Fred and ethyl had 132 flowers altogether at first. After Fred sold 1/4 of his flowers and Ethyl sold 48 of her flowers, they had the same number of flowers left. How many did they each have at first?

Answers

F + E = 132
3/4 F = E - 48 ( after Fred sold 1/4 of his flowers there is 3/4 flowers left )
--------------------
E = 132 - F
3/4 F = 132 - F - 48
3/4 F + F = 84
7/4 F = 84
F = 84 : 7/4 = 84 * 4/7 = 48
E = 132 - 48 = 84
We can prove it: 3/4 * 48 = 84 - 48
36 = 36 ( correct )
Answer:
Fred had 48 flowers and Ethel 84 flowers.

Fred had 48 flowers.

Ethyl had 84 flowers.

Simultaneous Linear Equations could be solved by using several methods such as :

Elimination Method

Substitution Method

Graph Method

If we have two linear equations with 2 variables x and y , then we need to find the value of x and y that satisfying the two equations simultaneously.

Let us tackle the problem!

Let :

Number of Fred's Flowers = f

Number of Ethyl's Flowers = e

Fred and ethyl had 132 flowers altogether at first.

$f + e = 132$

$f = 132 - e$ → Equation 1

After Fred sold 1/4 of his flowers and Ethyl sold 48 of her flowers, they had the same number of flowers left.

$f - (1)/(4)f = e - 48$

$(3)/(4)f = e - 48$

$(3)/(4)(132 - e) = e - 48$ ← Equation 1

$(3)/(4)(132) - (3)/(4)e = e - 48$

$99 + 48 = (3)/(4)e + e$

$147 = (7)/(4)e$

$e = 147 / (7)/(4)$

$e = \boxed{84}$

$f = 132 - e$

$f = 132 - 84$

$f = \boxed {48}$

Adam was collecting cans for recycling. in 5 months he had collected 449 bags with 50 cans inside each bag .how many cans did he have total

Answers

For this problem you would just multiply the number of bags by the contents of each bag, so 449*50. The answer would be 22,450 cans. I hope this helps, if you need more assistance tell me, and have a nice day! :)

Use distributive property to simply 0.75(3.5a-6b)

Answers

0.75 × 3.5a = 2.625a
0.75 × 6b = 4.5b
your answer is 2.625a - 4.5b

Mulitiply everything on the outside of the brackets to everything inside so:
0.75 • 3.5a = 2.625a
And
0.75 • 6b = 4.5b

2.625a - 4.5b would be your simplified answer
