Answer:
x = - 15
Step-by-step explanation:
Given
[tex]\frac{x}{5}[/tex] = 5 + [tex]\frac{x-9}{3}[/tex]
Multiply through by 15 ( the LCM of 5 and 3 ) to clear the fractions
3x = 75 + 5(x - 9) ← distribute and simplify right side
3x = 75 + 5x - 45
3x = 5x + 30 ( subtract 5x from both sides )
- 2x = 30 ( divide both sides by - 2 )
x = - 15
As a check
substitute x = - 15 into the equation and if both sides are equal then it is the solution.
left side = [tex]\frac{-15}{5}[/tex] = - 3
right side = 5 + [tex]\frac{-15-9}{3}[/tex] = 5 + [tex]\frac{-24}{3}[/tex] = 5 - 8 = - 3
Thus x = - 15 is the solution

Matthew needs 360g of flour
Answer:
360g flour
Step-by-step explanation:
10 pancakes need 120g of flour.
30 pancakes need x g of flour.
To find x, you first find the ratio between the pancakes and flour.
120g flour / 10 pancakes = 12 g flour needed per pancake
So if you have 30 pancakes,
12g of flour is needed per pancake * 30 pancakes
= 360g of flour is needed for 30 pancakes

Answers
Answer:
T is equal to I divided by pr. [tex]t=\frac{I}{pr}[/tex]
Step-by-step explanation:
This is the equation for interest.
I is interest.
P is the principal
r is the interest rate
t is the time in years
you have to isolate for t.
Because multiply p times r times t, divide both sides by pr due to the fact that division is the inverse operation of multiplication
Then you are left with t= i divided by pr.

Peter and Jane have some money in the ratio 1:3
Jane has £12 more than Peter how much money does Peter have?
Answers
Jane=3x
3x-x=12
X=6
Answer:
Peter has 6 dollars.
Step-by-step explanation:
The ratio is 1:3, meaning Jane has 3x more money than Peter. Or, Peter has 1/3 as much money as Jane. You know that Jane has 12 dollars more than Peter so you can think of scenarios. Because it is a 1/3 the answer for Peters money has to be 1/3 of Janes, so Peter has 6 dollars, and Jane has 12 more, so Jane has 18 dollars.
