Answer:
The cost of one brownie is $0.75
Step-by-step explanation:
The given parameters are;
The number of pizza's Marcel bought = 4 pieces
The number of brownies Marcel bought = 2 brownies
The amount Marcel paid = $18.50
The number of pizza's Morgan bought = 3 pieces
The number of brownies Morgan bought = 2 brownies
The amount Morgan paid = $14.25
Let x represent the cost of a pizza and y represent the cost of a brownie, we have;
4·x + 2·y = $18.50...(1)
3·x + 2·y = $14.25...(2)
Subtracting equation (1) from equation (2) gives;
4·x + 2·y - (3·x + 2·y) = $18.50 - $14.25 = $4.25
4·x - 3·x + 2·y - 2·y = $4.25
x = $4.25
The cost of a pizza = x = $4.25
4·x + 2·y = $18.50
2·y = $18.50 - 4·x = $18.50 - 4×$4.25 = $1.5
y = $1.5/2 = $0.75
y = $0.75
The cost of a brownie = $0.75
ANSWER
Left
EXPLANATION
The given function is
g(x)=f(x+1)
This means that the base function is:
f(x).
The translation f(x+k) will shift the graph to left by k units while f(x-k) will shift the graph to right by k units
Therefore if g(x)=f(x+1) translates the function f(x) 1 unit left.
Answer: left
Answer:
Step-by-step explanation:
a) The maximum weight M that can be supported by a beam is jointly proportional to its width w and the square of its height h, and inversely proportional to its length L. If k represent the constant of proportionality, the expression would be
M = kwh²/L
b) if w = 4 inches, h = 6 inches, length = 12 ft
1 foot = 12 inches
12 ft = 12 × 12 = 144 inches. Therefore
L = 144 inches
M = 4800lb
Substituting these values into
M = kwh²/L, it becomes
4800 = (k × 4 × 6²)/144
4800 = k
The equation becomes
M = 4800wh²/L
c) if L = 10ft(10 × 12 = 120 inches),
h = 10 inches
w = 3 inches, then
M = 4800 × 3 × 10²/120
M = 12000 lbs
Answer:
4 1/2 servings
Step-by-step explanation:
3 ÷ 2/3 = 3 x 3/2 which is 9/2 or 4 1/2 servings
Answer:
no x = -8/13
Step-by-step explanation:
6x – (3x + 8) = 16x
Combine like terms
6x -3x -8 = 16
3x-8 = 16
Subtract 3x from each side
3x-8-3x = 16-3x
-8 = 13x
Divide by 13
-8/13 = 13x/13
-8/13 =x
