Mnenie [13.5K]

Answer:

No frills = $0.25(x)

simple = $6 + $0.05(x)

set equal to each other

0.025(x) = 6 + 0.05(x)

rearrange like terms together

0.025(x) - 0.05(x) = 6

0.020(x) = 6

x =300

Simple plan will be cheaper once you use more than 300 checks

How do you solve this equation: 2/3x-5/8x=26
lbvjy [14]
First, multiply all fractions by 2.
3x-10/8x=52
Then multiply all sides by -10.
-30x + 8x = -520
-22x = -520
Divide both sides by -22.
x=23.6363

A friend asked lara to help her divide 456.3 by 100. what should lara tell her? a. move the decimal point three places to the ri
Alex73 [517]

Answer:

Step-by-step explanation:

The correct answer is D.  If we are multiplying by 10 we would move the decimal place one place to the right to show that the number is now 10 times bigger.  If we multiply by one hundred.  We are getting 100 times bigger, so we would move the decimal place 2 places to the right.

The opposite is true if we are dividing.  Instead of moving the decimal to the right to show that the number is getting bigger, we move to the left to show that the number is getting smaller.  If we are getting smaller by 10, we would move the decimal one place to the left. In this case, we are getting 100 times smaller so we move the decimal two places to the left.

X/-5=-20<br><br> A -100 or 100<br> B -4 or 4<br> C 100<br> D no solution
alexgriva [62]

Move the negative sign to the left

-x/5 = -20

Multiply both sides by 5

-x = -20 × 5

Simplify 20 × 5 to 100

-x = -100

Multiply both sides by -1

<em>x = 100</em>

<u>C. 100</u>
