5/7 = x/56....5 boys to 7 girls = x boys to 56 girls
cross multiply
(7)(x) = (56)(5)
7x = 280
x = 280/7
x = 40......there were 40 boys on the school trip
Answer: 2.7 inches long
Step-by-step explanation:
cross multiply
1 * x = 13.5 * 0.2
x = 2.7
Use PEMDAS
5) -6(12 -15) + 2^3
Parenthesis first: -6(-3) + 2^3
Exponent: -6(-3) + 8
Multiplication: 18 + 8
Addition: 26
26 is the final answer for #5
6) -50 / (-10) + (5 - 3)^4
Parenthesis: -50/-10 + (2)^4
Exponent: -50/-10 + 16
Division: 5 + 16
Addition: 21
21 is the final answer for #6
So if it's reflected directly across the x axis, the original point had to be (7.5,6), meaning both points are 7.5 units from the origin. since it's reflected you will add them together.
so your answer is 15 units :)
Answer: 6 or 0.6
