Answer:
The answer is c :" Mary should isolate the x term because she can then simplify the remaining expression to solve for x."
Step-by-step explanation:
From the equation as written below,
(x-4)(x-1)= 60
the first step is expansion of the bracket, thus we have,
x2-4x-x+4=3(2)60
which equals
x2-5x+4=3(2)60
then the next step should be to isolate x terms to be on one side of the equation while she continues solving for x,
x2-5x= 3(2)60-4
This is because in such simple equations, x could only be found if all terms of x are isolated in one side of the equation before continuing other processes such as factorization,etc.
Answer:
Step-by-step explanation:
i AM PRETTY SURE ITS D
X = 3z - 22
z = 6
5x + 4y + 3z = 14
5 (3z - 22) + 4y + 3 (6) = 14
15z - 110 + 4y + 18 = 14
15 . 6 - 110 + 4y + 18 = 14
90 - 110 + 4y + 18 = 14
90 - 110 + 18 - 14 + 4y = 0
-16 + 4y = 0
4y = 16
y = 4
Answer:
Question 1: 148
Question 2: 4
Step-by-step explanation:
Question 1:
![12^2-23+(9*3)\\=144 - 23 + (27) \\=121+27\\=148](https://tex.z-dn.net/?f=12%5E2-23%2B%289%2A3%29%5C%5C%3D144%20-%2023%20%2B%20%2827%29%20%5C%5C%3D121%2B27%5C%5C%3D148)
Question 2:
