Answer: Yes, the answer is 40 quarters.
Step-by-step explanation:
1. You need to remember that 4 quarters make a dollar.
2. Keeping this on mind, you can make a Rule of three, as following: If there are 4 quarters in 1 dollar, how many quarters are in 10 dollars?
Then:
4 quarters-------1 dollar
---10 dollars
3. Therefore, there are 40 quarters in one roll.
Answer: C $1.51
To solve this, start with a proportion. Put the CPI numbers on the left and the apple juice prices on the right.
You will have:
82.4/130.7 = 0.95/x
Cross multiply to solve and you will get the price of the juice is $1.51.
Answer:
a. has one solution
b. infinite solution
Step-by-step explanation:
a.
2(x - 1) + 6 = 4x - 22
2x - 2 + 6 = 4x - 22
2x - 4x = 2 - 6 - 22
-2x = -26
x = 26/2
x = 13
b.
6(2x + 1) – 2 = 12x + 4
12x + 6 - 2 = 12x + 4
12x - 12x = 4 + 2 - 6
0 = 0
The slope-intercept form:
m - slope
b - y-intercept → (0, b)
We have the points (-4, -6) and (2, 6). Substitute:
Put the coordinates of the point (2, 6) to the equation of a line:
<h3>Answer: y = 2x + 2</h3>
Equation you asked: 4x +4y = 20, Rewritten equation: -1x + 5
hope this helps.
