Answer:
y : x: = 5 : 4
Step-by-step explanation:
x to y = 4 to 5
Rewrite;
x:y = 4:5
Remember, a ratio is another way of representing a fraction, hence one can do the same operations that one could do with a fraction. Therefore, one can take the cross products of a ratio;
x : y= 4 : 5
5x = 4y
Inverse operations;
5x = 4y
x = [tex]\frac{4}{5}[/tex]y
Now substitute this into the equation y:x
y : [tex]\frac{4}{5}[/tex]y
Rewrite as a fraction;
[tex]\frac{y}{\frac{5}{4}y}[/tex]
Simplify;
[tex]\frac{1}{\frac{4}{5}}\\\\\frac{5}{4}[/tex]
Rewrite as a ratio;
y : x = 5 : 4

Answer:

Step-by-step explanation:
The area (A) of the rectangle = length × breadth, that is
A = BC × CA
= (x + 3)(x + 2) ← expand using FOIL
= x² + 5x + 6
Given that A = 9 , then
x² + 5x + 6 = 9 ( subtract 6 from both sides )
x² + 5x = 3 ← as required

- The length of Christina's table is the product of 4 and X. The width of her table is 2 less
than twice the length. What is the perimeter of her table?
Answer:
24x - 4
Step-by-step explanation:
Perimeter of a table = 2(length + width)
length of Christina's table is the product of 4 and X
Length = 4x
The width of her table is 2 less
than twice the length.
Width = 2(4x) - 2
= 8x - 2
Perimeter of a table = 2(length + width)
= 2{4x + (8x - 2)}
= 2(4x + 8x - 2)
= 2(12x - 2)
= 24x - 4
Perimeter of a table = 24x - 4

An amusement park sold 810 discount tickets and 90 full-price tickets. What percentage of the tickets sold were discount tickets? HELP ME ASAP PLEASEEEEE
Answer:
90%
Step-by-step explanation:
First, find the total number of tickets sold.
810 discount + 90 full-price = 900 tickets
Now you need to find what percent 810 is of 900.
% of 900 = 810
810/900 = 0.9
Convert this to a percentage.
0.9 × 100% = 90%
90% of tickets were sold at a discount.

what's the domain and range of y=-2x^2+5x-7
Answer:
Domain: All real numbers Range: (-∞, -31/8]
Step-by-step explanation:
Since the parent function for this equasion is y=x^2, you know that the graph wil be parabolic in shape. All parabolic functions have a domain of all real numbers. Now when you rewrite the graph in vertex form, you will see that the top vertex is at y=-31/8, this is going to restrict the range to be (-∞, -31/8]. I have provided a graph using the app PhotoMath.
11x + x = 60
full answer pls
Answer:
x=5
Step-by-step explanation:
First combine the like terms:
11x+x = 12x
then you'll get 12x=60
divide by 12 to get x by itself
whatever you do on one side you have to do on the other so :
12x/12=60/12
x=5
your answer is 5
Answer:
11x + x =12x thus
12x/12 =60/12
x=5
value of x is 5

3(x + 4) = 36.
Answer:
x = 8
Step-by-step explanation:
3 ( x + 4 ) = 36
divide both sides by 3
x + 4 = [tex]\frac{36}{3} }[/tex]
divide 36 by 3 to get 12
x + 4 =12
subtract 4 from both sides
x = 12 - 4
subtract 4 from 12 to get 8
x = 8

9514 1404 393
Answer:

consider the value of a group of coins
Step-by-step explanation:
The coins are in equal numbers, so they can be considered as a group. The value of one group of 4 coins is ...
1¢ + 5¢ + 10¢ + 25¢ = 41¢ = $0.41
Then the number of groups (g) of coins is ...
$3.28 = $0.41×g
g = $3.28/$0.41 = 8
There are 8 groups of coins. Each group has 4 coins, so there are ...
(8 groups)×(4 coins/group) = 32 coins
