Answer:
<em>m∠2 = 47° </em>
Step-by-step explanation:
m∠1 + m∠2 = 90°
3x + 13 + 5x - 3 = 90
8x + 10 = 90 ⇒ x = 10
<em>m∠2 = 47°</em>
B.
When you simplify the equation with the 180 surface area, you get the sqrt(30). This does not simplify any further.
When you simplify the equation with the surface area of 120, you get sqrt(20), which simplifies further to 2sqrt(5).
Then just subtract the second from the first.
Answer:
(3,2)
Step-by-step explanation:
I changed the first equation to x=y+1. Then I substituted the x in the second equation with y+1. So, I got 4(y+1)-3y=6. Then 4y+4-3y=6 turns into y=2. Then you replace y with 2 in the first equation. -x+2=-1. -x=-3 or x=3.
Well first you need to divide 4 by 12 which is 3. So 15/3=5 so she jarred in 5 days.
4/12 in simplest form is 1/3
4/12 ÷ 4/4 = 1/3
