Answer:
Step-by-step explanation:
<u>Simplify, rationalize the denominator</u>
- √2/(3 + √5) =
- √2(3 - √5)/(3 + √5) (3 - √5) =
- (3√2 - √10)/(3² - 5) =
- (3√2 - √10)/4
Answer:
0.5, 0.15, 0.115, 0.005
Step-by-step explanation:
A number can be written from the greatest to the and the lowest to the highest when given a series of number. This series of number can be in mixed fraction forms, improper fraction or decimal. When a number is said to be written from the greatest to the lowest, it is called descending order but from the lowest to the greatest it is called ascending order.
From the list of the series of the decimal numbers given, writing the numbers in order from the greatest to the least number will choose the form:
0.5, 0.15, 0.115, 0.005
Answer:
The cost of 1 cupcake = $3.75.
Step-by-step explanation:
Let the cost of one cupcake = $ x.00
Now, the money spent by Cherie on 2 cupcakes = 2 ($x.00) = $2x
Also, the money spent by Sonya on 4 cupcakes = 4 ($x.00) = $4x
Now, according to the question:
$2x + $12.50 = $4x + $5.00
or, 2x + 12.50 = 4x + 5
⇒ 4x - 2x = 12.50 - 5
or, 2x = 7.50
or, x = 7.50/2 = 3.75
or, x = $3.75
Hence, the cost of 1 cupcake = $3.75.
5x-3=27 +3
5x=30 divide by 5
x= 6
Use distributive property
3(x + 2) = 2(2x + 7)
(3)(x) + (3)(2) = (2)(2x) + (2)(7)
3x + 6 = 4x + 14 |subtract 6 from both sides
3x = 4x + 8 |subtract 4x from both sides
-x = 8 |change the signs
<h3>x = -8</h3>
