tonight's attendance was 100 more than double the attendance last night. If 500 attended tonight, how many attended last night?

Answer:

100:2  =200:x

200*2/100=4

Step-by-step explanation:

Answer:

x = 5

Step-by-step explanation:

Step 1: Distributive property

Using this property means when you have something like the equation on the right side ( 4 ( x + 3 ) ) you multiply both the values in the parentheses by the number outside:

4 ( x + 3 )

( 4 x X ) + ( 4 x 3 )

4x + 12

8x + 2 = 2x + 4x + 12

Step 2: combine like terms

Combining like terms is when you find like terms with the same variables and such and add them together:

8x + 2 = 12 + ( 2x + 4x )

8x + 2 = 12 + 6x

Step 3:Using inverse operations

This means that you need to get a variable one one side and a constant on the other:

8x + 2 ( -2 ) = 12 ( -2 ) + 6x

8x = 10 + 6x

8x ( -6x ) = 10 + 6x ( -6x )

2x = 10

Step 4: solve for the variable

The last thing you need to do is divide both sides by the constant with the variable ( 2x ) to get x by itself:

2x ( /2 ) = 10 ( /2 )

x = 5

Answer:

x=5

Step-by-step explanation:

Step 1:Using the distributive property on the right side of the equation

8x+2=2x+4(x+3)

8x+2=2x+4x+12

Step2:Combining the like terms on the right side if the equation (Since there are no like terms on the left side) :

8x+2=6x+12

Step 3: Using the inverse operations to get the variables on the left side and the constants on the right side of the equation :

8x-6x=12-2

Step4: Using inverse operation to solve for the variable of interest which is 'x':

2x=10 (Dividing both sides by two sides by 2)

x=5

The equation is y = 0.60x. Then the total cost of 9 lbs of bananas will be 5.4 lbs.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

The cost of bananas, y, is directly proportional to x, the pounds of bananas purchased. Then the relationship is given as,

y ∝ x

y = kx

Then the relationship between 'x' and 'y' will be linear.  If 2.5 lbs of bananas cost $1.50. Then we have

1.50 = k (2.5)

k = 0.60  

Then the equation is given as,

y = 0.60 x

Then the total cost of 9 lbs of bananas will be given as,

y = 0.60 (9)

y = 5.4 lbs

The equation is y = 0.60x. Then the total cost of 9 lbs of bananas will be 5.4 lbs.

Answer:

n = (15)(3) = 45

Step-by-step explanation:

This problem is very simple, all we need to do is take the information we get and put it in equation form.

Jessie made 15 calls, Clay made 3 times as many as her. 15 times 3 is 45. Put in equation format it will look like:

n = (J) * (3)

n is how many calls Clay made, and J is how many calls Jessie made.

Answer:

[tex]x = \frac{41}{2} [/tex]

Step-by-step explanation:

x - 5 - 3x + 1 = -45

-2x - 4 = -45

-2x = -45 + 4

-2x = -41

x = 41 ÷ 2

x = 41/2

Step-by-step explanation:

[tex]\tt{}x - 5 - 3x + 1 = - 45[/tex]

[tex]\tt{} - 2x - 4 = - 45[/tex]

[tex]\tt{}- 2x= - 45 + 4[/tex]

[tex]\tt{} - 2x = - 41[/tex]

[tex]\tt{} x = \frac{41}{2} [/tex]

Answer:

Yes. f(x) and g(x) are inverses of one another

Step-by-step explanation:

[tex]f(x) = - \frac{1}{2} x - 2 \\ y = - \frac{1}{2} x - 2 \\ x = - \frac{1}{2} y - 2 \\ x + 2 = - \frac{1}{2} y \\ - 2(x + 2) = - \frac{1}{2} y \times - 2 \\ - 2x - 4 = y \\ {f }^{ - 1} (x) = - 2x - 4[/tex]

In step 1 we just copied the original function.

In step 2 we substituted y for f(x).

in step 3 we switched the variables.

in step 4 we added 2 to both sides.

in step 5 we multiply both sides by -2

In step 6 we solved for y.

In step 7 is just a fancy way of saying the inverse function f(x) = -2x - 4

Answer:

Step-by-step explanation:

Answer:

Marta can arrange a maximum of 3 plates.

Solution:

Given, Marta has just moved to a new town and wants to share plates of baked goods with her neighbors.

She has 18 cookies and 15 brownies to share, and wants to split them equally among the plates with no food left over.  

We have to find what is the greatest number of plates she can make to share?

Now, let the number of brownies per each plate be n.

Then, number of plates used =  

Here, n is number of brownies per plate and  is number of cookies per plate.

So, both n and  should be whole numbers. Then, for  to be whole number 6n must be an multiple of 5.

And to be particular, n should be a multiple of 5 as 6 is not multiple of 5.

So, possible n values are, 5, 10, 15. We need not take above 15 as number of brownies available are 15

In order to arrange in more plates we have to take less count in single plate. Then, n = 5.

Now, number of plates  

Hence, Marta can arrange a maximum of 3 plates.

then

    (9x + 18) = (2x + 19)

9x + 18 - 18 = 2x + 19 - 18
