Answer:
4.5
Step-by-step explanation:
if we take -1 and put it in L.H.S it becomes 8+1=9 and then when u put x2 which is x×2 to L.H.S it becomes 9÷2 =4.5
Answer:
4.5
Step-by-step explanation:
First break it apart by taking the x2 and set it aside then add 8 + 1 which is 9.
Next take the 9 and divide it by 2 then you get 4.5.
To double check make sure to multiply 4.5 by 2 just to make sure it gets 9 as the answer.

Ivan read a total of 15 books over 5 months. After belonging to the book club for 8 months, how many books will Ivan have read in all? Solve using unit rates.
Answer:
24 books.
Step-by-step explanation:
Because 15 books divide 5 months would be 3 books so each month is 3 books so 3 books times 3 more months would be 9 books and then you add 15 to 9 and you get 24.

Given the coordinates of point T at (-5,6) and point X at (3,2). What is the
coordinate for the midpoint of line segment TX?
Answer:
The midpoint is
( - 1 , 4 )Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
T( - 5 , 6) and X ( 3 , 2)
The midpoint is
[tex]M = ( \frac{ - 5 + 3}{2} \: , \: \frac{6 + 2}{2} ) \\ = ( - \frac{2}{2} \: , \: \frac{8}{2} )[/tex]

C.
A student's pay of $22 an hour is $7 more than twice the amount the student earns
per hour at an internship. Enter and solve an equation to find the hourly pay of the
internship.
= 2x +
The internship pays $
an hour.
Answer:
The internship pays $7.5 an hour.
Step-by-step explanation:
From the information given, the equation would indicate that the amount the student earns per hour at the intership for two plus seven would be equal to 22:
2x+7=22
Now, you can solve for x:
2x=22-7
2x=15
x=15/2
x=7.5
According to this, the answer is that the internship pays $7.5 an hour.

Mike had 228 dollars to spend on 7 books. After
buying them he had 18 dollars. How much did each book cost ?
Answer:
$30
Step-by-step explanation:
We know that the cost of all of the books was 228 - 18 = 210 dollars because Mike had 18 dollars left over. Assuming that each book cost the same amount, we know that each book costs 210 / 7 = $30.
Answer:
$30
Step-by-step explanation:
Total amount Mike had = $228
Amount remaining = $ 18
Amount spent on books = 228 - 18 = $210
Cost of wach book = 210/7 = $30
Cost of each book is 30 dollars.
show that (-2, 1), (2, -2) and (5,- 2) are the vertics of the right triangle
Step-by-step explanation:
A= (-2,1)
B= (2,-2)
C=(5,2)
slope = y1 - y2/ x1- x2
slope of
AB = -2-1/2-(-2)
= -3/4
BC= 2-(-2)/5-2
= 4/3
AC = -2-1/5-2
= -3/3
=-1
if ABC is a right triangle then AB should be perpendicular to BC
AB x BC = -1
LHS
=-3/4 x 4/3
=-1
= RHS
hence triangle ABC is a right triangle

three times the absolute value of the sum of a number and 6
Answer:
[tex]3|x + 6|[/tex]
Step-by-step explanation:
Required
Get the equivalent of the given statement
Let the number be represented by x
So:
Sum of a number and 6 will be:
[tex]Sum =x + 6[/tex]
The absolute value will be:
[tex]Absolute = |x + 6|[/tex]
Three times this will be:
[tex]Product = 3 * |x + 6|[/tex]
This can be further represented as:
[tex]Product = 3 |x + 6|[/tex]
Hence, the equivalent of the given statement is [tex]3|x + 6|[/tex]

Answer:
102000
Step-by-step explanation:
Answer:
102,000
Explanation:
The number next to 2, which is in the thousands place, is 0 and since the rule for rounding any number less than 5 is to round down, you would round 102,011 to 102,000 for the nearest thousands place.

Answer:
sqrt(29)
Step-by-step explanation:
We can find MN using the Pythagorean theorem
The height is 2 and the length is 5
a^2 + b^2 = c^2
2^2 + 5^2 = MN ^2
4 + 25 = MN^2
29 = MN ^2
taking the square root of each side
sqrt(29) = MN

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be A = 2 (2m) + 4 (4m + 2) = 108
Now , on simplifying the equation , we get
2 (2m) + 4 (4m + 2) = 108
4m + 4 ( 4m ) + 4 ( 2 ) = 108
4m + 16m + 8 = 108
20m + 8 = 108
Subtracting 8 on both sides of the equation , we get
20m = 100
Divide by 20 on both sides of the equation , we get
m = 5
Therefore , the value of m is 5
Hence ,
The value of m from the equation 2 (2m) + 4 (4m + 2) = 108 is m = 5

Andrew used this table to describe several numbers. What error did he make? A.√36 should also be an integer. B. 0.345 should also be an integer. C. −√25 should also be a whole number. D. 0.345 should be a whole number.
Answer:
A rational number is an integer that either doesn't have a decimal or has a decimal that either repeats or terminates (ends). Basically, if these square roots come out to be an integer, they're rational.
The first one comes out to be 42.6028168083, so obviously not rational.
The second one comes out to be 55, so it is rational.
Consider the provided numbers.
√1,815 and √3,025
The value of √1,815 = 48.60281680.....
The value of √3,025 = 55
Now consider the definition of rational and irrational number.
Rational number: A number is said to be rational, if it is in the form of p/q. Where p and q are integer and denominator is not equal to 0.
Irrational number: A number is irrational if it cannot be expressed be expressed by dividing two integers. The decimal expansion of Irrational numbers are neither terminate nor periodic.
The number √1,815 is an irrational number as the decimal expansion of numbers is neither terminate nor periodic.
The number √3,025 is a rational number as it is in the form of p/q.

(-8)(-5) I really need help
Answer: 40
Step-by-step explanation:
For this problem, you need to know the properties of multiplying negative numbers.
- × - = + [negative×negative=positive]
- × + = - [negative×positive=negative]
+ × - = - [positive×negative=negative]
+ × + = + [positive×positive=positive]
Now that we have established the different sign changes, we can multiply -8 and -5. Multiplying -8 and -5 would be the first option. We know that our answer would be positive.
(-8)(-5)=40
