I would have to see the shape to see this but I could say the volume if you'd want. 5*6*7= 210. And don't forget; you can find the surface area by doing b x h if it's a rectangle. And if it's a triangle do b x h / 2

Solve the system of equations 5x-2y=88 3x+4y=58 show all work
diamong [38]
The given equations are:

5x - 2y = 88
3x + 4y =  58

Multiplying the 1st equation by 2, we get the new set of equations as:

10x - 4y = 176
3x + 4y = 58

Adding the two equations, we get:

10x - 4y + 3x + 4y = 176 + 58
13x =234
x =  18

Using the value of x in 1st equation, we get:

5(18) - 2y = 88
- 2y = 88 -5(18)
-2y = -2
y = 1

So, the solution of the equation is (18, 1)

kolezko [41]

Answer: A)There are 5 nonfiction books for every 9 fiction books in the library.

5*21=105 and 9*21=189 it is not B because the smaller number 105 is in front of the ratio 105:189 and 5:9

PLEASE HELP<br> A) 8<br> C) 1<br> B) 6<br> D) 7<br><br> What is the value of x?
SVEN [57.7K]

Answer: 7

Step-by-step explanation:

As tangents drawn from a common external point to a circle are congruent,

  • 8x - 7 = 6x + 7
  • 2x - 7 = 7 [subtract 2x from both sides]
  • 2x = 14 [add 7 to both sides]
  • x = 7 [divide both sides by 2]

Find the area of a square that has a side that measures 5 mm.
Oksanka [162]

Answer:

25 mm^2

Step-by-step explanation:

Because the sides of a square are all equal, that means the length = 5 and the width = 5.

To find the area, you do length * width so for this square it would be 5 * 5 = 25.
