Rob bought a hat and 3 shirts for $35 . Dan bought 2 hats and a shirt for $20 Which system of equations can be used to find s , the cost of one shirt, and h, the cost of one hat?
Answer:
1x+3y=35, 2x+y=20
x=5, y=10
Step-by-step explanation:
Let x equal the number of hats and y equal number of shirts.
Solve by substitution, elimination, or graphing.
Personally, I just solved by substitution.
Solve for x (or y) in the first equation. Let's do x.
1x+3y=35 goes to 1x=35-3y or just x=35-3y.
Since we have x, plug it in the other equation. 2(35-3y)+y=20. This equals out to y=10, i assume you understand the algebra.
Plug 10 into either equation for y.
1x+3(10)=35 or x+30=35. subtract 30 on each side. X=5.
Can you please solve this? I appreciate it thanks!

What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given that;
The line AE and CD
Now,
The angle sum property to find angle D:
Z + A + B + D = 360° Substitute the given values:
Z + 32 + 58 + D = 360 Simplify:
Z + D = 270 Subtract Z from both sides:
D = 270 - Z
Now, you need to find angle Z. To do that, you can use the fact that opposite angles in a quadrilateral are supplementary, meaning they add up to 180°2. So, angle Z and angle C are supplementary:
Z + C = 180°
You can use the fact that C is an exterior angle of triangle YZX and it is equal to the sum of the opposite interior angles3. Therefore, C = Y + X. Substitute this value:
Z + Y + X = 180°
You are given that Y = 10° and X = 6°. Substitute these values:
Z + 10 + 6 = 180 Simplify:
Z = 164
Now, you can use this value to find angle D:
D = 270 - Z Substitute Z = 164:
D = 270 - 164 Simplify:
D = 106
Therefore, by algebra the answer will be 106°.

Answer:
no
Step-by-step explanation:
a function cant have the same range
Answer:
Functions as Arrow Diagrams When the domain and codomain of a function are finite sets then one can represent the function by an arrow diagram. Remember that an arrow diagram represents a function if exactly one arrow must leave each element of the domain and point to one element in the codomain.

Mrs. Anderson's car can go 464 miles on 16 gallons of gasoline. How many miles
can the car travel on 22 gallons of gasoline?
Answer:
638 miles
Step-by-step explanation:
Key skills needed: Proportions, Unit Rates
1) The car can go 464 miles with 16 gallons of gasoline. We need to find how many miles each gallon gasoline results in.
To find the miles per gallon, we would do 464 miles/16 gallons --> 29 mpg
This means each gallon lets the car run 29 miles.
2) To find out how many miles 22 gallons is, we then do 29 x 22, which is 638 miles.
Therefore, your answer is 638.

Express 2x2 – 3x – 5 as the product of two binomial factors.
Answer:
(2x-5) (x+1)Step-by-step explanation:
Express 2x2 – 3x – 5 as the product of two binomial factors.
factorize the given expression
2x^2 – 3x – 5
2x^2 – 5x+2x – 5
x(2x-5)+ 1 (2x-5)
(2x-5) (x+1)
Hence the expression as the product of two binomial is (2x-5) (x+1)

Which number shows seventy-three hundredths in
standard form?
a) 7,300
b) 7.3
C) 0.73
d) 0.073
The number that shows seventy-three hundredths in standard form will be 0.73.
Standard form simply refers to a number that can be written as a decimal number that's between 1.0 and 10.0 which is then multiplied by a power of 10.Therefore, the number that shows seventy-three hundredths in standard form will be: = 73/100 = 0.73In conclusion, the correct option is 0.73.

Answer:
1: x = 47, y = 902: x = 92, y = 88, z = 923: 284: x = 90, y = 855: 133Explanation:
[1] - Ay = 90 (90 degree angle)
90 - 43 = 47, so x = 47
[2] - Cx = 92 because 180 - 88 = 92
x = 92 and y = 88 because 92 + 88 = 180
[3] - Cx = 28 because 90 - 62 = 28
[4] - Dx = 90 because 180 - 90 = 90
y = 85 because 42 + 53 = 95, 180 - 95 = 85
[5] - Ax = 133 because 180 - 47 = 133

California, the most populous state, has approximately 40,000,000 people living in it. The population of the entire United States is about 3E8 people. About how many times greater is the population of the United States than the population of California?
State operation used and write answer in proper scientific notation (can use e)
Answer: 7.5 E 0
This is the same as saying 7.5 * 10^0
Both of these values convert to the number 7.5; meaning that the population of the US is about 7.5 times greater than the population of CA.
==========================================================
Work Shown:
40,000,000 = 40 million
40,000,000 = 4.0 * 10^7
Note how we move the decimal 7 spots to the right to go from 4.0 to 40,000,000
so the 7 in 10^7 tells us how many spots to move the decimal point in the base number 4.0
The number 4.0*10^7 can be condensed to 4E7. The "E" represents "times 10 to the"
As another example, "3E8" means "3 times 10 to the 8th power" which becomes 3.0*10^8 = 300,000,000 = 300 million
--------------------------
We have these two facts
x = Population of CA = 4 E 7 = 4*10^7y = Population of US = 3 E 8 = 3*10^8We'll divide the two populations to get
y/x = (3E8)/(4E7)
y/x = (3*10^8)/(4*10^7)
y/x = (3/4)*10^(8-7)
y/x = 0.75*10^1
y/x = 7.5
We can see that the population of the US is roughly 7.5 times greater compared to the population of CA.
Convert 7.5 to scientific notation, and we get
7.5 = 7.5*1 = 7.5 * 10^0 = 7.5 E 0
Keep in mind that these are population estimates, and populations change over time.
