Give your answer as a fraction in its simplest form.
PLEASE HELP
Answer:
2 fifths 2/5
Step-by-step explanation:
10 sided dice has 10 possibilities so 7 8 9 10 are even or greater than 7 that's 4 out of 10 numbers but in simplest form would be 2/5 (2 fifths)
a ballroom had a square dance floor. The area of the floor is 400 square feet. If the length of each side of the square increased by one foot, would its area be a rational number?
Answer:
Yes
Step-by-step explanation:
The area of a square is equal to the length squared.
So, the length of one side of the original floor is √400 which equals 20.
If you increase the length by 1, the area of the dance floor is 21 squared.
21 * 21 is certainly a rational number.
Answer:
Step-by-step explanation:
I think so, yes.
The area of a square is A = s*s where s is the length of the side
s^2 = 400
sqrt(s^2) = sqrt(400)
s = 20
If you increase each dimension by one foot you get 21 * 21 for the area of the new ballroom.
The result is rational. That's because the square root was rational when you found 20.
Area = 21 * 21 = 441 which is rational.
What's the difference between like and unlike algebraic expressions
Answer:
In algebra,
• Like terms are terms having the same literal (variable) with same exponents.
Example: 5y + 8y are like terms because they are both "y".
• Unlike terms are terms having the same variable with different exponents or different variable with same exponents.
Example: 4x + 19y are unlike terms because x and y are two different variables with different coefficients.

Answer:
Step-by-step explanation:
The pet store had 2 cats, 3 dogs, and 1 hamster. How many animal legs did the pet store have?
Answer:
24 legs
Step-by-step explanation:
multiple the amount of cats, dogs and hamsters by 4 and add all three answers together and u get 24
Hey there! Here's your answer.
If you mean literal legs, as in the things you use to walk, the answer would be 24.
Explanation:
First, I added all the animals up.
2 + 3 + 1 = 6
Next, I multipled the answer of the last equation by 4 because each of these animals has 4 legs.
6 x 4 = 24
Finally, I got the answer of 24.
I hope this helps!

Answer:
a. dbc = 66, ABC = 132
b. abd = 52, dbc= 52
Step-by-step explanation:
just remember that bisects means that the angles on either side of the middle line are equal. so for a, dbc = abd and ABC = 2x 66
for b, abd and dbc are equal, so both of them are just 104 divide by two

Find the value of x and KL if K is between J and L.
1. JK = 6 x , KL = 3 x , and JL = 27
2. JK = 2 x , KL = x + 2, and JL = 5 x – 10
Answer:
Step-by-step explanation:
1) JK + KL = JL
6x + 3x = 27
9x = 27
x = 27/9
x = 3
2) JL = JK + KL
5x - 10 = 2x + x + 2 {Combine like terms}
5x - 10 = 3x + 2
Add 10 to both sides
5x = 3x + 2 + 10
5x = 3x + 12
Subtract 3x from both sides
5x - 3x = 12
2x = 12
Divide both sides by 2
x = 12/2
x = 6

if a+b=81 and b+c=23, find 3a+8b+5c
Answer:
358
Step-by-step explanation:
If we multiply the first equation by 3 on both sides we get 3a+3b=243.
If we multiply the second equation by 5 on both sides we get 5b+5c=115.
Adding these equations gives
(3a+3b)+(5b+5c)=243+115
Combine like terms:
3a+8b+5c=358
Another way.
Find numbers to satisfy the criteria.
a+b=81
b+c=23
Choose a=80.
This forces b=1 since 80+1=81.
If b=1 and b+c=23, this forces c=22.
Now plug into 3a+8b+5c.
3(80)+8(1)+5(22)
240+8+110
358
Answer:
128
Step-by-step explanation:
a+b =81
a =81-b
b+c= 23
c =23-b
3a+8b+5c
= 3(81-b) +8b+5(23-b)
=243-3b+8b+ 115-5b
=128+5b-5b
=128

What is expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division.
An expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it. Let us understand how to write expressions. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression.

Solve each equation. Be sure to check for extraneous solution -7= |a-3|/-2
Answer:
a = -11, 17.
Step-by-step explanation:
-7 = |a-3| / -2
Multiply both sides by -2:
|a - 3| = 14
So a - 3 = 14
Giving a = 17
or
a - 3 =- -14
giving a = -11.
Checking these values:
-7 = |17-3| / -2 = 14/-2 = -7
- so a = 17 is a solution.
-7 = |-11-3| / -2 = 14/-2 = -7
so a = -11 is also a solution.
