Answer:
x<13
Step-by-step explanation:
4x+12<64
Subtract 12 from both sides.
simplify 64 to 52.
Divide both sides by 4.

The equation of the line that is parallel to the line 5x + 2y = 12 and passes through the point (-2, 4) is y = [tex]-\frac{5}{x} x-1[/tex]
Parallel lines
Parallel lines have the same slope. Therefore, using slope intercept form.
y = mx + b
m = slope
b = y-intercept
Therefore,
5x + 2y = 12
2y = -5x + 12
[tex]y = -\frac{5}{2} x+12[/tex]
The slope of the line is [tex]-\frac{5}{2}[/tex]
Base on parallelism, for the line that passes through (-2, 4)
y = mx + b
4 = [tex]-\frac{5}{2} (-2)+b[/tex]
b = -1
Therefore,

One-half of a number,
increased by 69 is 74.
What is the number?
Answer:
10
Step-by-step explanation:
let the number be n then half the number is [tex]\frac{1}{2}[/tex] n , so
[tex]\frac{1}{2}[/tex] n + 69 = 74 ( subtract 69 from both sides )
[tex]\frac{1}{2}[/tex] n = 5 ( multiply both sides by 2 to clear the fraction )
n = 10
Thus the number is 10

mark and heather starr are celebrating their 25th anniversary by having a reception at a local reception hall. they have budgeted $3,000 for their reception. if the reception hall charges a $50 cleanup fee plus $32 per person, find the greatest number of people that they may invite and still stay within their budget.
Mark and heather can invite at most __ people to the reception.
Answer:
i think 90 people
Step-by-step explanation:
3,000 - 50 (clean up fee) - 64 (mark and heather) = 2886
32 x 10 = 320 ( cost of ten people )
2886 - (320 x 9) = 6

What is expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division.
An expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it. Let us understand how to write expressions. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression.

angle 3 and angle 4 are supplementary. m<3=7x-3 and m<4=2x+12. Find the measure of each angle
Step-by-step explanation:
Sum of supplementary angle = 180⁰
2x + 12 + 7x - 3 = 180
9x + 9 = 180
9x = 180 - 7
9x = 171
x = 171/9
x = 19
m<3 = 7(19) - 3 = 133 - 3 = 130⁰
m<4 = 2(19) + 12 = 50⁰
