−3=8x−4y
,Step 1: Flip the equation.
,8x−4y=−3
,Step 2: Add -8x to both sides.
,8x−4y+−8x=−3+−8x
,−4y=−8x−3
,Step 3: Divide both sides by -4.
,−4y/−4
,=−8x−3/−4
,Answer:
y=2x+3/4
It usually works to use the formula for the area of a trapezoid.
A = (1/2)×(b₁ +b₂)×h
where b₁ and b₂ are the lengths of the parallel bases, and h is the height (the perpendicular distance between the bases)
_____
This is one of several area formulas it pays to memorize.
Answer:
2 miles
Step-by-step explanation:
Peter takes 7 minutes and 30 seconds per mile.
7 times 2 is 14 minutes.
30 seconds times 2 is 1 minute.
If you add these 2 values together you get 15 minutes.
So we need to times the miles by 2 to get 2 miles.
I hope this helps, have a lovely day.
Step-by-step explanation:
when scaling all dimensions must be multiplied by the same factor.
64 was first scaled ft to in, and then by 2.8/64.
now we need to do the same for the width :
80 × 2.8/64 = 3.5 in
Answer:
Lavania observed 39 fruit flies after 6 days of observation
Step-by-step explanation:
Let x be the number of fruit flies on the first day of Lavania's study.
After 6 days she had nine more than five times as many fruit flies as when she began the study.
Five times as many fruit flies as when she began the study = 5x
Nine more than five times as many fruit flies as when she began the study=5x+9
The expression to find the population of fruit flies Lavania observed after 6 days is 5x+9
If she observes 20 fruit flies on the first day of the study, then x=6, then
