Answer:
$1,080
Step-by-step explanation:
To solve, we can make a proportion
14 lessons are $210 and 72 lessons are $x
14/210=72/x
Cross multiply
14*x=210*72
14x=15120
To solve for x, we need to get x by itself. Since x is being multiplied by 14, divide both sides by 14.
14x/14=15120/14
x=1080
So, 72 lessons will cost $1,080
Answer:

Step-by-step explanation:
The computation shows that the value of the expression is 2.3.
<h3>How to illustrate the information?</h3>
It should be noted that the information given is illustrated as:
2.3(4.5-3 1/2)
This will be solved thus:
2.3(4.5-3 1/2)
2.3 ( 4.5 - 3.5)
= 2.3 (1)
= 2.3 × 1
= 2.3
Therefore, the value is 2.3

Step-by-step explanation:
a=110. x,55
y=180-(x+75)=50
w,75
b,110
x,40
y,30
the graph does not represent a function cause when you make a t chart and put all of the points on it some of the y's have the same x. to have a liniar function the x points and the y points have to be to one another accept the y points can have two of the different x points. you can also do the vertical line test to se if it is a function.
the answer is c.
