from the equal angles it is an isosceles triangle, AB = AC.
4x + 1 = 2x + 23
4x - 2x = 23 - 1
2x = 22
x = 22 : 2
x = 11
----------------------
4 * 11 + 1 = 2 * 11 + 23
45 = 45
--------------
now we find BC
3x - 8
3 * 11 - 8 =
25 (is the value of BC)
Answer:
I think it is c
Step-by-step explanation:
Given:
8000 homes
color flyers : $0.08 each
black and white flyers : $0.05 each
budget of $500
c + b = 8,000
0.08c + 0.05b = 500
c = 8,000 - b
0.08(8,000 - b) + 0.05b = 500
640 - 0.08b + 0.05b = 500
-0.03b = 500 - 640
-0.03b = -140
b = -140 / -0.03
b = 4,667 black and white flyers
c = 8,000 - b
c = 8,000 - 4,667
c = 3,333 colored flyers
0.08(c) + 0.05(b) = 500
0.08(3,333) + 0.05(4,667) = 500
266.64 + 233.35 = 500
499.99 = 500
500 = 500
5 feet / 8 feet = flagpole / 24 feet
24 * 5 / 8 = flagpole height
120 / 8 = flagpole height
flagpole height = 15 feet
The time taken by a group of 8 people working half the rate of the first group is 7.5 hours.
<h3>What is a fraction?</h3>
Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
We have:
A Group of 5 people can do a piece of work in 6hrs.
5 people, at a rate of 1, and the time taken is 6 hours
Work done is 30
8 people, at a rate of 1/2, and the time taken is x hours
8(1/2)x = 30
x = 60/8 = 7.5 hours
Thus, the time taken by a group of 8 people working half the rate of the first group is 7.5 hours.
