠2 is twelve less than five times the measure of ∠1.
[tex]m\angle 2=(5(m\angle 1)-12)^\circ[/tex]
[tex]m\angle 2=(5x-12)^\circ[/tex]
∠1 and ∠2 form a linear pair. So,
[tex]m\angle 1+m\angle 2=180^\circ[/tex]
[tex]x^\circ+(5x-12)^\circ=180^\circ[/tex]
[tex]6x-12=180[/tex]
[tex]6x=180+12[/tex]
[tex]6x=192[/tex]
Divide both sides by 6.
[tex]x=32[/tex]
Now,
[tex]m\angle 2=(5(32)-12)^\circ[/tex]
[tex]m\angle 2=(160-12)^\circ[/tex]
[tex]m\angle 2=148^\circ[/tex]
Therefore, the measure of angle 2 is 148 degrees.
Answer:
148 is the final answer

11. Which equation represents 4x - 3y = 15 when solved for y?
The equivalent value of the expression is y = ( 4x - 15 ) / 3
Given data ,
Let the equation be represented as A
Now , the value of A is
4x - 3y = 15
On simplifying the equation , we get
4x - 3y = 15
So , the left hand side of the equation is equated to the right hand side by the value of ( 15 )
Adding 3y on both sides , we get
3y + 15 = 4x
Subtracting 15 on both sides , we get
3y = 4x - 15
Divide by 3 on both sides , we get
y = ( 4x - 15 ) / 3
Therefore , the value of y = ( 4x - 15 ) / 3
Hence , the expression is y = ( 4x - 15 ) / 3

5 =2/3(8x-6)
Answer:
Step-by-step explanation:
5 = 2/3 ( 8x - 6 )
to make it clearer, we can just interchange the position of LHS and RHS
2/3 ( 8x - 6 ) = 5
By transposing,
8x - 6 = 5 - 2/3
8x - 6 = 13/3
8x = 13/3 + 6
8x = 31 / 3
x = 31 / 3 × 1/8
x = 31 / 24

1. Josh is traveling from South Carolina to California for summer vacation. The states se
Carolina to Texas is represented by 12x
- 106. The distance from Texas to California is
approximately 2500 miles apart, so he makes a pitstop in Texas. The distance from south
represented by (5x + 685).
5x + 685
12x = 106
Is Josh's pitstop in Texas the midpoint between South Carolina and California? Justify your
answer.
Answer:
Josh's parent's house in Texas is the midpoint between South Carolina and California.
Step-by-step explanation
Let distance from South Carolina to California = D
D = 2,500 miles
Let distance from South Carolina to Josh's parent's house in Texas = D1
D1 = 12x - 106
Let distance from Josh's parent's house in Texas to California = D2
D2 = 5x + 685
Solve if Josh's parent's house in Texas is the midpoint between South Carolina and California
D1 = D2 = D/2
D/2 = 2,500 miles / 2
= 1,250 miles
D1 = D2 = 1,250 miles
D1 + D2 = D
Substituting D1 = 12x-106 and
D2 = 5x+685 and
D = 2,500
D1 + D2 = D
(12x-106) + (5x+685) = 2,500
Open parenthesis
12x - 106 + 5x + 685 = 2,500
Collecting like terms
12x + 5x = 2,500 - 685 + 106
17x = 1,921
Divide both sides by 17
x = 1,921 / 17
= 113
x = 113
Substitute x into D1 and D2
D1 = 12x - 106
D1 =12(113) - 106
= 1,356 - 106
D1 = 1,250
D2 = 5x + 685
D2 = 5(113) + 685
= 565 + 685
D2 = 1,250
Therefore, Josh's parent's house in Texas is the midpoint between South Carolina and California
A person standing on a moving walkway travels 80 feet in 40 seconds. What equation represents the relationship? How many feet will a person travel in 10 seconds?
Answer:
Option B. y = 2x; 20 feet
Step-by-step explanation:
1. Determination of the equation that represents the relationship.
Let y be the distance travelled.
Let x be the time taken.
Let K be the speed.
From the question given above, the following data were obtained:
Distance (y) = 80 ft
Time (x) = 40 s
Speed (k) =.?
Speed = Distance /time
K = y/x ......... (1)
K = 80/40
K = 2 ft/s
Substitute the value of k into equation 1
K = y/x
K = 2 ft/s
2 = y/x
Cross multiply
y = 2x
Therefore, the equation that represents the relationship is y = 2x
2. Determination of the distance travelled in 10 s.
Speed (k) = 2 ft/s
Time (x) = 10 s
Distance (y) =.?
y = 2x
y = 2 × 10
y = 20 ft
Therefore, the person will travel 20 feet in 10 seconds.
From the above calculations, the right answer to the question is
Option B. y = 2x; 20 feet

Answer:
angle FXG is congruent to angle IXJ or JXI. GHI is 81°
Step-by-step explanation:
Angle FXG is congruent to angle IXJ because the two are vertical angles. (Vertical angle theorem)
FXG + GXH = FXH
Substitute the given values given:
49 ° + GXH = 130°
Subtract 49 both sides
49 - 49 + GXH = 130 - 49
GXH = 81°
Four subtract M over nine equal eleven
Answer:
-95
Step-by-step explanation:
(4 - m) / 9 = 11
Multiply both sides by 9:
4 - m = 99
Subtract both sides by 4:
-m = 95
Multiply both sides by -1:
m = -95
Answer:
-63
Step-by-step explanation:
4 - M = 11
---
9
Bring the 4 to the opposite side of the variable ( bring the 4 to the other side of the = sign where it shows 11 or a different number with no variable. basically if you get a question problem for math like this, and when you see a variable aka a letter, move it to the other side where it doesn't have a letter, move it with the = sign then add or subtract. if the number that your moving away from the variable is positive, you subtract making it negative... but if you have a negative number, do adding instead. )
4 - 11 = -7
subtract and then you muliply
M
--- = -7
9
once you mulipled -7 x 9
your answer should be
M = -63

Convert 5 days into years. Round your answer to the nearest hundredth.
Answer:
5/365 years, or 0.014 years
Step-by-step explanation:
Just like any conversion of units, we just set up the starting amount and multiply it by the correct ratio:
5 days (1 year/ 365 days) = 5/365 years = 0.014 years
You just need to make sure you choose the right ratio. In this case, I know that 1 year is 365 days, and I'm trying to cancel the days unit, therefore I put the year in the numerator and the days in the denominator.
I hope this helps :D
Answer:
0.01
Step-by-step explanation: 5 ÷ 365 ( days of year) and it gives you 0.013 then round to nearest hundredth and since 3 is less than 5 it becomes a 0

(6)(−6n)+(6)(−6)+−7=−331(Distribute)
−36n+−36+−7=−331

−36n+−43=−331
−36n−43=−331
Step 2: Add 43 to both sides.
−36n−43+43=−331+43
−36n=−288
Step 3: Divide both sides by -36.
−36n−36=−288−36

Cassandra rents a bicycle while on vacation.
The table below shows the cost of renting a bicycle y, per hour, x.
The value of the function when x = 0 is the y-intercept (b) of the function.
Find the y-intercept and explain in 2-3 sentences what it represents in this problem. For a bonus point, write the equation of this function in y = mx + b form by substituting the correct values for m and b.
Answer:
y = 6x + 14Step-by-step explanation:
As per given table we can see that
The value of y is 20, 26, 32, 38The rate of change = slope is 6With same rate of change y- intercept is 20 - 6 = 14The equation of the function is
y = mx + bAs m = 6 and b= 14, the function is:
y = 6x + 14I need help with this one.
Answer:
y=(-4/1)x-5
Step-by-step explanation:
You need to find the slope of the line and the y intercept, you can do this by plotting the points into a graph and figuring it out that way, or you can use the equations y2-y1/x2-x1 (for slope) and y=(*the slope from the other equation*)x+b. For both equations plug in a corresponding x and y coordinate given on the list (y1 and y2 would be consecutive coordinates, so 1 and 2, and same for x1 and x1, so -9 and -13). You should get (-4/1) for the slope, and when you plug that into the other equation you should get 5. Lastly you plug all these numbers into y=mx+b, and you get your answer.
Hope this helps :)
