Answer:
m = $6.5
s = $3
Step-by-step explanation:
Raul ordered 1 small photo enlargement and 4 medium photo enlargements for $29. Patricia ordered 5 small photo enlargements and 2 medium photo enlargments for $28. determine the price of the small photo enlargements and medium photo enlargments
two equations can be derived from the question
s + 4m = 29 equation 1
5s + 2m = 28 equation 2
where
s = small photo enlargements
m = medium photo enlargements
multiply equation 1 by 5
5s + 20m = 145 equation 3
subtract equation 2 from 3
18m = 117
m = 6.5
substitute for m in equation 1
s = 29 - (4 x 6.5)
s = 3
Answer:
A)25
B) 14
Step-by-step explanation:
A) a/5 + 3 = 8
a/5 = 8 - 3
a = 5 x 5
a = 25
B) 3b/7 -1 =5
3b/7 = 5+1
3b = 6 x 7
b = 42/3
b = 14
(3x-5)(3x+1) is the answer
Answer:
48
Step-by-step explanation:
First, get a total of the ration so 3+4=7
Then 112/7=16
So there is 16 times he puts 3 ounces of red and 4 ounces of blue.
3x16 = 48 (red)
4x16 = 64 (blue)
4+48=112

Exercise Problem Solution
1 Find the perimeter of a triangle the sides of which are 10 in, 14 in and 15 in. P = 10 in + 14 in + 15 in = 39 in
2 A rectangle has a length of 12 cm and a width of 4 cm. Find its perimeter. P = 12 cm + 12 cm + 4 cm + 4 cm = 32 cm
3 Find the perimeter of a regular hexagon with each side measuring 8 m. P = 6(8 m) = 48 m
4 The perimeter of a square is 20 ft. How long is one side? 20 ft ÷ 4 = 5 ft
5 The perimeter of a regular pentagon is 100 cm. How long is one side? 100 cm ÷ 5 = 20 cm
