Answer:
The price of hot dog is $2.5 and that of a pretzel is $1.25.
Step-by-step explanation:
Let the cost of hotdogs be x and that of pretzels be x.
So,
4x+3y = 13.75 ...(1)
and
2x+5y = 11.25 ...(2)
Multiply equation (2) by 2.
4x+10y = 22.5 ...(3)
Subtract equation (1) from (3).
4x+10y-(4x+3y) = 22.5-13.75
4x+10y-4x-3y = 8.75
7y = 8.75
y = 1.25
Put the value of y in equation (1).
4x+3(1.25) = 13.75
4x+3.75 = 13.75
4x = 13.75-3.75
4x = 10
x = 2.5
So, the price of hot dog is $2.5 and that of a pretzel is $1.25.
The cost to mail a package is $7 for the first 2 pounds and 30 cents for each additional ounce.
Which of the following functions represents the cost to mail a package if x is the number of ounces over 2 pounds?
ƒ(x ) = 7 + 0.3x
ƒ(x ) = 14 + 0.3x
ƒ(x ) = 0.3(x + 2)
Answer:
the first one
Step-by-step explanation:
The cost to mail a 2-lb package is $7.
The cost to mail a 2-lb, 1 oz package is $7+$0.30(1).
That to mail a 2-lb, 2 oz package is $7+$0.30(2) = $7.60.
Following this pattern, the general formula is f(x) = $7 + $0.30x, where x represents the number of ounces OVER 2 lb.

Answer:
(B)
b + t = 15
2b + 3t = 45
Step-by-step explanation:
Bicycles and tricycles are represented by the letters b and t respectively.
total no of bicycles and tricycles = 15
So,
b + t = 15
Each bicycle has 2 wheels and each tricycle has three wheels.
So,
No of wheels in b bicycles = 2b
No of wheels in t tricycles = 3t
Total no of wheels = 45
So,
2b + 3t = 45

Factor completely:
5s4 + 20s3 - 40s
Answer:
5s(s3 + 4s2 - 8)
Step-by-step explanation:
Greatest common denominator is 5s
divide all the terms by 5s
5s4 / 5s = s3
20s3/5s = 4s2
-40s/5s = -8

through: (4, -3), perp. to y=-2x + 1
A. Y=1/2x-1/2
B. Y=-1/2x-5
C. Y=1/2x-5
D. Y=-5x-1/2
PLEASE HURRY
Step-by-step explanation:
y = -2x + 1. => Slope = -2
Then the perpendicular line will have a slope of -1/(-2) = 0.5.
We have y = 0.5x + c.
When x = 4, y = -3.
=> (-3) = 0.5(4) + c, c = -5.
Hence the answer is y = 0.5x - 5. (C)

-2/17x=10 what is the solution set?
Answer:
x=-85
Step-by-step explanation:
what is the solution of this system of Linear equations? y=3×-2 and y-2=×
Answer:
(2, 4)
Step-by-step explanation:
Given the system of equations
y=3×-2.... 1
y-2=× ... 2
Substitute 2 into 1
y = 3(y-2) - 2
y = 3y - 6 - 2
y - 3y =-6-2
-2y = -8
y = -8/-2
y = 4
Recall that
x = y - 2
x = 4-2
x = 2
Hence the solution (x, y) is (2,4)
