Jared is 10 years old and Peter is 15 years old. Together they run 150 yards. How far does each brother run?

Answers

Answer 1
Answer:

Jared runs 60 yards and Peter runs 90 yards if Jared is 10 years old and Peter is 15 years old. Together they run 150 yards.

What is the ratio?

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

It is given that:

Jared is 10 years old and Peter is 15 years old. Together they run 150 yards.

The ratio of their ages:

= 10/15

= 2/3

Let x be the common number:

2x + 3x = 150

5x = 150

x = 30

2x = 2(30) = 60 yards

3x = 3(30) = 90 yards

Thus, Jared runs 60 yards and Peter runs 90 yards if Jared is 10 years old and Peter is 15 years old. Together they run 150 yards.

The complete question is:

The distance of each boy depends on the ratio of their ages.

Jared is 10 years old and Peter is 15 years old. Together they run 150 yards. How far does each brother run?

Answer 2
Answer:
It's not possible to answer that question with the information
you have given us.  We don't know if there is any connection
between each boy's age and the distance he runs.  If there IS
a connection, we don't know what it is or how it works.

Yes,this is a doozy.

                 -3 (y - 5)  =  15

Eliminate the parentheses on the left side:

                 -3(y) -3(-5)  =  15

                 -3y  + 15  =  15

Subtract 15 from each side: 

                 -3y  =  0

Divide each side by -3 :

                    y  =  0

Fifteen is added to the product of a number and 6. the result is 9. find the number.

How to find the x intercept in slope intercept form

Answers


-- The x-intercept is the point where the line crosses the x-axis.
-- 'Y' is zero at every point on the x-axis. 
-- So  y=0  at the x-intercept.

You say that you have the equation of the line, and it's in
slope/intercept form ?
                                      Y = mx + b
 Great !  

Just set  y=0.   Then you have      mx + b = 0 .
Solve that for 'x' , and you have the x-intercept.

(It turns out to be    x = - b/m .  Always true, and a very handy formula
to remember if you can, and then you always have the x-intercept at
your fingertips whenever you need it.)

What factor makes the number sentence true 7×4 = ?×7

Answers

The answer is 4. According to the commutative property, you can commutate (swap) numbers over and get the same result. However, it only works for addition and multiplication. For instance, x + y = y + x. Or, x * y = y * x. In our example, we have 7 * 4 = ? * 7. Because we already have 7 on the right side of the expression, the missing number will be 4.

Explanation:
_______________________________________________________
x − (0.25)x = 14000 ;  Solve for x.

1x − (0.25)x = (0.75)x ;
 
(0.75)x = 14000 ; 

Divide each side by: "(0.75)" ;
_______________________________
 x = 14000/(0.75) ;

 x = 18666.6666666666666667
