If James have 8,000 buttons, and he give 4,000 to 3 friends, how many does he have left?

Answers

he would’ve had 4,000

After giving buttons to his friends, James have left with 4000 buttons.

Given that James has 8000 buttons he distributed 4000 buttons to his friends, we need to find how much he have now,

If James originally has 8,000 buttons and he gives 4,000 buttons to three friends, we can calculate the number of buttons he has left by subtracting the buttons given away from the original number.

Buttons James has left = Original number of buttons - Buttons given away

Buttons James has left = 8,000 - 4,000

Buttons James has left = 4,000

Based on the calculations, it seems that James would have 4,000 buttons left.

Answers

Answer:

No, Trey is not correct.

Step-by-step explanation:

3^4 = 3 • 3 • 3 • 3 = 81

4^3 = 4 • 4 • 4 = 64

81 is not equal to 64, so 3^4 is not equal to 4^3.

So basically this problem is asking if exponents can use the commutative property. The commutative property basically tells us that in addition and multiplication numbers can be switched to make it easier for us to solve. That doesn’t go for exponents though. 3 to the 4th power would be 81 and 4 to the 3rd power would be 64. So basically you can only use the commutative property in addition or multiplication problems. Not exponents, subtraction, or division. I hope I explained it well.

Jalissa's mom purchased coffee from the local coffee shop. The first cup of coffee was $4.15. Each refill is $1.25. She also decided to get a bagel for $3.50. If Jalissa's mom had 2 refills and a $0.50 discount as part of the rewards program, how much did she spend at the coffee shop?

Answers

Answer is $9.65
1.25 x 2 = 2.50
4.15 + 3.50 = 7.65
7.65 + 2.50 = 10.15
10.15 - 0.50 = 9.65

Answer:

$9.65

Step-by-step explanation:

1.25 * 2 = 2.5 + 4.15 + 3.5 - 0.5 = $9.65

BTW this is FLVS
HELPPPPPPP

Answers

Answer:

Person above is correct

Step-by-step explanation:

-26 =2(3p-5

The solution is Option C.

The equation -26 = 2( 3p - 5 ) does not satisfy when p = 4

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the solution set be S = { 4 }

a)

Let the equation be A

The value of A is

A = one fourth times x plus 17 equals 18

Substituting the values in the equation , we get

( 1/4 )x + 17 = 18

Now , when x = 4

( 1/4 )4 + 17 = 18

1 + 17 = 18

18 = 18

Therefore , the equation is true

b)

Let the equation be A

The value of A is

5 = 4y - 11

when y = 4

Substituting the values in the equation , we get

5 = 4 ( 4 ) - 11

5 = 16 - 11

5 = 5

Therefore , the equation is true

c)

Let the equation be A

The value of A is

-26 = 2( 3p - 5 )

when p = 4

Substituting the values in the equation , we get

-26 = 2 ( 3 (4) - 5 )

-26 = 2 ( 12 - 5 )

-26 = 2 ( 7 )

-26 ≠ 14

Therefore , the equation is false

d)

Let the equation be A

The value of A is

3 ( b + 4 ) = 24

when b = 4

Substituting the values in the equation , we get

3 ( 4 + 4 ) = 24

3 ( 8 ) = 24

24 = 24

Therefore , the equation is true

Hence , the equation -26 = 2( 3p - 5 ) is false
