Answer:
<u>The correct answer is D. 2x, -4y, and 8.</u>
Step-by-step explanation:
The concept of the terms of an equation is used for the monomials of each member participating in the equation. In Mathematics we distinguish between two types of terms:
1. The terms in x: when the terms are accompanied by a literal.
2. The independent terms: when the terms are constituted by numerical elements.
Answer:
Step-by-step explanation:
Let the money earned during fundraising activities =x
Since the World Issues club has decided to donate 60% of all their fundraising activities this year to Stephen Lewis Foundation.
The amount of money the foundation will receive
=60% of x
= 0.6x
In the bake sale, the club raised $72.
Therefore, the amount the foundation will receive =0.6*72=$43.20
At the end of the year, the World Issues Club mailed a cheque to the foundation for $850.
Therefore:
0.6x=850
x=850/0.6
x=$1416.67
The total amount of money the club raised is $1416.67.
Answer:
B
Step-by-step explanation:
2x+(-1.5x-2)=4
2x-1.5x-2=4
0.5x-2=4
0.5x=4+2
0.5x=6
x=6×2
x=12
y= -1.5(12)-2
y= -18-2
y= -20
Answer:
Step-by-step explanation:
Part A
Since, line shown in the graph passes through origin (0, 0), relation between number of quarts picked (Q) and amount of money paid (M) will be proportional.
M ∝ Q
M = kQ [k = proportionality constant]
k = Slope of the line =
Since, line passes through two points (1, 3.5) and (2, 7),
k = = 3.5
Therefore, M = 3.5Q
This relation states that "For each number of quarts picked, $3.5 is to be paid"
Part B
Equation that represents the proportional relation,
y = 3.5x
Or Amount of money paid = 3.5(Number of quarts picked)
