First off, let's keep in mind that perpendicular lines have negative reciprocal slopes, hmmm so what's the slope of y = 2x + 5?
well, notice, that equation is in slope-intercept form, thus

.

so, we're really looking for the equation of a line whose slope is -1/2 and runs through 1,4.
Answer is 36.
20 * 80/100 = 16
20+16=36
8ft is the length of the rope on the outside of the tent. I hope its right!
Answer:
D.) 1 3/5
Step-by-step explanation:
You need 1/5 cups of flour 8 times so you need to multiply 1/5 by 8.
1/5 × 8 = 8/5
Then simplify.
8/5 = 5/5 + 3/5 = 1 3/5
Answer:
The answer is 3.2 E 3 or 3.2 x 10^3
You move back 3 spaces which is 3.2, since you moved back 3 spaces, you put 3 as the power/exponet.
To be more satisfied, 3.2 is your base number, it is the big number Below the power/exponent. The power/exponent is 3, you moved 3 spaces and you moved to the left, so it is represented as a positive power/exponent.
Hope this helps.
