Answer:
Step-by-step explanation:
7h+3s=27.95 subtract 7h from both sides
3s=27.95-7h divide both sides by 3
s=(27.95-7h)/3
Then we are told:
5h+4s=23.4, using s found above makes this equation become:
5h+4(27.95-7h)/3=23.4 multiply both sides by 3
15h+4(27.95-7h=70.2 perform indicated multiplication on left side
15h+111.8-28h=70.2 combine like terms on left side
-13h+111.8=70.2 subtract 111.8 from both sides
-13h=-41.6 divide both sides by -13
h=$3.20
The formula that represents l in terms of f and w is l = (f-5w)/2
<h3>Subject of formula </h3>
This is way of representing a variable with other variables in an expression, Given the expression that represent the amount of fence a farmer needs to create a garden with width w and length
f = 5w + 2l
Make l the subject of the formula
2l = f - 5w
Divide both sides by 2
2l/2 = (f-5w)/2
l = (f-5w)/2
Hence the formula that represents l in terms of f and w is l = (f-5w)/2
