Answer:
60 degrees.
Step-by-step explanation:
Answer:
y= cost of a popcorn
x= cost of a drink
3x+2y=45
9x+3y=110.25
y= 8.25
x= 9.5
popcorn= $8.25
drink= $9.50
Step-by-step explanation:
Answer: 62+63+64
Step-by-step explanation:
Divide 189 by 2. That gives you 63. Then go for a number 1 above it and 1 below it.
Answer:
1
Step-by-step explanation:
The coefficient is the number in front of the variable. Since there is not a number written, there is an implied 1
x+4
1x+4
The coefficient is 1

4[2y + -3] + -1 = 11
Reorder the terms:
4[-3 + 2y] + -1 = 11
[-3 * 4 + 2y * 4] + -1 = 11
[-12 + 8y] + -1 = 11
Reorder the terms:
-12 + -1 + 8y = 11
Combine like terms: -12 + -1 = -13
-13 + 8y = 11
Solving
-13 + 8y = 11
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '13' to each side of the equation.
-13 + 13 + 8y = 11 + 13
Combine like terms: -13 + 13 = 0
0 + 8y = 11 + 13
8y = 11 + 13
Combine like terms: 11 + 13 = 24
8y = 24
Divide each side by '8'.
y = 3
Simplifying
y = 3</span>
