Answer:
lacy = 8 jack= 24
Step-by-step explanation:
let x be lacys age
3x - 3 + x-3 = 14
3x+x -3 = 14 + 3 = 17
4x = 17 +3 = 20
x = 20/4 = 5
lacys age now = 5+3 = 8
jacks age now = 8 * 3 = 24
Answer:
Step-by-step explanation:
<u>Factor the expression:</u>
- 2y² + 21y + 10 =
- 2y² + 20y + y + 10 =
- 2y(y + 10) + (y + 10) =
- (y + 10)(2y + 1)
Answer:
5/7
Step-by-step explanation:
first of mean to divide
so it really saying x ÷ 3/4 and x = 15/28
15/28 ÷ 3/4 but you cant divide fractions
so we use copy dote flip
copy 15/28
dote ×
flip 4/3
15/28 × 4/3
then cross simplafiy so 4 can go into 28, 7 rimes. and 3 can go into 15, 5 times
5/7
Answer:
n=2
