If There is a math equation you can use math-way.
Also it would help if you can take a better picture.
Once you take a better picture I promise i will try my best to answer the question.
Answer:
2x + 9
Step-by-step explanation:
Let, "A number", be denoted by the variable, x.
Note the meaning of each part:
"the sum" means addition, or + .
"twice" means multiply by 2
Put the parts together:
The sum of 9 and twice a number
2x + 9 is your amsw34.
Answer:
The correct answer is x = 3 and y = 2.
Step-by-step explanation:
There are many ways to solve systems of equations like this, but I'm going to use substitution. This means taking the value of y given by the second equation and plugging it into the first equation. This is modeled below:
2x - y = 4
2x - (-2x+8) = 4
Now, we can simplify the left side of the equation.
2x + 2x - 8 = 4
4x - 8 = 4
We should add 8 to both sides as the next step.
4x = 12
Now we can divide by 4.
x = 3
To solve for y, we can substitute this value found for x back into either one of our original equations.
y = -2x + 8
y = (-2*3) + 8
y = -6 + 8
y = 2
Therefore, the correct answer is x = 3 and y = 2.
Hope this helps!
Answer:
Multiply both numbers, sorry i can't see the numbers properly or i'd have answer the question myself.
Step-by-step explanation:
Remember area is B times H divided by 2.
So, don;t forget to dicide by 2.
