31) 1.111

32) 1.5

33) 1.666

34) 2.266

35) 1.14285714286

36) 3.9

37) 3.333

Step-by-step explanation:

31) 1  1/4 × 8/9

multiply the denominator(4) with 1 which is 4 itself, then add 4 with the numerator(1) which is 5. therefore you will get,

⇒5/4 × 8/9

⇒ 5×8/4×9

⇒40/36

⇒10/9

32) 2/3 × 2  1/4

multiply the denominator(4) with 2 which is 8, then add 8 with the numerator(1) which is 9. therefore you will get,

⇒2/3 × 9/4

⇒2×9/3×4

⇒18/12

⇒3/2

33) 2  2/9 × 3/4

multiply the denominator(9) with 2 which is 18, then add 18 with the numerator(2) which is 20. therefore you will get,

⇒20/9 × 3/4

⇒20×3/9×4

⇒60/36

Answer:

9(m - 3) + 3m = 7m + 43

=>9m - 27 + 3m = 7m + 43

=> 12m - 27 - 7m = 43

=> 5m - 27 = 43

=> 5m = 70

=> m = 70/5 = 14

Answer:

m=14

Step-by-step explanation:

start with your parenthesis and multiply 9 to m-3 which makes that 9m-27+3m=7m+43

add your m together making that 12m-27=7m+43

add 27 to both sides equalling 12m=7m+70

subtract 7m from both sides resulting in 5m=70

divide both sides by 5 equalling m=14

Answer:

They should protect itself because they would be in alot of trouble

Step-by-step explanation:

Answer:

s = 0.3m

Step-by-step explanation:

Given that s varies directly with m then the equation relating them is

s = km ← k is the constant of variation

To find k use the condition

s = 9 when m = 30

9 = 30k ( divide both sides by 30 )

[tex]\frac{9}{30}[/tex] = k

s = [tex]\frac{9}{30}[/tex] m or

s = 0.3m ← equation of variation

50

Step-by-step explanation:

you just subtract the 29 from 79

There are 50 candies left in the jar.

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

There are 79 candies in the Jar.

Aaron remove 29 candies from the jar.

Now,

Total number of candies in the jar =n 79

And, Aaron remove 29 candies from the jar.

Thus, Left candies in the jar = 79 - 29

                                           = 50

Therefore, There are 50 candies left in the jar.

Answer:

let's see what to do buddy...

Step-by-step explanation:

We have this equation to find the distance between two points :

a = ( 2 , 0 ) and b = ( -4 , 6 )

[tex]distance = \sqrt{ {( \: y(b) - y(a) \: })^{2} + ( \: {x(b) - x(a)} \: )^{2} } \\ [/tex]

Now just need to put the coordinates in the equation :

[tex]distance = \sqrt{ ({6 - 0})^{2} + ({ - 4 - 2})^{2} } \\ distance = \sqrt{ {6}^{2} + ({ - 6})^{2} } = \sqrt{36 + 36} \\ distance = \sqrt{36 \times 2} = 6 \sqrt{2} [/tex]

And we're done.

Thanks for watching buddy good luck.

The Answer is A I'm positive

Answer:

Step-by-step explanation:

[tex] \frac{2}{3} x - 1 = 4 \\ [/tex]

Move 1 to the other side of the equation

That's

[tex] \frac{2}{3} x = 4 + 1 \\ \frac{2}{3} x = 5[/tex]

Multiply through by 3 to eliminate the fraction

We have

[tex]3 \times \frac{2}{3} x = 5 \times 3 \\ 2x = 15[/tex]

Divide both sides by 2

[tex] \frac{2x}{2} = \frac{15}{2} \\ [/tex]

We have the final answer as

[tex]x = \frac{15}{2} \\ [/tex]

y = 2x + 3

Step-by-step explanation:

Based on the information provided we can use the values to write a proper algebraic equation like the following one ...

y = 2x + 3

The equation above states that the total number of paper that is recycled is equal to the 2 kilograms that are being recycled on a weekly basis plus the 3 kilograms that have already been recycled. This means that the value of y depends on the input given for the value of x which is the number of weeks that have passed.
