<u>Missing part of the question</u>

Hayley bakes zucchini bread and banana bread. Some ingredients Hayley uses for each type of  bread are shown in the tables

Zucchini Bread

2 eggs        2 cups of flour       1.5 cups of sugar        0.5 stick of butter

Banana Bread

1 egg          3 cups of flour        2 cups of sugar          0.25 stick of butter

Answer:

2z + b \le 9

2z + 3b \le 15

Step-by-step explanation:

Given

Flour  = 15

Egg =9

Since there are enough of other ingredients, we will only consider the amount of eggs and cups of flour.

So, we have:

Zucchini Bread

Egg = 2

Flour = 2  

Banana Bread

Egg = 1

Flour = 3

<u>For the eggs</u>

The ratio of eggs to use in the Zucchini bread to Banana bread is:

Egg = 2 (z) : Egg = 1 (b)

This gives:

2z + 1b

The total number of eggs cannot exceed 9.

So, the inequality is:

2z + 1b \le 9

2z + b \le 9

<u>For the flours</u>

The ratio of flours to use in the Zucchini bread to Banana bread is:

Flour = 2 (z) :    Flour = 3 (b)

This gives:

2z + 3b

The total cups of flours cannot exceed 15.

So, the inequality is:

2z + 3b \le 15

Hence:

The system of inequalities is:

2z + b \le 9

2z + 3b \le 15

250 in the account

3%x7=21%

0.21 times 250 = 52.5

250 + 52.5 = 302.5

Justin is asked to solve the following system of linear equations using the elimination method.
romanna [79]

Alright, lets get started.

Justin is asked to solve the linear equations using elimination method.

By using elimination method means we have to multiply some numbers in our given equations in such a way that the co-efficient of x or y become same in both equations so that we could add or subtract them to cancel one of the term either x or y.

So, given equations are :

5x - 12 = 3

-20x + 14 y = 13

See we have 5x in first equation and -20x in second equation.

So, we try to change 5x into 20 x by multiplying it with 4, both of the equations will have 20 x in common

Lets multiply 4 in first equation

4 * (5x-12y) = 4 * 3

20x - 48y = 12

Now both equations could be added and 20 x will be cancelled out and we could easily find the value of y then solve for x.

So, Justin should try to change 5 so that it will be cancels, so option B  :  Answer

Hope it will help :)
