Answer:
348 out of 725
Step-by-step explanation:
This is a ratio question, giving us a sample that we can use to extend the number to all students.
12/25 students play a sport so we want the value of x in x/725
So:
12/25 = x/725
Cross-Multiply:
25x = 8700
Divide by 25 to get x:
348
You can also check by dividing these ratios to see if you get the same number. In this case, you do (.48).
Answer:
Step-by-step explanation:
(smaller triangle below)
(bigger triangle above)
Since you have both triangle, and all lengths you dont need to worry about calculating the square
Add both together
Answer:
The answer is 3⁴
Step-by-step explanation:

Answer:
The correct option is (B)
(B) x-y = 6 , 3x+4y = 4
Step-by-step explanation:
As we can see in the graph given below, both lines intersect at (4, -2), which should be the solution of given equations:
Find the values of x and y for (B);
x - y = 6 ⇒ (i)
3x + 4y = 4 ⇒ (ii)
Lets consider equation (i)
x - y = 6
x = 6 + y
Substitute in equation (ii)
3(6+y) + 4y = 4
18 + 3y + 4y = 4
7y = -14
y = -2
Substitute in equation (i)
x - (-2) = 6
x + 2 = 6
x = 6 - 2
x = 4
As solution of part C is also (4, -2), it represents the graph
You can also find the (x, y) for other options the similar way, which will show you they don't have the same value
Hello! So, with Adian having a goal to lose 5% of his body weight, that means he will still have 95% of it left. The variable "w" represents the current amount of his weight. Multiplying by 1 will still give you his weight. Suppose he weighs 200 pounds. You plug in that as "w". Then, you would multiply that number by 5% (0.05) to see how much he would need to lose. 200 * 0.05 is 10. 200 - 10 is 190. Multiplying any number by 1 will get you to the same number. B and C are out, because they are basically the same equation, even when the "w" in answer choice C is distributed. A is out, because it shows the way the problem would be set up. D does not represent, because 1 is not his weight and it does not give a realistic answer on how much he needs to lose and weigh. Therefore, the answer is D.
