Answer:
6 is 56.25
7 is 97.50
Step-by-step explanation:
Answer:
x=30
Step-by-step explanation:
1/2(x + 6) = 18
Distribute
1/2 x + 1/2 *6 = 18
1/2 x +3 = 18
Subtract 3 from each side
1/2 x +3-3 = 18-3
1/2 x = 15
Multiply each side by 2
2*1/2x = 15*2
x = 30
Answer:
2 divided by 22 equals 0.55. 8 divided by 15 equals 0.53. So runner A had a greater average speed.
Step-by-step explanation:
Answer:
x = 37
m∠a = 104°
m∠b = 76
Step-by-step explanation:
Two supplementary angles will add up to 180 degrees. We can create an equation and solve for x.
3x - 7 + 2x + 2 = 180
~Combine like terms
5x - 5 = 180
~Add 5 to both sides
5x = 185
~Divide 5 to both sides
x = 37
~Find the measure of angle A
3(37) - 7
104
~Find the measure of angle B
2(37) + 2
76
Best of Luck!
