Ex 1
the number from 1 to 100, I'll call it x

= (((x + 11) * 6 - 3) / 3 + 5) / 2 - x
= ((6x + 66 - 3) / 3 + 5) / 2 - x
= ((6x + 63) / 3 + 5) / 2 - x
= (2x + 21 + 5) / 2 - x
= (2x + 26) / 2 - x
= x + 13 - x
= 13
finally geez

Ex 2
theres 16 teams.
after a team that loses twice they're out.
1 should be left, therefor 15 teams should be out.
15 * 2 = 30,
there should be 30 or 31 games if the last team alive lost 1 game.

Olivia family drove to Disney land For spring break. Her mom and dad shared the driving duties for a total of 14 hours. her mom

Kay [80]

Mom drove for 11 hours.

Dad drove for 3 hours.

Step-by-step explanation:

Total hours = 14 hours

Total distance = 895 miles

Mom drove a speed of 65 mph

Dad drove a speed of 60 mph

Let 'x' be the number of hours drove by mom.

Let 'y' be the number of hours drove by dad.

x + y = 14 ---------------(1)

65x + 60y = 895 ---------(2)

Multiply eq(1) by 60 and subtract eq(2) from (1),

60x + 60y = 840

-(65x + 60y = 895)

-5x = -55

x = 55/5

x = 11

∴ Mom drove for 11 hours.

Substitute x=11 in eq(1)

11+y = 14

y = 3

∴ Dad drove for 3 hours.

At a clothing store, Ted bought 4 shirts and 2 ties for a total price of $95. At the same store, Stephen bought 3 shirts and 3 t

zepelin [54]

Answer:

$19.50

Step-by-step explanation:

We can turn these into equations by making the shirts 's' and the ties 't'.

4s+2t=95 and 3s+3t=84

Now we can solve the system of equations with substitution.

The table represents a linear function. What is the slope of the function?

TEA [102]

Answer:

-4

Step-by-step explanation:

The function is linear; therefore, the slope of the line joining any two points is the same.

We take any two points from the table and compute the slope or rise/ run between them— let is take points (-4, -2) and (-2, -10).

The slope $m$ of the line joining the points is

$m=\dfrac{\Delta y }{\Delta x } =\dfrac{-2-(-10)}{-4-(-2)} \\\\\boxed{m=-4}$

The slope of the function is -4.
