Let
x--------------> the third stone measure
we know that
the recommended height for the bench is ------> 20 in
20=[4 3/8]+[4 1/2]+[5 1/4]+[x]
4 3/8---------> (4*8+3)/8=35/8
4 1/2---------> (4*2+1)/2=9/2
5 1/4---------> (5*4+1)/4=21/4
20=[35/8]+[9/2]+[21/4]+[x]
<span>x=20-(35/8)-(9/2)-(21/4)</span>
x=20-(35+4*9+2*21)/8----->
20-113/8------- > (8*20-113)/8
x=47/8----------
> 5.875=5 7/8
<span>
<span>the
answer is 5 7/8 in</span></span>
Answer:
-2/5
Step-by-step explanation:
2x - 11 = 4x - 13 - 7x
2x - 11 = -3x - 13
2x - 11 + 3x = -13
5x - 11 = -13
5x=-13+11
5x=-2
X= - 2/5
To find the price per spoon of brand A, divide the cost by the amount of spoons:
1.99 / 25 = 0.0796
Repeat this process for brand B:
3.89 / 42 = 0.0926
Brand A, at $0.08 a unit, is the better buy of brands A and B.
Hope this helps.
No factors are for multiplication and divisors are for division i think
