6 0

Step-by-step explanation:

To get the x-intercept, set y = 0. Then solve for x:

9 {x}^{2}  = 18 \\ x =  \sqrt{2}

Therefore, the x-intercept is

( \sqrt{2}  \:  \:  \:  \: 0)

Aiden and Haisem are going to eat the same amount of hamburgers and fries, but from different restaurants. Aiden goes to Burger
Paha777 [63]

Answer:

the burgers be 3 and fries be 2

Step-by-step explanation:

The computation is shown below:

Let us assume burgers be x

And, the fries be y

Now according to the questiojn

1.25x + 0.50y = $4.75

1.50x + 0.99y = $6.48

Now multiply by 1.2 in the first equation

1.50x + 0.6y = $5.70

1.50x + 0.99y = $6.48

-0.39y = -0.78

y = 2

Now put the value of y in any of the above equation

1.25x + 0.50(2) = $4.75

x = 3

Hence, the burgers be 3 and fries be 2

The perimeter of a triangle is 199 inches. If one side of the triangle is six more than the shorter side, and the longer side is
Keith_Richards [23]
Shortest side (a) = 58
middle side (b) = 64
longest side (c) = 77

the 3 sides a + b + c = 199
b = a + 6
c = a + 19

substitute your new values for b & c into your original formula, so:
a + (a+6) + (a+19) = 199
3a + 25 = 199
3a = 174
a = 58

then substitute 58 into your b & c formulas to figure out the rest
b = a + 6 = 58 + 6 = 64
c = a + 19 = 58 + 19 = 77

stealth61 [152]

Answer:

16 tiles

Step-by-step explanation:

Divide 4 by 1/4 to get your answer.

This is the same as multiplying 4 by the inverse of 1/4 (which is 4/1 a.k.a 4)

4 * 4 = 16

16 tiles will fit end-to-end along a 4-foot wall.
