We know that AB is perpendicular to CD. (that was given)
Perpendicular angles are 90 degrees because two straight lines (180) crossed make 4 90 degree angles.
180+180=360
90*4=360 See the similarities?
7x+6= 90 degrees
Subtract 6 on both sides.
7x=84
Divide both sides by 7.
x=12
"B" is the correct answer.
I hope this helps!

Answer:
The weight of green beans in each jar is 1/16 pounds
Step-by-step explanation:
Total weight of beads = 3/4 pounds
Weight of pink beads = 1/6 × 3/4 pounds = 1/8 pounds
Weight of green beads = 3/4 - 1/8 = 5/8 pounds
Total weight of green beads in 10 jars = 5/8 pounds
Weight of green beads in each jar = 5/8 ÷ 10 = 5/8 × 1/10 = 1/16 pounds
To know which fraction is greater than another is to first look at the denominator
<u>example</u>
if u look at the denominator the one with the highest denominator is the smallest and then you look at the numerator to imagine if its closer to the denominator or farther away from the denominator.
Answer:
(-6,8)
Step-by-step explanation:
2x + 9y = 60
-9x + y = 62 --> y = 9x + 62 --> 2x + 9(9x + 62) = 60 -->
2x+ 81x + 558 = 60 -->
83x + 558 = 60 -->
83x = -498 -->
x = -6 -->
y = 9(-6) + 62 -->
y = 8
For the first one, the answer is -1 1/5
for the second one, the answer is 2.75
for the third one and fourth one,
To divide fractions take the reciprocal (invert the fraction) of the divisor and multiply the dividend. This is the quickest technique for dividing fractions. The top and bottom are being multiplied by the same number and, since that number is the reciprocal of the bottom part, the bottom becomes one
