Answer:
8+192x5=8+960=968 is your answer
Answer:
<h2>Less than 0.84</h2>
Step-by-step explanation:
- Convert all numbers to decimals
- 85% --> 0.85
- 0.88 --> 0.88
Since these are the top three, the rest of the competitors are less than 0.84.
37493 < x < 37503
it is even....so choices so far are : 37494, 37496, 37498, 37,500, 37,502
rounded to the nearest ten is less then the number....
37494 rounded to the nearest ten = 37490.....it is less then the mystery number
and 37502 rounded to the nearest tens = 37500...it is less then the mystery number
ur other choices, when rounded to the nearest ten are greater then or equal to the mystery number...so they dont work
so now we have 2 choices....37494 and 37502
rounded to the nearest thousand is greater then the mystery number....
37494 rounded to the nearest thousand = 37000...that less then...so this wont work
37502 rounded to the nearest thousand = 38000....thats greater then the mystery number....BINGO....ur answer is : 37502 <==
In this case using the elimination method is actually easier, but the question asks you to use substitution method so....
2x+y= -10
3x-y=0
1st equation: It is better to isolate 2x on both sides because the y is going to be positive no matter what, 2x+y=-10 => y=-2x-10
If you isolated 3x for the 2nd equation, the y will be negative, and you have to divide the whole equation by -1 to make it positive
Now we got y=-2x-10, lets substitute it in the 2nd equation and solve for x:
3x-(-2x-10) = 0
5x+10=0
5x=-10
x=-2
Now lets solve for y:
3(-2)-y=0
-6-y=0
y=-6
Lets see if the same is applicable for 1st equation
2(-2)+(-6)=-10
-10=-10
Yess!!
(-2,-6) is the solution
The answer to the question is explained at the beginning
Hope it helps!
