Answer:
Step-by-step explanation:
The 9 in 95 tells us how many tens are in the number 95.417; the 5 tells us how many ones, and the 4 how many tenths. And so on.
Thus,
95.417 = 9*10^1 + 5*10^0 + 4*10^(-1) + 1*10^(-2) + 7*10^(-3)
is 95.417 in expanded form, with each digit multiplying a power of 10.
Answer:
x = -2, y = 3
Step-by-step explanation:
2x + 3y = 5
5x - 2y = -16
In order to find the value of a variable, we must eliminate the other variable by multiplying the equations to get the same coefficient.
We can multiply the first equation by 5 and the second one by 2 to get the same coefficient for x, the equations then become:
10x + 15y = 25
10x - 4y = -32
Now we can subtract:
19y = 57
y = 3
Since we know the value of y, we can substitute it into one of the original equations:
2x + 3(3) = 5
2x + 9 = 5
2x = -4
x = -2
