If you would like to solve 1/4 * 4/7, you can do this using the following steps:
<span>1/4 * 4/7 = (1 * 4) / (4 * 7) = 4/28 = 1/7
</span>
The correct result would be 1/7.
1. 27 - 3 (because 3 are left over) = 24. Then, 24 ÷ 6 = 4 children.
2. If Mina has £7.20, that means she has 720 pence. If half is given to her brother, then she has £3.60 left. (720 ÷ 2 = 360 pence, which is £3.60)
3. 17 × 10 = 170
2 × 20 = 40
170 + 40 = 210, which is £2.10
Answer:x=-5 and x=3
Step-by-step explanation:
log(x^2-15)=log(2x)
Cancel log at both sides we get
x^2-15=2x
Collect like terms
x^2-2x-15=0
x^2-3x+5x-15=0
x(x-3)+5(x-3)=0
(x+5)(x-3)=0
x+5=0 x-3=0
x=-5 x=3
