8x27 using distributive property and mental math

Answer:

Step-by-step explanation:

(x/13) cm

Answer: x/13 = y.

Step-by-step explanation: Let x represent the total length of the timber. Then, 13 will represent the number of pieces it will be divided into. Finally, y represents the length of each individual size.

Answer:

0.619

Step-by-step explanation:

Answer:

0.619

Step-by-step explanation:

Fist divide 13/21. I used a claulator since thats allows in my class. When you do that you get 0.619047619. to round we look at the thrid and fourth decimal places, which are 9 and 0. Since zero is less than nine we round down to get the answer.

Answer:

A) 40 + d

B) 45 days

Step-by-step explanation:

A)

total cost = (cost of the air conditioner itself) + (money charged per day)*(days)

cost of air conditioner itself = $40

money charged per day = $1

days = d

40 + 1*d

= 40 + d

B)

total cost = 40 + d

total cost = $85

85 = 40 + d

45 = d

Time used the air conditioner for 45 days.

Answer:

6

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

f(x) = √2x-4

f(20) = √2(20)-4

f(20) = √40-4

f(20) = √36

f(20) = 6

Answer:

2^3*3

Step-by-step explanation:

Answer:

x = 1 and y = 6

Step-by-step explanation:

Add these equations

-2x+y=4

2x+y=8

2y=12

    2

y = 6

Plug in 12 for y.

-2x+(6) = 4

     -6    -6

-2x = -2

     -2

x = 1

Answer:

AE = 30

GD = 5

GF = 10

Step-by-step explanation:

Centroid of medians divide median in the ratio 2 : 1

Therefore,

AG : GE : 2 : 1

Let AG = 2x & GE = x

Since, AG = 20....(given)

Therefore, 2x = 20

x = 20/2

x = 10

GE = x = 10

AE = AG + GE = 20 + 10 = 30

CG : GD : 2 : 1

Let CG = 2x & GD = x

Since, CG = 10....(given)

Therefore, 2x = 10

x = 10/2

x = 5

Since, GD = x

Therefore, GD = 5

BF = 30

2x + x = 30

3x = 30

x = 30/3

x = 10

GF = 10

Answer:

c, 50

Step-by-step explanation:

120-24= 96

Since we are measuring the size of one of the halves, you have to split that number in half, so 96 ÷ 2= 48.

48 rounds up to 50, so 50 is the answer

Answer:

1. $0.24

2. 89.2 miles

Step-by-step explanation:

To get the unit price, divide the total price by the amount that was purchased.

1. 3.12/13 = $0.24

For the second one, get the distance traveled per hour first then multiply by 8.

22.3 / 2 = 11.15

11.15 x 8 = 89.2

Answer:

This would be D. (6, 5)

Step-by-step explanation:

When moving 9 to the right, you take -3 and add 9 to it, which gives you 6.

Do the same thing with 15, but subtract 10 from it, since you are going to the left. This gives you 5.

Therefore, your answer should be (6, 5)

-3 + 9 = 6

15 + 10 = 5

The format of a logarithmic equation is:

[tex]a^{b} = c\\\\log_{a}c = b[/tex]

In this instance:

a = e

b = 3x

c = 7

Rewrite as the logarithmic equation:

[tex]log_{e}7 = 3x[/tex]

Solve. Evaluate [tex]log_{e}7[/tex] and use algebra to find x:

[tex]1.946 = 3x\\\\x = 0.649[/tex]

Answer:

rock climb costs $7

Step-by-step explanation:

2 laser tags +3 rock climb = $31   ( 1 )

4 laser tags + 1 rock climb = $27   (2)

multipy (1) by -2 and add the equations

-4 laser tags -6 rock climb = $ -62  

4 laser tags + 1 rock climb = $27

-6 rock climb +1 rock climb = -62+27

-5 rock climb = -35 divide both sides by -5

1 rock climb = $7
