Answer:
Number = 92
Step-by-step explanation:
Let the unit digit is x and that of tens digit is y.
ATQ,
x+y = 11 ....(1)
The unit's digit is 7 less than the ten's digit
x = y-7 ...(2)
Put the value of x from equation (2) in (1)
y-7+y = 11
2x-7 = 11
2x = 11+7
2x = 18
x = 9
Put the value of x in equation (1)
9+y = 11
y = 2
Hence, the number is 92.
When solving equations we always undo the addition or subtraction first.

vector u = <2,5> . Describe how you would use a graphical method to add vector u to vector v (shown in the graph). Then, write the resultant vector in the component form.
Answer:
Step-by-step explanation:
Draw vector u in standard position. To add u to v, shift u three units to the right and one unit up so its initial point coincides with the terminal point of v. Use a dotted line to depict the shifted vector u. Finally, draw the resulting vector with its initial point at the origin and endpoint at v + u. The component form of this resulting vector is <5, -4>.

Does 6(3-5w)=5(4-2w)-20w have one solution, no solution, or infinitely many solutions?
Answer:
infinite
Step-by-step explanation:
trust me I would know im a smart man in college
Two or more expressions with an Equal sign is called as Equation.6(3-5w)=5(4-2w)-20w have no solution
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 6 times of three minus five w equal to five times of four minus two w minus twenty w.
6(3-5w)=5(4-2w)-20w
Apply distributive law on LHS side
6(3)-6(5w)=5(4)-5(2w)-20w
18-30w=20-10w-20w
Let us take all the variable w terms to one side
18-20=30w-10w-20w
-2=0
Hence based on the given equation , it has no solution.

Klara picks a number. She rounds to the nearest hundred. She rounds tot the nearest thousand. She rounds the number to the nearest ten thousand. All three times, the result is the same. Which choice could be klara's number?
Answer with step-by-step explanation:
The question does not seem complete, but I'll try to make some explanations.
When you want to round a number, there are some rules.
1. If the number you are rounding is followed by 5, 6, 7, 8, 9, then round the number up, that is add 1 to it.
2. If the number you are rounding is followed by 0, 1, 2, 3, 4, then round the number down, that is add 0.
Now if given a number and you are asked to round to the nearest 100, 1 000, 10 000 and so on, then for nearest 100, count 2 numbers from the back. Whatever number you stop at, that is the number you are to round. For 1000 count 3, for 10 000 count 4 and so on.
Since Kiara is having the same value after rounding, it means she picked a number that has zeros after the 10 000th value
Let's assume she picked: 70 000
Rounding that number to nearest 100, 1000 and 10000 gives the same number which is
70 000.

Answer:
The marked angle GEF is 25
Step-by-step explanation:
Here, we want to calculate the value of the marked angle
Mathematically, a diagram should do justice to this
Please check the attachment for the diagram
The theorem we want to use is that the sum of opposite interior angles equals the exterior angle
Thus, mathematically;
2x + 1 + x + 19 = 6x + 2
3x + 20 = 6x + 2
6x-3x = 20-2
3x = 18
x = 18/3
x = 6
The angle marked GEF is x + 19
That will be 6 + 19 = 25

Which of the following best approximates the line of best fit?
Step-by-step explanation:
Line C does not follow the trend of points. Lines A and B have an excess number of points above their lines. Only Line D has a relative equal number of points above and below the line.
The answer is D.
The solution is, The graph that best approximates the line of best fit is option D.
Here, we have,
we know that,
Line of Best Fit:
This refers to the line that is used in a scatter plot to show and indicate a relationship between the points so that the number of points above the line is equal to the points below the point.
Line C does not follow the trend of points. Lines A and B have an excess number of points above their lines. Only Line D has a relative equal number of points above and below the line.
Hence, from the given illustration of graphs, we can see that using the eyeball method, we can see that the number of points in option D is best balanced between the line above and below.
The answer is D.

This equation has one solution.
5(0-1) + 3y = 7(x + 1)
What is the solution?
Answer:
7x - 3y = -12
Step-by-step explanation:
5(0-1) + 3y = 7(x + 1)
using BODMAS to solve
5(-1) + 3y = 7(x + 1)
-5 + 3y = 7x + 7
7x - 3y = -5 - 7
7x - 3y = -12

The first humor bookshelf in the section of a library can hold 2296, books. The bookshelf has 7 shelves. Shelves. Each shelf can hold the same number of books. How many books can each shelf hold? Write an equation to help solve this problem.
They said each shelf can hold the same number of books
And we have 7 shelves
Total number of books = 2296
Hence:
The number of books each shelf can hold = 2296 books/7 Shelves
= 328 books
Hence, each shelf can hold 328 books
An equation to solve this problem =
Number of books can be represented by x
Hence:
7x = 2296

Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
- 6x + 2y = 18 ( add 6x to both sides )
2y = 6x + 18 ( divide all terms by 2 )
y = 3x + 9 ← in slope- intercept form
