Solve for m.
-7 + 4m + 10 = 15 -2m
Answer:
M=2
Step-by-step explanation:
m=2 Make sure to move the terms, then collect the like terms, then subtract, then divide both sides by 6
Answer:
m = 2.
Step-by-step explanation:
-7 + 4m + 10 = 15 - 2m
4m + 2m = 15 + 7 - 10
6m = 12
m = 2.

George still has 40 percent of his book to read. If George has read 180 pages, how many pages does he still have to read? How do you know?
Answer: 72
Step-by-step explanation: so you do a line = line method the lines should look like they are fractions.
you do it for the both numbers the percent is always out of 100.
it should look like this
40% ?
--------- = -----------
100% 180
then you cross multiply 40 and 180 and than divide it by 100. your answer should be 72. you later replace the ? with 72
you know this because It is smaller than 180 and its bigger than the number 40.
The number pages left to read is 12 pages.
Given that, George still has 40 percent of his book to read.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Let the total number of pages be x.
Now, x-40% of x=180
⇒ x-0.4x=180
⇒ 0.6x=180
⇒ x=180/0.6
⇒ x=300
So, remaining pages = 300-180=120
Therefore, the number pages left to read is 12 pages.

Choose the function whose graph is given by:
Answer:
A. y = 3sin(x-2) + 1
Step-by-step explanation:
The function whose graph is y= 3 sin (x-2)+1.
What is Function?In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
As, From the graph that is provided to us we observe that,
when x=2 then f(x)=1.
1. y= 3 sin (x-2)+1
When x=2 gives y= 1
So, the equation satisfied.
2. y = 3 sin (x-2)+2
When x= 2 gives y= 2
So, the equation not satisfied.
3. y = 3 cos (x-2)+1
When x= 2 gives y > 1
So, the equation not satisfied.
Thus, the required function is y= 3 sin (x-2)+1.

Can the sides of a triangle have lengths 2, 5, and 5?
Answer:
No, the sides of a triangle cannot have the lengths 2, 5, and 5.
Step-by-step explanation:
Using the right triangle formula, aka. the Pythagorean Theorem, which is [tex]a^{2}+b^{2}=c^{2}[/tex] we need to substitute the sides given with the variables.
[tex]2^{2} +5^{2} =5^{2}[/tex]
Simply to [tex]4+25=25[/tex].
Add 4 to 25.

Answer:
No....
Step-by-step explanation:
it cannot because triangle throrem says that the 2 smaller sides of of triangle must be greater than one side. 2+5 = 7, and 7>5.

Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(−2,1), B(3, 1), C(3,4), and D(−2,4).
What is the perimeter of rectangle ABCD?
_____units
Answer:
The perimeter of rectangle ABCD = 16 units
Step-by-step explanation:
The vertices of the rectangle: A(−2,1), B(3, 1), C(3,4), and D(−2,4).
AB is horizontal, so measre the difference between the x coordinates of A and B.
between -2 and 3 are 5 units.
BC is vertical, so measre the difference between the y coordinates of B and C.
between 4 and 1 is 3 units.
The perimeter = 2 * ( AB + BC )
Substitute AB = 5 and CD = 3
2 * ( 5 + 3 )
2 * 8
The perimeter of rectangle ABCD = 16 units
Answer:
16 units
Step-by-step explanation:
finding the lengths of all sides which are 5,5,3, and 3 then adding them will get you 16 units.

Carlotta collects stamps. She owns f stamps from France and 15 more than twice this amount of American stamps. Which expression represents the number of American stamps that Carlotta owns?
A: f•/•2-15
B: 2f-15
C: f•/•2+15
D: 2f+15
Answer:
D: 2f+15
Step-by-step explanation:
f is the number of stamps from France that Carlotta owns.
Twice this amount is 2f
Then, 15 more than twice this amount is 2f + 15, and this is the expression that represents the number of American stamps that Carlotta owns

Find the value of x and y
Answer:
x = 5
y = 3
Step-by-step explanation:
9x and 45 are alternate interior angles, meaning they're congruent, so set them equal to one another, like so:
9x = 45
Divide both sides by 9:
x = 5
Solving for y, the two sides are of equal length, so set them equal:
6y = 18
Divide both sides by 6:
y = 3
Step-by-step explanation:
By alternate interior angle
9x=45°
x=5°
All parallel sides are equal in parallelogram
6y=18
y=3
