2/5=4/10=12/30 1/3=10/30 12/30+10/30=22/30 22/30=11/15
The number in the blank box should be 44 because it said that "3 times x and 4 times y is 44".
You need to multiply the first equation by 3:
3x + 3y = 39.
Then, subtract the first equation from the second equation:
3x - 3x = 0
4y - 3y = y
44 - 39 = 5
Your new equation should look like this: y = 5
Now, substitute y = 5 into the first original equation:
x + 5 = 13
x = 8
Ans. (x, y) = (8, 5)
Answer: A 300 inches
Step-by-step explanation:
Area (a) = 90,000
Side = √a

Side = 300
Answer:
10:12
15:18
20:24
25:30
Step-by-step explanation:
you could just multiply 5 and 6 by the same number so you would get ratios that are equal to each other so for example for 10:12 5 and 6 is getting multiplied by 2
Answer:
The answer is 94.8 m
Step-by-step explanation:
Area of a square is a²
So, 23.7² = 561.69 m²
The side of the square is equal to 23.7 m
Perimeter of a square is the side multiplied by 4
So we have that 23.7 x 4 = 94.8 m
