8x - 6y=-16<br>5x + y = 28<br><br>In using Elimination?​
Anettt [7]
Multiple (5x+y= 28) by 6 giving you 30x +6y =168 and then you would add the two equations together, giving you 38x = 152, divide both sides by 38, giving you 4. after this, you would sub x=4 into one of the equations (i’m using the 5x+ y =28) which would give me 20 + y = 28, subtract 20 by both sides, giving you y= 8. so your answer is (4,8)

one half the cost of a dress decreased by $12 is the same as 2/5 the cost of a dress. What is the cost of the dress?
guajiro [1.7K]

Answer:

$120

Step-by-step explanation:

Let the cost of the dress be "c"

ONE HALF the cost DECREASED by 12, can be written as:

\frac{1}{2}c-12

2/5th the cost of dress, can be written as:

\frac{2}{5}c

Now, we equate both parts and solve for c to get cost of dress. Shown below:

\frac{1}{2}c-12=\frac{2}{5}c\\\frac{1}{2}c-\frac{2}{5}c=12\\\frac{5-4}{10}c=12\\\frac{1}{10}c=12\\c=\frac{12}{\frac{1}{10}}\\c=12*10\\c=120

Thus,

The ccost of the dress is $120

Carrie manages a catering company. She rented 325 chairs each week for the first two weeks of May. Carrie rented 750 chairs each
I am Lyosha [343]

Answer: 2127 chairs

Step-by-step explanation:

Given : Carrie manages a catering company. She rented 325 chairs each week for the first two weeks of May.

Then by using Multiplication operation , the total number of chairs ordered in first two weeks of May. = 2\times325=650   (1)

Also,  Carrie rented 750 chairs each week for the first two weeks of April.

Then, the total number of chairs ordered in first two weeks of April = 2\times 750 =1500  (2)

Total chairs ordered in 4 weeks = 650+1500     [add (1) and (2)]

 =2150

The chair rental company forgot to send 23 chairs, then number of chairs received by Carrie = 2150-23 =2127

Hence, Carrie received 2127 chairs in those 4 weeks.
