James has a rectangular plot of land that is 250 feet long and x feet wide. He wants to build a fence around the plot of the land. If the perimeter of the plot is 942 feet, what is the value of x?
Answer:
= 221
Step-by-step explanation:
Lenght = 250
Width= x
Perimeter = 2 (l+b) = 942
2 x (250 +x) = 942
500 + 2x = 942
2x = 942 - 500= 442
x = 442 /2 = 221

A toll road company has two plans for customers. One plan charges $10 per month for rental of a transponder (a box that identifies your car on the toll roads) plus $0.60 per mile driven. The second plan does not require that you rent a transponder. Instead, it charges customers $0.75 per mile driven on the toll road. Find the minimum number of miles you would need to drive in a month to make the first deal a better deal.
Answer:
The minimum number of miles you would need to drive in a month to make the first deal a better deal is 66.6 miles.
Step-by-step explanation:
For the first deal to be a better deal it has to cost less than the second plan and you can write an equation in which the first plan has a lower cost than the second one:
10+0.60m<0.75m, where:
m is the number of miles driven
Now, you can solve for m:
10<0.75m-0.60m
10<0.15m
10/0.15<m
m>66.6
According to this, the answer is that the minimum number of miles you would need to drive in a month to make the first deal a better deal is 66.6 miles.
find the number of inches needed to represent 300 miles if one fourth in =50 mi
Answer:
1.5 in
Step-by-step explanation:
if one quarter of an inch represents 50 mi then and we know 50 x 6 = 300 then you would need 6 fourths of an inch or one and a half inches.

Answer:
he ate 12/12 which means the dinasour ate all of the plant
Step-by-step explanation:
i cant lie this is a wierd question cause it seems to obvious but here it is....
10/12+ 2/12= 12/12
12/12=1 whole the dinasour ate the entire plant
Answer: 10/12 + 2/12 = 12/12 or 1 whole
Step-by-step explanation: Since it says at first the dino ate 10/12 and then after it ate 2/12 more. When your adding fractions the denominator doesn't change but the numerator does. Therefore its basically saying what's 10+2 which = 12 then you put the denominator on the bottom which is 12/12 if you want to simplify it. It turns to a 1 whole

pleaseee help it's due tonight and i don't know what it wants and how to do it
Answer:
solve
Step-by-step explanation:
plus . minus and divide
Answer:
1- Let x = original price then
x - .20x = 48
x(1 - .20) = 48
x(.80) = 48
x = 48/.80
x = $60
2-Let "x" be the number of lessons.
240 - 15x = 0
240 = 15x
x = 16 lessons
3-divide equation by 2:
(2W-4) + W = 32
2W - 4 + W = 32
2W + W = 32 + 4
3W = 36
W = 36/3
W = 12 cm
Find the Length using L = 2W-4:
L = 2(12) - 4
L = 20 cm
Check: 2(20) + 2(12) = 64
4-P stands for the original price. The 90 stands for 90 %. Wendy paid 100-10, or 90 %.
