Answer 1

Answer:

#1 s=-133/5

#3 a. b=-4

#3 b. x=23.45

#3 c. p=201

Step-by-step explanation:

#1 −5(s+30)=−17

Step 1: Simplify both sides of the equation.

−5(s+30)=−17

(−5)(s)+(−5)(30)=−17(Distribute)

−5s+-150=−17

−5s−150=−17

Step 2: Add 150 to both sides.

−5s−150+150=−17+150

−5s=133

Step 3: Divide both sides by -5.

−5s−5=133/−5

s=−133/5

#3 a. $-\frac{1}{2} (b-6)=5$

Step 1: Multiply both sides by 2

$(-\frac{1}{2} (b-6))(-2)=5(-2)$

Step 2: Simplify

b-6=-10

Step 3: Add 6 to both sides

b-6+6=-10+6

Step 4: Simplify

b=-4

#3 b. 0.4t(x-0.45t)=9.2

Step 1: Divide both sides by 0.4

$\frac{0.4t(x-0.45t)}{0.4} =\frac{9.2}{0.4}$

Step 2: Simplify

x-0.45=23

Step 3: Add 0.45 to both sides

x-0.45+0.45=23+0.45

Step 4: Simplify

x=23.45

#3 -4(p-212)=44

Step 1: Divide both sides by -4

$\frac{-4\left(p-212\right)}{-4}= \frac{44}{-4}$

Step 2: Simplify (there is way more to this step than I am putting)

p-212=-11

Step 3: Add 212 to both sides

p-212+212=-11+212

Step 3: Simplify

p=201
