Answer:

James is 37, Rob is 44, and Kate is 35

Step-by-step explanation:

Set up an equation where x is James' age:

Rob's age can be represented by x + 7, since he is 7 years older than James

Kate's age can be represented by x - 2, since she is 2 years younger than James

Add these together in the equation and set it equal to 116:

(x + 7) + (x - 2) + (x) = 116

Add like terms and solve for x:

(x + 7) + (x - 2) + (x) = 116

3x + 5 = 116

3x = 111

x = 37

So, James is 37.

Find Rob's age by adding 7 to this:

37 + 7

= 44

Find Kate's age by subtracting 2:

37 - 2

= 35

So, James is 37, Rob is 44, and Kate is 35

Answer:

Rob = 44

Kate = 35

James = 37

Step-by-step explanation:

Rob = 44     which is 7 years older than James

Kate = 35     which is 2 years younger than James

James = 37

The total cost for the boots after the sales tax of 5.12% will be $71.48.

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

Emily wants to buy new boots that cost $68. The sales tax rate in her city is 5.12%.

Let x be the total cost for the boots. Then the total cost for the boots will be given as,

x = (1 + 5.12%) × $68

x = (1 + 0.0512) × $68

x = 1.0512 × $68

x = $71.48

The total cost for the boots after the sales tax of 5.12% will be $71.48.

This question is incomplete, the complete question is;

For integers a, b and k, we know that a > 12, b < 20 and a < b. If b=7k, what is the value of k ?

Answer: the value of k = 2

Step-by-step explanation:

Given that;

a > 12

b < 20

a < b

If b = 7k

Now if k = 1      {b = 7k = 7}

b would be equal to 7 but b has to be greater than 20

IT CANT BE

if k = 2        { b = 7k = 14}

b would be equal to 14, a is greater than 12, b has to be less than b; 14 < 20,

a has to be less than than b ( 12 < 14 )

IT IS

if k = 3      {b = 7k = 21}  

b would be equal to 21, so b is greater than 20 and a is less than 21

IT CANT BE

Therefore the value of k = 2

Answer:

  10

Step-by-step explanation:

Let L and T represent the initial amounts that Leo and Theo had. Let n represent the number of bills exchanged in the first exchange. Then we have ...

  L -20n +50n = T -50n +20n . . . . after the first exchange, each has the same

After the second exchange, amounts trade places:

  (L +30n) +6(50) = T

Substituting this into the first equation, we get ...

  L +30n = ((L +30n) +300) -30n

  30n = 300

  n = 10

Leo gave Theo ten $20 bills.

_____

Comment on the amounts

Theo started with $600 more than Leo, including exactly 16 $50 bills. Leo had at least 10 $20 bills, so he could make the initial exchange. Whatever initial amount Leo had in excess of that $200 was matched in Theo's initial amount, but Theo must have had that excess in $20 bills only. For example, Leo may have started with $300 as 10×$20 +2×$50, but Theo's initial $900 would need to be 5×$20 +16×$50.

Answer:hope she/he replies

Step-by-step explanation:

Answer:

She will need 12 1/8 cups of brown rice and 16 1/8 cups of water.

Step-by-step explanation:

You will want to convert 1 1/2 cups into an improper fraction, as well as 2 cups.

1 1/2 = 3/2

2 = 2/1

Now that you have done that you will then have to find a common denominator. You will need to list the multiples for 8 and lowest common factor so you don't have to simplify at the end.

The multiples of 8: 1, 2, 4, and 8

As shown above 2 is a multiple of 8. Therefore you will need to multiply the denominator by 4. This is because 2 x 4 equals 8. So now the denominator is 8. You will now need to multiply the numerator by 4 because that is what you multiplied the bottom by. It will be 3 x 4, and will therefore equal 12. The final improper fraction will be 12/8. The numerator then becomes the answer because that is the amount of 1/8 cups that you will need.

You then repeat this with 2/1. However you will need to multiply the denominator by a different number because it is 1. Looking at the multiples of 8 above, you will multiply the 1 by 8, therefore giving you 8 as the denominator. You will then multiply the numerator by 8 as well. This will result in an answer of 16. You will then have a 16/8. You will need 16 1/8 cups of water.

Answer:

well, x = 5

Step-by-step explanation:

here,

EB Is parallel to DC , so

Angle AEB = Angle ADE

( because they are corresponding angle pair )

Angle ABE = Angle ACD

( because they are corresponding angle pair )

triangle ADC Is similar to triangle AEB

(By AA similarity criteria )

hence AE / ED = AB / BC ( by CPCT )

so 24/10 = 12/x

12. 7

13. 6

Step-by-step explanation:

Answer:   12. x =7           13. x =6

Step-by-step explanation:

Both angles in the triangle has to equal to each other because they are both equivalent.

Set both expressions equal to each other and solve for x.  

12.  5x =  35    Divide both sides by 5

x =  7  

13.     3x =   5x - 12      Subtract 5x from both sides

        -5x       -5x  

   -2x =  -12      Divide both sides by -2

 x = 6

Each bottle holds 1.75 liters of water.

To determine how much water each bottle holds, we can divide the total amount of water by the number of bottles.

Given that 200 bottles hold 350 liters of water, we divide 350 liters by 200 bottles:

350 liters / 200 bottles = 1.75 liters per bottle

Therefore, each bottle holds 1.75 liters of water.Therefore, each bottle holds 1.75 liters of water.

This means that if we were to fill each bottle to its maximum capacity, it would hold 1.75 liters of water.

It's important to note that this assumes each bottle has an equal capacity and that the water is evenly distributed among them.

Answer:

437.999 + 0.001 = 438

Step-by-step explanation:

Answer:

1: y = 3x + 1 Swap sides so that all variable terms are on the left hand side. 3x + 1 = y Subtract 1 from both sides.

2: y(x) = 5x, y(x) is just another way of writing the equation to indicate that y is a function of x. You could simply write it as y = 5x. Thus if we compare to the standard form equation y = ax + b, a=5 and b=0. Thus the y-intercept is zero.
