10°C×9/5+32
= 50°F
so the answer is 50
Answer:
x+85 + x+105 = 180
x = -5
x+85 = -5+85 = 80
x+105 = -5+105 = 100
Step-by-step explanation:
The two angles form a straight line so they add to 180
x+85 + x+105 = 180
Combine like terms
2x + 190 = 180
Subtract 190 from each side
2x+190-190 = 180-190
2x = -10
Divide by 2
2x/2 = -10/2
x = -5
x+85 = -5+85 = 80
x+105 = -5+105 = 100
13)
x+20 add x+21 = 23
41 + 2x = 23
2x =23 - 41
2x = -18
x = -9
x equals minus nine
15)
2x + 26 = x +20
2x - x = 20 - 26
x = -6
