Answer:
x=4-3y
Step-by-step explanation:
8-(6+2)+4 is how you use those numbers to equal 4
Since 1A claims that the diagram is of a square, you can easily find the perimeter by multiplying just one side by 4, because the definition of a square says that all of its four sides are equal in length.
Take the left side, x and 4, and add them together, because both of these lengths add up to form the side of the square. You have found one side of the square, x + 4. Now multiply this side by 4 for the perimeter.
Perimeter is the length all around the figure, and since a square has 4 sides you would multiply one side by 4 to find the perimeter.
4(x + 4) is your expression for the perimeter of the square. You could probably solve 1B and 1C by substituting in 3 and 5 for x in the equation I've given you :)
Answer: 188 children and 200 adults were admitted.
Step-by-step explanation:
Let x represent the number of children that were admitted that day.
Let y represent the number of adults that were admitted that day.
On a certain day, 388 people entered the park. It means that
x + y = 388
The admission fee at the amusement park is $2.00 for children and $6.80 for adults. The admission fees collected that day totaled $1736. It means that
2x + 6.8y = 1736- - - - - - - - - - - 1
Substituting x = 388 - y into equation 1, it becomes
2(388 - y) + 6.8y = 1736
776 - 2y + 6.8y = 1736
- 2y + 6.8y = 1736 - 776
4.8y = 960
y = 960/4.8
y = 200
x = 388 - y = 388 - 200
x = 188
Answer:
2115.05?
Step-by-step explanation:
Divided 8,400 to 139 and got 60.43165468...... and rounded it to get 60.43 and then multiplied it to 35 seconds and got 2115.05.
