Answer:

White Marbles: 56

Step-by-step explanation:

Let number of white marbles be x

7/10=x/136-x

10x=7(136-x)

10x=952-7x

17x=952

x=56

Answer:

56

Step-by-step explanation:

7/17 * 136 = 56.

Answer:

x = -40

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.

Multiply 5 to both sides of the equation:

(x/5) * 5 = (-8) * 5

x = -8 * 5

x = -40

x = -40 is your answer.

~

Answer:

[tex] \mathbb= > \frac{x}{5} = - 8[/tex]

[tex]\mathbb = > x = - 8 \times 5[/tex]

[tex]\mathbb = > x = - 40[/tex]

Answer: 50 * 100 = 5000

Step-by-step explanation:

a simple way of multiplying numbers that are a 1 with zeros is by simply moving the zeros from that number to the other number

100 has 2 zeros, so you ad them to the 50. 50 with 00 is 5000

Answer: 5O x IOO = 5OOO

Step-by-step explanation:

5OOO, think of it like 5 x 1, 5 x 1 = 5, now add 3 zero’s since there are 3 zeros.

Answer:

B:8x-9y=23

Step-by-step explanation:

First find the slope:

m= y2-y1/x2-x1

y2 is 3

y1 is -1

x2 is 1/2

x1 is -4

3-(-1) is 4

1/2-(-4) is 9/2

Now the equation looks likes this:

4 / 9/2

Which can be rewritten as

4*2/9

Thus the slope is 8/9

So the equation is

y=8/9x+b

Now you can substitute to find the y-intercept:

(you can do either (-4,1) or (1/2,3)

I am going to do (1/2,3) since it is easier

3=8/9(1/2)+b

Simplify:

3=4/9+b

Subtract 4/9 on both sides:

b=23/9

Thus the equation is

y=8/9x+23/9

Multiply 9 on both sides:

9y=8x+23

Subtract 8x on both sides:

8x-9y=23

Answer:

a = 57.5

b = 57.5

Step-by-step explanation:

XY=XZ so c=d

[tex]c = d = \frac{180 - 65}{2} = 57.5[/tex]

Now draw the XH

So angle YXH = 180 — 90 — 57.5 = 32.5

a+YXH=90

a+32.5=90

so a = 57.5

We know that a + 65 + b = 180

So 57.5 + 65 + b = 180

b = 180 — 122.5

b = 57.5

From the above diagram we can conclude that ~

Angle c = Angle a (Alternate interior Angle pair)

Angle d = Angle b (Alternate interior Angle pair)

and,

because their opposite sides are equal.

now, according to linear pair property ~

replacing Angle a with Angle c and Angle d with Angle b, because they are equal to one another ~

(because Angle c = Angle d)

Answer:

x = - 14

Step-by-step explanation:

Given equation

Putting the value of y

Hope it's helpful!

ᔕEᒪEᑎᗩ328

The value of x for the given equation -3x = y + 51 such that the value of y is -9 will be -14.

An equation is said to be linear if the maximum power of the variable is consistently unity.

More than one variable may be present inside a linear equation.

A formula known as an equation uses the same sign to denote the equality of two expressions.

As per the given equation,

-3x = y + 51

At y = -9

-3x = -9 + 51

-3x = 42

x = -14

Hence "The value of x for the given equation -3x = y + 51 such that the value of y is -9 will be -14".

Answer:

1st number is 64

Step-by-step explanation:

Lets start by making the words into equations.

So the 1st plus the 2nd is 75:

1st+ 2nd= 75

Now the tricky part. The 1st is 9 more than 5 times the 2nd. The key word 'times' means multiplication, we we will have 5 x 2nd somewhere in our equation. The '1st is 9 more than' part tricks us into thinking we will have 1st plus 9, BUT WE WON'T because it isn't 9 more, its 9 more THAN. This means we will get.

1st= 5 x 2nd +9

To make this a little cleaner, I will have the 1st = X and the 2nd= y.

x+y=75

x=5y+9

We can substitute the bottom equation into the top equation.

5y+9+y=75

Combine like terms

6y+9=75

Solve for Y by getting y alone.

6y+9=75

6y=66

y=11

Then we can take our value of y and plug it back into either equation to solve for X. The top equation is the easiest.

x+11=75

Isolate x to solve for x

x=64

And we established that x= the 1st number, so the 1st number is 64

Answer:

Taxi Cost = $47.78

Step-by-step explanation:

Taxi Cost = Cost of the ride + (Cost of the ride × sale tax %)        5% = .05 as a

                                                                                                          decimal

Taxi Cost = $45.50 + (45.50 × .05)

 Taxi Cost = $45.50 + $2.275)

  Taxi Cost = $47.775

   Taxi Cost = $47.78

Answer: The answer is 40.

Step-by-step explanation: 7(7-9) when you use distributive property you will use the 7 outside the parenthesis. Multiply the property inside. then you will get 49-9. Then you will solve it and get the answer 40.

Answer:

A. C = (d-ab)/a

Step-by-step explanation:

a(c + b) = d

a(c + b)/a = d/a

c + b = (d/a)

c = (d/a) - b

a(c + b) = d

ac + ab = d

ac = d - ab

ac/a = d/a - ab/a

c = (d/a) - b

Answer:

1/12

Step-by-step explanation:

find the least common multiple of the denominators.

which is 12

so 1/4=3/12

2/3=8/12

1/2=6/12

so 3/12- 8/12 - 6/12 = -11/12

so there is 1/12th pieces left after they all ate their portions of the pie

equal

is

y = 17x

Step-by-step explanation:

After 1 hour , 17   bicycles are produced

After 2 hours, 34 bicycles are produced

Ratio of bikes produced per hour after one hour is

= no. of bikes produced after 1 hr / no of hours

= 17 / 1 = 17

Ratio of bikes produced per hour after two hours is

= no. of bikes produced after 2 hrs / no of hours

= 34 / 2 = 17

a. equal

b. is

equation of y is

no of bikes produced = (rate/ hour) * no of hours

y = 17 * x
