Answer:
x> -1/2
Step-by-step explanation:
B. because the hundreths place is the one two places to the right from the decimal, and you keep it the same if the number next to it is smaller.
Answer:
-<u>One Equation</u>: is set equal to a variable
Example:
y = 2x + 1
x + 3y = -12
You already have y, plug it back into x + 3y = -12
x + 3(2x + 1) = -12
x + 6x + 3 = -12
7x + 3 = -12
(Subtract 3 from each side)
7x = -15
(Divide by 7)
x = - 2.14
-<u>No Equation</u>: is set equal to a variable
Example:
2x + y = 10
4× + 2y = -3
Subtract 2x from each side of 2x + y = 10, you should get y= -2x + 10. Now that you have found y, substitute y into 4x+ 2y = -3.
4x + 2(-2x + 10) = -3
4x + -4x + 20 = -3
(Subtract 20 from each side)
4x + -4x = -23
(Add 4x and -4x)
0 = -23
No Solution
<u>-Both</u><u> </u><u>Equations</u>: are set equal to a variable
Example:
y = x + 5
y = -x + 3
(you already have y so plug it into the other equation to solve for x)
-x + 3 = x + 5
(Add -x on both sides)
3 = 2x + 5
(subtract 5 from both sides)
-2 = 2x
(Divide by 2 on each side)
x = -1

Answer:
1 1/2
Step-by-step explanation:
We need to convert all of these into one denominator. 1 1/4 needs to be converted into 12ths. 4 x 3 = 12 1 x 3 = 3. Our new fraction instead of 1 1/4 is 1 3/12.
Which is closer to the whole number?
1 1/12 is 1/12 away from a whole number
1 3/12 is 3/12 away from a whole number
1 5/12 is 5/12 away from a whole number
Hope this helps!
Answer:
40
Step-by-step explanation:
you have to multiply x by 4 to get y when x=4 and y=16. so if x=10, then you have to multiply what x is (10) by 4 because there is a common ratio.
hope this helps!! please give brainliest!!!!!!
