1. (77+x)/2=84
2. Harold needs at least a 91
Work:
first, you multiply both sides by 2; 77+x=168
then you subtract 77 from both sides; x=91
then you plug it back in to check; (77+91)/2=84 ; 168/2=84 ; 84=84
Use the tangent ratio for the angle: tan 34 = b/16. Now multiply both sides by 16 to get 16 tan 34 = b or b = 10.79. Choice A above
Answer:
483.75 is needed
Step-by-step explanation:
161.25 * 4 = 645.00
645.00 - 161.25 =
Answer:
bbbbbb
Step-by-step explanation:
:)
17 = 3(4x - 5)
<em><u>Distributive property.</u></em>
17 = 12x - 15
<em><u>Add 15 to both sides.</u></em>
32 = 12x
<em><u>Divide both sides by 12.</u></em>
x = 2.67. (This is your answer.)
