If jill and katie share 42 chocolates in the ratio of 3:4 then how may chocolates does jill get?

nasty-shy [4]

Answer:

jil got 18 chocolates

Step-by-step explanation:

let the ratio constants be x,

so, jil has 3x chocolates

katie has 4x chocolates

and we know total chocolates = 42

then,

=》3x + 4x = 42

=》7x = 42

=》x = 42 ÷ 7

=》x = 6

so, jil got 3x = (3 × 6) = 18 chocolates

katie got 4x = (4 × 6) = 24 chocolates

Write a system of equations to describe the situation below, solve using any method, and Fill in the blanks.

Tatiana [17]

Answer:

1 haircut = 47 dollars

1 colouring = 98 dollars

Step-by-step explanation:

Let $x$ be equal to the cost of 1 haircut.

Let $y$ be equal to the cost of 1 colouring treatment.

<u>1) Form equations</u>

Equation 1: 3 haircuts + 1 colour = 239 dollars

⇒ $3x+y=239$

Equation 2: 2 haircuts + 1 colour = 192 dollars

⇒ $2x+y=192$

<u>2) Solve the system of equations</u>

Subtract equation 2 from equation 1 to cancel out y (elimination)

- $3x+y=239\\2x+y=192$

⇒ $3x-2x+y-y=239-192\\x=47$

Therefore, Natalie charges 47 dollars for 1 haircut.

Plug x back into one of the equations to solve for y

$2(47)+y=192\\94+y=192$

Subtract both sides by 94

$94+y-94=192-94\\y=98$

Therefore, Natalie charges 98 dollars for 1 colouring treatment.

I hope this helps!
