Answer:
see below
Step-by-step explanation:
4x - 4(30-2x)=24
4x-120+8x=24
12x=144
X=12
then substitute
2(12) + y =30
y=30-24
y=6
Answer:
24. a) ⅞ b) 1⅘
17. 36
Step-by-step explanation:
24.
a) ½ × ¾ + 3/2 × ⅓
3/8 + 1/2
(3 + 4×1)/8
7/8
b) 1½ ÷ (1½ - ⅔)
3/2 ÷ (3/2 - 2/3)
3/2 ÷ (3×3 - 2×2)/6
3/2 ÷ 5/6
3/2 × 6/5
18/10
1 8/10
1⅘
17. 1 day = 24 hours
1.5 days = 1.5× 24= 36 hours
Let x be the total price. And you paid 75% of it which is $135.
x * 75/100 = 135
x = 180
You would have paid $180 if you had not used coupons.

Answer:
no solution
Step-by-step explanation:
Solve:
6(2k + 1) = 12k + 1
Expand brackets:
⇒ 12k + 6 = 12k + 1
Subtract 12k from both sides:
⇒ 6 = 1
As 6 ≠ 1 there is no solution
