Answer:
Step-by-step explanation:
<u>The line with points (1,2) and (-1,-8). Work out its equation.</u>
<u>The slope is:</u>
- m = (-8 - 2)/(-1 - 1) = -10/-2 = 5
<u>To find the y intercept, substitute x and y-xoordinates of point (1,2):</u>
- 2 = 5(1) + b
- b = 2 - 5
- b = -3
<u>The line is:</u>
<u>Point (x, 17), substitute y-coordinate and solve for x</u>
- 17 = 5x - 3
- 5x = 17 + 3
- 5x = 20
- x = 20/5
- x = 4
The second one would be 4 inches.
Answer:20
Step-by-step explanation:
3.1 *4.2=13.02 12.4*21=260.4 260.4/13.02=20
Answer:
the value of c = 32.13
Step-by-step explanation:
all you had to do was take one of the options and divide it by 2.1 and you'll know you have to right answer when it equals 15.3 but just remember if you are dividing by a smaller number the numerator has to be a bigger number to be able to equal whatever is on the other side of the equals symbol.
sorry I'm bad at explaining but I hope this helps
1.5 cleaner / 12 cups of water
or
1.5 cleaner : 12 cups of water
to reduce this ratio of 1.5:12, we need to divide both by the same number
1.5 divided by 1.5 is 1
12 divided by 1.5 is 8
So the ratio of cleaner to water is 1:8 in its simplest form or 1 part cleaner to 8 parts water.
Hope this helps!! :)
