Answer:
7/11
Step-by-step explanation:
7y +6+4y+13=26
firstly collect like terms
7y+4y+6+13=26
11y+19=26
11y=26-19
11y=7
then divide through by 11
y=7/11
Answer:
70
Step-by-step explanation:
In order to do this, one side of the rectangle will be x+2, and the other will just be x. The x would be representing the width since the length is the width (x) plus two feet (+2). Next, you have to make an equation. So, since it all has to use 16 feet of fencing, you would set the two sides to be added to equal 16. So, it would be: 16=x+2+x. Then, you reduce that, so it would be: 16=2x+2. After that you just solve for x (which means that you want x by itself on one side of the = ). So, you would subtract 2 from both sides. Since 2-2=0, that would make the "+2" go away; since 16-2=14, that would replace the 16. So, your new equation is: 14=2x. After that you just divide both sides by 2 because 2 divided by 2=0. 14/2=7. So, you would end up getting: 7=x as your final answer.
Now, you just put 7 where x was in the sides. So 2x (which was the length) trims into: 2 times 7, which =14 and the x (which was the width) we already figured out was 7. This, the width would be 7, while the length would be 14.
Answer:
yes i can but will have to get back to you in about half a hour just doing maths atm with the teacher
Step-by-step explanation:
Answer: My guess is 15.5 = x
Step by step explanation:
2x + 21
Then divide 2 each side
X + 15.5
