#1. 5(t+3)=-10
5t+15=-10
5t=-25
t=-5

#2. -(c-10)=0
-c+10=0
c=10

#3. -10(s+3)=-15
-10s-30=-15
-10s=15
s=-3/2

#4. 5(f-5)=-60
5f-25=-60
5f=-35
f=-7

#5. -5(2t+2)=-70
-10t-10=-70
-10t=-60
t=6

#6. 4(3w+2)/3=-6
12w+8=-18
12w=-26
w=-13/6

#7.Substitute the °C with -8
Equation:
5/9(F-32)=-8
divide both sides by 5/9
F-32= -14.4
add 32 to both sides
F=17.6
Answer: -8°C in °F is approximately 18°F.

BTW, to get the degree sign, it's option+shift+8.

2.5/6 = h/9 h=? What does this mean

omeli [17]

Answer:

h = 3.75

Step-by-step explanation:

Step 1: Write equation

2.5/6 = h/9

Step 2: Solve for <em>h</em>

Cross multiply: 22.5 = 6h
Divide both sides by 6: 3.75 = h
Rewrite: h = 3.75

Step 3: Check

<em>Plug in h to verify it's a solution.</em>

2.5/6 = 3.75/9
