Is –43 − –7 positive or negative?
First, -43-(-7) is the same as -43+7, which is equal to:-
-36
Is the answer positive or negative? The sign in front of 36 will tell us whether the number is positive or negative.
It is negative, because there's a minus sign next to it.

Answer:
y=4
Step-by-step explanation:
The question is asking what is the value of y:
Since all lengths have a dash on them they are all equal :
So 3y = y+8
3y = y + 8
First we subtract y from both sides:
3y-y = y+8-y
2y = 8
Divide both sides by 2:
2y÷2 = 8÷2
y = 4

what is the Median
Answer:
it would be 5.5
Step-by-step explanation:
0.3 1.2 3.7 5.5 5.8 8.1 9.7
Answer:
4.9
Step-by-step explanation:
Median; add up all the numbers then divide by the amount of data points
1.2 + 5.8 + 3.7 + 9.7 + 5.5 + 0.3 + 8.1
7 + 3.7 = 10.7
10.7 + 9.7 = 20.4
20.4 + 5.5 = 25.9
25.9 + 0.3 = 26.2
26.2 + 8.1 = 34.3
34.3 / 7 =4.9
The following three shapes are based only on squares, semicircles, and quarter circles. Find the perimeter and the area of each shaded part.
Answer:
Step-by-step explanation:
The total shaded area = area of the square - area of a circle
= 9^2 - π * 4.5^2
= 17.3827
The 2 shaded parts both have area 8.69 unit^2 ( to nearest hundred)
Perimeter:
The perimeter of the top shaded part
= AB + 1/2 circmference of the circle
= 9 + 1/2 * 2 π r
= 9 + 14.137
= 23.14 units ( to nearest hundredth)
The bottom part has the same perimeter.
Answer:
area: 17.38 cm²perimeter: 46.27 cmStep-by-step explanation:
You want the perimeter and area of the part of a 9 cm square remaining after a semicircle is removed from two opposite sides.
AreaThe shaded area is the area of the 9 cm square less the area of a 9 cm circle. That area is ...
A = s² - π(s/2)² = s²(1 -π/4) . . . . . where s is the side length of the square
A = (9 cm)²(1 -π/4) ≈ 17.38 cm²
The area is about 17.38 cm².
PerimeterThe perimeter is the circumference of the circle plus two sides of the square.
P = C +2s
P = πs +2s = s(π+2)
P = (9 cm)(π+2) ≈ 46.27 cm
The perimeter is about 46.27 cm.

The perimeter of arectangular poultry farm is 38 meter . if 3 meter subtracted from its length and 2 meter from its breadth , the length will be two times the breadth .find the area of the farm
Answer:
82 2/9 square meters
Step-by-step explanation:
The problem statement gives us two relations between length and width. We can write those using equations and the variables L and W for length and widh, in meters.
P = 2(L +W) . . . . . . formula for the perimeter of a rectangle
38 = 2(L +W) . . . . . the perimeter is 38 meters
(L -3) = 2(W -2) . . . . length less 3 is twice the difference of wdith and 2.
__
Dividing the first equation by 2 gives ...
19 = L +W
Solving this for L gives ...
L = 19 -W
Substituting for L in the second equation, we have ...
(19 -W) -3 = 2(W -2)
16 -W = 2W -4 . . . . . . . simplify
20 = 3W . . . . . . . . . . . add W+4
W = 20/3 . . . . . . . . . divide by 3
L = 19 -20/3 = 37/3 . . . . find L from W
__
The area of the farm is the product of length and width:
A = LW = (37/3 m)(20/3 m) = 740/9 m²
A = 82 2/9 m²
The area of the farm is 82 2/9 square meters.
What are all the values of x that make the inequality 8 - 3x < 20 true?
Let's solve this inequality.
First of all, subtract 8 from both sides:-
[tex]\sf{-3x < 20-8}[/tex]
[tex]\sf{-3x < 12}[/tex]
Divide both sides by -3:-
[tex]\sf{x > -4}[/tex]
Notice that the inequality sign changed...
Here's the rule:-
When you multiply/divide both sides by a negative number, you flip the inequality sign; so if we have "less than" it becomes "greater than" and so on...
So these are the values of x that will make the inequality true:-
[tex]\bigstar{\boxed{\pmb{The~numbers~greater~than~-4}}}[/tex]
Well, -3 is greater than 4 :)
Let's plug it in and see if it makes the inequality true:-
-3>-4
Yes, it does make the inequality true :)
note:-Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)

To solve the system of linear equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 by using the linear combination method, Henry decided that he should first multiply the first equation by –3 and then add the two equations together to eliminate the x-terms. When he did so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite number of solutions. To check his answer, he graphed the equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 with his graphing calculator, but he could only see one line. Why is this?
Answer:
Step-by-step explanation:
Both lines have same slope so the graph of both equation will be same and hence it will overlap each other that is why the Henry could only see one line.
Step-by-step explanation:
Given : A system of linear equation 3x - 2y = 4 and 9x - 6y = 12
We have to show whey when Henry graphed the equations 3x-2y=4 and 9x-6y=12 he could only see one line.
Consider the given system of linear equation
3x - 2y = 4 ................(1)
9x - 6y = 12 ..................(2)
Since,
Equation (2) is multiple of equation (1),
3 × ( 3x - 2y = 4) = 9x - 6y = 12
Also the slope of given equations are same
For equation (1),
Differentiate with respect to x, we get,
3-2dy/dx = 0
dy/dx = 3/2
Also for equation (2),
Differentiate with respect to x, we get,
9 - 6dy/dx = 0
dy/dx = 9/6 = 3/2
Since, both lines have same slope so the graph of both equation will be same and hence it will overlap each other.
That is why the Henry could only see one line.

15-9 to find a^2, 4 is b^2, and then pythagorean thereoum, a^2+b^2=c^2.
Answer:
Step-by-step explanation:
The base of the triangle used to solve for x (Pythagorean Theorem) is 15 - 9 = 7
The height of the right triangle is 4 so now you have enought to solve for x
Givens
a = 7
b = 4
c = x
Equation
x^2 = b^2 + a^2
Solution
x^2 = 7^2 + 4^2
x^2 = 49 + 16
x^2 = 65 Take the square root of both sides
√x^2 = √65
Answer x = √65
A plane flies the 1580 km from Cairo to Khartoum.
It departs from Cairo at 1155 and arrives in Khartoum at 1403.
Calculate the average speed of the plane, in kilometres per hour.
speed= distance/ time
= 1580/32/15
=1580/32 ×15
=740.625 km/hrs
time taken by plane:11:55 - 12:00= 5mins
12:00 - 14:03= 2hrs 3mins
total time:
=5 mins + 2hrs 3 mins
= 2hrs 8 mins
= ( 2 + 8/60) hrs
= 2 + 2/15
= 32/15 hrs
If 30% of the 1000 cars on a lot are not hybrids, and 45% are not sedans, how many cars on the lot are hybrid sedans?
The number of cars that are hybrid sedans are = 250 cars
Calculation using a Venn diagramThe value of 30% of 1000 = 30/100× 1000
= 300 cars are not hybrids.
Therefore the number of cars that are hybrids = 300 - x
The value of 45% of 1000 = 45/100 × 1000
= 450 cars are not sedans
Therefore the number of cars that are sedans
= 450 - x
Where X is the cars that are both hybrid and sedans
Using the Venn diagram equation,
1000 = 300 -x + X + 450 - x
1000 = 750 - X
X= 750 - 1000
X = 250 cars
The number of cars that are hybrid is 300 - x where X = 250.
300 - 250 = 50 cars
The number of cars that are sedans is 450 - x. That is,
450 - 250 = 200 cars
Therefore, the cars that are both hybrid and sedans = 250 cars.

3 L of water are shared equally among 5 friends. What fraction of a liter did each friend get?
Explanation: Simply divide 3 over 5. We cannot do much with the fraction since 3/5 can't be reduced. So we leave it as is.
3/5 in decimal form is exactly 0.6 and that converts to 60%, meaning each person gets 60% of a full liter.

How much are bike uses a petrol and oil mixture in the ratio 17:3.
A) how much of each is there in 25 litres of mixture?
By using the given ratio, we will see that 21.25L is petrol and 3.75L of oil.
How much of each component is used?We know that Petrol and Oil is used in a mix with a ratio of 17:3
Then, in 25 liters, then first we need to divide this by 20 (the sum of the two numbers of the ratio), we get:
25 L/20 = 1.25L
So we divided 25 liters in 20 parts. 17 of these parts are petrol, and 3 of these parts are oil
Then:
17*1.25L = 21.25L of petrol
3*1.25L = 3.75L of oil.
