Systems of Equations
The solution to a system of equations is the point where the 2 lines intersect.
Q)Examine the graph. Where do the 2 lines intersect?
(1,-2)
The answer is:
(1, -2)Work/explanation:
This system has been solved by the graphing method; both equations have been graphed, and to find the solution, I need to find the point where both graphs intersect. And the graphs are the lines.
The x co-ordinate of the point is the solution for x, and the y co-ordinate of the point is the solution for y.
In our case, the lines intersect at (1, -2), which means that the value of x is 1, and the value of y is -2.

A farmer sells 8.8 kilograms of apples and pears at the farmer's market. 1 4 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?
Answers
Answer: She sold 6.6kg of pears in the market.
Step-by-step explanation:
Weight of apples and pears at the farmer's market.=8.8 kilograms
Weight of apples = 1/4
which is = 1/4 x 8.8kg = 2.2 kg
Weight of Pears =Weight of apples and pears - Weight of apples
= 8.8kg- 2.2kg
= 6.6kg

Judy made 3 pans of brownies for her friends. She cut each pan into 8 equal pieces. Her friends ate 20/8 of the brownies. What fraction of the brownies are left?
Answers
Answer:
13/6
Step-by-step explanation: 8 pieces in 3 pan give us a total of 8/24, then minus 20/8. The writing of this equation is:
20/8- 8/24 or 8/24- 20/8 (both are good)
The common denominator here is 24 since it can divide 8 and divide itself.Since you have 24 as denominator, you'll have to reconvert the fractions above by diving 24 by their previous denominator and multiply it by their numerator:
(24/8) × 20= 60 (numerator of the 1st fraction)
(24/24) × 8= 8 (numerator of the 2nd fraction)
The new fractions are then
60/24 - 8/24= 52/24
We could stop there but since we could find an irrational fraction as an answer, why not do it
52/24 (both divided by 2)= 26/12
26/12 can still be divided so we keep going
26/12 (both divided by 2) = 13/6
13 is a prime number and therefore can be divided only by itself, and 6 cannot be divided by 13 without having a decimal answer.
13/6 is the final answer

What s proportionality in mathematics?
If the corresponding elements of two sequences of numbers, frequently experimental data, have a constant ratio, known as the coefficient of proportionality or proportionality constant, then the two sequences of numbers are proportional or directly proportional.
If equivalent elements in two sequences have a constant product, also known as the coefficient of proportionality, then the two sequences are inversely proportional.
The shadow of a 25 m tall flagpole casts is = 10 m.
Let the height of the office building = x m.
The shadow of a x m tall office building is = 26 m.
From theory of directly proportionality:
25 : 10 = x : 26
25/10 = x/26
x = (25/10)×26 = 65
Hence, the height of the office building is 65 meter.

Jada has a stand in the marketplace where she sells ground cumin. Her weekly expenses are $300, and she sells her cumin at a fixed price per kilogram. If she sells 120 kilograms of cumin, her weekly net profit is $600.
Answers
Answer:
Step-by-step explanation:
The net profit of the marketplace is the difference between the revenue and the expenses. The revenue is the product of number of kilograms sold and the price per kilogram.
Profit = Revenue - Expenses
600 = 120x - 300
The value of x from the equation is 7.5. The answer therefore for the first question is $7.5. Then, the number of kilogram of cumin she needs to sell to cover the expenses is $300/$7.5 and that is equal to 40.

Grace made a dot plot showing the distances she ran each day for two weeks.
She says that she usually runs 7 miles each day because that is the distance that occurs most often.

Dot plot named as ALTDCDistances RunALTDC has number line from 1 to 7. 1 dot on 1, 3 dots on 2, 3 dots on 3, 3 dots on 4 and 4 dots on 7 are given.
The mode, which is (3,4, or 7) ,(is or is not) a typical distance for the data. The median, which is (3.5,4, or 7),(is or is not) a typical distance for the data. The mean, which is (3,4, or 7) ,(is or is not) a typical distance for the data. So, Grace’s reasoning(is or is not ) correct.

1.A five - layer of cake weighs half a kilogram per layer.In each layer,the cake is decorated with icing which weighs 15g.3 candles which weighs 100g each is added.What is the total weight in kilogram of the fully decorated cake?
Answers
Answer: 2.815 kilograms
======================================================
Work Shown:
1 layer = 0.5 kg
5 layers = 5*(0.5 kg) = 2.5 kg
icing = 15 g = 15/1000 = 0.015 kg
1 candle = 100 g = 100/1000 = 0.1 kg
3 candles = 3*(0.1 kg) = 0.3 kg
------------------------
The five layers combine to 2.5 kg. On top of that we have 0.015 kg of icing, and then finally the three candles add 0.3 kg more weight.
The total weight is therefore: 2.5+0.015+0.3 = 2.815 kilograms

Answer:
TUA=123
Step-by-step explanation:
so first we find <TUS in terms of x
so 180-11x-2
178-11x
so now we can use the sum of a triangle's angles which is always 180 to find the angles in triangle TUS
178-11x+5x+10+58=180
178-6x=112
take 178 from both sides
-6x=-66
x=11
so we can do 11x11+2=TUA
TUA=123

i think you made a mistake on "it got colder by 2C." If temperatures get colder, they drop, meaning you subtract it.
also, it said between the hours of 6-10pm, which is three hours, the temperature drops each hour by 3C. so, you multiply 3 to -3, and come up with -9
