Answer:

47-Step-by-step explanation:

X=121 because they are vertical angles

48- first divide 96 by 6 together the surface area of each side which is equal 16 then to find the length and the width find the square root of 16 which is 4 because it is a cube the length/width/height are all equal to four. So do 4 x 4 x 4 to find the volume of one cube. Which is equal to 64 then multiple by 8 to get the total volume 512cm^3

Brenda mails a package to a grandson that weighs 210 grams. About how many ounces is the package? Use 1 ounce = 28.4 grams.

Lilit [14]

210 grams into ounces
210 / x = 28.4 / 1
cross multiply
210 = 28.4 x
divide both sides by 28.4
The answer is <span>7.39 ounces
That can be rounded to 7.4 ounces

The package is 210 grams or 7.4 ounces.

Hope this helps :)</span>

What is the value of x?

lilavasa [31]

The little rectangle in the top right means the angle is a right angle which equals 90 degrees.

This also means all the other angles are also 90 degrees.

Solve for x:

2x+8 = 90

Subtract 8 from both sides:

2x = 82

Divide both sides by 2:

x = 82/2
