Answer:
13
Step-by-step explanation:
$45=3.50x
divide both sides by 3.50
13 movies (rounded to nearest whole number)
3(x-2)=3x+6
distributed 3 to the parentheses
3x-6=3x+6
now use inverse operation and subtract 3x from both sides
you get -6=6 which makes the statement false
2(x - 3) ≤ 16. Youre welcome
Answer:
a complementary angle adds up to 90 degrees.So 90 minus 64 and the measure of the other angle is 26
Step-by-step explanation:
Hope it helped ;)
We can use ratios and the cross-multiply-divide to find this.
The ratio 21:5 is avaliable via the question. We then need to compare that to the ratio x:100, the 100 being the percent and the x being the number of airplane parts.
21/5 = x/100
We can then solve for x to find the number of airplane parts. First we multiply by 100 on both sides to get 2100/5 = x. Therefore x = 420 and there are 420 airplane parts.
