Answer:

Ishaan is 49 years old.

Step-by-step explanation:

Let the present age of Christopher be 'C'.

Let the present age of Ishaan be 'I'.

From the given data, we can form equations which will help us solve the problem.

Christopher is 20 years younger than Ishaan. This means:

C = I - 20                  . . . (1)

Fourteen years ago, Ishaan would have been (I -14) years old and Christopher (C - 14) years old.

From the data, I - 14 = 3(C - 14)         . . . (2)

Substituting the value of C in Equation 2, we get:

I - 14 = 3(I - 20 - 14)

⇒ I - 14 = 3(I - 34)

⇒ I - 14 = 3I - 112

⇒ 2I = 112 + 14 = 98

⇒ I = 49

So, Ishaan is 49 years old.

A store is having a sale on trail mix and jelly beans. For 5 pounds of trail mix and 3 pounds of jelly beans, the total cost is
GaryK [48]

Answer:

Trail Mix costs $2.50 per pound, and Jelly Beans cost $1.50 per pound.

Step-by-step explanation:

Using x for trail mix and y for jelly beans, we have a system of equations being

\left \{ {{5x+3y=17} \atop {2x+12y=23}} \right.

We can solve this system using substitution

5x+3y=17

Divide by 5 to have a coefficient of 1 before x

x+\frac{3}{5} y=\frac{17}{5}

Subtract \frac{3}{5} y from each side to single out one variable to one side

x=\frac{17}{5} -\frac{3}{5} y

Now, we can plug in our value for x into the given equation

2(\frac{17}{5} -\frac{3}{5} y)+12y=23

Open the parentheses

\frac{34}{5} -1\frac{1}{5} y+12y=23

Merge Y values

6.8+10.8y=23

Separate numerical values from variables

10.8y=16.2

Divide by 10.8 in order to have a coefficient of 1

y=1.5

Now that we have one of the values, we know that a pound of jelly beans costs $1.50. We can now plug in 1.5 for y into one of our equations to find x.

5x+3(1.5)=17

Open parentheses

5x+4.5=17

Single out the variable

5x=12.5

Divide by 5 to have a coefficient of 1 before x

x=2.5

y=1.5
