sorry it's sloppy i used windows paint to fill it in but if the probability for heads is 2/7 then the probability for tails is 5/7. Multiply the probabilities for each situation to get answers.
Answer:
Step-by-step explanation:
340/25 = 13.6 = 13 hours and 10 min
30 x 13.6 = 408 hours
25x+30y= 340 and y=2x can be used to determine the number of hours cooper worked and the number of hours isaiah worked. Where x Isaiah 's working hours and y is cooper's working hours.
Step-by-step explanation:
Isaiah ironing rate per hour = 25 shirts
Cooper ironing rate per hour = 30 shirts
Total shirts pressed = 340
Let,
Isaiah´s number of hours = x
Cooper's number of hours = y
According to given statement;
25x+30y=340 Eqn 1
Hudson worked twice many hours as grace.
y = 2x Eqn 2

Answer:
<em><u>x=-6, y=-2</u></em>, (As a point) (-6, -2).....The point form is not necessary unless you want to solve the system (of equations) by graphing.
Step-by-step explanation:
By substitution:
x-y=-4 By adding y on both sides,
x=y-4
Now you can substitute x for the expression (y-4)
Plug the (y-4) as x in the other equation.
So -2x+3y=6 becomes
-2(y-4)+3y=6
Now solve:
-2(y-4)+3y=6 distributes out to be
-2y+8+3y=6 Now combining like terms
y+8=6 Subtract 8 on both sides to isolate the variable
<u><em>y=-2</em></u>
Now plug the value -2 in where the y is in any equation (preferably the easier/less complicated one) and solve for x.
So x-y=-4 becomes
x-(-2)=-4
=x+2=-4
=<u><em>x=-6</em></u>
Answer:
its 15 lol
this is elementary school or something???
Step-by-step explanation:
IF
3 * x =9
then do 9/3=3
So you are multiplying by 3
So therefore you would do that to 5 so its 9/15
and 9/15 and 3/5 are the same, just that 9/15 isnt simplified
hope this helps have a nice day!!
