Answer:
x=5
Step-by-step explanation:
So first we want to find x by itself, so we can subtract 4 from both sides:
x=5
That is your simple answer!
Step-by-step explanation:
[tex] \huge{ \sf{x + 4 = 9}}[/tex]
~ Move 4 to right hand side and change it's sign :
⟼ [tex] \huge{ \sf{x = 9 - 4}}[/tex]
~ Subtract 4 from 9
⟼ [tex] \huge{ \sf{x = 5}}[/tex]
[tex] \red{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \bold{ \text{5}}}}}}}[/tex]

What is the sum of an even number plus an odd number? please explain in detail only please, everyone is saying its always odd, others are saying its always even, shouldn't it be both I mean jesus
Answer:
The sum of an even number plus an odd number is odd.
Step-by-step explanation:
The sum of an even number and an odd number is odd.
For example:
2+3=5
11+10=21
51+32=83
The end digit of an even number is always 0, 2, 4, 6, or 8
The end digit of an odd number is 1, 3, 5, 7, or 9.
So if we add only the end digit of an even and an odd number we can find no combination that can give end digit 0, 2, 4, 6, or 8(i.e even).
Hence, the sum of an even number plus an odd number is odd.

Answer:
7/10 and 7/8 are both less than 1.

what is in math solve the following equation 35x-7y=49
Answer:
There is no solution for either variable without further information, as there are two variables given, but only one relationship between them.
You could however use them as a description of a line, which gives every possible solution.
35x - 7y = 49
7y = 35x - 49
y = 5x - 7
We now have an expression describing a line with a slope of five, which crosses the y axis at (0, -7) and the x axis at (1.4, 0)

Find the missing slant height
Answer:
[tex]\ell=\frac{77}{4}[/tex]
Step-by-step explanation:
Because these two cones are similar, we can set up the following proportion:
[tex]\frac{11}{4}=\frac{\ell}{7}[/tex]
Solving, we get:
[tex]\ell=\frac{7\cdot11}{4},\\\ell=\fbox{$\frac{77}{4}$}[/tex].
find the product of the monomial and polynomial xyz*(2x+3y^2-3z^2)
Answer:
2x^2yz + 3xy^3z - 3xyz^3
Step-by-step explanation:
First you must distribute:
xyz(2x) + xyz(3y^2) + xyz(-3z^2)
Then simplify:
2xyxx + 3xyzy^2 - 3xyz * z^2
And finally simplify each term:
2x^2yz + 3xy^3z - 3xyz^3

How can i get an equation that shows the relationship below Plz its for a test for tomorrow X. Y. -2. -6 -1. -3 0. 0 1. 3 2. 6
Answer:
x = 3y
Step-by-step explanation:
In tabular form, the variables are given as;
x y
-2 -6
-1 -3
0 0
1 3
2 6
To determine relationships between variables, you observe the numbers and note how they change
In the first instance, the number; -2 changed to -6. This means it was multiplied by 3.
To confirm it, we check the next set of numbers, -1 and -3. This means it is correct.
The equation showing the relationship between both variables is given as;
x = 3y
The number of fish in a lake decreased by 25% between last year and this year.
Last year there were 60 fish in the lake. What is the population this year?
Answer: This population, the population is 45 fish.
Step-by-step explanation: This problem can be solved by a rule of three.
Last year there were 60 fish in the lake. That was 100, that is, decimal 1.
This year it decreased 25%. So there 100%-25% = 75%, that is decimal 0.75. So
60 fish - 1
x fish - 0.75
This population, the population is 45 fish.
