Sue ran 7 miles more than Jill last week. Sue ran 11 miles. Which equation will tell you how many miles Jill ran?A) x + 7 = 11B) x − 7 = 11C) x + 7 = −11D) x − 7 = −11

x is the days that the first team finishes the work alone (x>8)

y --------------------------second-----------------------------------------(y>8)

In a day:

⇒          [tex]\frac{1}{x}+ \frac{1}{y} =\frac{1}{8}[/tex]               (1)

If the first team works alone for two days and the second team works alone for 5 days, 5/8 of the total work still remains:

⇒          [tex]\frac{2}{x}+\frac{5}{y}=\frac{3}{8}[/tex]                (2)

(1),(2)   ⇒   [tex]\left \{ {{\frac{1}{x}+ \frac{1}{y} =\frac{1}{8}} \atop {\frac{2}{x}+\frac{5}{y}=\frac{3}{8}}} \right. <=>\left \{ {{x=16} \atop {y=24}} \right.[/tex]

It'll take the first team 16 days and the second team 24 days to finish the work alone

ok done. Thank to me :>

Answer:

21.94

Step-by-step explanation: because i did some basic math

Answer:

ok so i think it is 5/9

Step-by-step explanation:

both equal 0.5 in decimal point

Answer:

The last option is correct

Step-by-step explanation:

Eg: i take  -4/9

If your answer id 4/-9 , the negative sign will always go on the top so answer will be -4/9

Thus its similar

Hope you understood

if not I will explain again !

Your welcome !

Answer:

D

Step-by-step explanation:

gradient is change in y/change in x

gradient of UV = 14-8/12+4=3/4

use equation y=mx+c where y is the y coordinate, m is the gradient, x is the x coordinate and c is the y intercept

use one of the coordinates of U or V, I'll use (4,8)

[tex]y = mx + c[/tex]

[tex]8 = \frac{3}{4} (4) + c[/tex]

[tex] 8 = 3 + c[/tex]

c is 5

the equation for UV is

[tex]y = \frac{3}{4} x + 5[/tex]

insert each X coordinate given in the question to see if it gives the same y coordinate

when x is 20, y is also 20 so the answer is D

Answer:

it's D for sure.........

Answer:

46 units

Step-by-step explanation:

So first of all you do 8 × 2 which equals 16 units, then you do 15 × 2 which equals 30 units, then you 30 + 16 which equals 46 units. Hope this helps.

Answer:

Hello There!

According to the question,

It is said that we have to find calories in 4 cups.

First we have to find in each cup.

So

[tex] \frac{3}{4} \times x = 99 \\ \\ so \: x = 99 \times \frac{4}{3} \\ \\ [/tex]

simplify 99 and 3 then it will look like

[tex]33 \times \frac{4}{1} [/tex]

1 has no value so 33×4=132 calories

Now it is in each cup or 1 cup.

To find in 4 cups, multiply 132×4

[tex]132 \times 4 = 528[/tex]

So 528 calories is the answer.

Answer:

[tex]\huge\boxed{\sf v = 80\ mph}[/tex]

Step-by-step explanation:

Given Data:

Distance = S = 100 miles

Time = t = 1 1/4 hours = 1.25 hours

Required:

Speed = v = ? mph

Formula:

v = S/t

Solution:

v = 100 / 1.25

v = 80 mph

Answer:

72 sq in.

Step-by-step explanation:

I'm not sure what you mean, but it sounds like the base is 9 in, the side is 10 in, and the height is 8 in. If so, the area is 9 * 8 = 72 sq in.

Answer:

210 Were First Graders

Step-by-step explanation:

35 percent of 600 is the same as 35 per hundred of 600. We can therefore make the following equation:

35/100 = X/600

To solve the equation above for X, you first switch the sides to get the X on the left side, then you multiply each side by 600, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:

35/100 = X/600

X/600 = 35/100

X*600/600 = 35*600/100

X = 21000/100

X = 210

The work above shows the long way to explain how to calculate 35 percent of 600 in order to give you a foundation and better understanding of how to calculate percentage. In the future, you could use this simplified formula:

(Y * P)/100

In our problem "What is 35 percent of 600?", Y is 600 and P is 35:

(600 * 35)/100 = 210

And once again you see that the answer is 210.

Answer:

210 kids

Step-by-step explanation:

So the formula is basically part over whole is equal to x/100%

So for here it would be x/600 = 35/100

Solve that and you will get 210

Answer:

48

Step-by-step explanation:

20 scrunchies=3 dollars

7.25 dollars = ?

1 dollar=6.66666666

0.25 dollar=1.666666666666

7*6.66666666=46.666666

:)

Answer:

Kenzie can buy 48 Scrunchies

Step-by-step explanation:

You have to divide 3 by 20. (3/20) Which is also 1.5/10 and as a decimal, that is 15 cents. So one scrunchie is equivalent to 15 cents, which means how many times can you take .15 from 7.25 is how many scrunchies she can buy. So how many times does .15 go into 7.25? The answer is 48.3(repeating). So you have to round it down because if you round it up she needs more money.

I hope that helped :)

Answer:

3 for the price of 2

Step-by-step explanation:

I had this question

Okay, they all equal 30 bucks. The first one would change into 20 bucks and the other would be Take off 10 by 30, 20,   20 with 25% off is 15. Then 15 + 10 is 25.

First one = 20.

Second one = 25.

Three for the price of two is cheaper.

32 x 28

you just have to flip them, and it'll be commutative! :D
