If you would like to simplify a - {4b - [a - (5b - c) + 3c - (a - b - 9c)]}, you can do this using the following steps:

a - {4b - [a - (5b - c) + 3c - (a - b - 9c)]} = a - {4b - [a - 5b + c + 3c - a + b + 9c]} = a - {4b - [- 4b + 13c]} = a - {4b + 4b - 13c} = a - {8b - 13c} = a - 8b + 13c

The correct result would be b) a - 8b + 13c.

To simplify a - {4b - [a - (5b - c) + 3c - (a - b - 9c)]} , we group the like terms and perform addition adn subtraction to these grouped terms. no multiplication nor division is applied. In thi case, the grouping results to
a - 4b + a - 5b +c + 3c - a + b + 9c = a -8 b + 13c. answer is B

On Tuesday, Karen finished all her chores in 3/4 of an hour. On Wednesday, she finished her chores in 5/12 of an hour. How much

IRISSAK [1]

1 hour = 60 minutes

Tuesday: 60 divided by 4 = 15. Karen did it 3/4 of a hour so we multiply 15 by 4 which is 45. 45 equals 45 minutes. On Tuesday, Karen finished her chores in 45 minutes

Wednesday: first we divide 60 by 12 which is 5. 5 would equal 5 minutes. now we multiply 5 by 5 which is 25. Karen finished her chores in 25 minutes.

Answer: Karen finished her chores 20 minutes faster on Wednesday than Tuesday.

Hope this helps!

Solve for A if F=MA and F=10 and M=2.5

gogolik [260]

Answer:

$\boxed{\sf A = 4}$

Given:

F = MA

F = 10

M = 2.5

To Find:

Value of A

Step-by-step explanation:

$\sf Substituting \ values \ of \ F \ and \ M \ in \ F = MA:$

$\sf \implies 10 = 2.5A$

$\sf \implies 2.5A = 10$

$\sf Dividing \ both \ side \ of \ 2.5A = 10 \ by \ 2.5:$

$\sf \implies \frac{2.5}{2.5} A = \frac{10}{2.5}$

$\sf \frac{2.5}{2.5} = 1 :$

$\sf \implies A = \frac{10}{2.5}$

$\sf \frac{4 \times \cancel{2.5}}{ \cancel{2.5}} = 4 :$

$\sf \implies A = 4$

List the next three terms in the following sequence:

BlackZzzverrR [31]

1 + 1 = 2
2 + 2 = 4
4 + 3 = 7
7 + 4 = 11
11 + 5 = 16
16 + 6 = 22
22 + 7 = 29
29 + 8 = 37
