frez [133]

Answer:

The number of hamburgers sold with cheese was 165 and the number of hamburgers sold without cheese was 330

Step-by-step explanation:

The correct question is

Birds burgers barn sold 495 hamburgers today. The number sold with cheese wise half the number sold without cheese. How many of each kind were sold?

Let

x -----> the number of hamburgers sold with cheese

y -----> the number of hamburgers sold without cheese

we know that

$x+y=495$ -----> equation A

$x=\frac{1}{2}y$ ----> equation B

substitute the equation B in equation A and solve for y

$y+\frac{1}{2}y=495$

$\frac{3}{2}y=495$

$y=495(2)/3$

$y=330$

Find the value of x

$x=\frac{1}{2}330=165$

therefore

The number of hamburgers sold with cheese was 165 and the number of hamburgers sold without cheese was 330

Please please need help on these two

kati45 [8]

Answer:

( f + g ) (x) = $2 x^{2} + x - 4$

g(x) - f(x) = $x^{2} - 2 x - 4$

Step-by-step explanation:

f(x) = 4 x - 4 and g(x) = $2 x^{2} - 3 x$

( f + g ) (x) = f(x) + g(x)

= $4 x - 4 + 2 x^{2} - 2 x$

= $2 x^{2} + x -4$

2. g(x) = $x^{2} + 1$ and f(x) = 2 x + 5

g(x) - f(x) = $x^{2} + 1 - (2 x + 5)$

= $x^{2} + 1 - 2 x - 5$

= $x^{2} - 2 x - 4$

Y varies inversely with x. If y = 40 when x = 16, find x when y =-5.

AfilCa [17]

Y varies directly with x m eans
y=kx where k is constant

y=40
x=16
find k
40=k16
divide both sides by 16
5/2=k

y=5/2x

y=-5 find x
-5=5/2x
times 2/5 both sides to cancle fraciton (5/2 times 2/5=10/10=1)
-10/5=x
-2=x

x=-2
