Answer:
The line '10x-8=10' should be '10x-8=4x+10'
He took 2x away on the right side , as opposed to adding it.
So
eq=ellen's quarters
en=ellens's nickles
lq=lola's quarters
ln=lola's nickles
lq/2=eq or lq=2(eq)
2(ln)=en or ln=en/2
en+eq=$6.30 or 630 cents
en+6nickles=eq
so nickle=5 so
5*6=30
630-30=600
number of nicles=number of quarters of lola=600
nickle+quater=30
600/30=20
20 quarters
20+6=26 nickles
elen has 20 quarters and 26 nickles
20 times 2=40 quarters
26 divided by 2=13 nickles
lola has 40 quarters and 13 nickles
40 times 25=1000 cents in quarters
13 times 5=65 cents in nickles
1000+65=1065 cents or $10.65=lola's money
The problem is using a right triangle, it means we can use the Pythagorean theorem in solving the problem. We have two possible measurements for the third side.
First length, when the third side is the hypotenuse:
x ² = 15² + 12²
x = 19.21
Second possible length, when the third leg is either an adjacent or base side:
15² = x² + 12²
x = 9
Therefore, the difference between the two possible answers are shown below:
Difference = 19.21 - 9 = 10.21
I think so that both are b
