Answer:

8 hours

Step-by-step explanation:

let number of hours it takes to finish the cup be t,

we know that we have 80 cups, and we know we can finish 10 cups per hour so,

10t = 80 which is 10 times t = 80

Solve for t,

10t/10 = 80/10

t = 8

Answer:

X=20

Step-by-step explanation:

360/18=20

Answer:

x=20

Step-by-step explanation:

18x=360

divide both sides by 18x

[tex]\frac{18x}{18}[/tex]=[tex]\frac{360}{18}[/tex]

simplify

x=20

hope this helps :) have a nice day !!

Answer:

4.5

Step-by-step explanation:

Answer:

5 1/2 or 5.5

Step-by-step explanation:

=8 1/2+2 1/6-5 2/12

=17/2+ 2 1/6-5 2/12

=17/2+13/6-5 2/12

=32/3- 5 2/12

=32/3-31/6

=11/2

=5 1/2

$10.50

Explanation:

Let x be the cost of the individual books. Then 24.81=3x−6.69

3x= 24.81+ 6.69 =31.50

x=31.50/3=10.50

Answer:

New England quarterback Tom Brady has the Patriots rolling again. ... In Week 2, they shut out the hapless Miami Dolphins, 43-0. ... Their start to 2019 has been so strong, even against opponents with a combined record ... and regress their win-loss records to account for the small number of games played.

Step-by-step explanation:

The number of games they won is 12 and the number of games they lost is 4 based on the given ratio.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Suppose the number of games they won is W and the number of games they lost is L.

As per the given

Total games L + W = 16

Ratio W/L = 3/1

W = 3L

L + 3L = 16

4L = 16

L = 4

And, W = 3 x 4 = 12

Hence"The number of games they won is 12 and the number of games they lost is 4 based on the given ratio".

#SPJ2

Given:

Jake bought 3 drawing pens for $8.07.

Each pen costs the same amount.

To find:

How much did he spend for one pen?

Solution:

Let x be the cost of each pen. Then

Cost of three pens = 3x

Jake bought 3 drawing pens for $8.07.

[tex]3x=8.07[/tex]

Divide both sides by 3.

[tex]x=\dfrac{8.07}{3}[/tex]

[tex]x=2.69[/tex]

Therefore, he spend $2.69 for one pen.

Answer:0.75757575757

Answer:

Fraction Form

25/33

Decimal Form

0.75

Step-by-step explanation:

First, convert the mixed fraction into an improper fraction, so it would look like:

-5/3 / (-11/5)

Next, divide. Remember, when multiplying fractions all you do is flip the one in parantheses and make both of them positive, so it would look like:

5/3 x 5/11

Finally, multiply so you do the two top numbers which is 5 x 5= 25 and the two bottom numbers so 11 x 3 is 33. Then your final answer is 25/33

Answer:

x = 40

Step-by-step explanation:

∠D = ∠ADB + ∠BDC

    = 30 + 40

    = 70°

In ΔBDC,

BD = CD

∠DBC = ∠DCB  {angles opposite to equal sides are equal}

∠DBC + ∠DCB + ∠BDC = 180  {Angle sum property}

2∠DCB + 40 = 180

             2∠DCB = 180 -40

             2∠DCB = 140

    ∠DCB= 140/2

∠DCB = 70°

In ΔADC,

x + ∠D + ∠C = 180

x + 70 + 70 = 180

x + 140 = 180

x = 180 - 140

x = 40°

Answer: The family's weekly income is $1500

-------------------------------------------

Work Shown:

x = weekly income (in dollars)

16% of x = amount spent on food per week

16% of x = 240

(16/100)*x = 240

0.16*x = 240

0.16*x/0.16 = 240/0.16

x = 1500

Pls Mark as brainliest

Answer:

1500

Step-by-step explanation:

16% of x = amount spent on food per week

16% of x = 240

(16/100)*x = 240

0.16*x = 240

0.16*x/0.16 = 240/0.16

x = 1500

Answer:

£1560

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year,

then, solving our equation

I = 1200 × 0.06 × 5 = 360

I = £ 360.00

The simple interest accumulated

on a principal of £ 1,200.00

at a rate of 6% per year

for 5 years is £ 360.00.

Answer:

golden corral equation y=1.5x+15

western sizzlin equation y=2.5x+13

yes they are linear because if you were to graph them they would have a straight line and they would go upwards because the slope is positive

For which one you would pick would depend on how much you drink. If you drink a lot you should probably go to golden corral but if you dont drink that much then western sizzlin is probably the best choice.
