The sum of two numbers is 36 . The larger number is 22 more than the smaller number. What are the numbers?
Setler [38]
X + y = 36
x = y + 22

y + 22 + y = 36
2y + 22 = 36
2y = 36 - 22
2y = 14
y = 14/2
y = 7

x + y = 36
x + 7 = 36
x = 36 - 7
x = 29

so ur 2 numbers are : 7 and 29

If 111 people attend a concert and tickets for adults cost $4 while tickets for children cost $3.25 and total receipts for the c
VikaD [51]

Answer:

57 children

54 adults

Step-by-step explanation:

Let's call x the number of children admitted and call z the number of adults admitted.

Then we know that:

x + z = 111

We also know that:

3.25x + 4z = 401.25

We want to find the value of x and z. Then we solve the system of equations:

-Multiplay the first equation by -4 and add it to the second equation:

-4x - 4z = -444

3.25x + 4z = 401.25

----------------------------------

-0.75x = -42.75

x =\frac{-42.75}{-0.75}\\\\x=57

Now we substitute the value of x in the first equation and solve for the variable z

57 + z = 111

z = 111-57

z = 54

If I could get some help it would be very much appreciated
raketka [301]

Answer:

Step-by-step explanation:

A circle is 360 degrees. What we are asked in words is, "How many degrees is 40% of 360?" Let x be "how many degrees"; the word "is" means =; 40% as a decimal is .4; the word of in this context means to multiply; and 360 is just 360. Putting all that together into an equation we can solve for x:

x = .4(360) so

x = 144

Adventure movies covers 144 degrees of that circle.
