Answer: 91/22 that would be your answer
Answer:
£24 : £32
Step-by-step explanation:
Add the parts of the ratio 3 + 4 = 7
Divide the amount by 7 to find the value of one part
£56 ÷ 7 = £8 ← one part of the ratio
3 parts = 3 × £8 = £24
4 parts = 4 × £8 = £32
Answer:
x=5
Step-by-step explanation:
write x - 4 as a fraction with denominator = 1
5/x = (x - 4)/1
Now cross multiply
x(x - 4) = 5 multiply out and collect all terms on the left side of the equal sign
x2 - 4x - 5 = 0 factor the quadratic into two binomials
(x - 5)(x + 1) = 0 the product of two numbers = 0 when either number is zero
Therefore x = 5 or x = -1
Answer:
-20 or +4
Step-by-step explanation:
(x+20)*(x-4)=0
x+20=0 or x-4=0
X= -20 or +4
