Step-by-step explanation:
1/4*x + 1/8*x + 1/4 * x = 4 cups
5/8 * x = 4 cups Multiply both sides by 8/5
5/8 * 8/5 x = 4 8/5
x = 32/5
x = 6.4
That means that each ingredient must be multiplied by 6.4
1/4 * 6.4 = 1.6 cups lemon juice
1/8 * 6.4 = .8 cups mustard
1/4 * 6.4 = 1.6 cups vinegar
Total = 4 cups.
Answer:
(-5, -2)
Step-by-step explanation:
3x+4y=-23
x=3y+1
since we have what x is, we need to subsitute
3( 3y+1) + 4y= -23
no we need to multiply the number inside the parenthesis by 3
9y + 3 + 4y= -23
combine like terms ( add the numbers or variables that look alike)
9y+4y is 13y
13y+3= -23
since we need to get the y alone we need to subtract 3 on both sides since its the opposite of adding
13y+3-3=-23-3
13y= -26
now we divide 13 on both sides to get Y alone
13y/13= -26/13
y= -2
now since we have y we need to substitute it to find x
x= 3y+1
x= 3( -2) +1
now we mutliply 3 with -2
x= -6 +1
x=-5
those are ur answers
y= -2
x= -5
hope this helped:D

Answer:
The revenue function
R(x) = - 2x² +490x +2500
Step-by-step explanation:
<u><em>Explanation:-</em></u>
The demand d for a company’s product at cost x is predicted by the function d(x) = 500 – 2x
The price p in dollars that the company can charge for the product is given by p(x) = x + 5
Revenue = price × demand
Revenue = p(x) × d(x)
Revenue = (x+5) ×(500-2x)
Revenue = x(500-2x)+5(500-2x)
Revenue = 500x - 2x² + 2500- 10x
Revenue = - 2x² +490x +2500
The volume of cylindrical soup can is 33.21 cube inches.
Step-by-step explanation:
Radius of soup can = 1.5 in
Height of soup can = 4.7
Volume of soup can = πr²h
