A) (3x+30)+(x-5)+35=180
4x+60=180
4x=120
x=30
b) A=x-5
A=25
B=3x+30
B=120
Answer:
15*3*2
15*1*6
45*2*1
10*3*3
6*5*3
Step-by-step explanation:
Volume=Lenth *Width*Height divieded by 3
The answer is 78 because when you add all the numbers it equals 780 and you need to divide the end sum by the amount of numbers added to get it. So in the end there were 10 numbers added to equal 780 so 780\10 equals 78
11x2 would be your answer.
Equation 1: y = -2x + 1
Equation 2: y = 2x - 3
Since both equations already have y isolated, we are able to simply set the right side of both equations equal to each other. Since we know that the value of y must be the same, we can do this.
-2x + 1 = 2x - 3
1 = 4x - 3
4 = 4x
x = 1
Then, we need to plug our value of x back into either of the original two equations and solve for y. I will be plugging x back into equation 2 above.
y = 2x - 3
y = 2(1) - 3
y = 2 - 3
y = -1
Hope this helps!! :)
