Answer:
Step-by-step explanation:
4s + 2j = 68........2j = -4s + 68........j = -2s + 34
3s + 3j = 81
3s + 3(-2s + 34) = 81
3s - 6s + 102 = 81
3s - 6s = 81 - 102
-3s = - 21
s = -21/-3
s = 7 <==== shirts cost 7 bucks
j = -2s + 34
j = -2(7) + 34
j = -14 + 34
j = 20 <===== jeans cost 20 bucks
the percent increase in the price of a gallon of milk from 1985 to 2005 is 59%
Define percent increase
Percent increase can be described as the rise in the value of an item, in this case the value is milk.
Write out the parameters
In 1985 the price of a gallon of milk is $2.20
In 2005 the price is $3.50
Formula for percent increase
new price-old price/new price × 100
Calculate the percent increase
new price= $3.50
old price= $2.20
= 3.50-2.20/2.20
= 1.3/2.20
= 0.59 × 100
= 59%
Hence the percent increase from 1985 t0 2005 is 59%

Answer:
30 cm
Step-by-step explanation:
To find the perimeter of the rectangle, you first need to find the width and length of the rectangle:
54/9 = 6
L = 9
W = 6
The perimeter is 2lw:
The answer is 30 cm
A = LW
A = (< = 33)
L = W + 8
W(W + 8) < = 33
W^2 + 8W < = 33
W^2 + 8W - 33 < = 0
(W + 11)(W - 3) < = 0
W + 11 < = 0
W < = -11 (extraneous solution)
W - 3 < = 0
W < = 3 <===
L < = W + 8
L < = 3 + 8
L < = 11 <===
A) 5x⁴-8 <----- the tell-tale guy is the exponent of the variable, is 4, so the degree is 4, 5x then minus then 8, two terms, a BInomial
b) 4a²-2a-16 <---- same tell-tale guy, a² has a higher exponent than say "a", so, the degree is the higher exponent, degree of 2
it has 3 terms, thus is a TRInomial
c) 9m³ <---- well, is the only term, variable exponent is 3, so, degree of 3
only one term means is a MONOmial.
