The equations used to find the measure of each angle in degrees is x + y = 90 and x = 6y - 1
The two complementary angles are 77 degrees and 13 degrees
<em><u>Solution:</u></em>
Given that two angles are complementary angles
Complementary angles are two angles whose sum is 90 degrees
Let one of the angle be "x" and the other angle be "y"
Therefore,
x + y = 90 ------ eqn 1
Also given that,
One angle is one less than six times the measure of another
one angle = six times the other angle - 1
x = 6y - 1 ------ eqn 2
Substitute eqn 2 in eqn 1
6y - 1 + y = 90
Thus the above equation is used to find the measure of each angle in degrees
Solve the above equation
6y + y - 1 = 90
7y - 1 = 90
7y = 91
y = 13
Substitute y = 13 in eqn 2
x = 6(13) - 1
x = 78 - 1
x = 77
Thus the two complementary angles are 77 degrees and 13 degrees
Answer: To add area you have to do Multiplication to get what you want so
15 * 2 1/2 = 37.5 or 32 1/2 depending if they want decimal or fraction though in this case it can be either so put either one

Step-by-step explanation:
Answer:
1. Write all the equations in standard form, leaving out decimals or fractions.
2. Select the variables to be eliminated; And then you take two of these equations, and you eliminate the variables.
3. Select a different set of two equations and eliminate the same variables as in step 2.
4. Solve two equations containing two variables from steps 2 and 3.
5. Substitute the answer to step 4 into any equation that contains the remaining variables.
6. Check the solution with three original equations.
Answer:
Step-by-step explanation:
Using the formula for calculating speed;
Speed = Distance/Time
Given
Speed = 3/24 miles per 3 hours
Required
Distance travelled in an hour
3/24 miles = 3 hours
x = 1 hour
Cross multiply;
3 * x = 3/24 * 1
3x = 3/24
Cross multiply;
3x * 24 = 3
72x = 3
x = 3/72
x = 1/24
Hence the distance travelled each hour is 1/24 miles
