You need to do 175 divided by 3.
Answer:
Laura is 8
Step-by-step explanation:
let Laura's age now be x then Daniel's age is 2x
4years ago
Laura was x - 4 and Daniel 2x - 4, thus
2x - 4 = 3(x - 4) ← 3 times Laura's age
2x - 4 = 3x - 12 ( subtract 2x from both sides )
- 4 = x - 12 ( add 12 to both sides )
8 = x
Thus Laura is 8 years old
Answer:
2+7x-15
Step-by-step explanation:
I presume f(x)=x+5 and g(x) =2x-3 and the question is f(x)*g(x)
f(x)*g(x)
(x+5)(2x-3)
distribute
2+10x-3x-15
2+7x-15
Answer: D. y-5= -7(x-8)
Step-by-step explanation:
point slope form: y-y1=m(x-x1)
slope= -7
point: (8,5)
use the slope and point and plug it into point slope form equation.
y-5= -7(x-8),
The Answer would be D. y-5= -7(x-8)
