Answer: Four adults
Step-by-step explanation: 4 x 35 = 140. There are no children, so you can just ignore 20y (I hope this helps!)
If no children will go to the amusement park then a total of 4 adults can go to the amusement park for $140. Hence, option C is correct.
What is an equation?Equations are logical assertions in mathematics that have two algebraic expressions on either side of an equals (=) sign. The expression on the left and the expression on the right is shown to be equal in reference to one another. LHS = RHS (left hand side = right hand side) appears in all mathematical equations.
You can solve equations to determine an unknown variable's value, which corresponds to an unknown quantity. It is not an equation if there is no "equal to" sign in the statement.
The given equation is :
35x + 20y = 140
Cost of adults to go to the amusement park, (x) = $35 and,
Cost of children going to the amusement park, (y) = $20.
If no children are going to the amusement park, then the number of adults who can go to the park is :
35x + 20(0) = 140
35x = 140
x = 140/35
x = 4.
Hence, this concludes that option C is correct.

Step-by-step explanation:
The entry ticket to a local football game costs $12 for an adult and $8 for a child. A group of 100 people paid an entry fee of $1,056. How many adults and how many children were there in this group? Drag the correct value to the appropriate box.
Step-by-step explanation:
let x be the number of adults and y number of childrens
so we have. x+y=100 people
and. 12*x+8*y=1056 dollars
x=100-y
replace 100-y to the second equation
12*(100-y)+8y=1056
1200-12y+8y=1056
1200-4y=1055
1200-1056=4y
144=4y
y=144/4=36
so x=100-y=100-36=64
so in this group were 64 adults and 36 childrens
In this group were 64 adults and 36 children.
What is system of equation ?In mathematics, a system of linear equations (or linear system) is a collection of one or more linear equations involving the same variables.
let x be the number of adults and y number of children
so we have. x + y = 100 people
and. 12 × x + 8 × y = 1056 dollars
x=100 - y
replace 100 - y to the second equation
12 × (100 - y) + 8y = 1056
1200 - 12y + 8y = 1056
1200 - 4y = 1055
1200 - 1056 = 4y
144 = 4y
y = 144/4 = 36
so x = 100 - y = 100 - 36 = 64
Hence, in this group were 64 adults and 36 children.

Write the expression to represent the words.
Answer:
1. 7x
2. x+15
3. 18/x
Step-by-step explanation:
Assume the number is x because we don’t know what it is.
1. Product means multiplication so x * 7 equals 7x.
2. More means addition so x+15.
3. This one is easy. 18 divided by x = 18/x

12x + 8y = 24 Convert from standard form to slope-intercept form.
The required equation is y = -(3/2)x + 3 in slope-intercept form.
What is the standard form of linear equations?A linear equation is written in the standard form as Ax + By = C, where A, B, and C are integers and x and y are variables.
For example, 8x + 2y = 7 is the standard form of a linear equation in two variables.
The equation is given in the question, as follows:
12x + 8y = 24
Isolate the variable of y for the above equation,
8y = - 12x + 24
Divided both sides by 8 into the equation,
y = - (12x)/8 + (24)/8
y = -(3/2)x + 3
This equation is in slope-intercept form.

Stacy wants to go on a vacation that will cost her at least $1540. She has $1825 saved but has
$65 deducted every week from her paycheck to pay for her insurance. At most, how many
weeks can she have these deductions made in order to afford her vacation
Answer:
4 weeks
Step-by-step explanation:
First,, we should subtract the vacation price from her savings to get the base. That is 1835-1540=295. Then we can do 295/65,, and then we get 4 7/13. So,, she can only afford 4 weeks of these deductions in order to have enough money for her vacation.

Julio says, "If you subtract 17 from my number and multiply the difference by -5, the result is
- 70." What is Julio's number?
Answer:
Julio's number is 31.
Step-by-step explanation:
Okay, so -70 divided by -5 is 14.
14 plus 17 equals 31.
If you subtract 17 from 31, you get 14.
Then, if you multiply 14 times -5, you get -70.

Two buses are traveling to a state park. One bus leaves the terminal at 4:00 pm, and travels at 40 miles per hour. The second bus
leaves the terminal at 5:00 p.m. and travels at 60 miles per hour.
At what time does the second bus catch up with the first bus?
Answer:
Step-by-step explanation:
When the second bus catches up to the first bus, this means that the distance they have travelled is equal.
So for bus 1, you know it travels at 40 miles per hour.
4pm = 0 miles
5pm = 40 miles
6 pm = 80 miles
7pm = 120 miles
For bus 2, you know it travels at 60 miles per hour
5pm = 0 miles
6pm = 60 miles
7pm = 120 miles.
So you can see that at 7pm, they will both have travelled 120 miles.
How much carpet would you need in square feet to cover a floor with dimensions of 12 feet by 15 feet?
Answer:8
Step-by-step explanation:
Area = Length x Width.
simple room measurement
Measure the length using the distance from one wall to the opposite wall.
Measure the width from wall to wall.
Add 2 to 4 inches to each side. This accounts for waste, doors and slanting walls. It’s easy to cut a little off for a perfect fit, but it’s impossible to add without creating unsightly seams.
Multiply the length times the width or enter those into the calculator above. This is your total square footage for that room.
Repeat this process for each room.

Step-by-step explanation:
Can anyone help with this?
Answer:
8
Step-by-step explanation:
In order to find the length and width necessary to find area, we need to look at the chart. By exmaining, we can see that the length is two units from top-to-bottom. We can also see that the width is 4 units from left-to-right. We can now multiply 4 times 2 to get our answer of 8.
Answer:
B. 8.0
Step-by-step explanation:
To figure out the area you just do length times width, and you find the two by counting the amount of squares they take up. The length is two, and the width is 4; therefore the area is 8
