The ratio of the ages of three children is 2:4:5. The sum of their ages is 33. What is the age of each child?
sdas [7]
We can represent this situation by the equation 2x+4x+5x=33.

Then 11x=33, and x = 3.  

Then the children's ages are in the ratio 2x:4x:5x, or 2(3):4(3):5(3), or

6:12:15.

Do these 3 ages add up to 33?  6 + 12 + 15 = 33?  YES!

The children's ages are 6, 12 and 15 years respectively.

What is the total cost if the shirt cost $40 and 20% off
Eddi Din [679]
You'd simply have to find 20% of $40. To find the percent of a number, you would change the percent into an actual decimal/number, and then multiply them both. So the percent would become 0.20.

40 × 0.20 = 8

So now you would subtract 8 from the cost of 40.

 40 - 8 = 32.

The shirt costs $32.

Help please ............ solve<br><br>Solve<br><br> <br><br>X-3y=z<br>-x+2y=-3
Alenkasestr [34]
You don't need 3 equations to get a general solution.  To do this use the equations x-3y-z=0 and -x+2y+0z= -3.  Start out by letting z = t.  Then solving those 2 equations simultaneously, your x's cancel out leaving you with -y-z=-3.  But since z=t, then -y=-3+t or y=3-t.  Now sub that in for y in the first equation, along with the fact that z=t to get x-3(3-t)-t = 0 and solve for x. x=9-2t.  So a general solution for this would be (9-2t, 3-t, t)

How am I supposed to do that??
marissa [1.9K]

Answer:

not a solution

Step-by-step explanation:

y = -3/4 x +3

Is (3,2) a solution?

Substitute the point into the equation and see if it  is true

2 = -3/4(3) +3

2 = -9/4 +3

2 = -9/4 +16/4

2 = 7/4

False
