Answer:
x = -12
Step-by-step explanation:
Let x be the number.
The product of 5 and x increased by 9 is equal to 15 less than 3 times x.
5x + 9 = 3x - 15.
We can isolate x, getting (5-3)x = -15-9
Then we can solve:
2x = -24
x = -12.
Answer:
704 square yards
Step-by-step explanation:
10 * 19 = 190

6 * 8 = 48
48 * 2 = 96
96 + 228 + 380 = <em><u>704</u></em>
