Helen spent $145 for shoes. This was $55 more than twice what she spent for a bag. How much was the bag?
marin [14]

Answer:

45 DOLLARS

Step-by-step explanation:

For these kind of problems, write an equation to figure out the answer.

55 + 2x = 145

x represents the bag cost

145 is the shoe cost

Take out the constant, which is 55, from both sides. A constant is a useful term you should learn.

The result is: 2x = 90

Divide 2x by 2, to get x, which is the bag cost, by itself.

Result: x= 45

Since x is the bag cost, the bag costs 45 dollars

Answer:

  B.  Up 1 and 2 to the left

Step-by-step explanation:

The second graph (blue) is up 1 and 2 left of the first graph (red).

__

You can compare the given equations to the form ...

  y = a(x -h)^2 +k

For the first graph, we have (h, k) = (6, -1).

For the second graph, we have (h, k) = (4, 0).

Then the amount added to the first to make the second is ..

  (4, 0) -(6, -1) = (-2, 1) . . . . . . a translation 2 left and 1 up

X+6/2 + 5−4x/3 − 8−x/6 =0
natka813 [3]

Answer:

x = 0

Step-by-step explanation:

x+\frac{6}{2}+5-4\cdot \frac{x}{3}-8-\frac{x}{6}=0

x+3+5-4\cdot \frac{x}{3}-8-\frac{x}{6}=0

x+3+5-\frac{4x}{3}-8-\frac{x}{6}=0

x-\frac{4x}{3}-\frac{x}{6}+3+5-8=0

x-\frac{4x}{3}-\frac{x}{6}=0

x\cdot \:6-\frac{4x}{3}\cdot \:6-\frac{x}{6}\cdot \:6=0\cdot \:6

6x-8x-x=0

-3x=0

\frac{-3x}{-3}=\frac{0}{-3}

x=0
