Answer:

Ordered pair (x,y) is (6,2)

Step-by-step explanation:

Use the substitution method to solve the system of equations.

2x + 2y = 16    -----> first equation

y=x-4 -------> second equation

Divide the first equation by 2

2x + 2y = 16    -----> first equation

x+y=8    

Now solve for y, subtract x from both sides

y=-x+4    

Now plug in -x+8 for y in second equation

y=x-4 -------> second equation

-x+8=x-4  

Subtract x from both sides

-2x+8=-4  

Subtract 8 on both sides

-2x=-12  

Divide both sides by -2

x=6

now we plug in 6 for x in second equation

y=x-4 -------> second equation

y=6-4

y=2

Ordered pair (x,y) is (6,2)

16. Suppose Eva has 12 3/4 pounds of flour. The day's baking will require triple that amount.
egoroff_w [7]

Answer:

Option D

Step-by-step explanation:

Given the following question:

12 \frac{3}{4} \times3

In order to find the answer, we have to convert the mixed number and then multiply by three, since how Eva needs triple the amount for today's baking.

12 \frac{3}{4} \times3
12\frac{3}{4} =4\times12=48+3=51=\frac{51}{4}
3=\frac{3}{1}
\frac{51}{4} \times\frac{3}{1}
51\times3=153
4\times1=4
=\frac{153}{4}

<u>Convert the improper fraction back into a mixed number:</u>

\frac{153}{4}
\frac{153}{4} =153\div4=38\frac{1}{4}
=38\frac{1}{4}

Which means Eva needs "38 1/4 pounds of flour" or option D for today's baking.
