Lauren ran the 400-meter dash in fifty-three and ten hundredths seconds. How
should this decimal be written correctly?



A: . 5310

B: 53.10

C: 53.01

Answer:

x < 3

Step-by-step explanation:

−4x − 8 > −20

Add 8 to both sides.

-4x > -12

Divide both sides by -4. Remember that when you multiply or divide both sides of an inequality by a negative number, the direction of the inequality sign changes.

-4x/(-4) < -12/(-4)

x < 3

Answer:

39 cars/hour

Step-by-step explanation:

We are trying to find the rate of cars/hour. So we need to divide the amount of cars by the amount of hours.

273/7 = 39

The wash detailed cars at a rate of 39 cars per hour.

Answer:

x = ±9

Step-by-step explanation:

x² - 55 = 26

   +55   + 55

     x² = 81

     x = √81

     x = ± 9

Answer:

x = 9, -9

Step-by-step explanation:

x^2 - 55 = 26

x^2 = 81.

Now, you might think that x = 9, but don't be fooled. -9 squared is also equal to 81.

So, x = 9, -9

FGCE

Step-by-step explanation:

Answer:

FGCE

Step-by-step explanation:

1. 3x - 9 = 30

add 9 to 30 ( 30 + 9 = 39) divide 39 by 3 (39 ÷ 3 = 13)

2. x/5 + 4 = 6

subtract 4 from 6 (6 - 4 = 2) multiply 2 by 5 (2 x 5 = 10)

3. x/2 + 6.5 = 8

subtract 6.5 from 8 (8 - 6.5 = 1.5) multiply 2 by 1.5 (2 x 1.5 = 3)

4. -2x + 2 = 18

subtract 2 from 18 (18 - 2 = 16) divide -2 from 16 (16 ÷ -2 = -8)

Answer:

y=3+4x

y=3x-4

Step-by-step explanation:

-4x+y=-3

Add 4x to both sides

y=4x-3

-6x+2y=-8

Add 6x to both sides

2y=6x-8

Divide by 2 on both sides

y=3x-4

Answer:a

the number of drinks Liam can buy is 4 without going over his limit.

Step-by-step explanation:

Answer:

2x squared - 8

Step-by-step explanation:

For this kind of equation, we use the distributive property

So in the image below I used a box method (that's how I learned it in school)

So since -4x and 4x cancel each other out, or amount to 0, we don't put anything for those. So the equation left is 2x squared - 8

$1.50 for each box

Step-by-step explanation:

$18 divided by 12 boxes = $1.50 for each box

Answer:

C

Step-by-step explanation:

The surface area of a cylinder is given by the formula:

[tex]SA=2\pi rh+2\pi r^2[/tex]

Where h is the height and r is the radius of the cylinder.

The given radius is 6 and the height is 24.

We are also using 3.14 for π.

Therefore;

[tex]SA\approx 2(3.14)(6)(24)+2(3.14)(6)^2[/tex]

Evaluate:

[tex]SA\approx1130.4\approx 1130[/tex]

The answer is C.

Answer:

Answer:

x = -2

Step-by-step explanation:

Answer:

x=−2

Step-by-step explanation:

Let's solve your equation step-by-step.

3x+11=5

Step 1: Subtract 11 from both sides.

3x+11−11=5−11

3x=−6

Step 2: Divide both sides by 3.

3x/3=−6/3

x=−2

60 minutes to fold 120 boxes

Step-by-step explanation:

easy, simply divide 40 by 2 then multiply it by 3 because this will mean hes folded 120 boxes...

40 divided by 2 is 20 times 3 is 60

80 divided by 2 is 40 times 3 is 120.

Answer:

3200

Step-by-step explanation:

you will multiply 80 by 40

80×40=3200

Answer:

Each transversal crossing a line generates 2 pairs of vertical angles and for 3 transversal crossing the same line it will be 3 x2 = 6 pairs (or 12 angles)

Answer:

You are given a right triangle. The sum of the two acute angles should add up to 90 degrees. Set up an equation using the expressions given and solve for x. Once you know the value of x plug it back into each expression to find the measure for each angle.

Step-by-step explanation:

Angle 1 + angle 2 = 90

solve for x = ____

Plug the value into each expression to find the measure of each angle.

Answer:

D

Step-by-step explanation:

(2x+6)+(5x+14)=90

7x+20=90

7x=70

x=10

(2x+6)=26°

(5x+14)=64°

Answer:

x=30° y=4

Step-by-step explanation:

[tex] \frac{y}{8} = \frac{2.5}{5} [/tex]

cross multiple

5y=8(2.5)

5y=20

divide 5 by 20

and you should y=4

since the polygons are similar x should have the same degrees as the bigger polygon

Answer: Y=4

Step-by-step explanation

Since the inside of a triangle is 180 degrees the 30 degrees plus the 90 degree corner minus the total inside degree so the other corner is 60 degrees. the dialation is 62.50  percent or .625 in decimal form which makes the vareable  y equals 4 once you divide 2.5 by .625
