The system of equations to find the cost of one adult ticket, a, and the cost of one child ticket, c are Roy's; 6a+2c=66 Elisa's 5a+4c=62.
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Let's consider adults tickets be a and child tickets be c
so
Roy's purchase
6a+2c=66------1
Elisa's purchase
5a+4c=62-------2
Hence, the system of equations
6a+2c=66------1
5a+4c=62-------2
solving simultaneously
6a+2c=66
5a+4c=62
Also,
12a+4c=132
-5a+4c=62
7a=70
a=$10
put a=70 in 1
6(10)+2c=66
60+2c=66
2c=66-60
2c=6
c=$3

Use the property that angles sum up to 360 degrees.
Also use property that <M = <R and <A = <P.
That gives the following equation:
m<R + m<A + m<M + m<P = 360
6x+5 + 9x+25 + 6x+5 + 9x+25 = 360
30x + 60 = 360
x = 10
Answer:
x = 10
m<M = 6x+5 = 65 degrees
Answer:
24.5
Step-by-step explanation:
2p/7 = 7
cross multiply
2p = 49
p = 24.9
So we want to find how much more space the logo took up.
So just subtract the location info from the logo space.
2/7 - 1/10
To subtract, you just want to find a common denominator. In this case it would be 70.
2/7 * 10/10 - 1/10 * 7/7
20/70 - 7/70
Then just subtract.
13/70
So that's the fraction. For the percent, just divide.
13/70 = 0.186 ish
Or, 18.6% ish
