Answer:
39/10
39 ÷ 10= 3.9

See examples before for the method to solving literal equations for a given variable: Solve A = bh for b. Since h is multiplied times b, you must divide both sides by h in order to isolate b. Since (c+d) is divided by 2, you must first multiply both sides of the equation by 2.
Answer:
56°
Step-by-step explanation:
Because the two lines are parallel, the corresponding angles are equal. The two corresponding ∠s are ∠A and ∠B. ∠A=∠B
∠A=4x
∠B=2(x+14)
4x = 2 (x+14)
the right side requires the distributive property
a) 4x = 2x+28
2x = 28
x = 14
b) now plug in x for both ∠s to find ∠A and ∠B
∠A = 4x = 4(14) = 56°
∠B = 2(x+14) = 2(14+14) = 2(28) = 56°
I just did both angles to show that they are equal and it is a way to check your work

Answer:
A. Q = 15 °C
B. 0.4 °C
C. Q = 23 °C
Step-by-step explanation:
The following equation models the temperature of Quin's home,
Q = 15 + 0.4t
Where Q is the temperature in degree Celsius and t is the time in minutes
A. What was the temperature when Quinn returned from vacation?
At this time, t = 0 since Quin is just arrived
Q = 15 + 0.4(0)
Q = 15 °C
B. how much does the temperature increase every minute?
0.4(t)
0.4(1)
0.4 °C
The temperature increases by 0.4 centigrade every minute.
C. How much will the temperature increase if Quinn leaves the heat on for 20 minutes
For t = 20 mins
Q = 15 + 0.4(20)
Q = 15 + 8
Q = 23 °C
