Answer:
What is the answer choices
You take how many shirts she sold and then multiply it by the cost of one shirt.
Therefore, you do 39 shirts * $16.50, which is equal to $643.50 in revenue :)
Answer: x ≥ 40
Step-by-step explanation:
Hi, to answer this question and write the inequality we have to analyze the information given:
Each afternoon at least 40 people buy coffee in a coffee shop
In Math, at least means more or equal (≥).
So, if X represents the number of people who buy coffee in an afternoon, the inequality is (Mathematically speaking)
:
X ≥ 40

I like point point form because it doesn't fail in the no slope case. The line through (a,b) and (c,d) is
(c-a)(y-b) = (d-b)(x-a)
Point slope form is almost the same,

1. (a,b)=(4,0),(c,d)=(-2,1)
y - 0 = (1 - 0)/(-2 - 4) (x - 4)
Answer: y = (-1/6)(x-4)
2.
y - -2 = (3 - -2)/(5 - -3) (x - -3)
Answer: y + 2 = (5/8) (x+3)
3.
y - 1 = (4 - 1)/(3 - -5) (x - -5)
Answer: y - 1 = (3/8) (x+5)
Answer:
68.6
Step-by-step explanation:
Given the initial ratio of 24 points out of 35 possible points, you can set up a proportion (equivalent ratios) to find the expected number of points math students would ear on a test of 100 possible points:

Where 'x' is the number of points earned on the 100 point test.
Cross-multiply: 35x = 24(100) or 35x = 2400
Divide both sides by 35: 35x/35 = 2400/35
Solve for x: x = 68.6
