Answer:
-6+3 because you can distribute the negative sign into the parenthesis and make it a positive.
Answer:
So the answer would be -6+3
Step-by-step explanation:
Here's why:
So think of this strategy when working with these problems
Draw the line connect the sign
This means to convert the -(- into a plus sign, which makes these problems way easier
So that's why the answer is -6+3
Answer = -3
Hope this helps!
Use the definitions and theorems of this section to evaluate and simplify the following expression. Be sure to express answers with positive exponents.
Answer:
x^5(1+x)(1-x+x^2)
Step-by-step explanation:
b^5 +b^8 =
You can easily solve this equation by doing factoring (a fancy word for dividing)
so, factor out the Greatest Common Factor (GCF)
which is
B^5
so in parenthesis write (1+b^3) next to it, think of subtracting the two exponents, and then since theres only 1 thing left after factoring out b^5, you leave a 1 behind.
b^5(1+b^3)
from here, in the parenthesis, you have 2 perfect cubes, 1 and b^3
take the cube root of that which is (1+b)
then use (a+b) which is already done
AND (a^2-ab+b^2) where a is equal to 1, and b is equal to variable b.
so, that would be
x^5(1+x)(1-1x+x^2) ( this is what you should get once you do multiply the square root out to just get constants and coefficients.
That gives us our final answer of x^5(1+x)(1-1x+x^2) because it is in the simplest form possible.

3(x-5)+1=2+x Please put the work!!!!!!!!!!!!!!
Answer:
3(x-5)+1=2+x
3x-15+1=2+x
3x-x=2+15-1
2x=16
x=8
Answer:
x=8
Step-by-step explanation:
3(x-5)+1=2+x
Subtract 1 from both sides.
3(x-5)=1+x
Distribute the 3
3x-15=1+x
Add 15 to both sides.
3x=16+x
Subtract x from both sides.
2x=16
Divide both sides by 2.
x=8

The subtraction problem 11.5−7.2 can be rewritten as the addition problem _[blank]_.
The subtraction expression 11.5−7.2 in the form of addition will be 11.5 + 7.2.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given expression of subtraction is,
E = 11.5−7.2
The expression in the form of addition will be converted by changing the sign of 7.2.
E= 11.5 - (-7.2)
E = 11.5 + 7.2
Therefore, the subtraction expression 11.5−7.2 in the form of addition will be 11.5 + 7.2.

Answer:
74
Step-by-step explanation:
3 3/7 , 4 2/7, 5 1/7, .... 66
=> could be changed into :
24/7, 30/7, 36/7, ...... 462/7
let the numbers = n
462 = 24 + (n-1)(6)
462 = 24 + 6n -6
462 = 6n +18
6n=462-18
6n = 444
n = 444/6 = 74
A bookshop has some fiction and non books. 2/5 of the books are fiction books. Of these, 1/5 are mystery stories. 1/3 of the non fiction books are mystery stories too. What fraction of all the books in the shop are mystery books?
Answer:
20%
Step-by-step explanation:
Step 1: Start by changing the fraction to a decimal by diving the numerator by the denominator (1 divided by 5). That equals 0.2.
Step 2: Change the decimal to a percent by multiplying it by 100%, or moving the decimal two places. That gives you 20%.
Another way of thinking about it is multiplying the numerator by 100%, then dividing that by the denominator (100% divided by 5). This gives you 20%.
Answer: 20%

The cost at a store for a package of pens is $3 and for a three-ring binder
is $4. Write a variable expression for the cost of buying p packages of
pens and b binders. How much would 3 packages of pens and 8 binders
cost?
Hey there! I'm happy to help!
Our question tells us that the number of packages is p and that the number of binders is b.
Each package is $3, so for every p we have, we will have 3 more dollars. So we have 3×p, which is written as 3p.
The same goes for binders. For every binder, we have 4 more dollars, so we have 4×b which is just written as 4b.
An expression is just a number sentence without an equal sign, so something like 1+1 or 7x². The variables are just the letters or symbols that represent an unknown quantity (so 7x² is a variable expression).
Our total cost is going to be the cost of our packages and our binders, so we combine the 3p and 4b we previously came up with, so our expression is 3p+4b.
Now, we can plug in our amounts of each thing into the equation. We will insert our 3 packages in plae of the p and our 8 binders in place of the b to find our cost.
In algebra, you can also write multiplication as a number outside of a number in parentheses so 4(2)=8 for example.
3(3)+4(8)
9+32
41
So, the total cost is $41.

3/2 - 5d = -1/2
calculate the difference
-5d = -2
divide both sides by -5
