I'm not sure if this is simply a true/false question but if so the answer is true. With a standard deviation of 1.8, your tests would always remain in the A range.

Hope that helps.

3x +15 = 2x + 10 + x + 5

Shkiper50 [21]

Answer:

The equation is true.

Step-by-step explanation:

Simplify. Combine like terms:

3x + 15 = (2x + x) + (10 + 5)

3x + 15 = (3x) + 15

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 3x and 15 from both sides:

3x (-3x) + 15 (-15) = 3x (-3x) + 15 (-15)

3x - 3x = 15 - 15

0 = 0

~ True. The two expressions are equal to each other.

80g + 30h = 10(g + h)

vladimir2022 [97]

Assignment: $\bold{Simplify \ Expression: \ 80g+30h=10\left(g+h\right)}$

<><><><><><><>

Answer: $\boxed{\bold{g=-\frac{2h}{7}}}$

<><><><><><><>

Explanation: $\downarrow\downarrow\downarrow$

<><><><><><><>

[ Step One ] Expand $\bold{10\left(g+h\right): \ 10g+10h}$

$\bold{80g+30h=10g+10h}$

[ Step Two ] Subtract 30h From Both Sides

$\bold{80g+30h-30h=10g+10h-30h}$

[ Step Three ] Simplify

$\bold{80g=10g-20h}$

[ Step Four ] Subtract 10g From Both Sides

$\bold{80g-10g=10g-20h-10g}$

[ Step Five ] Simplify

$\bold{70g=-20h}$

[ Step Six ] Divide Both Sides By 70

$\bold{\frac{70g}{70}=\frac{-20h}{70}}$

[ Step Seven ] Simplify

$\bold{g=-\frac{2h}{7}}$
