I would word it ...

"nine times the sum of x and the square of y is eighteen".

As a math sentence, it looks like

... 9(y^2 +x) = 18

... 9(y² +x) = 18

I'm having trouble solving this I don't know the steps

Andreas93 [3]

Answer:

x=4

Step-by-step explanation:

21x+6+90=180

First, we need to subtract the numbers.

21x=180-90-6

21x=84

Now, we need to find the value for 1x, so divide the whole equation by 21

84/21

21/21

x=4

Hope this helps!

Solve the Equation for y . 9x +5y = -2

ASHA 777 [7]

Answer:

$\large\boxed{y=\dfrac{-9x-2}{5}}$

Step-by-step explanation:

$9x+5y=-2\qquad\text{subtract}\ 9x\ \text{from both sides}\\\\5y=-9x-2\qquad\text{divide both sides by 5}\\\\y=\dfrac{-9x-2}{5}$

James fenced in his backyard. The perimeter of his fence is 20 feet, and the width of his yard is 2 feet wide. Use the perimeter

Deffense [45]

Answer:

D. 96 inches

Step-by-step explanation:

Perimeter (P) = 2L + 2W , Where L is the length and W is the width.

20 ft = 2L + 2(2 ft)

2L = 20 ft - 4 ft = 16 ft

L = $\frac{16}{2}$ ft = 8 ft

1 ft = 12 inches

8 ft = ?

Cross-multiplying this gives; $\frac{8}{1}$ × 12 = 96 inches
