hey, guys id prefer it if someone could walk me through this step by step thx! Write an expression that is equivalent to the expression below. 3.5(2.4x+8.6y)-2.9(5x-6.5y)-(3.1x+7y)

Answer:

Step-by-step explanation:12/4 can be simplified into 6/2 which can be simplified into 3/1. 3/1 is your answer!!

Answer:

Three

Step-by-step explanation: The reason why the missing number is three is because if you divide 12 by 4 you get 3.

Answer:

Step-by-step explanation:

Answer:

18

Step-by-step explanation:

If you take a look at it, its quite similar to the example

Since they are using the same dimensions (1.5) you multiply 1.5 x number x 1.5 again

1/8 as a reciprocal is 8

so you do 1.5 x 8 x 1.5 which gives you 18

Answer:

105, D, 13,9899/138530? not sure on that one

Answer:

29.) D

31.)  145 girls

32.) 13,986  ,  13,967

Step-by-step explanation:

For 29 you need to find the total cost of each item. 2x1 would be $2 for the water, 1x3 would be $3 for the sandwich. Remember what operation you used to find the products. In this case, it would be D.

For 31 you need to find the number of girls at the tournament. For that you would write out the total cost of children, and subtract the number of boys from that to get the total.

For 32 you just need 2 random numbers that will round up to 14,000. Any number that is 5 or above will round up, and any number that is 4 and under will round down.

Answer:

The answer is a, 21/104

Step-by-step explanation:

First:

Convert any mixed numbers to fractions.

Then your initial equation becomes:

21/8 ÷13/1

Applying the fractions formula for division,

=21×18×13

=21/104

=21/104

Answer:

ANSWER

M=(−72,12).

Step-by-step explanation:

The midpoint for two points P=(x1,y1) and Q=(x2,y2) is

M=(x1+x22,y1+y22).

We have that x1=−3, y1=−1, x2=−4, y2=2.

So, M=(−3+(−4)2,−1+(2)2)=(−72,12)

Answer:

The answer is

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(−3,−1) and (−4,2)

The midpoint is

[tex]M = ( \frac{ - 3 - 4}{2} \: , \: \frac{ - 1 + 2}{2} ) \\ = ( - \frac{7}{2} \: , \: \frac{1}{2} )[/tex]

We have the final answer as

Answer:

γ = [tex]\lim_{n \to \infty}\sum_{k=1}^n (\frac{1}{k}-ln(n) )[/tex]

or

γ = -∞

Step-by-step explanation:

Let's solve what's inside the limit first.

We see that we need to take the sum of the entire thing. Since it is multivariable and we are given 1 variable, it stays the same.

Now we move on to the limit.

We replace n in the summative with infinity.

The natural log of infinity is infinity.

1 minus infinity would be negative infinity.

The sum of negative infinity of k = 1 is negative infinity.

So the limit as n approaches infinity would be negative infinity.

If we were to simplify this mathematically, it would just be the same equation.

Answer:

437.4 meters squared

Step-by-step explanation:

7.2*4.5=32.4=b

3*4.5=13.5=h

b*h=a

32.4*13.5=437.4m^2

Answer:

320km = 12L

296 km = xL

x = (296 × 12)/320

x = 11.1 liters

Step-by-step explanation:

Answer:

-7/24 = r

Step-by-step explanation:

3/8 = r + 2/3

Subtract 2/3 from each side

3/8-2/3 = r + 2/3-2/3

3/8 - 2/3 = r

Get a common denominator or 24

3/8 *3/3    - 2/3 *8/8    =r

9/24   - 16/24   =r

-7/24 = r

Answer:

Step-by-step explanation:

Answer:

3/5 = 0.6

1/8 = 0.125

3/50 = 0.06

7/8 = 87.5%

1/3 = 33 1/3%

hope this helped.. brainliest??

Answer:3/5 = 0.6

1/8 = 0.125

3/50 = 0.06

7/8 = 87.5%

1/3 = 33 1/3%

half a number:  

→10×(x2+?) and 6: → 10 × ( x 2 + 6 )

is 8 : → 10 × ( x 2 + 6 ) = 8

10 ( x 2 + 6 ) = 8

Multiply out the bracket

5 x + 60 = 8 Subtract 60 from both sides 5 x = 58

Divide both sides by 5 x = 58 5

10 times:  Subtract 60 from both sides

5 x = 58 Divide both sides by 5 x = 58 5
