Answer:
2 and 3
Step-by-step explanation:
To simplify this expression, you will need to use the distributive property.
Multiply -2/5 by 15 = <u>- 6</u>, -2/5 by -20d = <u>8d</u>, and -2/5 by 5c = <u>-2c</u>.
you can switch these around to get -6 + 8d - 2c and -2c + 8d - 6.
Hope this helps :)
Given:
22
gallons of 16% ammonia
24%
ammonia
Find:
Number
of gallons of water to remove
Solution:
Let
n = number of gallons needed to obtain 24% ammonia
22
gallons (0.16) = n (.24)
<span>N = 14.67 gallons of water</span>
SOLUTION:
Step 1:
In this question, we are given the following:
Step 2:
The details of the solution are as follows:
What variable expression should you subtract from both sides of the equation so that you are left with no variables on the right-hand side?
The variable expression is: subtract 5x from both sides so that you are left with no variables on the right-hand side
CONCLUSION:
The final answer is:
The value of x for both angles to be vertically opposite is 27
<h3>Vertical angles</h3>
The measure of vertical angles are equal and they are angles that meet at the point of intersection of two lines.
In order to determine the value of x, we will equate both angles to have;
2x = 54
Divide both sides by 2
2x/2 = 54/2
x = 27
Hence the value of x for both angles to be vertically opposite is 27
