Does anybody know this one? 40= 15 - 9x- 2
asambeis [7]

Step-by-step explanation:

Simplifying 40 = 15 + -9x + -2

Reorder the terms: 40 = 15 + -2 + -9x

Combine like terms: 15 + -2 = 13 40 = 13 + -9x

Solving 40 = 13 + -9x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '9x' to each side of the equation. 40 + 9x = 13 + -9x + 9x

Combine like terms: -9x + 9x = 0 40 + 9x = 13 + 0 40 + 9x = 13

Add '-40' to each side of the equation. 40 + -40 + 9x = 13 + -40

Combine like terms: 40 + -40 = 0 0 + 9x = 13 + -40 9x = 13 + -40

Combine like terms: 13 + -40 = -27 9x = -27

Divide each side by '9'. x = -3

Simplifying x = -3

Lara found the volume of a sphere with a diameter of 10.
Paraphin [41]

Answer:

No, she used the diameter instead of the radius measure.

Step-by-step explanation:

we know that

The volume of the sphere is equal to

V=\frac{4}{3}\pi r^{3}

we have

r=10/2=5\ units ----> the radius is half the diameter

substitute

V=\frac{4}{3}\pi (5)^{3}

V=\frac{500}{3}\pi\ units^{3}

Becky has 9 bags of coins. Some of the bags contain 8 gold coins, and the rest contain 6
fredd [130]

Answer:

4 bags of gold coins and 6 bags of gold coins

Step-by-step explanation:

So, Becky has 9 bags of coins

This is basically a "trial and error" equation.

Now, she has 4 bags of 8 gold coins

8×4= 32

So she has 32 gold coins

Now, she has 5 bags of 6 silver coins

5×6=30

So she has 30 silver coins.

So we add these,

30+32= 62

HOPE THIS HELPS!!!
