Answer:
x = 5
Step-by-step explanation:
We have the algebraic expression and are asked to solve for x.
To solve, we need to isolate x.
2x + 22 = 4(x + 3)
Distribute :
2x + 22 = (4(x) + 4(3))
2x + 22 = 4x + 12
Subtract 12 from both sides :
2x + 10 = 4x
4x = 2x + 10
Subtract 2x from both sides :
2x = 10
Divide 2 from both sides to get x alone :
x = 5
-38+6x evaluate the power calculate the difference
Use distance formula d=sqrt root (y2-y1)^2+(x2-x1)^2. So (-3, 4) and (1, 7). D= sqrt root ( 7-4)^2+(-3+1)^2. So now solve d= sqrt (3)^2+(-2)^2. Now d= sqrt 9+4. D= sqrt 13 or 3.60555
6p + 3n = 18
2p = n
6p + 3(2p) = 18
6p + 6p = 18
12p = 18
p = 18/12 = 1.50
2p = n
2(1.50) = n
3 = n
true statements : The equation 2n = p should be 2p = n
The actual cost of onions is $ 3 per lb
Potatoes cost $ 1.50 per lb
