X=1 or its 10x=10x because you have to add the two 5x's together first the you get 10=10x then divide both sides by 10 you have x=

Ciara Larry and jeeta pick apples at an orchard Ciara pick twice as many pounds is Larry and three times as many pounds as jeeta

steposvetlana [31]

Answer:

The pounds of apples picked by Ciara was 4,560

The pounds of apples picked by Larry was 2,280

The pounds of apples picked by Jeeta was 1,520

Step-by-step explanation:

Let

x -----> pounds of apples picked by Ciara

y ----> pounds of apples picked by Larry

z ----> pounds of apples picked by Jeeta

we know that

$x+y+z=8,360$ ----> equation A

$x=2y$

$y=x/2$ ----> equation B

$x=3z$

$z=x/3$ ----> equation C

substitute equation B and equation C in equation A and solve for x

$x+x/2+x/3=8,360$

Multiply by 6 both sides to remove the fractions

$6x+3x+2x=50,160$

$11x=50,160$

$x=4,560\ lb$

<em>Find the value of y</em>

$y=x/2$ ----> $y=4,560/2=2,280/ lb$

<em>Find the value of z</em>

$z=x/3$ ---> $z=4,560/3=1,520\ lb$

therefore

The pounds of apples picked by Ciara was 4,560

The pounds of apples picked by Larry was 2,280

The pounds of apples picked by Jeeta was 1,520

There are 3 red chips and 2 blue chips. If they form a certain color pattern when arranged in a row, for example RBRRB, how many

svp [43]

Answer:

Option A - 10

Step-by-step explanation:

Given : There are 3 red chips and 2 blue chips. If they form a certain color pattern when arranged in a row, for example RBRRB.

To find : How many color patterns are possible?

Solution :

Total number of chips = 5

So, 5 chips can be arranged in 5! ways.

There are 3 red chips and 2 blue chips.

So, choosing 3 red chips in 3! ways

and choosing 2 blue chips in 2! ways.

As changing the places of similar chip will not create new pattern.

The total pattern is given by,

$T=\frac{5!}{3!\times 2!}$

$T=\frac{5\times 4\times 3!}{3!\times 2}$

$T=10$

Therefore, color patterns are possible are 10.

Option A is correct.

avanturin [10]

We add them up to find the total distance :

$\dfrac{4}{10} + \dfrac{4}{10} = \dfrac{8}{10} = \dfrac{4 \times 2}{5 \times 2} = \dfrac{4}{5}$

$\text {She walked } \dfrac{4}{5} \text { miles}$

A car with 15 gallons of gasoline drives 420 miles until the tank is empty. Write a linear equation that describes the amount of

storchak [24]

Answer:

$y = -\dfrac{1}{28}x + 15$

Step-by-step explanation:

The car uses 15 gallons of gasoline to drive 420 miles.

(15 gal)/(420 mi) = 1/28 gal/mi

The car uses 1/28 gallon of gasoline per mile.

y = mx + b

When x = 0, at the start of the drive, the car has 15 gallons of gasoline.

y = mx + 15

Then for every mile it travels, the amount of gasoline goes down by 1/28 gal. For x miles of travel, it uses 1/28 * x gallons of gasoline.

$y = -\dfrac{1}{28}x + 15$
