Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
-4p + q = -5
p - q = 7
Step 2: Rewrite Systems
p - q = 7
Add q on both sides: p = q + 7Step 3: Redefine Systems
-4p + q = -5
p = q + 7
Step 4: Solve for q
Substitution
Substitute in p: -4(q + 7) + q = -5Distribute -4: -4q - 28 + q = -5Combine like terms: -3q - 28 = -5Isolate q term: -3q = 23Isolate q: q = -23/3Step 5: Solve for p
Define equation: p - q = 7Substitute in q: p - (-23/3) = 7Simplify: p + 23/3 = 7Isolate p: p = -2/3-4(2) + 3 = -5
8 - 1 = 7

The half-life of Einsteinium 253 is 20.5 days. If you start with 5g
of Es-253, how many grams will you have after 31 days?
Answers
Answer:
1.753 g
Step-by-step explanation:
Half life of Einsteinium = 20.5 days
Time elapsed = 31 days
Initial quantity of the substance = 5g
The formula to apply is;
[tex]N( t )=N_o( \frac{1}{2} )^{\frac{t}{t0.5} }[/tex]
Where
N(t)=quantity of a substance remaining
No =Initial quantity of the substance = 5g
t= time elapsed=31 days
t1/2 = half life of the substance= 20.5 days
N(t)=5 * {1/2} ^ {31/20.5}
N{t} = 5 * {0.5}^1.5
N{t} = 5*0.3506
N{t} =1.753 g

Answers
Answer: B on Edge2021
Step-by-step explanation:
Just took the test
Probability that a randomly selected customer from Satellite Company Y watches recorded shows more often than live television is 59%.
What is Probability?Probability is simply the likelihood that something will occur.
Probability of customer randomly selected from Company Y:
Probability(Y)=Recorded/(Live+Recorded)
Probability(Y)=94/(65+94)
Probability(Y)= 94/159
Probability(Y)= 0.59119 ×100
Probability(Y)= 59.12%
Probability(Y)= 59% (Approximately)
Therefore, probability of a randomly selected customer from Satellite Company Y is 59%.

Solve by using substitution. Express your answer as an ordered pair.
Answers
Greetings.
Solving by substitution, we can substitute either y-term or x-term. For a fast and better way, I recommend you to substituting x-term.
[tex] - x + 3y = 7 \\ x - 4y = - 10[/tex]
Because for x-term, we don't have to move the coefficient to another side as the coefficient for x-terms are both - 1 and 1.
What we need to do is that we move everything to another side excluding x-term.
I will be moving the second equation to another side.
[tex]x = - 10 + 4y[/tex]
Now our x-term for the seco d equation is - 10+4y.
Substitute x =-10+4y in the first equation.
[tex] - ( - 10 + 4y) + 3y = 7[/tex]
We should get like this. Then we distribute the negative sign in the brackets.
[tex]10 - 4y + 3y = 7[/tex]
Remember that negative multiplying negative equal positive.
[tex] - y + 10 = 7[/tex]
Subtract as we get -y then we move 10 to another side, leaving y as the subject.
[tex] - y = 7 - 10 \\ - y = - 3 \\ y = \frac{ - 3}{ - 1} \\ y = 3[/tex]
Also negative dividing negative equal positive as well. We have the y-value but because it is the two equations. We need to find the x-value as well.
Therefore, substituting y-value in any given equations. It is better to substitute y-value in the equation with less coefficient value.
I will be substituting y-value in the first equation.
[tex] - x + 3y = 7[/tex]
Substitute y = 3 in the equation.
[tex] - x + 3(3) = 7 \\ - x + 9 = 7 \\ - x = 7 - 9 \\ - x = - 2 \\ x = \frac{ - 2}{ - 1} \\ x = 2[/tex]
