A good estimate for a door in a public setting is about 4 feet
.05n + .10d = 6.10
n + d = 67
n = 67-d
.05(67-d) + .10d = 6.10
3.35 -.05d + .10d = 6.10
3.35 + .05d = 6.10
3.35-3.35 +.05d = 6.10-3.35
0.05d = 2.75
0.05d/0.05 = 2.75/0.05
d = 55
n + d = 67
n + 55 = 67
n = 12
There are 12 nickels
Check
0.5(12) + .10(55) = $6.10
.60 + 5.50 =$6.10
$6.10 = $6.10
Answer:
Below.
Step-by-step explanation:
So 4-6 to 8-12.
4 can be devised by 12, and so can 6.
4:8 6:12
If we flip them over we can find the dilation.
so?
8:4 12:6
Each can be divided by 2.
So the factor if dilation is 2.
Answer:
The discount was approximately 48%.
Step-by-step explanation:
The general forumla to calculate percent change (increase or decrease) is:
x 100
In this case, the original price was $28.00, but the new price (after discount) was $14.60. Putting these values into the formula:
x 100 = 48%.
The terms of an expression are the numbers separated by a "+" or a "j." in this case the terms would be 6x, 5y, and 3. So your answer would be C.
