<span>Simplifying 0.5s + 1 = 7 + 4.5s Reorder the terms: 1 + 0.5s = 7 + 4.5s Solving 1 + 0.5s = 7 + 4.5s Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-4.5s' to each side of the equation. 1 + 0.5s + -4.5s = 7 + 4.5s + -4.5s Combine like terms: 0.5s + -4.5s = -4s 1 + -4s = 7 + 4.5s + -4.5s Combine like terms: 4.5s + -4.5s = 0.0 1 + -4s = 7 + 0.0 1 + -4s = 7 Add '-1' to each side of the equation. 1 + -1 + -4s = 7 + -1 Combine like terms: 1 + -1 = 0 0 + -4s = 7 + -1 -4s = 7 + -1 Combine like terms: 7 + -1 = 6 -4s = 6 Divide each side by '-4'. s = -1.5 Simplifying s = -1.5

0.5s + 1 = 7 + 4.5s   Subtract 4.5s from both sides
  -4s + 1 = 7              Subtract 1 from both sides
       -4s = 6              Divide both sides by -4
          s = -\frac{6}{4}   Simplify
          s = -\frac{3}{2}

Anastasia uses the equation p = 0.7(rh + b) to estimate the amount of take-home pay, p, for h hours worked at a rate of r dollar
uranmaximum [27]

Complete question :

Anastasia uses the equation p = 0.7(rh + b) to estimate the amount of take-home pay, p, for h hours worked at a rate of r dollars per hour and any bonus received, b. What is an equivalent equation solved for h? A. h = (h equals StartFraction p Over 0.7 EndFraction minus b divided by r.– b)÷ r b. h = h equals StartFraction p Over 0.7 EndFraction minus b divided by r.– b ÷ r c. h = h equals left-parenthesis StartFraction p Over 0.7 EndFraction right-parenthesis divided by r minus b.÷ r – b d. h = h equals StartFraction p minus b Over 0.7 EndFraction divided by r. ÷ r

Answer:

[(p/0.7) - b] / r

A. h = (h equals StartFraction p Over 0.7 EndFraction minus b divided by r.– b)÷ r b. h = h equals StartFraction p Over 0.7 EndFraction minus b divided by r.

Step-by-step explanation:

Given the equation :

p = 0.7(rh + b)

Make h the subject

Divide both sides by 0.7

p / 0.7 = 0.7(rh + b) / 0.7

p/ 0.7 = rh + b

Subtract b from both sides :

(p/0.7) - b = rh + b - b

(p/0.7) - b = rh

Divide both sides by r

[(p/0.7) - b] / r = rh/ r

[(p/0.7) - b] / r = h

Find the surface area of the composite figure.
zhuklara [117]

Answer:

438.97 cm²

Step-by-step explanation:

To find the surface area, we break up the figure into two pieces(blue and yellow) and then add them together.

SA = 2(w · l + h · l + h · w)

2 · (6 · 16 + 4 · 16 + 4 · 6)

368 cm²

70.97 cm² + 368 cm²

438.97 cm²
