You said that 8c + 5 = 4c - 11
Subtract 4c from each side: 4c + 5 = - 11
Subtract 5 from each side: 4c = - 16
Divide each side by 4 : c = - 4
Answer:
Step-by-step explanation:
Is 1.450 correct? 145 would make more sense. I'd even go with 1,450, just for a laugh. I'll assume 1.450 is the correct number here. I'll assume assute the question eventually asks how old are A and B.
A = 49(B)
A+B=1.450
Substitute:
49B+B=1.450
50B = 1.450
B = 0.029
A = 49(B)
A = 49*(0.029)
A = 1.421
Answer:
The diagonal length of the square equals:
diagonal ^ 2 = 7^2 + 7^2
diagonal ^ 2 = 49 + 49
diagonal ^ 2 = 98
diagonal = 9.899 cm
The diagonal is smaller than the circle's diameter and so it will ft inside the circle.

Answer:
Step-by-step explanation:
There are both positive and negative values to substitute for x in x2 = 9. In the positive numbers, 32 = 9, so x = 3 is a solution. In the negative numbers, -32 = 9, so x = -3 is also a solution. The solutions for x2 = 9 are 3 and -3.
<h3>Answer:</h3>
6 in
<h3>Explanation:</h3>
Let M be the midpoint of AB. ∆CMB and ∆CMA are both isosceles triangles, so CM = (AB)/2 = 9 in.
CG = (2/3)(CM) = (2/3)(9 in)
CG = 6 in

<em>Comment on centroid and median</em>
The centroid of a triangle is located 1/3 the distance from the midpoint of a side to the opposite vertex. This is true for any median in any triangle. The proof can be developed from the fact that every median divides the triangle's area in half. Here, we just take advantage of this fact.
