Answer: No
Explanation:
Replace p with 2 and simplify
8 ≠ 3p + 2
8 ≠ 3(2) + 2
8 ≠ 6 + 2
8 ≠ 8
We get a false claim, so the original inequality 8 ≠ 3p + 2 is false when p = 2. Meaning that p = 2 is not a solution.
If the "not equal" sign was changed to an equal sign, then we would have a solution.
Answer:
no / false
Step-by-step explanation:
If we set the "p" in this equation to be equal to 2 (p = 2), we can test this inequality:
8 ≠ 3p + 2
8 ≠ 3(2) + 2
8 ≠ 6 + 2
8 ≠ 8
FALSE STATEMENT
so, p = 2 is not a solution to this inequality
(no)
hope this helps!!
{"≠" means the opposite of = [the two sides of the equation are not equal, which is not true for this situation] }

If a certain measurement of a polygon is 283 in2, it means:
A. the polygon's measurements are 283 inches by 283 inches.
B. the polygon's volume is 283 in?
C. 283 one-inch by one-inch squares will fit over its surface.
D. none of the above.
Answer: C
Step-by-step explanation:
A says the polygon's measurements are 283 inches by 283 inches. Is it Correct? No. If we multiply these numbers we get 80,089 inches squared, which is not equal to our actual surface of 283 inches squared.
B says the polygon's volume is 283 inches cubed, which is not correct because it says that a certain measurement of a polygon is 283 inches squared, not cubed, which means we got a surface/area, not a volume.
C says that our 283 inches squared area could fit 283 one-inch by one-inch squares, which is correct because one-inch by one-inch is an one inch squared area, if we multiply this one-inch squared by the number 283, we get 283 inch squared area.
And D couldn't be because the answer is C.

Yes, because the quotient of Fraction 1 and 3 over 4 ÷ fraction 2 over 3 is 2 and 5 over 8
No, because the quotient of Fraction 2 over 3 ÷ Fraction 1 and 3 over 4 is 1 and 2 over 12

Mary's desk was 67.94 inches long, Joe's desk was 78.26 inches long and Troy's desk was x inches long. If the length of all the desks combined was 214.62 inches, how long was Troy's desk?
Answer:
68.42
Step-by-step explanation:
We know that when we add the lengths of all of the desks together, the total is 214.62. Based on that information, we can set up the following equation: 67.94 + 78.26 + x = 214.62. From there, all you have to do is add 67.94 + 78.26 to get 146.2. Lastly, you simply do 214.62 - 146.2 to get 68.42. Hope this helps!

Answer:
If it is a perfect square, k=0 in the form y=a(x-h)^2+k.

Daniel is a piano instructor who gives lessons on weekends. The cost of one lesson is $30. Daniel is offering a 5-lesson package with a 25% discount off the total price.
How much would a student save by buying a multi-pack compared to 5 separate lessons?
Why would Daniel offer a discount when he knows he could earn more money selling the lessons separately?
Answer:
150 is if you buy them separately but 150-25%=112 so 150-112=38 so students would save $38
Step-by-step explanation:
he made that package so that more people would go to his lessons know that there was a discount going on and more people would choose his lessons over people who don't have discounts.

Answer: C
Step-by-step explanation:
Step 1: Find the unit rate (tomatoes per bowl)
Last time, the ratio was 9:12, or 9 tomatoes for 12 bowls of soup. To finndd the unit ratet, dividde the ffirst given unnit by the 2nd. In this case, tomatoes is the first unit, and bowls is the second. So the unit rate is:
9÷12= 0.75, or 3/4 of a tomato per bowl of soup.
Now, the ratio is 6:8, or 6 tomatoes for 8 bowls of soup. The unit rate is
6÷8= 0.75, or 3/4of a tomato per bowl of soup.
Step 2: Compare
As you can see, the number of tomatoes per bowl of soup hasn't changed at all. So the answer is C.
Hope this helps :)
Answer:
Todays’s soup will taste the same.
Step-by-step explanation:
9 tomatoes for every 12 cups of soup- ratio= 9/12=3/4
6 tomatoes for every 8 cups of soup- ratio=6/8=3/4
They both end in the same ratio, which is 3/4.
A rectangular-shaped dining room table is modeled by the figure given below. A) Write an equation to represent the area of the dining room table. B) If the the area of the table is 112 ft2, what are the dimensions of the dining room table?
Answer:
A) (x+10)(x+4) = ?
B) (x+10)(x+4) = 112, solve for x
Step-by-step explanation: you multiply the two equations to get the area.
Answer:
a)[tex](x^{2} +14x+40)ft^{2}[/tex]
b)14ft, 8ft
Step-by-step explanation:
a) Area of Rectangle = Length x Breadth
= [tex](x+10)(x+4)\\=x^{2} +4x+10x+40\\=(x^{2} +14x+40) ft^{2}[/tex]
b) Given Area of rectangle = [tex]112ft^{2}[/tex]
[tex]x^{2} +14x+40=112\\x^{2} +14x-72=0 (Quadratic Equation)\\\\[/tex]
Quadratic Equations: [tex]ax^{2} +bx+c = 0\\[/tex]
In this case, a = 1, b = 14, c = -72
[tex]\frac{-b+/-\sqrt{b^{2}-4ac } }{2a} \\= \frac{-14+/-\sqrt{14^{2} 4(1)(-72)} }{2(1)} \\= 4 or - 18 (reject)[/tex]
We reject negative values.
so x = 4,
The length of table = (x+10) ft = 4+10 = 14ft
The breadth of the table = (x+4) ft = 4 + 4 = 8ft

Translate the following phrase to a mathematical expression.
a number times fifteen
(A) 15 n
(B) 15 + n
(D) 15 ÷ n
(C) n15
Answer:
I think C
Step-by-step explanation:
A number times fifteen would be n • 15 or just n15.
The reason it is not 15n is because it asks a "number" which in this case is represented by the letter n. That letter is now multiplied (times) by 15. So therefore the number "n" times 15 is n15.
