Scientists are studying the temperature on a distant planet. They find that the surface temperature at one location is 40° Celsi

Answer:

T(h) = 20 - 3h

Step-by-step explanation:

We are told that for every km you go up, the temp goes down 3°.

Let's say you go up 1km, then the temp should be 17°. We can easily represent it by the equation: T(h) = 20 - 3h

If we go up 1km: T(1) = 20 - 3*(1) = 20 - 3 = 17°

If we go up 2km: T(2) = 20 - 3*(2) = 20 - 6 = 14°

If we go up 3km: T(3) = 20 - 3*(3) = 20 - 9 = 11°

Three fourths of x increased by 5 is - 7

Finger [1]

Answer:

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

Step-by-step explanation:

$\frac{3}{4} x+5=7$

Subtract 5 from both sides.

$\frac{3}{4}x+5-5=7-5$

Simplify.

$\frac{3}{4}x=2$

Multiply both sides by 4.

$4*\frac{3}{4} x=2*4$

Simplify.

$3x=8$

Divide both sides by 3.

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

Simplify.

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