Step-by-step explanation:
Answer:
Per child admission costs $8.5
Per Adult admission costs $13.5
Step-by-step explanation:
Let x be the amount of admission per child and y be the amount of admission per adult
For Tom's party:
13x+2y=137.50 (Equation 1)
For Lisa's Party:
9x+2y=105.50 (Equation 2)
Using Elimination Method:
Add Equation 1 & 2
13x+2y=137.50
9x+2y=105.50
- - = - (Change of Signs)
---------------------------------
4x+0y=34.00
x=34/4
x=8.5
Putting the value of x in Equation 2
13(8.5)+2y=137.50
110.5+2y=137.50
2y=137.50-110.50
2y=27
y=27/2
y=13.5
Answer:
×=1
Step-by-step explanation:
the equation you must use to solve this is, x=1/7×7
first use order of operations to multiply 1/7×7 you will do so by placing a 1 below the 7 to make it a fraction so that you can multiply the two numbers so the new equation would look like this, x=1/7×7/1, now solve. once you do so your solution should look like this, 7/7, which equals 1 when simplified.
