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>
You want to have your x alone so you would get rid of the 3. to do that you must do the opposite of what it's saying which it is multiplying so you would divide 3 and do it on both sides. so 3/3 cancels eachother out and now you have to divide 29 and 3 and that is what x equals
M=4b
m=27+b
subsitute
4b=27+b
minus b
3b=27
divide 3
b=9
sub back
4b=m
4(9)=m
36=m
michel=36 and brandon is 9
Answer:
Step-by-step explanation:
Find the width as below
- l² + w² + h² = d², where l- length, w- width, h- height, d- the distance between top and bottom corners
Substitute the values and solve for w
- 4² + w² + 12² = 13²
- w² + 160 = 169
- w² = 9
- w = 3 feet
Now find the volume
- V = lwh
- V = 4*3*12 = 144 ft³
