Tim has m dollars. Rebecca has $6 less than times the number of dollars that Tim has. Which expression represents the total amount of money that Tim and Rebecca have? If Tim has $70, how much money do Rebecca and Tim have altogether?
Answers
Answer:
$71
Step-by-step explanation:
Tim has M dollars
Rebecca is having (M/10 - 6)
Then, the amount of money Tim and Rebecca are having
= M + M/10 - 6
= (11M/10) - 6 dollars
The expression representing the total amount of money is [(11X/10) - 6]
If Tim is having $70, then total amount both would have together
= [(11 × 70/10) - 6]
= 77 - 6
= $71
Therefore, the expression for the total amount is [(11M/10) - 6] dollars
The total amount both are having together is $71.
Answer:
B. The expression is 11/10m – 6, and the amount is $71.

NS = 24
Step-by-step explanation:
Use the ratio 2:3 and set up a proportion.
2/3 = x/36
Cross multiply
3 * x = 3x
2 * 36 = 72
3x = 72
Divide both sides by 3
3x/3 = 72/3
x = 24
So NS is 24

Mary and Darryl are selling flower bulbs for a school fundraiser. Customers can buy bags of
windflower bulbs and bags of daffodil bulbs. Mary sold 10 bags of windflower bulbs and 4
bags of daffodil bulbs for a total of $226. Darryl sold 6 bags of windflower bulbs and 4 bags of
daffodil bulbs for a total of $166. What is the cost each of one bag of windflower bulbs and
one bag of daffodil bulbs?
Answers
Answer:
15 windflower bulbs
19 daffodil bulbs
Step-by-step explanation:
Given
Represent windflower with W and daffodil with D.
So:
Mary's sales is:
10W + 4D = 226 --- (1)
Darryl's sales is:
6W + 4D = 166 ---- (2)
Required
Solve for W and D
We'll make use of elimination method.
Start by subtracting (2) from (1)
10W - 6W + 4D - 4D = 226 - 166
4W = 60
Multiply both sides by ¼
¼ * 4W = 60 * ¼
W = 60 * ¼
W = 15
Substitute 15 for W in (1)
10W + 4D = 226
10 * 15 + 4D = 226
150 + 4D = 226
Collect like terms
4D = 226 - 150
4D = 76
Multiply both sides by ¼.
¼ * 4D = 76 * ¼.
D = 19

Answer:

Step-by-step explanation:
3(x+5)-3 = 2(3x + 1) - 3x
open the parenthesis
3x + 15 - 3 = 6x + 3 - 3x
add 3x to both sides of the equation
3x + 3x + 15 - 3 = 6x + 3 - 3x + 3x
combine like terms
6x + 15 - 3 = 6x + 3
add 3 to both sides of the equation
6x + 15 - 3 + 3 = 6x + 3 + 3
6x + 15 = 6x + 6
subtract 6 from both sides of the equation
6x + 15 - 6 = 6x + 6 - 6
6x + 15 - 6 = 6x
6x + 9 = 6x
subtract 6x from both sides of the equation
9 = 0
since 9 does not equal 0, the answer is no solutions
