Answer:

8/15

Step-by-step explanation:

7/10 = 21/30

1/6 = 5/30

21/30-5/30 = 16/30=8/15

Answer:

32/60

Step-by-step explanation:

7/10-1/6

6 and 10 can both go into 60 so you do

10x6 and 6x10 u get 60 as the denominator now you have to multiply the same for the numerator and you get 10/60 and 42/60 now subtract

42-10= 32

32/60

Answer:

[tex]18c - 30d + 36[/tex]

Step-by-step explanation:

Given

[tex]6(3c - 5d + 6)[/tex]

Required

Expand

[tex]6(3c - 5d + 6)[/tex]

Open bracket

[tex]6(3c - 5d + 6) = 6*3c - 6*5d + 6*6[/tex]

[tex]6(3c - 5d + 6) = 18c - 30d + 36[/tex]

So, the result of the expression is:

[tex]18c - 30d + 36[/tex]

Answer:

Rumble charters

Step-by-step explanation:

OK bus line:

55 +3.50(25)

55+87.5

=142.50

Rumble charters:

75+2.25(25)

75+56.25

=131.25

From looking at the steps we could tell that Rumble charters bus line would be cheaper.

its the second one

Step-by-step explanation:

1. 3.50×25+55=142.5

2. 2.25×25+75=131.25

Answer:

I think the answer is 8

Step-by-step explanation:

first you do 6 times 6

then you do 36-20

next do 32 divided by 4 and then you subtract that all

Answer:

y=(-1/3)x

Step-by-step explanation:

y=mx+b

(x,y)

put in the first point into y=mx+b

2=m(-6)+b

then the second point is (6,-2)

put the point into y=mx+b

-2=6m+b

----------------------------

Put both equations in a system of equations

-2=6m+b

2=m(-6)+b

solve for m and b

-1/3=m and 0=b

so put that back into y=mx+b

y=(-1/3)x+0

so that is the only line that passes through both points

Answer:

7/12

Step-by-step explanation:

turn 5/6 and 1/4 to have same denominator (12).

10/12 - 3/12

7/12

3+(5+4)(8-6)

3+(9)(2)

3+18

Answer:

Row 1

Step-by-step explanation:

If you divide the number of oranges in each row by their number of boxes, you always get 13 oranges per box.

(156/12 = 13)

(130/10 = 13)

(91/7 = 13)

(65/5 = 13)

But, in Row 1, he made a mistake: 13/2 = 6.5 The mistake here is that Row 1's "number of boxes" should be 1, not 2, to make this eqation true. If we did this, then we will get 13 as our "number of oranges" instead of 6.5, becuase the equation will now be 13/1 = 13 and his table will be correct.

Row 1 has the mistake.

Answer:C Because there the same sides

Answer:

12t - 1

Step-by-step explanation:

(9t+5) + (3t-6)

9t + 5 + 3t - 6

12t - 1

Answer:

Step-by-step explanation:

19)

6/x = x/12

x^2 = 72

x = √72

x = 6√2

y^2 = 12^2 + (√72)^2

y^2 = 144 + 72

y^2 = 216

y = 6√6

21)

14 - 8 = 6

y/8 = 6/y

y^2 = 48

y = √48

y = 4√3

x^2 = 6^2 +(√48)^2

x^2 = 36 + 48

x^2 = 84

x = √84

x = 2√21

Answer:

1 2/3

Step-by-step explanation:

7 1/2x2/9

The required number of tiles will be 34 covering the length of the entryway.

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

For example 4×2 = 8

We have been given that the tiles are each 2/9 feet long, and the entryway is 7 1/2 feet long.

We have to determine the number of tiles will he need to buy in order to cover the length of the entryway.

According to the given question, the required solution would be as:

So the number of tiles covering the length of the entryway will be

⇒ 7 1/2 ÷ (2/9)

⇒ 15/2 ÷ (2/9)

⇒ 15/2 / (2/9)

Reciprocal the term in the denominator

⇒ (15/2) x (9/2)

Apply the multiplication operation,

⇒ 135/4

Apply the division operation,

⇒ 34

Thus, the required number of tiles will be 34 covering the length of the entryway.

First u have to find the bisector,then u have to descrese 18

Answer:

the first one and the last one

Step-by-step explanation:

Answer:

A and C

Step-by-step explanation:

A is equivalent to the expression because it just expanded the equation more a bit. It's distributed, but not solved. Like 3.2 (4p +8.5) is the same as 3.2 (4p) + 3.2 (8.5) since in both 3.2 is being distributed or multiplied by both numbers.

C is equivalent to the expression because it simplified the expression more. 3.2 times 4p is 12.8p. 3.2 times 8.5 is 27.2. The expression cannot be simplified.

Hope I helped! :)
