Answer:
x=8
Step-by-step explanation:
Since this is an isosceles triangle <A is equal to <C
<A = <C = 69
<A+ <B +<C = 180 because the 3 angles of a triangle add to 180 degrees.
69 + 5x+2 + 69 = 180
Combine like terms
140+ 5x = 180
Subtract 140 from each side
140-140 +5x =180-140
5x = 40
Divide by 5
5x/5 =40/5
x=8
Answer:
46+46 = 92
180-92 = 88
x = 88
Step-by-step explanation:
15/50 = 3/30 = 1/10
1/10 = 10%
That is about as simple as I could put it.
C, d, and e is the answer
Answer:
A: 68.25 minutes
B: 12 times
C: 42 mins and you decide this part I actually don't know. But I think it could be reasonable, after 40 times someone should get pretty good at it.
Step-by-step explanation:
a: 72 -0.75*5 = 68.25
b: M=63=72-0.75n
subtract 72 from each side: -9 = -0.75n
divide each side by -0.75: n = 12
so 12 times
c: 72 - 0.75(40) = 42 minutes. Now this could be is reasonable, but we don't know what their desert is. But 40 times is a lot of practice.
