Answer:
s=40
Step-by-step explanation:
Combine s and 1/2.
150−s/2=120+1/4s
Combine 1/4and s.
150−s/2=120+s/4
Move all terms containing s to the left side of the equation.
150−3s/4=120
Move all terms not containing s to the right side of the equation.
−3s/4=−30
Multiply both sides of the equation by −4/3.
−4/3 x (−3s/4)=−4/3 x−30 => S=40
Answer:
31°
3
108°
Step-by-step explanation:
The measure of angle ADB is congruent to the measure of angle CBD, so it is equal to 31°.
4x = 12
divide by 4 on both sides and you are left with x=3
angle A is congruent to angle C, so it is equal to 108°.
Hope this helps!
Answer:
Step-by-step explanation:
<u>Given</u>
- A costs 5$
- B costs $0.25
- C costs $0.05
- A + B + C = 100
- 5A + 0.25B + 0.05C = 100 ⇒ 100A + 5B + C = 2000
<u>Subtract the first equation from the second:</u>
<u>We have a restriction in numbers:</u>
<u>Since 4B can be max 400, we get 99A > 1500 and 99A < 1900 so:</u>
and
A can be 16 or 18 as it should be even number to get B the whole number.
<u>If A = 16:</u>
- 99*16 + 4B = 1900
- 4B = 1900 - 1584
- 4B = 316
- B = 316/4 = 79
<u>If A = 18:</u>
- 99*18 + 4B = 1900
- 4B = 1900 - 1782
- 4B = 118
- B = 118/4 = 29.5, discarded as decimal
<u>So we get:</u>
- A = 16, B = 79 and C = 100 - (16 + 79) = 5
<u>Let's proof the numbers:</u>
- 16*5 + 79*0.25 + 5*0.05 = 100, confirmed
Answer:
