Mr. Peter's has 80 sheets of colored paper seven of his students need it for a project. how many sheets are left over?
Answer:
Three sheets will be left over.
Step-by-step explanation:
Well, if you have 80 sheets of paper, and seven students need it, you would first divide the 80 sheets to the seven students using the equation 80 ÷ 7 = 11.4. You won't be giving fractions of paper to the students so you would round to 11. If each of the seven students gets 11 sheets of paper, 77 sheets will have been used. 80 - 77 = 3. So, there will be three sheets left over.

Answer:
x=2.5
Step-by-step explanation:
2x+3x-4=x+6
5x-4=x+6
4x=10
x=10/4
x=5/2
x=2.5
Answer:
4x=10 or x= 10/4 or x= 5/2 or x= 2 and 1/2 or also E
Step-by-step explanation:
You can combine like terms by adding 2x and 3x, as they have the same variable with no extra additions onto them. You get 5x.
The current equation should look like 5x-4=x+6
Then you can subtract 1x from both sides, to get rid of the x on the right side to get 4x-4=6
Then you can do a similar operation to add 4 on both sides to get 4x=10.
Finally you can divide both sides by 4 (simplifying to get unit rates of x)
You get x = 10/4
You simplify to get 5/2 and it can simplify to a mixed number if needed which is 2 and 1/2
Can someone write 3^x − 4 = 6 in its logarithmic form?
Answer:
Step-by-step explanation:
get all x terms on one side, giving you 3^x=10
Then, the simple rule is y=b^x becomes x=logb(base)y
b is 3, x is x, and y is 10

write the sentence as an inequality. A number n plus 8 is greater than 11
The Inequality is ___
Solve the inequality
The solution is ___
Answer:
The Inequality n+8>11
n>3
Step-by-step explanation:
The inequality for the given phrase is n+8>11 and its solution is n∈(-∞,3).
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
The given phrase "A number n plus 8 is greater than 11" can be written in the form of inequality as shown below.
A number n plus 8 → n+8A number n plus 8 is greater than 11 → n+8>11Now, the inequality can be solved for the value of n as shown below,
n + 8 > 11
Subtract 8 from both sides of the inequality,
n + 8 - 8 > 11 - 8
n > 3
Hence, the inequality for the given phrase is n+8>11 and its solution is n∈(-∞,3).

In order to convert this equation to Slope-Intercept Form, you must first isolate y What is the first step in isolating y? 4x + 5y = 10
A. Use the Subtraction Property of Equality to subtract 4x from both sides of the equation.
B. Use the Addition Property of Equality to add 5y to both sides of the equation.
C. Use the Division Property of Equality to divide the equation by 4.
D.
Use the Subtraction Property of Equality to subtract 10 from both sides of the equation.
Answer:
A. Use the Subtraction Property of Equality to subtract 4x from both sides of the equation.
Step-by-step explanation:
Given equation is 4x + 5y = 10
we have to convert it in slope intercept form
slope intercept form is given by y = mx + c
now seeing the slop intercept form ,
we can say that
we have to isolate y , for that we have to remove 4x from
4x + 5y = 10 from RHS of the equation
to do that we have to subtract 4x from both side as shown below
4x + 5y - 4x = 10 - 4x
this step is called Subtraction Property of Equality to subtract 4x from both sides of the equation
and hence option A is the correct choice
Answer:
A. Use the Subtraction Property of Equality to subtract 4x from both sides of the equation.

Nature's Best wants to combine nuts they sell for $3.60 a pound with dried fruit they sell for $2.40 a pound to create a trail mix. How much of each snack should they use to make 10 pounds of trail mix that would sell for $3.30 a pound?
--------------
Let amt. of nuts be "x" lbs ; value is 3.60x dollars
-------------
Amt of fruit is "10-x" lbs ; value is 2.4(10-x) = 24-2.4x dollars
----------------------
Amt of mix is 10 lbs ; value is 3.3*10= 33 dollars
------------------------
EQUATION:
value + value = 33 dollars
3.6x + 24-2.4x = 33
1.2x = 9
x = 7.5 lbs (amt of nuts in the mix)
10-x = 2.5 lbs (amt of fruit in the mix)

3 Geometry problems. Please help!
10) These angles are vertical angles.
Whenever two lines intersect, vertical angles are always formed.
Vertical angles are always congruent so we know that b = 43°.
1) Notice that there is a box at the vertex of <EBF.
This tells us that it measures exactly 90 degrees.
Also note that <ABC is a straight angle which means its 180 degrees.
So we have x + 10 + 90 + 2x + x = 180.
First simplify the left to get 4x + 100 = 180.
Solving from here, we find that x = 20.
2) Notice that <AEC and <DEB are vertical angles.
Vertical angles are congruent so we
can setup the equation 3x + 18 = 5x + 6.
First subtract 3x from both sides to get 18 = 2x + 6.
Now subtract 6 from both sides to get 12 = 2x.
Solving from here, we have x = 6.
