A proportional relationship is just a linear relationship where b = 0, or to put it another way, where the line passes through the origin (0,0).

Given the equation p = s Subscript 1 Baseline t minus 2 Subscript 2 Baseline t, which equation is solved for t? t = p (s Subscri

gulaghasi [49]

Answer:

Option C) is correct

That is t=StartFraction p Over s Subscript 1 Baseline minus s Subscript 2 Baseline EndFraction

It also can be written as $t=\frac{p}{s_{1}-s_{2}}$

Step-by-step explanation:

Given equation can be written as below:

$p=s_{1}t-s_{2}t$

Now to solve the equation for t:

$p=s_{1}t-s_{2}t$

Taking common term t outside on RHS we get

$p=(s_{1}-s_{2})t$

$\frac{p}{s_{1}-s_{2}}=t$

Rewritting the above equation as below

$t=\frac{p}{s_{1}-s_{2}}$

Therefore option C) is correct

That is t=StartFraction p Over s Subscript 1 Baseline minus s Subscript 2 Baseline EndFraction

It also can be written as $t=\frac{p}{s_{1}-s_{2}}$

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.
