Answer:

She baked 640 cookies at first.

Step-by-step explanation:

Let cookies be x and muffins be y,

Let cookies remaining be z and remaining muffins be a

x = 264 + y

now,

x - 3/8 of x = z

x - 3x/8 = z

or, (8x-3x)/8 = z

so, z = 5x/8

Now,

y - y/2 = a

or, (2y-y)/2 = a

so, a = y/2

Now,

z + a = 588

or, 5x/8 + y/2 = 588

as we know x = 264 + y,

or, 5(264 + y)/8 + y/2 = 588

or, (1320 + 5y)/ 8 + y/2 = 588

or, (2640 + 10y + 8y)/16 = 588

or, 2640 + 18y = 9408

or, 18y = 9408 - 2640

or, 18y = 6768

so, y = 6768/18

so, y = 376

now,

x = 264 + y

or, x = 264 + 376

so, x = 640

Answer:

900 batteries

Step-by-step explanation:

First we must find how many batteries does 1 calculator need

we can do this by dividing 160 by 40

which will give us 4 batteries per calculator

then we multiply the amount of calculators we have with 4

225×4 = 900 so we need 900 batteries

Answer:

2.2      Solve  :    3x-20 = 0

Add  20  to both sides of the equation :

                     3x = 20

Divide both sides of the equation by 3:

                    x = 20/3 = 6.667

x = 20/3 = 6.667

Answer:

24/5

Step-by-step explanation:

1 1/5 is equal to 6/5. 4 times 6/5 is first 4 times 6 which is 24 and then /5. So the answer is 24/5

Answer: 240mph

Step-by-step explanation:

[tex]volume \: = \frac{1}{3} \times base \: area \: \times \: height \\ [/tex]

Thus :

[tex]80 = \frac{1}{3} \times 24 \times h \\ [/tex]

[tex]h = \frac{80 \times 3}{24} \\ [/tex]

[tex]h = \frac{240}{24} \\ [/tex]

[tex]h = \frac{24 \times 10}{24} \\ [/tex]

[tex]h = 10 \: cm[/tex]

Thus the last option is the correct answer.

Answer:

the volume should be 2/15

Answer:

yes they are all functions

Step-by-step explanation:

Despite f(x) being the classic way to write a function,

a function has:

A function relates each element of a set with exactly one element of another (possibly the same) set.  

One-to-one and many-to-one are functions, but one-to-many is not a function.

You can also carry out the Vertical Line Test on a graph.  If the vertical line only crosses the curve once, it is a function.  If it crosses more than once it is still a valid curve, but is not a function.

Yes they all are functions

Functions should include

Zarab pay for all candies = 5x

Zarab pay for all cakes = 20 y

Total cost = 5x + 20y

Money spent = 5x + 20y

= 5 × 10 + 20 × 5

= 50 + 100

Answer:

23° and 157°

Step-by-step explanation:

Let n represent the smaller angle then the larger angle would be...

n+134

Supplementary angles add up to 180 degrees. We can use this information to set up an equation...

n+n+134=180

Combine like terms

2n+134=180

Subtract 134 from both sides

2n=46

Divide both sides by 2

n=23

n+134=157

23° and 157°

Answer:

6 grapples

Step-by-step explanation:

x = number of wins

y = number of ties

y = 15 - x

48 = 5x + 2y

48 = 5x + 2(15 - x)

48 = 5x + 30 - 2x

48 = 3x + 30

18 = 3x

x = 6

The number of grapples that Jeremy win will be 6.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

Sensei's Judo Club has a competition for the students.

Let x be the number of wins and y be the number of ties.

If you win a grappling match, you are awarded 5 points.

Then the equation will be

x + y = 15

y = 15 - x

If you tie, you are awarded 2 points.

Jeremy grappled 15 times and his score was 48 points.

Then the equation will be

5x + 2y = 48

Put the value of y in the above equation. Then we have

5x + 2(15 - x) = 48

5x + 30 - 2x = 48

3x = 18

x = 6

The number of grapples that Jeremy win will be 6.

MALPI THE NUBERS

Answer:

11.5 hours

Step-by-step explanation:

It would take Seith x hours to paint the room by himself, then Ted needs x + 1 hour.

During 1 hour, Seith can do 1/x of the work, Ted can do 1/(x+1) of the work, then we have

1/x + 1/(x + 1) = 1/6

(2x + 1)/[x(x+1)] = 1/6

x(x+1)=6(2x+1)

x^2 + x = 12x + 6

x^2 - 11x - 6 = 0

[tex]x=\frac{11+\sqrt{145}}{2}= 11.5 hours[/tex]

Answer:

The simplified version of this equation is -3x - 12.

Step-by-step explanation:

To simplify this equation, distribute -3 to both x and 4.

-3(x+4) = -3x -12

Answer:

-3x-12 as an expression

Step-by-step explanation:

To solve this problem, we need to distribute!

Multiply -3 by both the x and the 4

When we do this, we get:

-3x and -12

Note: when you multiply a positive by a negative, you get a negative so it turns into a negative number

Note 2: When you see an x without a number in front of it, it becomes 1x. In this problem, that is why it is a -3x because -3 x 1 is -3
