9 x 3.5 = 31.5
2 x 2 = 4
2 x 2 = 4 / 2 = 2
2 x 5 = 10/ 2 = 5
31.5 + 4 + 2 + 5 = 42.5^2
Answer: 10, 1/10, 2/5
Step-by-step explanation:
I believe the answer is 25 because it says that 2)m=5 or it may be 30 because 5times 2 equals 10 and 10plus 20 gives you 30
3x+10y=48
7x+4y=54
multiply the first equation by 2 and the 2nd equation by 5 to remove y
6x+20y=96
35x+20y=270
29x=174
x=6
substitute to any equation
7x+4y=54
42+4y=54
4y=12
y=3
the value of x is 6 and the value of y is 3
