Manuel earns 5350 a month. if he worked eight hours a day for 20 days, how much did he make each hour? Express your answer in dollars and cents. (Rounded)
Answer:
$33.44Step-by-step explanation:
Working hours:
20 days, 8 hours a day20*8 = 160 hoursEarning in a month = $5350
Hourly earning rate:
5350/160 = 33.4375 = $33.44 roundedChange -3x+3y=9 into slope intercept form
To convert to slope-intercept form, we need to get the y by itself.
First add 3x to both sides to get 3y = 3x + 9.
I put the x term first because in slope-intercept form or y = mx + b form,
the x term will always come before the constant term.
Now divide both sides by 3 to get y = x + 3.
Answer:
y = x + 3
Step-by-step explanation:
-3x + 3y = 9
3y = 9 - 3x
/3 /3 /3
y = x + 3
Help me pleaseee I don’t understand
I'll solve one from each kind
Q1)
6 = a/4 + 2 (mutiply both sides)
24 = a + 8 (move the terms)
-a = 8 - 24 (calculate)
-a = 8 - 16 (change the signs)
a = 16
Q8)
2( 2 + 5) = -2 (divide both sides)
n + 5 = -1 (move the constant to the right)
n = -1 - 5 (calculate)
n= -6
Q3)
9x - 7 = 7 (cancel equal terms)
9x = 0 (divide both sides)
x = 0

Step-by-step explanation:
What should happen to both sides of the equation to isolate the variable?
Answer:
If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable
Step-by-step explanation:

How do you write 3.8 in scientific notation?
Answer:
3.8 × 10^{1}
Step-by-step explanation:
Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10b.
Follow the steps below to see how 38 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 38
New Number: 3.8
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 3 . 8
Decimal Count: 1
There are 1 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 3.8
b = 1
Now the whole thing:
3.8 x 10^{1}
Step 4
Check work:
10^{1} = 10 x 3.8 = 38

Which expression is equivalent to 1.8(2x + 7) - 15?
a 1.2x
b 3.6x - 2.4
0 3.6x - 8
d 16.2x - 15
Answer:
Option B. 1.8(2x + 7) – 15 = 3.6x – 2.4
Step-by-step explanation:
1.8(2x + 7) – 15
To know which option is correct, let us simplify the above expression. This can be obtained as follow:
1.8(2x + 7) – 15
Clear bracket
1.8(2x + 7) – 15 = 3.6x + 12.6 – 15
1.8(2x + 7) – 15 = 3.6x – 2.4
Thus,
1.8(2x + 7) – 15 is equivalent to
3.6x – 2.4

Draw the line segment AC and BD are the segments the same? Explain
Draw the rays CA and CB. Are the rays the same? Explain
Answer:
No they are not the same because.....
Step-by-step explanation:
Use the distributive property to simplify the expression below:
4x + 2(x+1)
A. 6x + 1
B. 6x + 2
C. 8x + 2x + 2
D. 4x + 2x + 2
Answer:
B)
Step-by-step explanation:
You would first multiply the variable and constant with the number next to the parenthesis. So you now have 4x+2x+2. Then you add up like terms to get a final answer of 6x+2.
i need < 2 and <4 help plz
Answer:
Step-by-step explanation:
m<3 = 43 degrees
add 43 degrees and 43 degrees and the answer is 86. and since everything equals 180 degrees, 180 - 86 = 94. since there are 2 side needed to be solved divide 94/2 = 47
so 47 degrees for <2 and 47 degrees for <4
to check my work just add up all the sides
47 degrees for <2, 47 degrees for <4, 43 degrees for <1, 43 degrees for <3
47 + 47+ 43+ 43= 180 degrees
hope this helps:)

Step-by-step explanation:
The m∠B is two more than three times the measure of ∠C. If ∠B and ∠C are complementary angles, find the measures of both angles.
Answer:
m∠B= 67
m∠C= 23
Step-by-step explanation:
okay so same thing we did before except they will equal 90 not 180
B= 3(c)+2
c+b=90
c+3(c)+2=90
4c+2=90
4c=92
c=23
now input them! or subtract!
90-23=67
m∠C=23
m∠B=67

2x/x-5 = 4 (solve this equation)
If possible, do please tell me on how to do these kind of questions! <3
Answer:
x=10
Step-by-step explanation:
(2x)/(x-5)=4
first you multiply the denominator on both sides
2x=4(x-5)
then multiply
2x=4x-20
then move all the x variables to one side and the constants to the other with subtraction and addition
20=2x
divide and you get x=10
you can plug this in to check your work and you'll see: (2(10))/(10-5)=4 or 20/5=4 which you know is true
Diego bought some raisins and walnuts to make trail mix. Raisins cost $4 a
pound and walnuts cost $8 a pound. Diego spent $30 on both ingredients.
Write an equation to represent this constraint. Let x be pounds of raisins
and y be pounds of walnuts.
Answer:
4x + 8y = 30
Step-by-step explanation:
Cost of raisins = $4 per pounds
Cost of walnuts = $8 per pounds
Total spent on both ingredients = $30
Let
Pounds of raisins = x
Pounds of walnuts = y
Diego's equation can be represented by
PxQx + PyQy = 30
Where,
Px = price of raisins
Qx = Quantity of raisins (pounds)
Py = price of walnuts
Qy = Quantity of walnuts (pounds)
PxQx + PyQy = 30
4x + 8y = 30
