Someone drove 20 miles in 24 minutes at this rate how many miles did they drive in 6 minutes

nikklg [1K]

Distance = rate * time (I will abbreviate as d = rt)
d = rt, so r = d/t
r = 20mi/24min
= 0.833333 mi/min.

d = rt again for the new time
d = 0.8333333 mi/min * 6 min = 5 miles

A football team received 3 penalties for 15 yards each, 1 for5 yards, and1 for half the distance to the goal from the 34- yard l

Effectus [21]

The first penalty they received is three 15 yards so total yards is 3(15 yards)
the second penalty is one 5 yard
the last penalty is half the 34 yard line(34 yard)/2
total change = 3(15 yards) + 5 yrad + (34 yard)/2
= 45 yards + 5 yards + 17 yards= 67yards

Answer:

The expression of the area of rectangle ABCD as simplified polynomial will be:

$A=16x^2-8x$

Hence, the 2nd option is correct.

Step-by-step explanation:

As we know that the area of a rectangle can be obtained by multiplying the length by the width.

i.e.

$A=l\times w$

Given

The length of a rectangle ABCD = $l$ = $(x+5) + (3x) + (4x-9)$

The width of a rectangle = $w$ = $2x$

so the expression of the area of rectangle ABCD as simplified polynomial will be:

$A=l\times w$

$A=\left[\left(x+5\right)\:+\:\left(3x\right)\:+\:\left(4x-9\right)\right]\:\times \left[2x\right]$

$=\left(\left(x+5\right)+\left(3x\right)+\left(4x-9\right)\right)\left(2x\right)$

$=\left(x+5+3x+4x-9\right)\times \:2x$

$=2x\left(8x-4\right)$

$=16x^2-8x$

Therefore, the expression of the area of rectangle ABCD as simplified polynomial will be:

$A=16x^2-8x$

Hence, the 2nd option is correct.

How do we do Systems of Equation and then how do we label it as one solution, no solution, or infinitely many solutions.

RoseWind [281]

To solve Systems of Equations you can use graphing, substitution, or by adding, subtraction, multiplying, or division methods. One solution is consistent and dependent. No solution is inconsistent. Infinitely many solutions is consistent and dependent.
