Walter has 124 bills consisting of 5 dollar bills and 10 dollar bills. If his total amount of money is $840, how many bills of e

Romashka [77]

For this question here are the formulas,
Let T be the number of 10's
Let F be the number 5's

Let us find the 10's first by this formula.
5(124 - T) + 10T = 840
620-5T + 10T = 840
then
5T = 220
5 5

T=44
Now let's find the F using this formula.

5F + 10T = 840
Sustitute T
5F + 10(44) = 840
5F = 400
5 5
F = 80

to Check
F + T = 124
80 + 44 = 124

Find the base of a parallelogram with a slant height of 7cm and an perimeter of 63 cm2

vlada-n [284]

Base of parallelogram b = 24.5 cm

Step-by-step explanation:

We are given:

Perimeter =P= 63 cm^2

Slant Height =a= 7 cm

Base of Parallelogram =b= ?

The formula used is:

$Perimeter = 2(a+b)$

where a is height and b is base

Putting values:

$Perimeter = 2(a+b)\\63=2(7+b)\\63=14+2b\\2b=63-14\\2b=49\\b=\frac{49}{2}\\b=24.5$

So, Base of parallelogram b = 24.5 cm
