Because QRST is a rectangle, that means all of the angles must be a right angle, which are 90 degrees. Using this information, solve the expression by creating an equation that lets angle S = 90.
90 = 7x + 55
35 = 7x
x = 5
First find the area of the triangle shape:
Area of a triangle = 1/2 x base x height:
Area = 1/2 x 4 x 3 = 6 square cm.
For the volume multiply the area by the depth:
6 x 2 = 12 cubic cm
To solve an inequality, get the variable you're solving for on one side of the inequality and everything else on the opposite side.

You get the x variable on it's own by undoing the operations done to it.
For example, if x is being multiplied by 5, you undo the multiplication operation by using the inverse of multiplication. Which is division.
We need to add

to both sides of the inequality to undo the subtraction operation done to x.

Convert the improper fraction into a mixed number.

So, D 1 1/5 ≥ x is the answer.
For both GCF and LCM you find something in common.There is nothing else similar but only differences

Required:
Lemons used in first 4 hours
First, we calculate the number of lemon sold in the first 4 hours.


Represent the number of cups of lemonades needed with x
So, we have:

and

Cross Multiply:


Make x the subject
