6/2+1= 4
4 is your answer
6/2=3 + 1=4
Answer:
x = - 18
Step-by-step explanation:
Given
- 7 + 
= - 13 ( add 7 to both sides )
= - 6 ( multiply both sides by 3 to clear the fraction )
x = - 18
7.98+4.89+5.12=17.99 so the estimate would be 18.
Now you have
<u />
<u>(.15)0.5 lb peanuts</u> = <u>0.075 lb peanuts</u>
0.5 lb nuts 0.5 lb nuts
for every pound of 75% mixed nuts you add, you get .75 lb peanuts, how many pounds, x, do you need to add to get the ratio 50 to 100?
<u>0.075 lb peanuts + 0.75x lb peanuts</u><em> = <u /></em><u> 50 </u><u>
</u>0.5 lb nuts + x lb nuts 100
cross multiply
(0.075 + .75x) 100 = (0.5 + x) 50
7.5 + 75x = 25 + 50x
25x = 17.5
x = 0.7 lb of 75% peanuts
