Answer:
x = 5
Step-by-step explanation:
Also in this case we can use the Pythagorean theorem in this way
x^2 + (5√3)^2 = 10^2
x^2 + 75 = 100
x^2 = 25
x = +/- 5
we take only the positive value because a lenght can’t be negative
x = 5
The quotient is 5 because 2/10=5
Answer:
1.075 or 43/40
Step-by-step explanation:
3x +3(x-10) = 360
3x +3x-30 =360
6x-30 =360
6x=390
X = 390/6 = 65
65-10 =55
<span> One car was driving
65 mph</span>
<span> The other was 55
mph</span>
a = 56
given 28 = 
a
multiply both sides by 2 to eliminate the fraction
56 = a
As a check
× 56 = 28 ← True
