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
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:)
Change -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
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.
Does 1/6, -3, V7, -6/5 or 4.5 come first when the numbers are listed from least to greatest? Explain.
Answer:
-3
Step-by-step explanation:
Given numbers:
1/6, -3, √7, -6/5, 4.5
The smallest one is chosen between the two negatives as all the rest are greater.
- 3 is smaller than - 6/5= -1.2 as 3 > 1.2So the answer is -3
Greetings from Brasil...
Let's look at each number
1/6 = 1 ÷ 6 = 0.16666....
- 3 = - 3
√7:
√4 < √7 < √9, so
2 < √7 < 3 the result of √7 is between 2 and 3
-6/5 = (- 6) ÷ 5 or 6 ÷ (- 5) = - 1.2
4.5 = 4.5
Writing the numbers in ascending order can tell:
- 3; - 6/5; 1/6; √7 and 4.5or (same values - approximated values):
- 3; - 1.2; 0.2; 2.5 and 4.5

what is the expression: the quantity n minus 6 cubed? (in algebraic expression)
Answer:
The equation is either n-6^3 (this is without cubing the 6, this is probably what your teacher is looking for.) or n-216 (this is what the equation looks like when 6 is cubed)

Which is the slope of the line y = -3x +2?
Answer:
slope = - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 2 ← is in slope- intercept form
with slope m = - 3
Answer:
-3.
Step-by-step explanation:
in the form y=mx+b, m is the slope

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

PLEASE HELP- The time it takes for an object to follow certain distance can be calculated using the equation t=√2d/g where d represents distance and g represents the force of gravity on the object write the eqtion as a function of the distance and use 9.81 meters per second squared as the force of gravity calculate the distance the object will fall in 3 seconds label your answer.
Answer:
d= 44.145 m (meters)
Step-by-step explanation:
distance = (g*t²)/2
t=3 sec. d=? , g=9.81 m/s²
distance (d)=9.81*(3)²/2
d= 44.145 m

Show steps of how to factor (3x^2 + 5xy - 2y^2)
(3x² + 5xy - 2y²)
3x² + 5xy - 2y² (rewrite the expression) (write 5xy as a difference)
3x² + 6xy - xy - 2y² (factor the expression) (factor out 2x from the expression)
3x x (x + 2y) -y x (x + 2y) (factor the expression) (factor out x + 2y from the expression)
Solution : (x + 2y) x (3x - y)

six students out of 40 students In a class are absent what percentage of the students are absent
15%
Step-by-step explanation:
Absent= 6
Total student = 40
[tex] \frac{6}{40} \times 100 \\ \\ \frac{600}{40} = 15\%[/tex]
Step-by-step explanation:
Hey there!!
We can simply do it.
Here,
Total students =40
Absent students = 6
Now,
[tex]absent\% = \frac{no.asent}{total \: student} \times 100\%[/tex]
Keep all values.
[tex]absent\% = \frac{6}{40} \times 100\%[/tex]
= 15%
Therefore, the absent percentage is 15%.
