You are planning a skating party at a rink that charges a basic fee of
$10.00 and $6.00 per person for catered parties. You don't want to spend
more than $52.00. Write and solve an inequality to find the number of
friends you can invite.
a. 6x + 10 < 52; x< 7
6. 6x + 10 > 52; <> 7
C. 6% + 10 > 52; 2 >7
d. 6x + 10 < 52; x < 7

Answers

Answer 1

Answer:

y = 6.50x + 6 or 71 = 6.50x + 6

10 people are the max you can invite

Step-by-step explanation:

We have the simple equation

y = 6.50x + 6

6.50x because it it per person

6 because it is a flat one time charge

We want the max to be 71 so that will be our y

71 = 6.50x + 6

We are now going to solve for x

65 = 6.5x

x = 10

Hope it helps! (:

a rectangle is 6 times as long as it is wide. the perimeter is 140 cm. find the area of the rectangle. round to the nearest tenth if necessary.

Answers

Answer: [tex]w = 10[/tex]

Step-by-step explanation:

Our perimeter will be 140 cm and our width of the rectangle will be 6w. We will then divide 14w and 140 by 14 so we can get w by itself. Then, we will divide the perimeter by the width.

Step 1: Let 6w will be our length and let the perimeter be 140 cm.

[tex]6w, P = 140 cm[/tex]

Step 2: Perimeter means that you add up all the 4 sides of the rectangle.

[tex]P = 140 = w + w + 6w + 6w = 14w[/tex]

[tex]P = 140, 14w[/tex]

Step 3: Divide both sides 14 to get the single w variable.

[tex]\frac{140}{14} = \frac{14w}{14}[/tex]

Step 4: Simplify.

[tex]10 = w[/tex]

Step 5: Flip sides.

[tex]w = 10[/tex]

Grandma's age is 6 years less than 5 times Junior's age, j. If Grandma is 64 years old, which equation
can be used to find Junior's age?

Helppp

Answers

Answer:

junior is 6

Step-by-step explanation:

take 64 and divide by 5 you get 12 then take away the 6 years and you get juniors age which is 6

The equation used to find the age of Junior's age is 64 = 5J - 6 and the age of Junior will be 14 years old.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say Grandma's age is G while junior is J.

As per the given,

Grandma's age is 6 years less than 5 times Junior's age,

G = 5J - 6

64 = 5J - 6

J = 14

Hence "The equation used to find the age of Junior's age is 64 = 5J - 6 and the age of Junior will be 14 years old".

Answers

Answer:

Not exactly

Step-by-step explanation:

Cost lamp = $89.95Cost of comforter set = $239.99Sales tax = 6.5%

Total payment:

($89.95 + $239.99)*1.065 = $351.39

Total amount is a little different:

$351.72 vs $351.39

Write an equation in Slope intercept form of the line that passes through the given points (-3,4) (1,4)

Answers

answer would be “y=4”

to find the answer: first you have to find the slope with the given points. (y2 - y1 / x2 - x1)

plug it in to get: (4-4 / 1- -3) = 0/4 = 0

this means the slope would be 0

if the y intercepts are the same then it usually indicates that the slope would be 0 and that the answer is the y intercept.. but if you don’t understand how to get slope-intercept using other coordinates then here’s how:

you can use point-slope formula (y-y1 = m (x-x1) in order to do this just plug in one of the coordinates. in this case an example of point-slope form would be:
y-4 = 0 (x - -3) or y-4 = 0(x-1)

it doesn’t matter which coordinates you use..

then solve the point slope for slope-intercept.

y-4 = 0(x-3) multiply 0 with x and -3
y-4 = 0x move -4 to the right by adding 4

y = 0x + 4 or y = 4 would be your answer!

The equation for the line that passes through the point A ( -3 , 4 ) and

B ( 1 , 4 ) is y = 4

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the first point be A ( x₁ , y₁ ) = A ( -3 , 4 )

Let the second point be B ( x₂ , y₂ ) = B ( 1 , 4 )

Now ,

The equation for the line is given by

y - y₁ = m ( x - x₁ )

To find the slope of the line ,

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values , we get

m = ( 4 - 4 ) / 1 - ( - 3 )

m = 0

So , the slope of the line is 0

Now ,

The equation of line will be

y - 4 = 0 ( x - ( -3 ) )

y - 4 = 0

Adding 4 on both sides , we get

y = 4

So , the equation of the line is y = 4

The bike store marks up the wholesale cost of all of the bikes they sell by 30%. Andre wants to buy a bike that has a retail price of $125. We need to find the wholesale (original) price of this bike. What percent of the wholesale (original) price is the retail price?

Answers

Answer:

Wholesale Price = $96.15Retail price percentage = 130%

Step-by-step explanation:

Wholesale price was marked up by 30% and became $125.

Assume wholesale price is x. Expression will be;

125 = x + (30% * x)

125 = 1.3x

x = 125/1.3

x = $96.15

Retail price percentage = 125/96.15

= 1.30

= 130%
