Answer:
x = 30
Step-by-step explanation:
The sum of the 3 interior angles of a triangle = 180°, hence
x + x + 10 + 3x + 20 = 180
5x + 30 = 180 ( subtract 30 from both sides )
5x = 150 ( divide both sides by 5 )
x = 30
She will earn 2064 dollars because 12*5=60, 14*8=112, 112=60=172, 172 *12 equals $2,064.
She should buy at the second store due to the fact that you are getting 6 mora for the same price (if you were to buy 30$ worth from the first one)
Answer:
9 child tickets and 17 adult tickets were sold.
Step-by-step explanation:
Let the number of adult tickets sold be
and the number of child tickets be .
The theater sold a total number of 26 tickets.
This means that: .....eqn1
The theater made a total sale od $194.
This implies that:
...eqn2
We make the subject in equation 1: ...eqn3
Substitute equation (3) into equation (2)
Expand to get:
Put c=9 into equation (3) to get:
Therefore 9 child tickets and 17 adult tickets were sold.
<span>The number that goes into both of these is 22 and 22 will go into 2, 11 times so that becomes 11/22 instead of ½ and then 7/11 becomes 14/22. What you do is take the common denominator and since that is 22 you say how many time will 2 go into 22 and it is 11 so multiply 11*1 which is 11 then do the same with the 7/11 since it is 22 it goes in 2x so 2*7 is 14 so if you have to add the two then it is 11/22+14/22= 25/22 which would be reduced to 1 and 3/22
