Answer:
0.12
12%
Step-by-step explanation:
SO to find the ones he did incorrectly, you would subtract 50 and 44. This is 6. He got 6 questions wrong. Now divide 6 and 50. This is 0.12.
So decimal: 0.12.
Percent 12%
Answer:
2lb
Step-by-step explanation:
The answer is 2 lb of grass seed. multiply 60 and 20 then divide the product by 300 then multiply the quotient by 1/2.
Answer: 44 dollars
Step-by-step explanation:
so there is two ways to do this so ill show you both and you can see which one is easier for you!
method 1- divide the total amount of tickets by the amount with the cost. Then multiply that number by the cost
20/5=4 4*11=44
method 2- divide the money by the number with the cost. Then multiply it by the total amount of tickets.
11/5=2.2 2.2*20=44
Answer: (1, 4)
Explanation: When using the method of elimination, the goal is to eliminate a variable by either adding or subtracting the 2 equations. For this question, you can choose either to eliminate X or Y. I’ll eliminate X as an example:
In order to eliminate a variable, the same variable in both equations must have the same coefficient.
(1) 3x+y=7
(2) 2x+5y=22
Multiply (1) by 2:
(3) 6x+2y=14
Multiply (2) by 3:
(4) 6x+15y=66
Now that X in both equations has the same coefficient of 6, you can subtract the two equations to officially eliminate the variable and solve for Y:
Subtract (4) from (3):
-13y=-52
y=4
Now that you have the value of Y, substitute that into either one of the equations to get X. I’ll use the first equation as an example:
3x+(4)=7
3x=3
x=1
Therefore, the point of intersection is (1, 4).
Hope this helps シ
