z = 106
y = 74
Since angle 74 and angle y are the same sizes, you can know for a fact they are the same measurments. Next, you would do 74(2) and that would get you 148. 360 - 148 is 212. 212/2 is 106. TADAAAAA. That's the answer.

12(2) + 4(6) = 24 + 24 = 48 = 6*8
Step-by-step explanation:
$12X + $6(4) = (X+4)*$8
12X + 24 = 8(x+4)
12x + 24 = 8x + 32
12x + 24 - 8x - 32 = 0
4x - 8 = 0
4x = 8
x = 8/4 = 2

you will get 3y=12+6=18
3y=18
y=6
now replace y=6
3x+12=6
3x=6-12
3x=-6
x=-2
(-2,6)
Answer:
(-2,6)
Step-by-step explanation:
3x + 2y = 6
-3x + y = 12
3x + -3x = 0
2y + y = 3y
6 + 12 = 18
3y = 18
3y/3 = 18/3
y = 6
-3x + y = 12
-3x + 6 = 12
-3x = 12 - 6
-3x = 6
-3x/-3 = 6/-3
x = -2

Answers
Answer:
3.25 degrees/hour
Step-by-step explanation:
Last night, the temperature fell from 0°F to -13°F in 4 hour.
We need to find the average temperature change per hour. It can be calculated by dividing the change in temperature per unit time.
Change in temperature = -13°F -0°F = -13°F
So,
[tex]C=\dfrac{-13}{4}\\\\=-3.25\ \text{degrees/hour}[/tex]
So, the change in temperature is 3.25 degrees/hour.
Answer:
-3.25 degrees an hour
Step-by-step explanation:
-13 ÷ 4 = -3.25
