Answer:
3. b= 5
4. d= -5
5. z= 2/3
Step-by-step explanation:
3) 5b-3=22
5b=25 add 3 to both sides
b= 5 divide 5 from both sides
4) 1.5d+3=-4.5
1.5d=-7.5 subtract 3 from both sides
d=-5 divide 1.5 from both sides
5) 4=9z-2
6=9z add 2 to both sides
6/9=z divide 9 from both sides
2/3=z simplify

Frank drives 60 miles per hour, and this relationship is graphed, which ordered pair would not be on the graph?
(4, 280)
(0, 0)
(2, 120)
(6, 360)
Answers
Answer:
4 and 280
Step-by-step explanation:
Reason:
Frank drives 60miles per 1 hour ( 1:60)
If he drives 120miles, its per 2hours because you multiply by 2.
If he drives 360miles, its per 6 hours
Because 60x6=360 and 1x6=6 (6:360)
4,280 is odd one out because if he drives 4hours, you multiply 60 by 4 to get 240, 280 is incorrect

Kyle says that you can only find the volume of a rectangular prism if you have the measurements of the length, width, and height of the rectangular prism. Millie tells him that he is incorrect. She says that you can find the volume of a rectangular prism if you know the area of the base and the height. Why is Millie correct? Justify your answer.

but the two angles on the bottom are equal and all three angles in the triangle add up to 180 so if you subtract 40+40 because of the x and 40 then you will have y being 80
Brett create a function of X with seven points each in a different location on the grid he graph sixth of the points as shown use the add point tool to show the location of a point that could be the seventh point of Brett function
Answers
Answer:
any point where x=3, 4, or 6.
Step-by-step explanation:
The thing that makes a function a function and not a relation is having only 1 y value per x value, which means if you draw a vertical line through a point, it should not intercept any other points. Basically, the main difference between a function and a relation is that a function can't have 2 points on top of each other.
Pick a point where x=3, 4, or 6. Those are the open spots on the grid with nothing above or below them. It doesn't matter which point you pick, as long as there is NOTHING directly above or below that point.

Answer:
[tex]n = 32[/tex]
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and equals:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction.
~
First, add 10 to both sides of the equation:
[tex]\frac{n}{2} - 10 = 6\\\ \\\frac{n}{2}- 10 (+10) = 6 (+10)\\ \\\frac{n}{2} = 6 + 10\\\\\frac{n}{2} = 16[/tex]
Next, isolate the variable n by multiply 2 to both sides of the equation:
[tex]\frac{n}{2} = 16[/tex]
[tex]\frac{n}{2} *2 = 16 * 2[/tex]
[tex]n = 16 * 2\\n = 32[/tex]
[tex]n = 32[/tex] is your answer.

A division equation can be rephrased (i guess thats what you call it) into fraction form. The equation for C is 3 divided by 8, which can be put into fraction form as 3/8. Hope this helps!
Answer:
The answer is C
Step-by-step explanation: When your doing something like this, it's best to be practical and pay attention to the wording
A says 16 pieces of candy shared with 6 friends which is 16/6 which can't be represented by 3/8
B would be represented by 8/3 due to it's wording and the order of which the words are
However C would be 3/8 since the words say, a 3 day trips divided into 8 segments which is 3/8 unlike B which said an 8-foot piece of wood cut into 3 pieces which would be 8/3
D is just 3x8 since he consistanly saves 3 dollars for 8 weeks

Given:

Solution:
Given:
Radius of cylinder: 2.5 inHeight of cylinder: 10 inSurface area of cylinder: 2πrh + 2πr²
Using the formula:
[tex]2\pi rh + 2\pi r^{2} = \text{Surface area of cylinder}[/tex]
