Answer:
Step-by-step explanation:
If its fractions, you would do 5/47
2.4=6x so isolated the variable, 2.4/6=0.4 so x=0.4
10×4,000=40,000 because all u do is add an extra zero everything you multiple something by ten
Answer:
x = 73
x = -35
Step-by-step explanation:
Here are the 8 numbers:
34, 31, 15, x, 17, 4, 20, 25
Here are the 8 numbers in ascending order with x as the greatest number:
4, 15, 17, 20, 25, 31, 34, x
x - 4 = 69
x = 73
Here are the 8 numbers in ascending order with x as the smallest number:
x, 4, 15, 17, 20, 25, 31, 34
34 - x = 69
-x = 69 - 34
-x = -35
x = -35
Answer:
x = 73
x = -35
1. A system of equations to determine the cost of a bottle of juice, is <u>12x + 2.70 = 15.78</u>.
2. From the equation, x = $1.09.
<h3>What is an equation?</h3>
An equation is a mathematical statement that shows that two values are equal.
A system of equations uses numbers and variables.
<h3>Data and Calculations:</h3>
The cost price of a bag of chips = $2.70
The total cost of snacks = $15.78
The total cost of 12-pack of juice bottles = $13.08 ($15.78 - $2.70)
Therefore, a bottle of juice = $1.09 ($13.08/12)
<h3>Equations:</h3>
Let a bottle of juice = x
Total cost of snacks = $15.78
2.70 + 12x = 15.78
or 12x + 2.70 = 15.78
12x = 13.08
x = 1.09 (13.08/12)
