First combine 4+6 to equal an easy 10.....then combine 8+2 to make another easy 10.....then add 28+1+1 to equal an even 30.....so what you have left is 4+5+9+9202.....so combine 4+5 to make 9 and add 9 (9+9).....so now you have 18+9202.....so 8 goes into 2 evenly, carry the 1, 1+0 is 1, then just 92, so 9210.....so now add all of your totals, 10+10+30+9210, 10+10=20 so add 20 to 30 to get 50 and add 50 to 9210.....so your total is 9260!
the cost for each of jelly beans and each pound of trail mix is $2.5 and $1.75
<u>Step-by-step explanation:</u>
Given A store is having a sale on jelly beans and trail mix. For 3 pounds of jelly beans and 2 pounds of trail mix, the total cost is $11. For 5 pounds of jelly beans and 6 pounds of trail mix, the total cost is $23 . We have to find the cost for each pound of trail mix and each pound of jelly beans.
Let the cost of each pound of trail mix is $y.
and the cost of each pound of jelly beans is $x.
According to question,
For 3 pounds of jelly beans and 2 pounds of trail mix, the total cost is $11.
⇒ → (1)
For 5 pounds of jelly beans and 6 pounds of trail mix, the total cost is $23
⇒ → (2)
Solving (1) and (2), we get
3(1 equation)-(2 equation)=0
⇒
⇒
hence,
⇒
⇒
Putting in we get ;
⇒
⇒
⇒
⇒
Hence, the cost for each of jelly beans and each pound of trail mix is $2.5 and $1.75 .
If you would like to solve 1/3 / 6, you can do this using the following steps:
1/3 / 6 = 1/3 / 6/1 = 1/3 * 1/6 = 1/18
The correct result would be 1/18.
Answer:
50.5
Step-by-step explanation:
2xy+2x^2 And we know x=-2.5 and y=-7.5.
In order of operations, exponents come first.
x^2 = -2.5 * -2.5 = 6.5.
6.5*2=13.
2xy + 13
2x=-5
-5*-7.5 = 37.5
37.5 + 13
50.5
