Answer:
The ratio of boys to girls to 5:7
Let the number of boys be 5x
Let the number of girls be 7x
5x = 30
x = 6
Now just plug in 6 for the x in 7x
and number of girls 7 x 6 = 42
Answer:
a+15=x
Step-by-step explanation:
Austin is represented as variable a, and you have 15 more cards.
x is your amount of cards
Answer:
x = 2
Step-by-step explanation:
5x - 2 = 10 - x
<em>Add x to both sides</em>
6x - 2 = 10
<em>Add 2 to both sides</em>
6x = 12
<em>Divide both sides by 6</em>
x = 2
Answer:
1/2
Step-by-step explanation:
8(1/2)^4
= 8 * 1 / 2^4
= 8/(2*2*2*2)
= 8/16
= (8*1) / (8*2)
= 1/2
(HoG)(x) = (2x)2 + 4 simply because HoG(x) is actually H(G(x)). So where ever there was an x in H(x) we substitute our value of G(x). Now the only thing left is to put in the 1. so out answer is (2(1))2 + 4 = 8Only in the 6th grade ; )
