Answer:
Step-by-step explanation:
Sean buys some T-shirts for $12 each and the same number of belts for $7.50 each. Write an expression in the simplest form that represents the total amount.
So n represents the same number for t-shirts and belts.
Therefore n x 12.50 + n x 7.50 OR n(12.50+7.50)
The problem the student made was that they multiplied 12 times n plus 7.50. They forgot to multiply n times 7.50.
An expression that represents the total amount spent is 12n + 7.50n

When 2 lines cross the angles across from equal are equal so the 31 degree angle is the value of the second angle in the left hand triangle. You now have 2 angles with values of 31 degrees 33 degrees. Add these 2 together to get 64 degrees. To get the third angle subtract this from 180 degrees which is the total degrees in a triangle. The third angle is 116 degrees. When two angles are on one side of a straight line, their sum is 180 degrees. That is true of the two bottom angles in the triangle on the right. You need to subtract each of the known angles from 180 degrees. 180 - 116 = 64 and the other is 180 - 96 = 84. To find angle x add these 2 angles and subtract from the total number of degrees in a triangle which is 180 degrees. 84 + 64 = 148. Subtract from 180. X = 32.

Answer:
Volume of prism is equal to units
Step-by-step explanation:
let the side of the cube be of one unit.
Then, the area of the base is equal to connecting cubes
Assuming a square base of the rectangular prism.
Length of one side of the base of rectangular prism units
Similarly, width of the base of rectangular prism units
The height of the rectangular prism is units
Volume of the prim Length Width Height
Substituting the given values in above equation, we get -
Volume of prism is equal to units
