Answer:
1) The equation 1/8(x+16)=76/8 represents the situation, where x is the food bill.
2) The solution x=60 represents the total food bill.
These both answers are correct.
Step-by-step explanation:
Since there are 8 group of friends, and the total amount spent by them is $76 including the tip i.e $16.
If x is the food bill our equation can be:
(x+16)/8 = 76/8
(x+16)/8 = 9.5
x+16= 9.5*8
x= 76 -16
x= 60
The food bill is x=60.

Classify the number 1/2 into as many categories as it belongs: Natural number, whole number, integer, or rational number.
Answer:
1/2 is a rational number.
Step-by-step explanation:
A rational number can be expressed as a ratio of two numbers. 1/2 is a ratio.
It is also a real number, however you do not list that as a category, so from what you listed, it is only a rational number.

Louise completed the work shown below.
(5x3 + 3)2 = (5x3)2 + (3)2 = 25x6 + 9
Determine if Louise’s answer is correct. Explain.
Answer:
SAMPLE RESPONSE
Step-by-step explanation:
Louise’s answer is not correct. She is missing the term 30x3. When squaring a binomial, it is best to write the product of the binomial times itself. Then you can use the distributive property to multiply each term in the first binomial by each term in the second binomial. Louise also could have used the formula for a perfect square trinomial, which is found by squaring a binomial.

Formula: a^2 + b^2 = c^2
so substitute the numbers like this:
10^2 + 6^2 = c^2
both 10^2 and 6^2 are perfect squares:
10 × 10= 100 and 6 × 6= 36
100 + 36= c^2
add:
100 + 36 =
136 = c^2
now in order to get rid of the squared, you put it into a radical:
√136 = √c^2
note: whatever you do on one side, you do to the other
it's easier to use the calculator for this so put √136 and you're gonna get 11.66
since it's asking you to round it to the nearest tenth:
11.66 = 11.7

What’s the answer to this ???
Answer:
-5, 3
Step-by-step explanation:
3) 10+3n=20+5n Set up the problem
-3n -3n Subtract 3n from both sides to get n on one side of the equation.
10 =20-2n
-20 -20 Subtract 20 from both sides to isolate n
-10 =2n
/2 /2 Divide both sides by 2 to isolate n
-5 = n
4) 18=2(b+6) Write down problem
18=2b+12 Distribute
-12 -12 Subtract 12 from both sides to isolate b
6=2b
/2/2 Divide both sides by 2 to isolate b
3=b
Answer:
3) 3x+10 = 5x+20
=> 3x-5x= 20-10
=> -2x= 10
=> x = 10/-2
=> x= -5
4) 2(b+6) = 18
=> 2b +12 = 18
=> 2b = 18-12
=> b= 6/2
=> b = 3

Which statement is true using Cavalieri’s principles ?
Answer:
One of the benefits of Cavalieri's principle is that it allows us to determine the volume of an oblique prism (or oblique cylinder). When dealing with two prisms (or two cylinders), if the base areas are equal and the heights are equal, then the volume is V = Bh regardless of the overall shape.

The temperature of a city is recorded at midnight on the last days of four consecutive months
as -11°C, 5°C, - 8 °C and 15°C. Find the difference between the maximum and the
minimum temperature.
Answer:
26 degrees Celcius
Step-by-step explanation:
The minimum temperature is -11
The maximum temperature is 15
to get from -11 to 0: add 11
to get from 0 to 15: add 15
11+15 = 26

A triangular pane of glass has a height of 42 inches and an area of 336 square inches. What is the length of
the base of the pane?
PLEASE HELP IM BEGGING
Answer:
its 16
Step-by-step explanation:
area for a triangle is 1/2 the base times the height.
IN order to find out the base you need to multiply the area by two and then divide by 42 to find the base. X will represent the base
so
336 *2 = 42x
672= 42x

Factor 10w10 – 19w9 +6w8 completely.
10w10 – 19w9 +6w8 =
Step-by-step explanation:
10w¹⁰ - 19w⁹ + 6w⁸
= w⁸(10w² - 19w + 6)
= w⁸(2w-3)(5w-2)
The value of the equation after factorization is A = w⁸ ( ( 5w - 2 ) ( 2w - 3 ) )
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
A = 10w¹⁰ - 19w⁹ + 6w⁸ be equation (1)
Now , on factorizing the equation , we get
Taking the common factor as w⁸ , we get
A = w⁸ ( 10w² - 19w + 6 )
On further simplification , we get
A = w⁸ ( 10w² - 15w - 4w + 6 )
Now , on factorizing the equation , we get
A = w⁸ ( 5w ( 2w - 3 ) - 2 ( 2w - 3 ) )
And , the equation will be
A = w⁸ ( ( 5w - 2 ) ( 2w - 3 ) )
Therefore , the value of A is w⁸ ( ( 5w - 2 ) ( 2w - 3 ) )
Hence , the equation is A = w⁸ ( ( 5w - 2 ) ( 2w - 3 ) )
