Answer:
5 five-dollar coins and 3 ten-dollar coins
Step-by-step explanation:
10x3=30
5x5=25
30+25=55
here we plug in values of x in f(x) and g(x)
the table in attachment shows the answer
<span> sqrt(n+5)-sqrt(n-10)=1 </span>One solution was found : <span> n = 59
</span>Radical Equation entered :
<span> √n+5-√n-10 = 1</span>
If it's -4+8, -4 is 4 less than 0. 8 is 8 more than 0, also 4+4. so -4+4 would be zero, then there's 4 more and 0+4 is 4
For this question you have to solve the equation backwards.
A = 1/2 x (b1 + b2) x h
In order to get rid of the 1/2 (since it's division) multiply each side by 2
now we have: 2A = (b1 + b2) x h
Now do the same to the get rid of the (b1 + b2) (divide each side by it)
2A/(b1 + b2) = h
