Find out how to get fro, -10.48 to 20. When you add .48 it makes it just $10. Add 30 more and get $20.
Answer:
2(3x+x)=50...4x=25...width is 6/25 meter and length is 18/75
Answer:
Step-by-step explanation:
<u>Let the cost of a sheet be s and cost of a blanket be b</u>
<u>From the first equation we get:</u>
<u>Substitute in the second equation</u>
- s + 4*(41 - 2s) = 80
- s + 164 - 8s = 80
- 7s = 84
- s = 12
<u>Then</u>
Answer:
x = 21°
y = 29°
Step-by-step explanation:
a) Solving for x
Note that:
(3x - 3)° and 60° are Alternate interior angles, and alternate interior angles are equal to each other, hence:
3x - 3 = 60° (Alternate interior angles)
Add 3 to both sides
3x - 3 +3 = 60 + 3
3x = 63°
x = 63°/3
x = 21°
b) Solving for y
Notes that:
(3x - 3)° and (4y + 4)° are Consecutive interior angles and the sum consecutive interior angles is 180°
3x - 3 + 4y + 4 = 180°
3x + 4y - 3 + 4 = 180°
3x + 4y + 1 = 180°
Note that x = 21
Hence
3(21) + 4y + 1 = 180°
63 + 1 + 4y = 180°
64 + 4y = 180°
Subtract 64 from both sides
64 - 64 + 4y = 180° - 64
4y = 116°
y = 116/4
y => 29°
