Answer:

x=1

Step-by-step explanation:

We distribute the negative 5 to x minus three to get 8x-5x+15=18. Then, we cancel out the 15 by subtracting it from both sides. This leaves us with 8x-5x=3. When we subtract, we get 3x=3, and when we divide both sides by 3, we get x=1. Hope this helps :)

24 is 16 multiplied by 1.5: 1.5*16=24

that means that we have to multiply all the amounts of the ingredients by 1.5 to keep the same ratio and make more gingerbread:

180 g flour*1.5=270 grams flour
40 g ginger *1.5=60 grams ginger
110 g butter *1.5 =165 gram butter
30 g sugar*1.5=45 grams sugar

I will mark the Best or first answer as brainliest.

It is between 3.1 and 3.17 or 3.2 if you want it by hundredths.

This is because 3.16 is 3.1600000 and many more zeros but 3.16227766 is slightly over that so it would be between 3.1 and 3.17.

EASY MATHS PLS HELP

Fofino [41]

Answer:

(1.25, - 5 )

Step-by-step explanation:

Given the 2 equations

- 4x + 3y = - 20 → (1)

4x + 2y = - 5 → (2)

Adding the 2 equations term by term will eliminate the x- term

5y = - 25 ( divide both sides by 5 )

y = - 5

Substitute y = - 5 into either of the 2 equations and solve for x

Substituting into (2)

4x + 2(- 5) = - 5, that is

4x - 10 = - 5 ( add 10 to both sides )

4x = 5 ( divide both sides by 4 )

x = $\frac{5}{4}$ = 1.25

Solution is (1.25, - 5 )
