4x + 3 = -5x - 7 Add 5x to both sides.
4x + 3 + 5x = -5x - 7 + 5x
9x + 3 = -7 Subtract 3 from both sides.
9x + 3 - 3 = -7 - 3
9x = -10 Divide both sides by 9
9x / 9 = -10 / 9
Your answer can either be 1.11111... or it would be x = -10/9
Answer:
Cost of ordering t-shirts the same at both sides is 7
The cost is $85
Step-by-step explanation:
let x equal the number of tshirts
Hence:
15 + 10x = 50 + 5x
10x-5x= 50-15
5x = 35
35/5x
x = 7
Therefore the cost of ordering t-shirts the same at both sides is 7
The cost is $85
Answer:
the answer is 126 because 9 times 14 is 126
Answer:
$1.66 per foot
Step-by-step explanation:
3 yards=9 ft
14.94/9=$1.66 per foot
x ^ 2 - 18 = 0
For this case, the first thing you should do is rewrite the expression:
x ^ 2 - 18 = 0
x ^ 2 = 18
The solutions for this case are:
x1 = root (18)
x2 = -raiz (18)
Therefore the answer is:
2 solutions of real numbers.
Answer:
2
