Answer: Your answer is 627
Step-by-step explanation: If you add 220 to 627, it becomes 847. You can find out by taking away 220 from 847 because the answer would be the same anyways.
2 to the 13th power = 8192
8192 divided by 8 = 1024
4x - 5y = -15
y = -3x + 22
Plug in your y= equation into the y variable in the other equation
4x - 5 (y) = -15
^^
y = (-3x + 22) = -15
4x - 5 (-3x + 22) = -15
Distribute
4x + 15x - 110 = -15
Combine like terms and add 110 over to -15
19x = 95
Then, divide the whole equation by 19
x = 5
Then, plug in your x into your y= equation
y = -3 (5) + 22
y = -15 + 22
y = 7
<em><u>x = 5</u></em>
<em><u>y = 7</u></em>
<em><u>(5, 7)</u></em>
Answer:
The deep of the water would be 20 cm
Step-by-step explanation:
step 1
Find the volume of the water
The volume of the water is equal to

we have

substitute


step 2
Find the deep of the water, if the tank is returned to its horizontal position
(resting on its 60 cm × 100 cm base)
Now we have


substitute the given values

solve for H


therefore
The deep of the water would be 20 cm
Answer:
1/4 or 0.25
Step-by-step explanation:
- 3.2(4m + 10) – (-7.2m) = 37
- 12.8m+32+7.2m=37
- 20m= 37-32
- 20m=5
- m=5/20= 1/4 or 0.25
