1. we can add them to eliminate y's

3x-4y=-16
<u>-x+4y=24 +</u>
2x+0y=8

2x=8
divide by 2
x=4

sub back
-x+4y=24
-4+4y=24
add 4 both sides
4y=28
divide by 4
y=7

(x,y)
(4,7)




3.
add them to eliminate y's

-5x+3y=12
<u>-2x-3y=-33 +</u>
-7x+0y=-21

-7x=-21
divide both sides by -7
x=3

sub back
-2x-3y=-33
-6-3y=-33
add 6 to both sides
-3y=-27
divide both sides by -3
y=9

(x,y)
(3,9)

Kyle and his friends share some apple pie equally. Each person gets 7/5 of the pies. Which of the following shows a possible way
stiv31 [10]

Answer:

7 apples divided among 5 people

Step-by-step explanation:

Given

Apple shared equally

Portion of each person = 7/5

Required

A possible way that shows how the pies were shared.

Given that 7/5 is the ration of the pie to each individual (Kyle and his friends).

Provided that each individual got equal ration....

The ration can be divided into two

The numerator = 7

The denominator = 5.

The numerator shows the number of things that were shared.

Hence, 7 apples were shared.

The denominator shows the number of people involved.

Hence, 5 people were involved.

So, we can conclude that 7 apples were divided among 5 people.

From option A through D, only option B satisfied this analysis

A = 2√3 ft.;c = 4 ft.<br> A = 8√3 sq. ft.<br> True<br> False
Vladimir79 [104]

False . The equation a= 2√3 ft.;c = 4 ft is: A= 2√3 ft².

<h3>Area of the triangle</h3>

Given:

a = 2√3 ft,

c = 4 ft,


Lengths of the sides of a right triangle = a and b

Hypotenuse= c

Hence:

<h3>Using Pythagorean theorem</h3>

c²=a²+b²

4²=(2√3)²+b²

16=12+b²

4=b²

b=2

Area of triangle

A=1/2×a×b

A=1/2×2√3×2

A=4√3÷2

A=2√3 sq.ft

The Area of the triangle is 2√3 ft².
