For the equation to work, you have to have the same number on both sides of the equal sign

so to find ?, you can do:

13 - 2 = 12 - ? Simplify

11 = 12 - ? Subtract 12 on both sides

-1 = - ? Multiply -1 on both sides

1 = ?

Step-by-step explanation:

75 + 55x = 350

75 - 75 + 55x = 350 - 75

55x = 275

$\frac{55x}{55} = \frac{275}{55}$

x = 5

explain how to use estimation to help find the product of two decimals. give an example with both estimated and actual answer

Marrrta [24]

To find the product of a reasonable estimate of two decimal numbers, round each decimals to the nearest whole number and then perform the multiplication.

For example:

3.2 x 5.7

Estimated answer

3.2 will be rounded down to 3 and 5.7 will be rounded up to 6

⇒ 3 x 6 = 18

Actual Answer

3.2 x 5.7

=18.24

Which graph models the solution set of 50x + 150y>1500?

hodyreva [135]

Answer:

see attached diagram

Step-by-step explanation:

First, draw the dashed line 50x+150y=1500 (dashed because the inequality is without notion "or equal to"). You can do it finding x and y intercepts.

When x=0, then 150y=1500, y=10.

When y=0, then 50x=1500, x=30.

Connect points (0,10) and (30,0) to get needed dashed line.

Then determine which region (semiplane) you have to choose. Note that origin's coordinates (0,0) do not satisfy the inequality 50x + 150y>1500, because

$50\cdot 0+150\cdot 0=0$
