Y=x-5 y=7 solve for x simplify your answer as much as possible

Mathematics
1 answer:
love history [14]2 years ago
5 0

Answer:

x = 12

Step-by-step explanation:

First of all, what you will want to do is plug in your y into the first equation, to find the x.

y = x - 5 ----> 7 = x - 5

Next, think about your possible solutions here.... Flip the equation:

5 + 7 = ? ---> 5 + 7 = 12

Now, plug both your x and y in the original equation:

7 = 12 - 5  Does this match?

7 = 7          Yes!

This is the simplest way I can explain it! I hope it is understandable, correct, and helpful. Have a great day :D

The perimeter of a rectangle is about 13.9 cm. If you double the width of the rectangle the perimeter is about 17.8 cm. Find the
fredd [130]

Answer:

5cm by 1.95cm

Step-by-step explanation:

Let the length of the rectangle be x

Let the width be y

Perimeter of a rectangle = 2x + 2y

If the initial perimeter of a rectangle is about 13.9 cm, then;

13.9 = 2x + 2y ..... 1

If when the width is double the perimeter is 17.8cm, then;

17.8 = 2x + 4y ..... 2

Subtract 1 from 2;

13.9 - 17.8 = 2y - 4y

- 3.9 = -2y

y = 3.9/2

y = 1.95 cm

Substitute y = 1.95 into 1 to get x;

From 1;

13.9 = 2x + 2y

13.9 = 2x + 2(1.95)

13.9 = 2x + 3.9

2x = 13.9-3.9

2x = 10

x = 5 cm

Hence the dimension of the smaller triangle is 5cm by 1.95cm
