Answer:
number is 10
Step-by-step explanation:
let n be the number, then 4 more than the number is n + 4, thus
n(n + 4) = 140 , that is
n² + 4n = 140 ( subtract 140 from both sides )
n² + 4n - 140 = 0
Consider the factors of the constant term (- 140) which sum to give the coefficient of the n- term (+ 4)
The factors are + 14 and - 10 , since
14 × - 10 = - 140 and 14 - 10 = + 4 , thus
(n + 14)(n - 10) = 0 ← in factored form
Equate each factor to zero and solve for n
n + 14 = 0 ⇒ n = - 14
n - 10 = 0 ⇒ n = 10
Since n is a whole number the the required number is 10

For a field trip 5 students rode in cars and
the rest filled three buses. How many
students were in each bus if 107 students
were on the trip?
Answer: 52 students were in the bus.
Step-by-step explanation: First, you start with the equation:
9x+4=472
Since four students rode in cars, you want to eliminate this part of the problem to find how many students actually rode in the buses.
So you would subtract 4 from both sides and get: 9x=468
Finally, you would divide both sides by 9 and get 52 students on each bus
How do the measures of the side lengths of AABCcompare with those of AA'B'C' when AA'B'C' coincides with the other three triangles?
What can you say about the preservation of the side lengths of a shape during a rotation?
Answer:
The angle measures of ABC and the other triangles are the same measures, and the side lengths in ABC and the other triangles are the same lengths when ABC coincides with them. It appears that angle measures and side lengths are both preserved when ABC is rotated.

The elevation we call sea level is actually the average level of the sea. This means that at average sea level, the elevation is zero. In reality, the level of the sea rises and falls in what are called tides. Low tide is the point of lowest sea level in a tidal period. High tide is the point of highest sea level in a tidal period. The height above or below average sea level is called elevation. An elevation below sea level is considered a negative value, while an elevation above sea level is positive.
Winston lives near the ocean. He regularly brings an altimeter to the beach to measure the elevation of the ocean’s surface. You will use the data Winston gathered to complete tasks about the rising and falling of the ocean’s surface. When necessary, sketch a diagram of the situation on a separate sheet of paper to assist you.
On Monday at 1 p.m., when the ocean’s surface was at an elevation of 2.2 feet, Winston went to a surf shop that was 8.2 feet above the ocean’s surface. At 7 p.m. when the ocean’s surface was at an elevation of -2.4 feet, Winston ate dinner at a restaurant whose deck was 10 feet above the ocean’s surface.
What was the distance between the deck and the ocean’s surface at 1 p.m.? Which was higher, the deck or the ocean?
What was the distance between the surf shop and the ocean’s surface at 7 p.m.? Which was higher, the surf shop or the ocean?
Answer:
The surf shop was higher and the distance would be 12.8 feet above the oceans surface.

-(1+7x)-6(-7-x)=36 what is x equal to
Answer:
x = 5
Step-by-step explanation:
Step 1: Write equation
-(1 + 7x) - 6(-7 - x) = 36
Step 2: Solve for x
Distribute: -1 - 7x + 42 + 6x = 36Combine like terms: -x + 41 = 36Subtract 41 on both sides: -x = -5Divide both sides: x = 5Step 3: Check
Plug in x to verify it's a solution.
-(1 + 7(5)) - 6(-7 - 5) = 36
-(1 + 35) - 6(-12) = 36
-(36) + 72 = 36
-36 + 72 = 36
36 = 36

f(x) = 3x + 2
g(x) = 2x^2 - 4x
h(x) = x^2 - x + 7
Find f[g(5)]
A. 92
B. 2
C. 30
D. 242
Answer:
A
Step-by-step explanation:
Evaluate g(5), then use the value obtained to evaluate f(x) , that is
g(5) = 2(5)² - 4(5) = 2(25) - 20 = 50 - 20 = 30, then
f(30) = 3(30) + 2 = 90 + 2 = 92

At Store #1 for $625 you can buy 25 pairs of shoes. How much will you pay for 31 pairs of shoes?
Answer:
Step-by-step explanation:
25 pairs of shoes = $625
You need to find how much each pair of shoes cost.
1 pair of shoes = [tex]\frac{625}{25}[/tex] = $25
So for 31 pairs of shoes, you just multiply by 25
31 pairs of shoes = 25 x 31 = $?

The school's Environmental Science Club has $500 of funds. Each time they go on a field trip, it costs
them $80. Write an algebraic expression that represents the money the club has after going on field
trips. Use the Math equation tool va to answer the question.
Given:
Total fund = $500
cost of each trip = $80
To find:
The an algebraic expression that represents the money the club has after going on field trips.
Solution:
Let x be the number of field trips.
Cost of 1 field trip = $80
Cost of x field trip = $80x
We have, Total fund = $500.
So, the money the club has after going on field trips is
[tex]\text{Remaining money}=500-80x[/tex]
Therefore, the money the club has after going on field trips is $(500-80x).

The function f(x) = 100x + 300 represents the cost for the physics club to attend science weekend at
the local theme park where x represents the number of students who attend. At least 4 students but
no more than 9 students will attend the fieldtrip due to transportation and chaperone restrictions.
9. Is this a discrete or continuous situation? Explain.
Answer:
Discrete
Step-by-step explanation:
Given the function:
f(x) = 100x + 300
Where ;
x = number of attendees
At least 4 students but no more than 9 students will attend the fieldtrip due to transportation and chaperone restrictions
Range of attendees :
4 ≤ x ≤ 9
Is this a discrete or continuous situation?
It is a discrete because the number of students who will attend the science weekend are finite and countable.
The number of attendees range from:
4, 5, 6, 7, 8 and 9.
