.On 1st March 2001, the ratio of Freddie’s age to his mother’s age was 1:11 On 1st March 2018, the ratio of Freddie’s age to his mother’s age was 2:5
Write the ratio of Freddie’s age to his mother’s age on 1st March 2030

Step-by-step explanation:

Let

x = Freddie's age and y = His mother's age

Given

2001:=  

2018:=

Required

The ratio of their age in 2030

Express as fractions

--- (1)

-- (2)

In (1), make y the subject

Substitute in (2)

Cross Multiply

Collect like terms

This means that: In 2001, Freddie was 3 and his mother was 33

In 2030 (29 years after);

Freddie will be: 3 + 29 = 32

His mother will be: 33 + 29 = 62

So, the ratio is:

Divide by 2

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

5x+2x=49

7x=49

x=7. 35 apples
