Ken purchased school supplies.
Which equation could be used to solve for the cost, x, of the binders?
• He spent $32.88.
• He bought 4 packs of paper, markers, and pencils totaling $9.99.
• He also purchased 3 binders which each cost the same price.
A
4x + 9.99 = 32.88
(В)
3x - 9.99 -32.88
3x + 9.99 = 32.88
D
3x + 4x - 9.99 = 32.88

Step-by-step explanation:

1. Radius=3cm, diameter=6cm

Circumference=3.14×6cm=18.84cm

2. Radius=6in, diameter=12in

Circumference=3.14×12in=37.68in

3. Radius=9mm, diameter=18mm

Circumference=3.14×18mm=56.52mm

Answer:

Given that the equation of the revenue is R=2x2+55x+10 and the equation of the cost is C=2x2 – 15x – 40, you will get the profit by subtracting the revenue from the cost: R-C=P. Therefore, P=(2x2+55x+10)-(2x2 – 15x – 40). You will get P=70x+50 where x is is the number of cellphones sold. If 240 cellphones are sold, then the profit is 16850 dollars.

Step-by-step explanation:

The profit expression is 70x + 50 and the profit if 240 cell phones are sold is $16,850

where,

x = number of cell phones sold.

Profit = Revenue - cost

= (2x² + 55x + 10) - (2x² – 15x – 40)

= 2x² + 55x + 10 - 2x² + 15x + 40

Profit = 70x + 50

Profit = 70x + 50

= 70(240) + 50

= 16,800 + 50

= $16,850

Answer:

t is 11

Step-by-step explanation:

you divide each side by 4 to get rid of the coefficient on t and since theres

no equation left on either side you're left with t=11

Answer:

t = 11

Step-by-step explanation:

ima help explain it to you

Step one since the prime/first number is 4 put 4 as a denominator under both 4 and 44. That is the first step to these equations

Now, you have 4/4 and 44/4 if you divide 4 and 44 you will get 11. If you divide 4 and 4 you will get 1. equally you have 11/1 aka 11.

A EZ STEP IS TO LITTERALLY DIVDE 44 AND 4 RIGHT WHEN U SEE IT LOL

hope this helps!!

Answer:

27 years old

Step-by-step explanation:

What I know

Let D = Dave, S = Sabrina, etc. Then:

(1) [tex]D=0.15S[/tex]

(2) [tex]L=0.75S[/tex]

(3) [tex]R=3.00D[/tex]

(4) [tex]D+S+L+R=141[/tex]

Want to find R. Taking equation 3 and rewriting equation 4, we get

[tex]R=3.00D[/tex]

[tex]R=141-D-S-L[/tex]

So if [tex]R=R[/tex], then

[tex]3D=141-D-S-L-R[/tex]

[tex]4D=141-S-L[/tex] by adding [tex]D[/tex] to both sides.

Using equation 1 and equation 2, I can rewrite everything in terms of [tex]S[/tex] and get:

[tex]4(0.15S)=141-S-0.75S[/tex]

[tex]0.6S=141-1.75S[/tex]

[tex]2.35S=141[/tex] by adding [tex]1.75S[/tex] to both sides.

[tex]S=60[/tex] by dividing 2.35 both sides.

Now that I know Sabrina's age, I'll work towards getting Rhianna's using equation 1 and equation 3:

[tex]D=0.15(60)=9[/tex]

[tex]R=3.00(9)=27[/tex]

Checking my work:

Dave: 9

Sabrina: 60

Luca: 45 (since 9+60+45+27=141)

Rhianna: 27

9 is 15% of 60

45 is 75% of 60

27 is 300% of 9

Answer:

y=3x+2

Step-by-step explanation:

slope= rise/run

rise=3  run=1 slope=3

y intercept is 2

y=3x+2

Answer:

y = 3x + 2

Step-by-step explanation:

(1, 5) and (2, 8)

Slope:

m=(y2-y1)/(x2-x1)

m=(8-5)/(2-1)

m=3/1

m=3

y - y1 = m(x - x1)

y - 5 = 3(x - 1)

y - 5 = 3x - 3

y = 3x + 2

Answer: 7.5 miles per hour

Step-by-step explanation:

First speed was 3 miles per hour.

Second speed was 12 miles per hour.

To do an average, add both speeds and divide by two, which is the number of trips made.

= (3 + 12) / 2

= 15 / 2

= 7.5 miles per hour

  (x, y) ⇒ (x -5, y +3)

Step-by-step explanation:

Pick a point on the original polygon. The extreme left point (at (1, 0)) will do.

Locate the corresponding image point on ABCDE. (It is point B(-4, 3).) Using coordinates, or counting grid squares, determine what must be added to the original point to get the image point.

Here, that addition is 5 squares left and 3 squares up:

  image - original = (-4, 3) -(1, 0) = (-5, 0)

So, the transformation rule adds -5 to each x-coordinate and 3 to each y-coordinate:

   (x, y) ⇒ (x -5, y +3)

Answer:

$20.40 after the discount

Step-by-step explanation:

To find 15% of 24, you multiply 24 and 0.15, which gets you 3.6

Then, to find the price after the discount, you subtract the 15% (the 3.6). So, 24 - 3.6 = $20.40
