Find the test average for test grades or 80, 90, 85, 96.?
Answer:
87.75 or 88
Step-by-step explanation:
To find the average you add the variables together
80+90+85+96=351
And then you take that number and divide by how many variables there are
351÷4=87.75 and you can round up to 88 if you want.

Put each number in an algebraic expression (Don't SOLVE them - Put them in a expression - For EXAMPLE. Four less than five times a number - 11 = 5N-4=11)
1. The product of four and a number is negative twelve.
2. Three decreased by the product of six and a number is equal to negative fifteen.
3. Three multiplied by a number increased by four totals one.
4. The negation of the product of five times a number divided by two is ten.
5. One-third of a number less than nine is equal to seven.
When answering you should have 5 expressions.
Answer:
Step-by-step explanation:
1# Answer:
4x=-12
Step-by-step explanation:
Let a number = X
So
The product of four and a number is negative twelve
4x=-12
2#
3 - 6x = -15 is the equation (it says 3 decreased by the product not the product decreased by 3)
#3
[3(-1)]+4=1
(-3)+4=1
#4
#5
The equation is given by:
9-1/3x = 7
Step-by-step explanation:
Let the number be denoted by x.
Now, we are given a word phrase as follows:
One-third of a number less than nine is equal to seven.
Now this word phrase could be mathematically expressed as a equation by:
one-third of x is: 1/3 x
and this number less than 9 is given by:
9-1/3x
Now, this number is equal to 7.
i.e. we finally have:
9-1/3x = 7

Tyrell worked on
16 - 2(4 + 3x)
what do brackets mean ? they mean that this operation has to be done before everything else in the expression.
as this contains a variable, we cannot fully calculate it, true, but we need to keep this in mind and always treat the content of the brackets as one package.
so, whatever I do from the outside with one part of that package, I have to do also with all the other parts of that package.
so, the multiplication with -2 has to happen with both : 4 and 3x. not just with 4.
therefore, the correct simplification looks like
16 - 8 - 6x
8 - 6x or -6x + 8
Amelia multiplied correctly, but then made a mistake summing things up
10x - 3(4x + 1)
10x - 12x - 3
10x - 12x = -2x
I can't mix the pure constant -3 into the factors of x. that would be like the famous mixing of apples and oranges.
so, the result is

Which best explains whether a triangle with side lengths 2 in., 5 in., and 4 in. is an acute triangle?
The triangle is acute because 22 + 52 > 42.
The triangle is acute because 2 + 4 > 5.
The triangle is not acute because 22 + 42 < 52.
The triangle is not acute because 22 < 42 + 52.
Answer:
The triangle is not acute because 2^2 + 4^2 < 5^2
Step-by-step explanation:
2^2 is side a,
4^2 is side b,
5^2 is side c,
then
c^2 = a^2 + b^2 is right triangle
c^2 > a^2 + b^2 is obtuse
c^2 < a^2 + b^2 is acute
If we insert the numbers into the equation and square them:
c^2 = a^2 + b^2
25 = 4 + 16
25 > 20
This means the triangle is NOT accute, but obtuse
Therefore, it means the triangle is not acute, but obtuse
i.e.,
[tex]a^2 > b^2+c^2\\\\5^2 > 2^2+4^2[/tex]
What is the acute angle?
An angle is formed when two rays meet at a vertex. When this angle measures less than [tex]90[/tex] degree, it is termed an acute angle.
As per the Pythagoras theorem the triangle is acute only if the square of the longest side is less than the sum of the squares of the two smaller sides.
i.e., [tex]a^2 < b^2+c^2[/tex]
where [tex]a,b,c[/tex] are the lengths of the sides of a triangle.
So,
[tex]a^2=5^2\\b^2=2^2\\c^2=4^2[/tex]
Then,
The right triangle is [tex]a^2=b^2+c^2[/tex].
The obtuse triangle is [tex]a^2 > b^2+c^2[/tex]
The acute triangle is [tex]a^2 < b^2 + c^2[/tex]
i.e.,
[tex]5^2 = 2^2+4^2\\\\25=4+16\\\\25 > 20[/tex]
Hence, this means the triangle is not acute, but obtuse.

if you need 180g of flour for 24 cookies how much flour is needed for 200
Answer:
1500g
Step-by-step explanation:
First, divide 200 by 24 so that you can have a common ratio. This would get you 8.333... Then multiply 8.333... to 180. This would get you the answer of 1500 g. Hope this helps :)
The amount of flour to make 200 cookies will be 1500 grams.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
If you need 180g of flour for 24 cookies.
Let 'x' be the amount of flour. Then the ratio of the flour to cookies will be constant.
x / 200 = 180 / 24
x = 200 x 180 / 24
x = 1500 grams
The amount of flour to make 200 cookies will be 1500 grams.

Need help Fast!!!Part A: Max rented a boat that costs $225 for 2 days. If he rents the same boat for 5 days, he has to pay a total rent of $480.
Write an equation in the slope-intercept form to represent the total rent (y) that Max has to pay for renting the boat for x days. (Hint.....use point slope form...then change to slope-intercept form) (6 points)
Part B: Write the equation obtained in Part A using function notation.(2 points)
(10 points)
Answer:
Part A:
The Standard Form equation of a line has the following formula:
Ax+By=C, where A, B, and C are integers, and A is non-negative.
We will assume that when renting a boat Sam paid fixed cost and rental charge per day.
y = the total rent
x = the number of days
Sam rented a boat at $225 for 2 days would mean:
y = 225 when x = 2 or if we plug into Ax+By=C:
2A + 225B = C since A is non-negative we divide both sides by A
2 + (B/A)225 = C/A
He rents the same boat for 5 days, he has to pay a total rent of $480 means:
y = 480 when x = 5 days
5A + 480B = C since A is non-negative we divide both sides by A
5 + (B/A)480 = C/A
Now we have:
2 + (B/A)225 = C/A
5 + (B/A)480 = C/A
Lets denote s = B/A and t = C/A. Now we can write the following system of equations:
2 + 225s = t
5 + 480s = t
........
click here to see the system of equations solved for s and t
........
s = -1/85
t = -11/17 = -55/85
Now we can go back to:
B/A = -1/85 and C/A = -55/85
A = 85, B = -1, C = -55
The standard equation is:
85x - y = -55
Part B:
Using the equation 85x - y = -55 we solve for y
.......
click here to see the equation solved for y
........
y = 85x + 55
or in function notion y = f(x)
f(x) = 85x + 55

Answer:
The ___a_ value of the quadratic function determines whether the parabola opens upward or downward.
Answer:
The 'a' value.
Step-by-step explanation:
The general quadradic equation is:
[tex]ax^2 + bx + c; \text{ } a\neq 0[/tex]
If the value of a is greater than 0, then the parabola would open upward. If the value of a is less than 0, then the parabola would open downward.
