I just tried numbers until I got it.
Directions: Simplify the following expressions. Refer to the rules for signed numbers in solving these problems.
Example: - 4 + 5 = +1 (the signs are different, take the difference (subtract) and place the sign of the larger number)
1. + 2 - (+3) =
2. + 11 + (-10) =
3. 3 + (-5 ) =
4. + 22 - 21 =
5. - 8 - (-44) =
6. -12 - (-6 ) + 3 =
7. + 16 -(-12) =
8. - 36 - (-36) =

Answer:
The temperature difference is equal to 27-(-4)=31.
Step-by-step explanation:
Answer:
31° .
Step-by-step explanation:
we need to calculate the temperature difference between 2 pm and 2 am we can get the difference by subtracting the temperature at 2 am from the temperature at 2 pm
the temperature at 2 pm is 27°
the temperature at 2 am is -4°
the temperature difference between 2 pm and 2 am is:
27° - (-4)° = 31°

A vertical bar is shown at the tip of the arrowhead of the top arrow.
Answer:
The answer is C
Step-by-step explanation:
The answer is C because the arrow is going left from 0 to -3 and then -1 is going to go right.
-3 0

-1
It would be -1 on top but that is how the answer would look like. And the closet to look like that would be C.

What is the area of the triangle.
Answer:
4.44 cm²
Step-by-step explanation:
We can find the area of the outlined triangle by plugging its dimensions into the triangle area formula.
\(A = \frac{1}2 \times \text{base} \times \text{height}\)
\(A = \frac{1}2 \times 6 \times 1.48\)
\(\boxed{A = 4.44 \text{ cm}^2}\)

HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 20 POINTS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! An isosceles trapezoid has an area of 25 square units and a height of 5 units. Find the sum of the bases of the trapezoid.
Complete your work in the space provided or upload a file that can display math symbols if your work requires it.
The formula for the area of a trapezoid is : area = (a + b)/2 x height, where a and b are the top and bottom bases.
Using the provided information you have:
25 = (a + b)/2 x 5
Solving for a+ b the first step is divide both sides by 5:
5 = (a + b)/2
Second step is to multiply both sides by 2:
10 = (a +b)
The sun of the bases would be 10 units.
Answer:
10 units

A golf course has a circular island of grass with a diameter of 15 yards. The mowing company charges $6.50 per square yard. How much will the golf course have to pay to maintain the grass on the circular island?
Answer:
Will cost about $1148.62
Step-by-step explanation:
diameter=15
radius=7.5
area=r^2π
area=7.5^2*π
a=56.25π
this is about 176.71 yardsquared
176.71*6.50=1148.615

One side is 13 (the slanted side of the triangle) one side is 12 (the base) what is the value of x
Answer:
x = 5
Step-by-step explanation:
Given:
a = x
b = 12
c = 13
Work:
a² + b² = c²
x² + 12² = 13²
x² + 144 = 169
x² = 25
\(\sqrt{x^2} =\sqrt{25}\)
x = 5
This is the graph of f(x) = x+A/x+B. The grid lines in the graph are one unit apart. What is the value of A/B
The value of A/B is given as follows:
A/B = -2.
What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:
B = -1 -> as x + B = 0 -> x = -B = -1.
When x = 0, y = -2, hence the value of A is obtained as follows:
A/-1 = -2
A = 2.
Then the division is given as follows:
A/B = 2/-1 = -2.
