y=5x+1 and y=3x+13
System of equations?
Answer:
(6,31)
Step-by-step explanation:
solve the both equation;
3X+13=5X+1
or, 12=2X
or, X=6
substitute the value of x in the equation;
y=5X+1
or, y=5×6+1
or, y=31
Rhianna was doing research for a report about the highest mountains in the United States. She read that the Grand Teton in Wyoming is about 1.37 × 104 feet high. How should Rhianna write the height of the Grand Teton in standard form on her report?
Answer:
1.37 × 10⁴ feet
Step-by-step explanation:
Standard form is a way or method used in mathematics to write very large or very small numbers in a compact form by raising them to the power of 10 (exponents)
She read that the Grand Teton in Wyoming is about 1.37 × 10⁴ feet high.
The standard form of writing this height = 1.37 × 10⁴ feet.

Answer:
1. -1
2. 25°
3. 26 1/4
Step-by-step explanation:
1. 14-8 is 6, -2 - 4 = -6, 6 ÷ -6 is -1
2. 75 + 80 = 155, 180 - 155 = 25°
3. cross multiply 4/5 = 21/x (4x= 105) = 26 1/4 or 105/4

4. Two times a number added to another number is 25. Three times the first number minus the other number is 20. Find the two numbers.
Answer:9 & 7
Step-by-step explanation:
Let x be the first number and y be the second.
2x + y = 25
3x - y =20
1) Add them together.
5x = 45
x = 9
2) Solve for y.
2(9) + y = 25
y=7
3) Check your work on the other equation.
3(9) - (7) = 20
27 - 7 =20
20 = 20
I have tried to answer it over and over again but never got the right anser
Answer:
#1) 25 degrees #2) 155 degrees #3) 25 degrees #4) 25 degrees #5) 5x+15= 110
Step-by-step explanation:
basically the use the vertical angle relationship to figure it out
that would mean that 4=155 and 3=1 and since the relationship is straight angle pair it means that 155+ x= 180 180-155= 25
5) CDE= FDG this is the vertical angle rule so 5x+15= 8x-42
solve that by adding like terms, 5x-15= 8x-42 +15 by doing adding to both sides it eliminates the 15 because you added it with the like terms, -42 and got -57
-57+8x= 5x now subtract 8 on both sides, -57= -3x divide and it equals 19
now plug that back into the eqaution of 5x+15 5(19)= 95 + 15= 110
The square of 356 is 126,736 and the square of 357 is 127,449. What is 3582? Try to solve this problem without multiplying. Show your work.
Answer:
The problem to get 358² is solved by adding 357 twice and then add 1 to the value of 357²
Step-by-step explanation:
The given information are;
The square of 356 = 126,736
The square of 357 = 127,449
We note that 357² = (356 + 1)² = 356² + 2×356 + 1 = 126,763 + 712 + 1 = 127,449
We can write the above equation as follows;
357² = (356 + 1)² = 356² + 356 + 356 + 1 = 126,763 + 712 + 1 = 127,449
357² = 127,449
Similarly, we have;
358² = (357 + 1)² = 357² + 357 + 357 + 1 = 128,164
358² = 128,164
We can also look at the question as forming squares with tiles
To form the square tile with 358 units per side, we add an extra row and column of 357 tiles each. Completing the figure with an extra tile at the top right or left corner
Therefore, the area of the 358 unit per side square = The area of the 357 unit per side + 357 + 357 + 1 = 128,164

oh god my calculator can't handle this
Step-by-step explanation:
so your answer is 3, take it or leave it
No way is that an actual question that you have to do for school. I tried solving it, but my calculator can't take much. Plus, I tried counting how many 0's and 5's and 3's and 4's there were but my tiny brain can't remember no matter what.
I am bored, though, so I did take away all of the extra numbers. I got 691,360 from solving 10 x 1695 + 334 x 40.

Write the equation -11x+9y=-12 in slope intercept form. what are the slope and y intercept?
Answer:
Step-by-step explanation:
first solve for y (or x) I chose y.
-11 + 9y = -12
(-11) - (-12) = 1
9y = 1
9/1 = 1
y=1, now for x.
-11x + 9 = -12
-12 - 9 = -21
-11x = -21
-21/-11 = -32
x = -32.
A 4-digit number contains at least one even digit. How many such numbers are there? Please help me. I will mark brainliest
Given:
A 4-digit number contains at least one even digit.
To find:
How many such numbers are there?
Solution:
Digits are 0,1,2,3,4,5,6,7,8,9.
Number of odd digits = 5
Number of even digits = 5
4-digit numbers are from 1000 to 9999.
Total number of 4-digit numbers = 9000
Possible ways to get odd digits on all the 4 places is
[tex]5\times 5\times 5\times 5=625[/tex]
It means 625 numbers are their in which all 4 digits are odd.
To find total 4-digit number that contains at least one even digit, subtract the numbers which contains only odd numbers from the total 4-digit numbers.
[tex]9000-625=8375[/tex]
Therefore, total 4-digit number that contains at least one even digit is 8375.

How do you divide a mixed number into a whole number
Answer:
Rules for division with a mixed number and a whole numberThe mixed number is converted into an improper fraction and the whole number is written as a fraction with denominator 1.
2.Division of the fractions is converted into a multiplication operation by multiplying the improper fraction with the reciprocal of the whole number.
3.The resulting fraction, if required, is written as a mixed number in simplest form.I WILL GIVE YOU EXAMPLES AND LET ME JUST HOPE YOU GET IT ;)Example1: Divide. Write your answer as a mixed number in simplest form. 213÷7 Solution Step 1: First, we write the mixed number 213 as an improper fraction 213=(2×3+1)3=73; 7=71 Step 2: The division is converted into multiplication as follows 213÷7=73÷71=73×17 Step 3: Multiplying numerators and denominators 73×17=(7×1)(3×7)=721 Step 4: 721 can be simplified and written as follows 721=13 Step 5: So, 213÷7=13example2: Divide. Write your answer as a mixed number in simplest form. 5÷134 Solution Step 1: First, we write the mixed number 134 as an improper fraction 134=(1×4+3)4=74; 5=51 Step 2: 5÷134=51÷74=51×47 Step 3: Multiplying numerators and denominators 51×47=(5×4)(1×7)=207 Step 4: 207 can be written as a mixed number as follows 207=267 Step 5: So, 5÷134=267OK HOPE THIS HELPS YOU :')PLEASE MARK ME BRILLIANT :3 THANK YOU -
Answer:First step: Write the whole number and the mixed number as improper fractions.
Second step: Write the reciprocal of the divisor, 2/5, and multiply.
Third step: Simplify, if possible. ...
Fourth step: Perform the simple multiplication of the numerators and the denominators.

Subtract x2 - 2x - 6 from - 6x + 5
Find the area of the shape
what is the answer??
Answer: x = -3 + √3 or x = -3 - √3
Step-by-step explanation:
X²+6x+6
now breaking 6x into 2x and 3x we get ,
X²+3x+2x+6
taking x common and 2 common we get ,
x(x+3)+2(x+3)
taking (x+3) common
(x+3) (x+2)
so comparing with zero to get values of x ,
either
x+3=0
x=-3
or x+2=0
x=-2

Professor Burger orders flowers to be delivered to his mother. The flowers cost $59.95, not including tax. A bouquet of flowers is shown. Its price tag reads fifty-nine dollars and ninety-five cents. If there is a 6% sales tax, what is the total cost of the flowers to the nearest cent? Enter the correct answer in the box.
Answer:
$63.55
Step-by-step explanation:
Taxes are charges paid by individuals and enforced by the government in other to fund government spending and various public expenditures.
The flowers cost $59.95 and tax is 6%.
Tax = 6% of flower cost = 0.06 × $59.95 = $3.6
The total cost of the flowers is the sum of tax and the cost of flowers, hence:
Total cost of the flowers = $59.95 + $3.6
Total cost of the flowers = $63.55
