Answer:
x=120°
Step-by-step explanation:
X+X+1/2X+1/2X=360
combine all like variables
X+X=2X
1/2X+1/2X=X
2X+X=3X
3X=360
isolate x by dividing both sides by 3
360÷3=120
X=120

Mrs. Blake needs to hire a babysitter. Kelsey charges $6 per hour plus a $5 fee. Lauren charges $4 per hour, plus a $10 fee. Mrs. Blake set up this equation to figure out for what amount of time both babysitters charge the same.
6h + 5 = 4h + 10
What is the correct sequence of steps to solve Mrs. Blake’s equation?
A. Subtract 6h from both sides. Subtract 5 from both sides. Divide each side by –2.
B. Subtract 4h from both sides. Subtract 5 from both sides. Divide each side by 2.
C. Subtract 4h from both sides. Add 5 to both sides. Divide each side by 2.
D. Subtract 4h from both sides. Subtract 5 from both sides. Divide each side by 6.

Step-by-step explanation:
The y-intercept is -10, as in, the line on the y-axis is at -10
The slope is 5, as in, the line is moving up 5 and right 1. So it should be 5/1x but you don't need the 1. You could use it, but you don't need to. Here's what it would look like if you did use it:

1. How much simple interest is earned on $3,000 in 9 years at an interest rate of
4.5%?
Can anyone help please? This is due tomorrow and I don’t understand this
Answers
Answer:
I = $1,215
Step-by-step explanation:
Principal (P ) = $3,000
interest rate (R ) = 4.5% or 0.045
time (in years) ( t )= 9
Use the simple interest formula:
I = P × r × t
I = $3,000 × 0.045 × 9
I = $1,215
Therefore, the simple interest earned on a $3,000 investment after 9 years is $1,215.

Write a quadratic function [tex]f[/tex] whose only zero is 12.
Answers
Answer:
f(x) = (x - 12)²Step-by-step explanation:
If a quadratic function has only one zero, then it has multiplicity of two as it is a second degree polynomial and should have two roots. Since one root is a real number, the second root is also a real number being same as the first number.
The function could be:
f(x) = (x - 12)²We know the rule for single zero of quadratic equations

The amount of calories in a cheeseburger increases by 1.42 when there are zero grams of fat.
The calorie amount estimated by this model is 121 if there is one gram of fat.
Answers
Using linear function concepts, it is found that the correct option is:
The amount of calories in a cheeseburger increases by 1.42 for every one gram of fat. The calorie amount estimated by this model is 121 if there are zero grams of fat.
A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which represents by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.In this problem:
The explanatory variable fat is the input.The response variable calories is the output.The equation is:
[tex]y = 121 + 1.42x[/tex]
The slope is of 1.42, which means that the amount of calories increases by 1.42 when the amount of fat increases by 1 gram.The y-intercept is of 121, which means that if there are 0 grams of fat, there will be 121 calories.Thus, the correct option is:
The amount of calories in a cheeseburger increases by 1.42 for every one gram of fat. The calorie amount estimated by this model is 121 if there are zero grams of fat.
