Answer:
$18.
Step-by-step explanation:
$9:8= 1.125 $ per pound.
16 x 1.125 =18$
Assuming they start saving at 0 dollars
45=total=duanesavings+micksavings
duanesavings=confusing, I will explain
mick savings =amount saves per week times number of weeks
duane saves 5 dollars every other week, aka 2.5 dollars per 1 week
DS=2.5w
MS=2w
since they save at same time and at that week, when the weeks are equal (w=w), 45 it total
DS+MS=45
2.5w+2w=45
4.5w=45
divide by 4.5 both sides
w=10
10 weeks
Answer:
-88
Step-by-step explanation:
If a=2, we can say that - would be -4.
Secondly, if a=2 and b=-6 we can assume that 4ab would become -48.
Finally, if b=-6 we can say that - would become -36.
Adding all of those up gives you -88, your answer.
Answer:
h = 2A/b
Step-by-step explanation:
The given area triangle is denoted by:
A=1/2bh
By solving for "h", we're simply asked to make "h" the subject of the formula, that is putting "h" on one side of the equation and all other variable/values on the other side of the equation.
By doing this, we move other variables presently on the right side with "h" and the left hand side of the equation takes them all except "h", then we have:
2A/b = h.
