Answer:
To multiply two minus numbers they will result as a positive number.
the product of any numbers when there is a negtive will always have 2 negtives invlved form three numbers including the answer.
-4 x -1.5 is the same as 4 x 1.5
the answer is 6
Three numbers like -1 x 4 will also be 2 numbers of negative.
= -4
We change this to -4 x 1.5 and shows the answer as -6
But the question had 2 negative numbers already and the answer is just positive 6.
Answer:
A; infinitely many solutions
Step-by-step explanation:
first, let's simplify the first equation to make it simpler.
divide both sides by 5
y=3x-8
new system
y=3x-8
y=3x-8
as you can see, they are the same.
not mandatory but useful!⬇⬇⬇⬇
just to be more clear, let's substitute them. since they're both already in y=, we can make them both set to each other.
3x-8=3x-8
add 8 to both sides; subtract 3x from one side
0=0
the answer is A, Infinitely many solutions.

Answer: 5, -4, 2.6, and 100
Step-by-step explanation:
Answer:
1.2218 atm
Step-by-step explanation:
From ideal gas formula,
PV=nRT
Where n= number of moles
V= volume
T= temperature=25.0°C
= (273 + 25) = 298 K
R= gas constant = 0.082 l atm /K mol.
Making P subject of formula we have
P= [nRT] /V
Then substitute the values we have
P= [0.5 x 0.082 x 298] / 10
P= 1.2218 atm
