Answer:
To round a number to the nearest hundred, you make it into the hundred that is closest. Take the number 246, for example, which is between 200 and 300. It is closer to 200. So 246 rounded to the nearest hundred is 200.
To solve these types of questions, all what you need to do is simply solve for any one of the variables provided above and substitute the solved variable for the other equation. For instance in the first example:
X/2 - 2y = 5
12y + X - 2 = 0
X = 2 - 12y
(2 - 12y)/2 - 2y = 5
(2 - 12y)/2 = 2y + 5
2 - 12y = 2(2y + 5)
2 - 12y = 4y + 10
16 y + 8 = 0
16y = -8
Y =-8/16 = -1/2.
X = 2 - 12(-1/2)
X = 2 + 6
X = 8.
P(X, y) = P(8, -1/2).
Do the same method, for the other questions, except simplify them before doing so.
Answer:
sure.
Step-by-step explanation:
just multiply the multipaction bisector sqaure from 1 to 5 to 6 and then you take a quick then add the 65 to the 9 and get 6
Answer : 96
x – y = 16
--------> equation 1
x is the higher grade and y is the lower grade
We solve the first equation for y
x - y = 16
-y = 16 -x ( divide each term by -1)
y = -16 + x
Now substitute y in second equation
Take common denominator to combine fractions
Add 8 on both sides
Multiply both sides by
x = 96
We know x is the higher grade
96 is the higher grade of Jose’s two tests.
Answer:
The answer is x=1
Step-by-step explanation:
-4(3x+6)+6=-30
-12x-24+6=-30
-12x-18=-30
-12x-18+18=-30+18
-12x=-12
-12x/-12=-12/-12
x=1
