3) Solve the System of Equations using Elimination/Combinations. (5 points)

Schach [20]

Answer:

(1, 2 )

Step-by-step explanation:

Given the 2 equations

- 2x - y = - 4 → (1)

x + 2y = 5 → (2)

Multiplying (2) by 2 and adding result to (1) will eliminate x- term

2x + 4y = 10 → (3)

Add (1) and (3) term by term to eliminate x

0 + 3y = 6

3y = 6 ( divide both sides by 3 )

y = 2

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

Substituting into (2)

x + 2(2) = 5

x + 4 = 5 ( subtract 4 from both sides )

x = 1

solution is (1, 2 )

I REALLY NEED HELP PLEASE!!

Answer:

To me the triangles in #6 appear to be the same shape as the first triangle in #7(EFG) with different lengths on the sides. But not much else is the same. I mean they are all triangles but the shape of the second triangle in #7(XYZ) isn't the same as either of the triangles in #6.

I hope that made sense to you!

Hope this helped! Have a great day! :)

schepotkina [342]

Answer:

Step-by-step explanation:

Given:

Brett orders 2 meatball,1 turkey,1 veggie party-size sandwiches.

Each sandwich costs the same amount.

The total amount cost of the sandwiches, including tax, is $54.36.

Question asked:

What is the cost of each sandwich including tax?

Solution:

Let cost of each sandwich including tax = $x$

Total number of sandwich = 2 + 1+ 1 = 4

As each sandwich costs the same amount and total amount of cost of 4 sandwiches, including tax, is $54.36, the equation will be:-

$x+x+x+x=\$54.36\\4x=\$54.36$

By dividing both sides by 4,

$x=\$13.59$

Thus, the cost of each sandwich including tax is $13.59

Nina saves 40% of her summer job earnings for college. This summer, she earned $200 more than last summer, and she saved $900. W

beks73 [17]

Answer:

(900 ÷ 4) x 10 -200 = 2050 And this will equal last Summer's earnings

Step-by-step explanation:

So we know that 900$ is equal to 40% and that we can simplify this

900 ÷ 4 = 225

40% ÷ 4 = 10%

Therefore:

225 = 10% and

2250 = 100% of earnings
