what is 15+3(2x-4)-4x can you help please

The bat weighs 10kg.

Two equations can be gotten from the question:

5a + 4b = 58 equation 1

4a + 5b = 50 equation 2

Where:

a = weight of bats

b = weight of balls

The two equations are simultaneous equations and would be solved using the elimination method.

In order to determine the weight of balls, take the following steps:

Multiply equation 1 by 4 and equation 2 by 5

20a + 16b = 232 equation 3

20a + 25b = 250 equation 4

Subtract equation 3 from 4

18 = 9b

Divide both sides of the equation by 9

b = 2kg

In order to determine the weight of bats, take the following steps:

Replace for b in equation 1

5a + 4(2) = 58

5a + 8 = 58

5a = 58 - 8

5a = 50

Divide both sides of the equation by 5

a = 10kg

Answer:

a = 17 / 11

Step-by-step explanation:

or, a - 2 = 3(3 + 6a)

or, a - 2 = 9 + 18a

or, - 2 - 9 = 18a - a

or, -11 = 17a

or, a = 17 / 11

Step-by-step explanation:

Given that 15 food booths were rented out for ‘d’ days at $100 plus $5 per day. On the food booths only, the company will earn 15($100+$5d) = $1500 + $75d Given that 20 game booths were rented out for ‘d’ days at $50 plus $7 per day. On the game booths only, the company will earn 20($50 + $7d) = $1000 + $140d

The total amount that the company is paid is therefore, $1500 + $75d + $1000 + $140d = $2500 + $215d

I believe your answer is 2/10,3/10,4/10,5/10,6/10,7/10.

4/5 can be converted to 8/10 by multiplying the denominator and the numerator by 2 so the new numbers are 1/10 and 8/10 the numbers that are between that are 2/10,3/10,4/10,5/10,6/10,7/10.

The best explanation to given when checking for the value of g that you have found is:

C.  Substitute the value for g on either sides of your equation to check the answer. If the check does not​ work, it is either the answer is incorrect or there were errors you made when checking.

After solving for a variable in an equation, we can cross check to know if our answer is correct or not.

This can be done by plugging in or substituting the value of the variable g into the equation. In most cases, you will find the variable on both sides.

When you substitute, the value on the left must be equal to the value on the right. If during your check, the value on the left does not equal the value on the right, it simply means the check does not work.

Two things might result to a check not working:

Therefore, the best explanation to given when checking for the value of g that you have found is:

C.  Substitute the value for g on either sides of your equation to check the answer. If the check does not​ work, it is either the answer is incorrect or there were errors you made when checking.

Answer:

The expression p−0.45p can be simplified to  0.55 p.

This means Phyllis can find the new price of a hat by finding  55 % of the original price.

Step-by-step explanation:

The given expression describes that the price of the Hat would be 55% of the original price.

Given that,
Hats are on sale for 45% off. Phyllis uses the expression p−0.45p to find the new price of a hat that originally cost p dollars.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
Given expression,
= p−0.45p
Simplify further,
= 0.55p
The above expression implies that the outcome is 55% of p, where p is the original price of the Hats.

Thus, the given expression describes that the price of the Hat would be 55% of the original price.

A = L x W

A = 3 3/4 x 1 1/2

A = (you do the math, 3 3/4 x 1 1/2 : )

Step-by-step explanation:

Hope this helps! Please gie brainliest

Answer:

The formula to find the AREA of a rectangle is as shown A=l x w

L meaning Lenght, which in this case is 3 [tex]\frac{3}{4}[/tex] ft.

W meaning width, which in this case is 1 [tex]\frac{1}{2}[/tex] ft.

Now that you know what the length and the width are, you want to multiply them like the formula A = l x w

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

You want to create the fractions into a mixed number.

3 3/4 = 15/4

1 1/2 = 3/2

Now when you multiply it should look like this :

[tex]\frac{15*3 }{4*2}[/tex]  or 15x3 / 4x2

This will get you the mixed number of 45/8

Then you can covert the mixed number to a whole number which will be

5 5/8

This will get you the final answer of 5 [tex]\frac{5}{8}[/tex] ft. This is your area.

we first substitute the x

y= -2(-2-1)

=6

and then use a calculator to do the sum

which gives us 6

y= -2(-1-1)

= 4

y= -2(0-1)

=2

y= -2(1-1)

=0

y= -2(2-1)

=-2
