Answer:
y=-3
x=1
(1,-3)
Step-by-step explanation:
5x+4y=-7
-5x-2y=1
Cancel +5x - 5
2y=-6
y=-3
5x-12=-7 or -5x+6=1
5x=5 -5x=-5
x=1 x=1
Answer:
L = 55 in, W = 20 in
Step-by-step explanation:
Hi there!
First we have to set up an equation for the length, which can be written as 3x - 5.
The formula for perimeter of a rectangle is 2l + 2w = p, so we can plug in some values here.
l = 3x - 5
w = x
Now we just have to solve!
When we combine like terms and add ten to both sides, we are left with
, which means x = 20
Using this, that means the width is 20
We can find the perimeter by plugging 20 in for x.
This means the length is 55.
No it is not two ones is two ones and twenty tenths is 200 so 200 would be 2 100 grids and two ones would be two squares
Answer
B
Step-by-step explanation:
because it has to be less than according to the word problem and using common sense I know that if there are more than 1 of a number as an answer choice that means that it is most likely the answer
Answer:
-11°C or 1°C
Step-by-step explanation:
The question said that, by the noon, the temperature changes by 6°C, but it doesn't tell you if it changes for a hotter or colder temperature, so its possible the temperature at the noon to be:
-5 -6 = -11°C
or
-5 +6 = 1°C
To graph the possible temperatures, you have to draw a dot at the numbers -11 and 1
