I think so because she started at 2 1/4 then hiked to 4 3/8. That is roughly 2 miles and then from there she joked all the way back to 11/2
PEMDAS
-3(-2)^2-12(-2)+3
-3(4)-12(-2)+3
-12-12(-2)+3
-12+24+3
12+3
=15
.63-(-9.85)= 10.48 I hope this helped. :)
Answer:
Step-by-step explanation:
3(2 + 3 + 4)^2
3(9)^2 = 3(81) = 243
Answer:
Step-by-step explanation:
∠ABD = 100
∠ABC + ∠CBD = ∠ABD
4x + 2 + 3x - 7 = 100
4x + 3x +<u>2 -7 </u>= 100 {Combine like terms}
7x <u> -5 </u> = 100
Add 5 to both sides
7x = 100 +5
7x = 105
Divide both sides by 7
x = 105/7
x = 15
∠CBD = 3x - 7
= 3*15 - 7
= 45 - 7
∠CBD = 48
