3x - 17 = 2x + 35
Please help
Answer:
[tex]x = 52[/tex]
Step-by-step explanation:
We have the following equation:
[tex]3x -17=2x+35[/tex]
First we simplify the numbers.
[tex]3x -17+17=2x+35+17[/tex]
[tex]3x=2x+52[/tex]
[tex]3x-2x=2x-2x+52[/tex]
[tex]x=52[/tex]
Answer:
x = 52
General Formulas and Concepts:
Order of Operations: BPEMDAS
Step-by-step explanation:
Step 1: Define equation
3x - 17 = 2x + 35
Step 2: Solve for x
Subtract 2x on both sides: x - 17 = 35Add 17 to both sides: x = 52Step 3: Check
Plug in x to verify it's a solution.
Substitute: 3(52) - 17 = 2(52) + 35Multiply: 156 - 17 = 104 + 35Subtract/Add: 139 = 139if Afsheen can read 39 pages of a book in half an hour how much will it take her to finish the book that is 1287 pages
We are given:
Afsheen can read 39 pages in 30 minutes
Time taken by Afsheen to read 1287 pages:
Time taken to read 1 page:
Time taken to read 1 page = time taken to read 39 pages / 39
Time taken to read 1 page = 30 minutes / 39
Time taken to read 1 page = 0.77 minutes
Time taken to read 1287 pages:
Time taken to read 1287 pages = Time taken to read 1 page * 1287
Time taken to read 1287 pages = 0.77 * 1287
Time taken to read 1287 pages = 991 minutes OR 16.52 hours (Approx)
Answer:
in 1 hour = 2×39= 78 pages
so 1287 pages= 1287÷78= 16.5 hours
Step-by-step explanation:
it takes 16. 5 hours that means 16 hours 30 min

When is the sum of two integers equal to zero? Explain.
Answer:
Rule: The sum of any integer and its opposite is equal to zero. Summary: Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.

How do you solve 7,124 ÷ 26 using standard algorithm?
Answer:
274
Step-by-step explanation:
The standard algorithm of multiplication is based on the principle that you already know: multiplying in parts (partial products): simply multiply ones and tens separately, and add.
However, in the standard way the adding is done at the same time as multiplying. The calculation looks more compact and takes less space than the “easy way to multiply” you have learned.(i really think this is correct but I am so so sooo sorry if it's not!!!!)

Four friends are in a swimming race. each Swim as many laps as they can and then tag the next one until they complete 50 laps the first swimmer completes 4/10 of the race. The 2ed completes 8 laps and the third summer complete 22% of the race how many laps will the last member have to swim to complete the race
Answer: The last member has to finish 11 more laps to complete 50 total laps
Step-by-step explanation:
[tex]\frac{4}{10}[/tex] of 50 = 20
2nd swimmer 8
22% of 50 = + 11
39 laps
---------------------------------------------
50 - 39 = 11 laps (4th and last swimmer)

Real numbers: Tick all of the numbers
Rational numbers: Tick all except 3.55687143...
Irrational numbers: Tick 3.55687143...
Integers: Tick 7 and -18
Whole number: Tick 7
Step-by-step explanation:
Real numbers are basically any number.
Rational numbers are numvers which can be converted into a fraction.
Irrational numbers are numbers which cannot be converted into a fraction.
Integers are whole numbers including negative numbers.
Whole numbers are the same as integers but do not include negative numbers.
What does this equal too(2x-5)^2
Answer:
4x² - 20x + 25
Step-by-step explanation:
(2x-5)² means (2x-5)(2x-5)
Expand the brackets.
1. do 2x times 2x = 4x²
2. do 2x times -5 = -10x
3. -5 times 2x = -10x
4. -5 times -5 = 25
Altogether it is 4x² - 10x - 10x + 25
This simplifies to 4x² -20x + 25.

What is Congruence of Triangles?Two or more triangles are said to be congruent if and only if sides and angles of one triangle is equal to the corresponding sides and angles of another triangle.
Given is a proof for the congruence of the lines HG and EG.
Given,
G is the midpoint of KF.
KH ∥ EF
Triangles F E G and K H G are connected at point G.
We have to prove HG ≅ EG.
From the given steps of proof,
we get two angles and the included side of triangle FEG is congruent to corresponding two angles and the included side of triangle KHG.
So by ASA theorem both triangles are congruent.
Hence the missing reason is ASA.

Answer:
x=19
Step-by-step explanation:
4x-3x-12=7
x-12=7
x=7+12
x=19
Answer:
x=19
Step-by-step explanation:
first you would distribute the -3 to the x and the 4 which would give you
4x-3x-12=7
next you would combine like terms (there's always an invisible 1 one front of a variable)
x-12=7
then to get the variable by itself you would add 12 on each side
x=19

Which expression is equivalent to -51-(-60)
Answer:
-51 + 60
Step-by-step explanation:
When subtracting with negative numbers use the "keep, change opposite" skill. Keep your first number which in this case, is -51, then change the subtraction sign to addition and lastly change the sign of your last digit which is (-60) so opposite of that just 60.
