Answer:
22
Step-by-step explanation:
We can use the order of operations (PEMDAS), to solve this equation.
We must first multiply and divide, and order. This means we divide 12 by 3 and get 4, then multiply that by 2 and get 8. (30-12÷3×2,30-4×2,30-8). Now we just subtract 8 from 30 and get 22 as our answer.

A fish was swimming 2 ½ feet below the water's surface at 1:00 pm. Three hours later, the fish was at a depth that is 3 ¼ feet below where it was at 1:00 pm. What rational number represents the position of the fist with respect to the water's surface at 4:00 pm?
Answer:
The fish will be at a distance of 5 3/4 ft from the water surface at 4:00 pm
Step-by-step explanation:
Here, we want to find a rational number that represents the position of the Fish at 4pm
Initially it was at a depth of 2 1/2 ft below the water surface
At 4pm, it went 3 1/4 ft further
Thus, its position with respect to the water surface at 4 pm will be;
2 1/2 + 3 1/4
= 5/2 + 13/4 = (10 + 13)/4 = 23/4 = 5 3/4 ft

The relationship between x and y is proportional. When x is 3, y is 51. The value of x will be 3468 when y is 204.
What is a proportional relationship?
It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
It is given that, the relationship between x and y is proportional. When x is 3, y is 51.
Since the relationship between x and y is proportional. The constant ratio of the two proportional values y/x is represented by the symbol k, which may be a positive rational number. The x value and the y value are directly proportional, as in the equation y = kx.
x ∝ y
x=ky
k=y/x
k=51/3
k=17
We have to find the value of x when y is 204.
x=ky
x=17×204
x=3468
Thus, the relationship between x and y is proportional. When x is 3, y is 51. The value of x will be 3468 when y is 204.

4(x-7)=2x-6 (show work)
Answer:
x = 11
Step-by-step explanation:
Given
4(x - 7) = 2x - 6 ← distribute parenthesis on left side
4x - 28 = 2x - 6 ( subtract 2x from both sides )
2x - 28 = - 6 ( add 28 to both sides )
2x = 22 ( divide both sides by 2 )
x = 11

Operations with fractions
Fractions can be defined as the quotient of two integer numbers. There are three types of fractions:
* Proper fractions: When the numerator is less than the denominator. Example: 2/5
* Improper fractions: When the numerator is greater than or equal to the denominator. Examples: 7/5, 13/13
* Mixed fractions: They are given as an integer followed by a proper fraction. Example: [tex]\displaystyle 4\frac{1}{3}[/tex]
Leah has a 15-meter long ribbon and is creating satin bows for weddings. She takes two pieces out of it. The total length of ribbon taken is the sum of both fractions:
Total cut:
[tex]\displaystyle 3\frac{4}{9}+6\frac{5}{9}[/tex]
To add these fractions, we add the integer parts and apart from the proper fractions:
[tex]\displaystyle 3\frac{4}{9}+6\frac{5}{9}=3+6+\frac{4}{9}+\frac{5}{9}=9+\frac{9}{9}=9+1=10[/tex]
Now we can calculate the remaining length of ribbon:
Remaining riboon= 15 m - 10 m = 5 m
Leah has 5 meters of ribbon left.

Find the slope of the line passing through each of the following pairs of points and draw the graph of the line. (5, 2), (3, 3)
Answer:
-0.5
Step-by-step explanation:
slope=rise/run or y/x in other words(y2-y1/x2-x1)(y2-y1) is 3-2 so y2-y1=1(x2-x1) is 3-5 so x2-x1= -2-1/2 or -0.5 would be the slope.Answer:
1/-2
Step-by-step explanation:
5 = x1, 2 = y1
3 = x2, 3 = y2
y is always before x
y2 - y1 = 3 - 2
3 - 2 = 1
You can always subtract y1 by y2, but I am just doing it the other way. But if you choose to subtract 2 by 1, you have t do that for x also.
x2 - x1 = 3 - 5
3 - 5 = -2
After this step, you put y on top, and x on the bottom, making:
1/-2
