Answer:
Within 52 weeks, the amount of water in the two fish tanks will be the same.
Step-by-step explanation:
First, let's make the two equations equal to each other by placing an equal sign.
832 - 5x = 1040 - 9x
Now, that they are equal to each other, we can solve for x.
Okay, so we can move -5x to the other side by adding both sides with 5x.
832 = 1040 - 4x
Then, subtract 1040 from both sides to move it to the other side.
832 - 1040 = -208
-208 = -4x
Lastly, divide both sides by -4 to get the value of x.
-208/-4 = 52
x = 52
Answer:
m∠A = 100
m∠C = 50
Step-by-step explanation:
let 'x' = m∠A
let 'x/2' = m∠C
x + x/2 + 30 = 180
3/2x = 150
x = 150(2) / 3
x = 300/3
x = 100
m∠A = 100°
m∠C = 100/2 or 50°
Answer:
x = 0; x = 5
Step-by-step explanation:
2x² = 10x
2x² - 10x = 0
2x(x - 5) = 0
x = 0; x = 5
Answer:
15.9
Step-by-step explanation:
Formula:
a² + b² = c²
6² + x² = 17²
36 + x² = 289
x² = 253
x = 15.91
