Answer:
X = 62
Step-by-step explanation:
The inside of a triangle is always equal to 180º therefore, you need to add everything up to equal 180. It should look like
(x + 1) + 55 + x = 180
Now you just solve.
Since there are 2 x's you can combine the like terms making them equal 2x
Now the equation should look like 2x + 1 + 55 = 180
Simplify the other like terms: 2x + 56 = 180
Now you want to get x by itself so you subtract 56 from both sides:
2x + 56 = 180
-56 -56
------------------------
2x = 124
Now to finish getting x by itself, divide both sides by 2.
2x = 124
----- ------
2 2
x = 62
FINALLY you plug in x to see if it worked.
(62 + 1) + 55 + 62 = 180

What is 8.865 rounded to the nearest whole number?
Answer:
9
Step-by-step explanation:
8.865 to the nearest whole number is 9, nine is a whole number because there are no decimals following, and since the number "8" is greater than 5, we round up, which would cause it to be 8.900, so to the nearest whole number, it would be 9.

On a class trip with 40 students, 14 are male. What percentage of the class is female?
Hey there!☺
[tex]Answer:\boxed{65\%}[/tex]
[tex]Explanation:[/tex]
Out of the 40 students, 14 are male. To find the amount of females, you have to subtract the amount of males from the amount of total students.
[tex]40-14=26[/tex]
That means there are 26 females. To find the percentage of female students, you have to divide the amount of females by the total number of students.
[tex]26/40=0.65[/tex]
You have to change 0.65 as a percentage by moving the decimal point two places to the right.
[tex]0.65=65\%[/tex]
[tex]65\%[/tex] is your answer.

Susan enlarged a rectangle with a height of 5 cm and a length of 12 on her computer. the length of the new rectangle is 18 cm. find the height of the new rectangle.
the height of the new rectangle is______cm
Answer:
[tex]\huge\boxed{7.5 \ \text{cm}}[/tex]
Step-by-step explanation:
When we scale a rectangle, we multiply both the length and the width by the scale factor - or a constant value.
We can use a proportion to see how much to multiply by, where we have [tex]\frac{\text{height}}{\text{length}}[/tex].
[tex]\frac{5}{12} = \frac{x}{18}[/tex]
To solve for this proportion, we can cross multiply to find the value of x.
[tex]18 \cdot 5 = 90\\\\90 \div 12 = 7.5[/tex]
Therefore the height of the new rectangle is 7.5 cm.

caitlyn has $210 in her savings account and she has to pay her parents $5 each month.Santos has $90 dollars and he saves $5 dollars each month. At this rate, when will Caitlyn and Santos have the same amount of money ? How much will they each have?
Answer:
After about 12 months both Caitlyn and Santos will have the same balance of 150 dollars in their bank account.
Step-by-step explanation:
Caitlyn's saving: -5x+210
Santos' saving: 5x+90
To know when the total amount in their bank account is the same you would need to make these linear equations equal to one another.
-5x+210 = 5x+90
(Add 5x on both sides)
210=10x+90
(Subtract 90 from both sides)
120=10x
(Simplify)
x=12
After about 12 months their total savings should be the same. To check what their balance will be plug the x value of 12 into both of these equations. This should give 150 as your answer for both equations.

– 7
x 7
+ 7
Answer:-7 is the correct answer.
Solution:Because when we'll use -7 then the 7 in the LHS will get cancelled.
x + 7 = 19
or, x + 7 - 7 = 19 - 7
or, x = 12

A short and easy trick is to multiply only the first number since the rest are zero. So, multiply 1 and 1: 1 x 1. What do you get? 1, of course. Then, add the rest of the zero's after that. In 100, there are two zero's. In 100, there are two zero's. What is two plus two? Well: 2 + 2 = 4 so, four zero's. After that, add the 4 zero's after the 1. One is extremely important in this problem. 1, one zero, 10, two zero's, 100, three zero's, 1,000, and finally, four zero's, 10,000. So, the trick is to multiply the one by the other one, get 1, and add the zero's in the other numbers. This can work as long as it is something like: 10 x 10, 100 x 100, 1,000 x 1,000, or even beyond. Just remember to add the zero's!
Note: This only works with digits similar to the ones listed below.
Notice that they all have a 1 at the front and zero('s) behind them.
1) 10 x 10
2) 100 x 100
3) 1,000 x 1,000
This can continue to over 100 zero's per digit!
The solution to the expression is A = 10000
Given data ,
Let the expression be represented as A
Now , the value of A is
Let the first number be represented as p
The value of p = 100
Let the second number be represented as q
The value of q = 100
So, A = pq
On simplifying the equation , we get
A = p multiplied by the value of q
And , A = 100 x 100
A = 10000
Therefore , the value of A is 10000
Hence , the expression is A = 10000
