Solve 7(y + 2) – (4y – 10) = 44 – 2y + 5
A.y = -5
B.y = 5
C.y = -10

Answers

Answer:

y = 5

Step-by-step explanation:

7(y + 2) – (4y – 10) = 44 – 2y + 5

(7y+14) - (4y - 10) = 49 -2y

3y +24 = 49 -2y

5y +24 = 49

5y = 25

y = 5

Answer:

y=5

Step-by-step explanation:

7(y+2)-(4y-10) = 44-2y+5 distribute on the left and combine like terms on the right side of the equation

7y + 14 -4y +10 = 49 - 2y move every term with a variable on the left side with a change sign and the numbers on the right side

7y-4y+2y =49 -14 -10

5y = 25 divide both sides by 5

y5/5=25/5 so

y=5

Answers

Answer:

Slope-intercept is y=-x/3

The slope is -1/3

The y-intercept is 0

Step-by-step explanation:

First, we need to put this as slope-intercept for which is y=mx+b

3y=-x

y=-x/3

hope this helps!

Answer:

The slope-intercept form is      y= -(1/3)x  

The slope is - (1/3)  

The y − intercept is 0

Step-by-step explanation:

x+3y=0

Substract x on both sides

3y= - x

Divide by 3 on both sides

y= - (x/3)x

y= -(1/3)x

In order to find the answer to this question you must change the mixed number into a improper fraction, use KCF, (Keep, Change, Flip) and solve.

[tex]2\frac{2}{3} \div\frac{4}{5}[/tex]

Convert into improper fraction:

[tex]2\frac{2}{3} =3\times2=6+2=8=\frac{8}{3}[/tex]

[tex]\frac{8}{3} \div\frac{4}{5}[/tex]

In a class of 42 students, 18 students are in the Math Club, 5 students
are in both the Math Club and the Science Club, and 14 are in neither. How many
students are in the Science Club?

Answers

Answer:

15 maybe?

Step-by-step explanation:

42 - 14 = 28

18 - 5 = 13

28 - 13 = 15

subtract the 14 because it says it is in neither.

Subtract 5 from 18 because 18 are in math and only 5 are in both math and science.

Subtract 13 from the 28 because those 13 are in math and wont be in science also.

2c + 5 + (15+10) 3 = 120

step by step please !!

Answers

Ok so I’m not sure but this is how we solve it in the way I learned.
-You add and simplify the equation first so it will be
2c + 20(3) = 120
2c + 60 = 120
-Then you subtract the 60 by itself and then the 120 and it leaves you with
2c = 60
-lastly you divide
2c/2 = 60/2
Then you find your answer is 30
C = 30

Answer:

solve for c

c = 20

Step-by-step explanation:

2c + 5 + 25 x 3 = 120

2c + 5 + 75 = 120

2c + 80 = 120

2c = 120 - 80

2c = 40

c = 20
