Ten percent is 3 starburst because to find ten percent you divide the total number by ten. now to find 70 percent you times ten percent by seven. 3 x7 = 21 :)
Answer:
60% of $70 is $42, so i think its $42
Step 1
find the inverse
<span>exchange x for y and y for x
y=2x
then
x=2y---------> clear y
y=x/2
</span><span>f−1(x)=x/2
for x=32
</span>f−1(32)=32/2----------> 16
<span>
the answer is 16

Answer:
If there is "p" pounds of peanuts and "m" pounds of '20% peanuts and 80% almonds' mixture, then, we can get the following equations,
p + m = 10 -----------(1) and
4m/5 = 4 ------------(2)
whose solution is 5 lb peanuts and 5 lb mixture.
Step-by-step explanation:
In the mixture which Delaney wants to make there would be
lb
= 6 lb of peanuts
So, there will be (10 - 6) lb
= 4 lb of almonds
If Delaney has "p" pounds of peanuts and "m" pounds of the '20% peanuts and 80% almonds' mixture, then according to the question,
p + m = 10 -----------(1) and
4m/5 = 4 ------------(2)
So, from (2),
m = 5 --------------(3)
So, from (1) and (3) ,
p = (10 - 5) = 5
