The first dryer is 25 a month, so 25 times x, or 25x.
The second is 15 per month, plus an additional $710 cost, so 15x + 710. Set these equations equal to each other to find x, the amount of months where the cost of the first dryer will equal the cost of the second dryer.
25x= 710 + 15x
-15x -15x
10x=710
x=71 months
Hope this helps
Your Welcome
First subtract 8 from both sides
leaving you with x/2 = -20
Then multiply both sides by two to get rid of the denominator
which leaves you with x = -40
Given:
Equations using properties.
To find:
The equation which use the inverse property of multiplication.
Solution:
<u>Inverse property of multiplication:</u>
<em>The product of any number and its reciprocal is always 1.</em>
Let us select the option which uses inverse property of multiplication.
Option A: 
Inverse of 
is 
. Their product is 1.
This equation uses the inverse property of multiplication.
Option B: 
Inverse of 
is 
So, it is not true equation.
Option C: 
Inverse of 
is 
.
So, it is not true equation.
Option D: ![\left[7 \cdot\left(\frac{5}{7}-\frac{4}{7}\right)\right]+8=9](https://tex.z-dn.net/?f=%5Cleft%5B7%20%5Ccdot%5Cleft%28%5Cfrac%7B5%7D%7B7%7D-%5Cfrac%7B4%7D%7B7%7D%5Cright%29%5Cright%5D%2B8%3D9)
Here also inverse property is not used.
So, it is not true equation.
Hence the equation use the inverse property of multiplication is
.
A fraction equivalent to 9/15 is 3/5
To find equivalent fractions, you have to find a a divisor that both the numerator and denominator has. Then you divide the numerator and denominator by that divisor.
Example: 9 and 15 are divisible by 3.
9 is the numerator.9 divided by 3 is 3. so the numerator of the equivalent fraction is now 3.
15 is the denominator. 15 divided by 3 is 5. the denominator is now five.
Hope this helps! :)
Answer:
The complementary angle is 72
Step-by-step explanation:
Complementary angles add to 90 degrees
Let x be the complementary angle
x+18 = 90
Subtract 18 from each side
x = 90-18
x = 72
