Find the value of x
Answer:
x=35
Step-by-step explanation:
Triangles always add up to 180 degrees, and so do straight lines. so 180-131=49, 49+96=145, 180-145=x, so x=35 degrees
If a numser has an even exponent can it ever be negative when it is simplified?
Explain.
Answer: No, it can never be negative.
==================================================
Explanation:
Consider the expression x^2
If x were some negative number, say x = -3, then
x^2 = (-3)^2 = 9 which is a positive result.
Picking any negative number for x will make x^2 positive.
We can think of it like this
(-3)^2 = (-3)*(-3) = 9
The two negatives multiply to a positive.
This also happens with exponents 4,6,8, etc. Any even exponent will have an even number of negative signs, all of which cancel out.

a rectangular hallway has dimension 6 feet by 18 feet. it is to be tiled with squares tiles, each with the dimension 2/3 feet by 2/3 feet. How many tiles will you need?
We need to find the area of the hallway. To find the area of a rectangle, simply multiply the length and width together.
6ft * 18ft = 108^ft
Now, let's find the area of the square tiles. To find the area of a square, simply square one side.
(2/3ft)^2 = 4/9ft^2
To find out how many square tiles are necessary to tile the hallway, lets divide the area of the hallway by the area of one square.
108ft^2 / (4/9ft^2) = 243 tiles

A surveyor is surveying a street. The surveyor is standing at point P looking down the street at a No Parking sign at point C and a Stop sign at point R. Given PC = 6x-5 meters, PR = 29 meters, CR = 7 meters, and point C is between P and R, what is xin meters?
Answer:
4.5 metresStep-by-step explanation:
If point C is between P and R, then PC+CR = PR.
Given PC = 6x-5
CR = 7 and PR = 29
Required
Find the value of x in metres
Substitute the given values into the formula;
6x-5+7 = 29
6x+2 = 29
subtract 2 from both sides
6x-2+2 = 29-2
6x = 27
Divide both sides by 6
6x/6 = 27/6
x = 27/6
x = 9/2
x = 4.5 metres
Hence the value of x in metres is 4.5metres

How many integers satisfy the inequality (x 2 – 4)(x 2 – 10) < 0?
none
two
four
an infinite number
Answer:
4
Step-by-step explanation:
solution: −√10<x<−2 or 2<x<√10
√10=3.16
-3,-2,2,3
The 2 and -2 are the integers satisfy the inequality.
It is required to find the number of integers .
What is inequality?The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than’, or < ‘less than’.
Given:
For (x²– 4)< 0;
x²<4
By taking the square root of both sides we have,
√x²<√4
x < ±2
x<2 and x<-2
Also,
x²<10
By taking the square root of both sides we get,
√x²<±√10
x < ±√10
x<√10 and x<-√10
The √10 is not an integer but an irrational number. An integer is a whole number (not a fractional number) that can be positive, negative, or zero.
So we can't take the integer of ±√10.
Therefore, the 2 and -2 are the integers satisfy the inequality.

Mercedes takes out a loan for $ 10 , 000 at a simple interest rate of 3.5 % to be paid back in 42 monthly installments. What is the amount of the monthly payments?
Answer:
The amount of monthly installments is $267.30
Step-by-step explanation:
Here, we are interested in calculating the amount of the monthly is installments.
To get the amount of the installments, we need to calculate the sum of the interest and the amount borrowed.
Mathematically,
Simple interest = PRT/100
from the question;
P = principal which is the amount borrowed = $10,000
R = rate = 3.5%
T = time = 42 months = 42/12 = 3.5 years
Substitute these values into the formula for simple interest;
We have ;
S.I = (10,000 * 3.5 * 3.5)/100 = $1,225
So the total amount to
payback = interest + principal = 1225 + 10,000 = 11,225
So the amount of installments will be ;
The amount to payback/number of months
Mathematically that would be ; 11,225/42 = $267.26 which is approximately $267.30 per month

angie read 3 books in 5 days and each book contains 410 pages if angie reads if angie read the same number of books each day how may pages did she read a day
a.90
b.410
c.1,230
d.246
Answer:
D-246 pages.
Step-by-step explanation:
To find the total number of pages, you must do 3*410 which = 1,230. 1,230 is the total number of pages so then you divide that by 5 because there are 5 days so 1,230/5 = 246. So 246 pages per day.
ANSWER 246
410*3(books)=1230 /5(days) =246

1. Translate: A number divided into 4 2. Translate: The sum of 2/3 and a number 3. Translate: Drew is "n" years younger than Joe who is 9 years old
Answer:
1. x/4
2. 2/3+x
3. 9-n
Step-by-step explanation:
1. "A number" is an unknown value, so we set that as the variable. When a number is being divided, it's the divisor in a division problem (the first number)
2. The "sum" is the answer to an addition problem (like how the "quotient" is the answer to a division problem), which is why we know to add. Again, "a number" is the unknown value so we set that as the variable.
3. Because Drew is "n" years younger than Joe, Joe's age - n = Drew's age. The question tells us that Joe is 9 years old, so the expression would be 9-n.
I hope this helps! If it does, a brainliest would be much appreciated :)
The commission earned on the sale of a car can be reprsented by the equation C(p) = 250 + 0.02p, where c
represents the commission and P represents the purchase price of the car.
Jack sold two cars last weekend, one for $115,075 and the other for $21,640. Find his total commission.
Jack's commission=
Answer:
for first car
c = 250 + 0.02*$115,075 = 2551.5
for second car
c= 250 + 0.02*$21,640 = 682.8
total commission= 2551.5 +682.8 = 3234.3

What’s the second step of 2(x+1) =8x-5
Answer:
2(x + 1) = 8x - 5
assuming you already made the first step, the next step is to distribute the 2
2x + 2 = 8x - 5
if you havent made the first step, above is the first step.
the second step would be to combine like terms by subtracting 2x and adding 5 to both sides
7 = 6x
then you would divide both sides by 6
x = 7/6
Joshua wants to make cookies. To make cookies, he needs 1 1/8 cups of flour per batch of cookies. Joshua has 18 cups of flour. How many batches of cookies can he make? *
Answer: He can make 16 batches of cookies.
Step-by-step explanation:
Given: . To make cookies, Joshua needs[tex]1\dfrac18[/tex] cups of flour per batch of cookies.
i.e. 1 Batch requires =[tex]1\dfrac18[/tex] cups of flour
=[tex]\dfrac{9}{8}[/tex] cups [convert mixed fraction to improper fraction.]
Now if 1 batch = [tex]\dfrac{9}{8}[/tex] cups (i)
Then, 1 cup = [tex]\dfrac{8}{9}[/tex] batch. (ii) [Multiply (i) by [tex]\dfrac{8}{9}[/tex] ]
Joshua has 18 cups of flour.
That means , 18 cup = [tex]18\times\dfrac{8}{9}=2\times8=16[/tex] batch. [Multiply (ii) by 18]
∴ He can make 16 batches of cookies.
