2x-5y+68x-3y-68=0
70x-8y-68=0
solve from there
Answer Z = -1/4
Step-by-step explanation:
-1/3+2z= -5/6
Add 1/3 to both sides
-1/3+2z+1/3 = -5/6+1/3
Simplify
2z=-1/2
Divide both sides by 2
2z/2 = -1/2/2
Simplify
z = -1/4
When you add any fractions, you need to find a common denominator. In this case they have no common factors so you just multiply them together. First multiply the first fraction by
which gets you
. Then multiply the second fraction by
to get
. Now you can add them together to get
.
(b)
now you can pull out root 2 and get
which equals
Answer:
Multiplication...
Multiplication is just like adding a number to itself multiple times
For example: 3x3 is the same as 3+3+3
Division...
Division is basically splitting up a number between amother lower number, (it might be pretty difficult if you don’t know how to multiply though...)
Start by Rephrasing/re-ordering the equation (9/3 looks like 3*[?] =9)
1) Figure out what Factors equal 9 (by looking at a multiplication table or by adding up like described earlier)
2) You have your answer
(this took way too long to write and you’re probably an idiot if you’re actually in middle school...smh) I can write a different answer if you meant long division, or something else
Answer:
7 whole loaves of bread.
Step-by-step explanation:
Since there are total of 6 locations and each location needs to have the same number of whole loaves of bread we simply need to divide the number of mini-loaves of banana bread by the number of locations like so...
45 / 6 = 7.5
As we can see by the mathematical expression above 45 loaves of bread can be divided into 6, giving each location 7.5 loaves of bread but since each location needs only whole loaves then that would mean that each location would get 7 whole loaves of bread.
