Answer:
7x + 33 -I could be wrong I'm not an expert in maths jus trying to help
Step-by-step explanation:
x + 13 9x-7
so first you need to times both by two because there are two of both sums
2(x+13) so you times both numbers by 2 so
= 2x+26
and do the same with 9x - 7 so
2(9x-7) = 18x - 14
and then you add them together and find the like terms.
Like terms means for example in the equation:
2x + 3x - 4 + 3
the like terms are the two numbers that are the same like 2x and 3x are the same since they are both the same term and since there is a plus sign before the 3x you add them so 5x and then you need to do -4 + 3 = 7 and so the answer is 5x + 7.
In this case its:
2x + 26 + 5x + 7. So the like terms are 2x and +5x and +26 and +7.
So 2x + 5x = 7x and 26 + 7 = 33.
So the final equation is 7x + 33
Hope this helps :D
The 4th option is the correct answer.
Explanation:
Here we will place the opposite of the number of the divisor in the top left box. Now we will bring down the coefficient of the squared term or 2. Now, we will multiply the number in the top left box or 5 with the times of the coefficient of the squared term. This gives 10 and we will place 10 in the second column. This column now contains -1 and 10 and adding these we get 9. Now we will multiply 5 with the result of the second column or 9 to get 45, We will place 45 in the third column which already has 4, and adding both we get 49.
Answer:
r=9/2 or 4.5
Step-by-step explanation:
First of all our goal is to get R by itself
by cross multiplying we get,
(r+3)*3=5r
by distributive property we get
3r+9=5r
substracting 3r from both sides we get
9=2r
by dividing by 2 in both sides we get
r=9/2 or 4.5
