Box a contained 1.67 kg of flour. box b contained 8600 g of flour. after same amount of
flour was added to each box, box b contained 4 times as much flour as box a. how
much flour was added to each box? give your answer in kg.

The amount of flour added to each box was 0.64 kg

Step-by-step explanation:

Let

x > the amount of flour added to each box in kg

Remember that

1 kg=1,000 g

8,600 g=8,600/1,000=8.6 kg

we know that

The linear equation that represent this situation is

(8.6+x)=4(1.67+x)

Solve for x

8.6+x=6.68+4x

4x-x=8.6-6.68

3x=1.92

x=0.64 kg

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

both graphs increase on their domain

neither graph has a y-intercept
