Answer:

X=2

Explanation: simultaneous equations
4x-5y=-22.....1

-2x+5y=26.....2

Add equation 2 to equation 1

2x=4

Divide both sides by two

X=2

Answer:

My total savings was = $58.33

Step-by-step explanation:

Given:

12% of my savings was = $7.00

To find my total savings.

Solution:

Let the total savings in dollars be = $x$

12% of the total savings will be = $12\%\ of\ x$

12% of my savings was = $7.00

So, we have:

$12\%\ of\ x=7$

$0.12x=7$

Solving for $x$ to get my total savings.

Dividing both sides by 0.12

$\frac{0.12x}{0.12}=\frac{7}{0.12}$

∴ $x=58.33$

Thus, my total savings was = $58.33

Solve the below: 4x+3y=7 3x-2y=9

Ahat [919]

4x+3y=7
3x-2y=9

12x+9y=21
12x-8y=36
^^Multiply top equation by 3 and multiply bottom equation by 4

12x+9y=36
- 12x-8y=36

17y=-15
^^Then subtract those two new equations

17y/17= -15/17

Y= -0.88
^^Next divide both sides by 17

4x+3* -0.88=7

4x + (-2.64) =7
-(-2.64) -(-2.64)

4x = 9.64

4x/4=9.64/4
X=2.41

^^then choose on equation and put your new y in the y spot and solve.

X=2.41

Y=-0.88

Your point/coordinate is (2.41,-.88)

The perimeter of a triangle is 32 feet. One side of the triangle is 3 times the second side. The third side is 12 feet longer

Ivenika [448]

We have a triangle whose perimeter is 32 feet. Some information regarding the sides of the triangle is given:

GiveN:

One side is 3 times the second side.
Third side is 12 feet longer than the second side.

As we can see that, two sides of the triangle are defined the second sides. It means First and third side can be expressed in the form of second side.
