( I had an equation and I wanted to share this meme thing)

Answers

Answer:

x = - 5, x = - 1

Step-by-step explanation:

Given

(x + 3)² = 4 ( take the square root of both sides )

x + 3 = ± [tex]\sqrt{4}[/tex] = ± 2 ( subtract 3 from both sides )

x = - 3 ± 2

Then

x = - 3 - 2 = - 5

x = - 3 + 2 = - 1

You are offered two different sales jobs. The first company offers a straight commission of 8% of the sales. The second company offers a salary of $ 500 per week plus 3% of the sales. How much would you have to sell in a week in order for the straight commission offer to be at least as good

Answers

Answer:

You would have to sell 10,000 in a week for the straight commission offer to be at least as good.

Step-by-step explanation:

From the information provided, you can find how much you would have to sell in a week in order for the straight commission offer to be at least as good by establishing an equation in which the amount earned in the first company is equal to the amount earned in the second company:

0.08x=500+0.03x, where x is the amount of sales

Now, you can solve for x:

0.08x-0.03x=500

0.05x=500

x=500/0.05

x=10,000

According to this, the answer is that you would have to sell 10,000 in a week for the straight commission offer to be at least as good.

A welcome kit contains 3 grocery store and seven drugstore coupons. The coupons are worth $45. Another welcome kit contains three grocery store coupons and six drugstore coupons worth $42. What is the value of each grocery coupon and each drug store coupon?

Answers

Answer:

The value of each grocery store coupon is $6

Then the value of each drugstore coupon is $3.

Step-by-step explanation:

Let's define:

G = value of a grocery store coupon.

D = value of a drugstore coupon.

We know that:

"A welcome kit contains 3 grocery store and seven drugstore coupons. The coupons are worth $45"

We can write this as:

3*G + 7*D = $45

And we also know that:

"Another welcome kit contains three grocery store coupons and six drugstore coupons worth $42"

We can write this as:

3*G + 6*D = $42

Then we have the system of equations:

3*G + 7*D = $45

3*G + 6*D = $42

To solve this, we can isolate the term "3*G" in one of the equations (because it appears on both of them)

Let's isolate it on the second equation:

3*G = $42 - 6*D

Now let's replace this on the first equation:

($42 - 6*D) + 7*D = $45

$42 + D = $45

D = $45 - $42 = $3

Then the value of each drugstore coupon is $3.

And we also have the relation:

3*G = $42 - 6*D

We can just replace the value of D to get:

3*G = $42 - 6*$3 = $42 - $24 = $18

G = $18/3 = $6

The value of each grocery store coupon is $6

Cynthia Besch wants to buy a rug for a room that is 24 ft wide and 32 ft long. She wants to leave a uniform strip of floor around the rug. She can afford to buy 560 square feet of carpeting. What dimensions should the rug​ have?

Answers

Answer:

[tex]D=(20.42)(28.42)[/tex]

Step-by-step explanation:

From the question we are told that

Width [tex]W=24ft[/tex]

Length [tex]L=32ft[/tex]

She can afford to buy 560 square feet of carpeting

Let

[tex]S=width\ of\ strip[/tex]

Generally the Dimension of the rug is mathematically given as

Width of Rug [tex]W' = (24- 2S)ft[/tex]

Length of Rug [tex]L'= (32-2S) ft[/tex]

Generally the width of strip S is mathematically given by

[tex](32-2s)*(24-2s)=560[/tex]

[tex]-4s-112s+208=0[/tex]

[tex]s_1=-29.7\\s_2=1.748[/tex]

Therefore the width is

[tex]s=1.748[/tex]

Generally the dimension of the rug D is mathematically given as

Width of Rug [tex]W' = (24- 2s)ft[/tex]

[tex]W' = (24- 2(1.79))ft[/tex]

[tex]W' =20.42ft[/tex]

Length of Rug [tex]L'= (32-2S) ft[/tex]

[tex]L'= (32-2(1.79)) ft[/tex]

[tex]L'=28.42 ft[/tex]

Therefore dimension of Rug is given by

[tex]D=(20.42)(28.42)[/tex]
