Answer: 3/8ths
Step-by-step explanation: 1/8+1/8+1/8=3/8
Answer:
48
Step-by-step explanation:
x/3 - 6 = 10
+6 +6
x/3=16
16*3=48
Answer: 55
Step-by-step explanation: There is one simple theorem we need to know in order to solve for this.
Triangle Angle-Sum Property: All three angles interior angles of a triangle add up to 180°.
Thus, we could label the points A, B, and C, and set up an algebraic expression.
Let A = 27, B = 98, and C = x.
A + B + C = 180°.
Substituting A, B, and C we get:
27 + 98 + x = 180°.
Adding, we get:
125 + x = 180°
Subtracting 125 by 180, we get:
x = 55°
Thus, the angle X is 55°.
We could have simply solved this by just doing 180 - 98 - 27 = 55 in the first place, but I wanted to show you how I got such results.
Answer:
x = 4
Step-by-step explanation:
Given
= 
( cross- multiply )
4x - 7 = x + 5 ( subtract x from both sides )
3x - 7 = 5 ( add 7 to both sides )
3x = 12 ( divide both sides by 3 )
x = 4
Answer:
$880
Step-by-step explanation:
This is called a system of equations!! Here's how to do it:
1. Make Equations
In this case, the equations would be
- p+c=64 (this is saying that pepperoni pizzas plus cheese pizzas equal 64, which we got from the question.)
- 1/3c=p (this is telling us that he sells 1 pepperonis for 1/3 cheese pizza)
2. Solve the system of equations
For this problem, we will substitute 1/3c for p. The problem becomes
Then you divide by 4/3 to get p by itself:
Now substitute 48 for p in the first equation.
3. Find the money amounts
Now that you know that pepperoni pizzas equal 48, and cheese equals 16, this is easy.
- Multiply 16*10 to get the cheese cost. ($160)
- Multiply 15*48 to get the pepperoni cost ($720)
- Then add those to get the total!
