Answer:

7+4

Step-by-step explanation:

When you are subtracting a negative, you are really adding the number. For example, four minus negative seven is equal to four plus seven.

4 - (-7) = 4+7

4+7 = 7+4 (By the commutive property of addition)

Jenny & Natasha are working on a problem together: Solve x/3 + 8 = −2. Natasha thinks the first step is to multiply by 3. Je

ratelena [41]

The individual that is correct is Natasha. This is because the answer can be gotten using Natasha's method

The given equation is $\frac{x}{3} + 8 = -2$

Solving the equation using Natasha's method

the fist step is to multiply by 2

x + 24 = - 6

The second step is to combine and add similar terms

x = -24 - 6

x = -30

Second method of solving the equation

The equation the friends are trying to solve is $\frac{x}{3} + 8 = -2$

The first step is to combine similar terms

$\frac{x}{3}$ = - 8 - 2

The second step is to add similar terms together

$\frac{x}{3}$ = - 10

The third step is to multiply both sides of the equation by 3

x = (-10 x 3)

x = -30

Find the scale factor of the similar shapes below.

timofeeve [1]

Answer:

x=12 and the scale factor is 1.5

Step-by-step explanation:

From D' to F' is 7.5 and from D to F is 5cm the difference is 2.5. From F' to E' is x and from F to E is 8. This is just understanding what you can see. You find x by figuring out the ratio from 5 to 7.5 is and 8 to x or vise versa. It depends which way you are going. I think you are going from E,D,F to E',D',F'. So from 5cm to 7.5 cm. This is 1.5 because you are dividing 7.5/5. If you needed to find x, it would be 12.

Solve for g. −3+5+6g=11−3g

Nataly_w [17]

Answer:

g = 1

Step-by-step explanation:

-3 + 5 + 6g = 11 - 3g

2 + 6g = 11 - 3g

Add 3g to both sides.

2 + 9g = 11

Subtract 2 from both sides

9g = 9

g = 1
