Answer:

x = -1 and y = 1

Step-by-step explanation:

5x + 2y = -3 . . . . . . . (i)

x + 5y = 4 . . . . . . . (ii)

  • Finding x in terms of y from eq. (ii) :-

x + 5y = 4

x = 4 - 5y

  • Placing this value of x in eq. (i) :-

5(4 - 5y) + 2y = -3

20 - 25y + 2y = -3

-23y = - 23

<u>y = 1</u>

  • Placing the value of y in eq. (i)

5x + 2(1) = -3

5x + 2 = -3

5x = - 5

<u>x = -1</u>

Answer:

the answer is c) 182.25

Step-by-step explanation:

The information provided gives you a scale that will ultimately allow you to determine the height of the larger cylinder.

Since it tells us the two are similar, we can use the scale to solve for the second height.

Set up your math like this:

\frac{16}{h}=\frac{64}{729}

h represents the height you are trying to find.

using a common multiple, you can solve for h.

16 times 4 is 64. so 729 divided by 4 is 182.25

The value of the variable 'x' in the first case and the second case will be 9° and 1.

<h3>What is a parallelogram?</h3>

It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal. And the sum of the adjacent angles is 180°.

In part 61, the equation is given as,

100° + 9x - 1° = 180°

Simplify the equation, then we have

9x + 99° = 180°

9x = 81°

x = 9°

In part 62, the equation is given as,

22x - 1 = 21

Simplify the equation, then we have

22x - 1 = 21

22x = 22

x = 1

The value of the variable 'x' in the first case and the second case will be 9° and 1.

More about the parallelogram link is given below.
