The second option would be parallel
20+35+30= 1 hr&25 min so she should leave at 5:20
Answer:
A. x = 5
Step-by-step explanation:
3x + 9 = 24
→ Minus 9 from both sides
3x = 15
→ Divide both sides by 3
x = 5
Answer:
x=12 ADB= 56 BDC= 54
Step-by-step explanation:
ADB and BDC are complementary, so they add up to 90 degrees. In other words ADB+BDC= 90 So I can input my knowns into the equation
(3x+10) + (4x-4) = 90
I combined like terms to give me 7x+6=90
Then I subtract 6 from both sides giving me 7x=84
Last I divide 7 on both sides. x=12
Then I input the x (12) into the equation and solve it from there
3(12)+10 and 4(12)-4
3(12)+10=56
4(12)-4=54
. . . I think. Hope this helps!
