<span>8 dogs received a chew toy, and five dogs received a rubber ball
There are 13 dogs in all. Each of the dogs received either a chew toy or a rubber ball. If three more dogs received a chew toy than a rubber ball, the only possible answer is: 8 dogs received a chew toy, and five dogs received a rubber ball. 8 dogs plus 5 dogs equals 13 dogs in all. And 8 chew toys is three more than five rubber balls.</span>
Answer:
x = 10/7 or x = -10/7
Step-by-step explanation:
By using the completing the squares method, we have to divide the coefficient of the x term by 2, square it and add to both sides
From what we have here, the coefficient of the x term is 0
Thus, we have it that;
0 = 100 - 49x^2
We can proceed to use the difference of two squares here;
Whereby;
a^2 - b^2 = (a-b)(a + b)
0 = (10-7x)(10+7x)
10 - 7x = 0 or 10 + 7x = 0
7x = 10 or 7x = -10
x = 10/7 or x = -10/7

Answer:
3x +3
Step-by-step explanation:
5 + 3x - 2
