The number of videos will be 3 and the number of CDs will be 2.
<h3>What is an expression?</h3>
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that Christine went shopping and bought each of her five nephews a gift, either a video costing $14.95 or a CD costing $16.88. She spent $78.61 on the gifts.
The number of the videos and CD will be calculated by forming an equation:-
14.95x + 16.88y = 78.61
From heat and trial, we put x = 3 and y = 2 then calculate.
14.95 x ( 3 ) + 16.88 x ( 2 ) = 78.61
44.85 + 33.76 = 78.61
78.61 = 78.61
Therefore, the number of videos will be 3 and the number of CDs will be 2.

they cancel out so then it becomes zero
Answer:
y=3/10x
Step-by-step explanation:
First, use the formula y2-y1/x2-x1. Pick any two points from the line to put into this formula. In this case, I would pick (0,0) and (20,6) cause I'm lazy lol. Plot these points into the formula. It would look like this 6-0/20-0. Simplify this to get 6/20. The GCM of 6 and 20 is 2 so divide 2 in each side to get 3/10. Because the y-intercept is on 0, there is no y-intercept. Therefore, the equation is y=3/10x

Answer:
7/20
Step-by-step explanation:
To add fractions, the first step is to get a common denominator
1/4 + 1/10
The common denominator is 20
1/4 *5/5 = 5/20
1/10 *2/2 = 2/20
5/20 + 2/20 = 7/20
