Answer:
18
Step-by-step explanation:
you always do the parenthesis first
10-7=3
6x3=18
Answer:
The equation would be y = 2x - 8
Step-by-step explanation:
The equation of the line would have a slope of 2, since parallel lines have the same slope. We can use that and the point in point-slope form to find the equation.
y - y1 = m(x - x1)
y + 2 = 2(x - 3)
y + 2 = 2x - 6
y = 2x - 8
Answer: the cost of admission for each child is $10
the cost of admission for each adult is $14
Step-by-step explanation:
Let x represent the cost of admission for each child.
Let y represent the cost of admission for each adult.
The cost of admission to a popular music concert was 162 dollars for 12 children and 3 adults. This is expressed as
12x + 3y = 162- - - - - - - - - - - - -1
The admission was 122 dollars for 8 children and 3 adults in another music concert. This is expressed as
8x + 3y = 122- - - - - - - - - - - - -2
Subtracting equation 2 from equation 1, it becomes
4x = 40
x = 40/4
x = 10
Substituting x = 10 into equation 1, it becomes
12 × 10 + 3y = 162
120 + 3y = 162
3y = 162 - 120
3y = 42
y = 42/3
y = 14
