hope this helps, i just took the quiz.
1) 1/5 (x-25) = 7
1/5x - 5 = 7
Add five to both sides
1/5x = 12
Divide both sides by 1/5
x = 60
Answer:
I can't post a graph, but I will explain how to do it.
Step-by-step explanation:
The y intercept is 3, so we know we can place a point at the coordinates (0,3). The y intercept is the point where your line crosses the y axis.
The slope is -3, which is the same as -3/1. The top number is the y axis, the bottom number of the slope is the x axis. This tells us that for every 1 space we move on the x axis, we move -3 spaces on the y axis. You should therefore have a second point located at (1,0).
You should end up with a line with a point at (0,3) and (1,0) which slopes down from left to right. Hope that helps.
To find the total amount of material Jane needs, we need to add the individual amounts. Add 2 5/8 and 1 3/4.
2 5/8 + 1 3/4
Convert these mixed numbers to improper fractions before adding. To do so, multiply the denominator by the whole number, and add the numerator. The number that results becomes the new numerator. The denominator remains the same.
2 5/8 --> 8 × 2 + 5 = 21 --> 21/8
1 3/4 --> 4 × 1 + 3 = 7 --> 7/4
We now have:
21/8 + 7/4
To add these, we must get common denominators. Multiply 7/4 by 2/2 to get a common denominator of 8.
7/4 × 2/2 = 14/8
Solve.
21/8 + 14/8 = 35/8
To convert this improper fraction to a mixed number, divide the numerator by the denominator; this becomes the whole number. The remainder goes above the denominator, and that's the new fraction.
35/8 = 4 with a remainder of 3; this goes over the denominator (8).
