Answer:
Step-by-step explanation:
Area of Square = (x+5)²= x² + 10x + 25
Area of rectangle = 2x * x = 2x²
area of rectangle + 1 = Area of square
2x² + 1 = x² + 10x +25
2x² + 1 - x² - 10x - 25 = 0
x² - 10x - 24 = 0
(x - 12) (x + 2) = 0
x - 12 = 0 ; Ignore x + 2 because length wont come in negative
x = 12
Divide the recipe by 4. You need 4 cups of water.
7 video games were in each case.
Step-by-step explanation:
-So, Ricardo has 2 cases of video games with the same amount of games per case.
-He gives 4 games to his brother and is left off with 10 games.
Add 10+4 to get the total amount of games.
Since there are 2 cases, divide the total amount of games (14) by the total amount of video game cases.
This gets us 7, which is the starting amount of video games in each case.
Answer:
i hope this helps
Step-by-step explanation:
if you have 100 people in the room and you interviewed all of them, (for number 6). that means that 70% of these people ate breakfast
70% of the total amount of people you interviewed is 70. That means that 70 people you interviewed, eat breakfast.
Then it also says, "of those 70% of people, 25% eat cereal"
That means 25% of those 70 people eat cereal, or 1/4 of that population does.
0.25 * 70 = 17.5. (of course you cannot have part of a person, but this is an example)
and of the 17.5 people, 30% of them eats it with extra sugar.
so 30% of 17.5 people is 5.25.
that means that there are 5.25 people who eat cereal with extra sugar.
i hope this helps, it took a while for me to try to help with this
i noticed that you made a mistake. the amount of people that eat cereal is 25% of 70% of the people. that means you have to find 0.25 of 0.7 <--- (you multiply not divide)
(0.25x 0.7) = 0.175
Answer:
I believe the answer to this question is: (-3,1) X=-3, Y=1.
