6x+3=18
subtract 3 from both sides
6x=15
divide both sides by 6
x=2.5
5(4x-5)=155
distribute the 5
20x-25=155
add 25 to both sides
20x=180
divide both sides by 20
x=9
Answer:
See below ~
Step-by-step explanation:
<u>A.</u>
- m∠5 = m∠10 (alternate angles)
- m∠10 = 69°
<u>B.</u>
- ∠4 + ∠14 = 180° (∠14 is equal to ∠8 as they are corresponding, and ∠8 is supplementary to ∠4)
- ∠14 = 180° - 114°
- ∠14 = 66°
<u>C.</u>
- ∠5 = ∠12 (as ∠10 = ∠12 by alternate interior angles, and ∠10 = ∠5 as alternate angles)
- ∠12 = 86°
Answer:
3/20=6/40=15/100
Step-by-step explanation:
Multiply 3 by 2 to figure out the numerator for /40 and multiply 20 by 5 to figure out the denominator of 15/

Answer:
9 cm
Step-by-step explanation:
The volume is given by the formula ...
V = LWH
Filling in the given numbers, you have ...
144 cm^3 = (4 cm)(4 cm)H
H = (144 cm^3)/(16 cm^2) = 9 cm
The height of the prism is 9 cm.
