can someone help me with this please ? D: 7th grade math

Answer:

38 7/18

Step-by-step explanation:

The LCD of denominators 3, 9 and 2 is 72; all three of these divide evenly into 72.  Rewriting the original problem, we get

7 24/72 - 5 64/72 + 8 36/72

Rewriting the original quantities as improper fractions, we get

22/3 - 53/9 + 17/2

Applying the LCD, we get

24(22)       8(53)       17(36)        2764

----------- - ----------- + ---------- = ------------ = 38 7/18

   72             72           72             72

[tex]7\frac{1}{3}-5\frac{8}{9}+8\frac{1}{2}= \frac{22}{3}-\frac{53}{9} +\frac{17}{2} = \frac{132}{18}-\frac{106}{18}+\frac{153}{18} =\frac{132-106+153}{18} =\frac{179}{18}=9\frac{17}{18}[/tex]

ok done. Thank to me :>

Answer:

3.391 Gallons Per Minute

Step-by-step explanation:

78/23=3.391

Round 3.391 to 3.4

Answer:

≈3.39130434783 gallons per minute

Step-by-step explanation:

The information we get is a ratio, describing how many gallons of water will be wasted in 23 minutes, expressed as:

[tex]78 : 23[/tex]  OR  [tex]\frac{78}{23}[/tex]

We will use the fraction, the denominator is representing the time, which in this case, is 23 minutes. We want to have the denominator as 1 to find how much water will be spilled in one minute, to do this, we can divide both the numerator and denominator by 23:

[tex]\frac{78/23}{23/23} \\ =\frac{3.39130434783...}{1}[/tex]

And of course, if there's a need to round, go ahead.

And please do not waste water!

Answer:

8.06

Step-by-step explanation:

Decimals go in the order 10ths hundredths thousandths ten thousandths and so on. In rounding any decimal, one number gets added to the left if the number is 5 or over and the number is discarded if it is lower than 5.

for example if the number was 1.2345      5 would make 4 5 1.235 then 5woould make 3 4 1.24 but if you want to round to a smaller number the other numbers would not go up the numbers would just be discarded.

Answer:

2/13

Step-by-step explanation:

To find a fraction of a fraction, you just multiply the two.

So 22/39 x 3/11 is 22x39 over 3/11

or 66/429.

Simplified would be 22/39.

The value of 22 / 39 of 3 / 11 on simplification is 6 / 39.

The fundamental concept of making the same number of additions repeatedly is represented by the action of multiplication. The results of multiplying two or more integers are known as the products, and the factors that are used in the multiplication are referred to as the factors.

Given:

22 / 39 of 3 / 11

As we know of means multiplication then,

22 / 39 × 3 / 11

(22 × 3) / (39 × 11)

66 / 429

This can be simplified as,

6 / 39

Answer:

112.5 seconds

Step-by-step explanation:

Stephanie ran four laps around the school track in 7 minutes and 30 seconds. How many seconds per lap is that?

You need to do convert 7 minutes in to seconds because you cannot do anything to this unless you convert it.

Remember

1 minute = 60 seconds.

So do 7 times 60.

7 × 60

Which is 420 seconds.

Now add the 30 seconds to that.

420 + 30.

Which is 450 seconds.

Now divided 450 by 4.

450 ÷ 4.

Which is 112.5 seconds per lap.

Answer:

The answer is B) a = -7/16

Step-by-step explanation:

3/4 + 4a/7 = 6a/7 + 7/8

By transposing, we get

=> 3/4 - 7/8 = 6a/7 - 4a/7

=> (by taking LCM) 6-7/8 = 6a-4a/7

=> -1/8 = 2a/7

=> -7 = 16a (by cross multiplication)

=> a = -7/16

Now first position is filled in 4 ways (can use 2 3 7 9) that implies 4C1

then second position is filled in 3 ways since for first position we used a digit

and the condition is that not to repeat the digits, so it is done in 3C1 ways.

so the answer is 4*3 or (4C1*3C1)=12;
