Answer:
3 = ?
Step-by-step explanation:
The triangles are similar, so we can use ratios
15 12 -2
------ = --------------
15+? 12
15 10
------ = --------------
15+? 12
Using cross products
15 * 12 = 10 ( 15+?)
180 = 10 ( 15+?)
Divide each side by 10
18 = 15+?
Subtract 15 from each side
18-15 = 15+?-15
3 = ?

Is 16=3 one, no, or many solutions?
And if the lines were graphed, would they be the same line, intersecting, or parallel
Answers
Answer:
No solutions; parallel
Step-by-step explanation:
The equations x=16 and x=3 both have a slope of 0. So when graphed, they would be parallel and there are no solutions between parallel lines.
Fernando has a prime number of books between 21 and 30 he says that if he takes 4of the books away he will be able to place the same number of books on wacho shelf of this bookcase how Many books does fernando have how many shelves are on the bookcase
Answers
Answer:
29 books ; 5 bookshelfs
Step-by-step explanation:
Solving logically ;
Prime numbers between 21 and 30 = 23, 29
Hence, number of books Fernando has is either 23 or 29
Taking 4 away from the number of books, he'll be able to arrange same number of books on each of his book shelve;
From the statement, we can conclude that :
Subtracting 4 from the number of books Fernando has should give a perfect square
If 23 books
23 - 4 = 19 ; 19 isn't a perfect square
If 29 books :
29 - 4 = 25
Hence, to place the same Number of books on each shelf :
Sqrt(25) = 5
Hence, number of bookshelf = 5

m∠ABU = 70°
Step-by-step explanation:
By applying angle addition postulate,
m∠ABC = m∠UBC + m∠ABU
145° = 75° + m∠ABU
m∠ABU = 145° - 75°
m∠ABU = 70°
Therefore, measure of angle ABU is 70°.

Write the equation of
the circle with diameter
endpoints of (17,-3) and
(-13, 3).
Answers
The equation of the described circle is:
(x - 2)² + y² = 234
How to write the circle equation?Remember that the equation for a circle whose center is (a, b) and has a radius R, is:
(x - a)² + (y - b)² = R²
Here the endpoints of the diameter are (17,-3) and (-13, 3), then the center is at:
( [17 - 13]/2, (-3 + 3)/2)
(2, 0)
And the radius is the distance between the center and any of these points:
R = √( (2 - 17)² + (0 + 3)²)
R = √234
Then the equation is:
(x - 2)² + (y - 0)² = √234²
(x - 2)² + y² = 234

The expression 3(-2m + 5) - 6(-4m - 2) can be written in the form am + b. What is the value of a + b?

-6m + 15 + 24m + 12=

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
First, we can simplify the expression using the distributive property:
3(-2m + 5) - 6(-4m - 2) = -6m + 15 + 24m + 12
Combining like terms, we get:
18m + 27
So, a = 18 and b = 27, which means:
a + b = 18 + 27 = 45
Therefore,
The value of a + b is 45.

Step-by-step explanation:
18/3=6
so Tadashi ate 6 dumpling; the other 12 Able ate
Answer:
12
Step-by-step explanation:
Sine Tadashi eats one third, you have to divide the total amount of dumplings by three.

18-6=12
Abel ate 12 dumplings
