You're right, its B. I just took the test and got a 100%. Good luck on your test.
Answer:
Q1. 20x = 200. The value of x is 10
Q2. 7 - 3x = 1. The value of x is 2.
Step-by-step explanation:
In order to find an equation, you have to let the number be any variable, such as m or n or z. So I will let the number be <em>x variable</em>. Then the question says a number is multiplied by 20 is equals to 200 :
Let number = x,
Same for the next question. Given that a number multiplied by 3 :
Let number = x,
Then subtracted by 7 equals to 1 :
Answer:
Step-by-step explanation: x = 9
x = 3
Step by step solution :
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring x2-12x+27
The first term is, x2 its coefficient is 1 .
The middle term is, -12x its coefficient is -12 .
The last term, "the constant", is +27
Step-1 : Multiply the coefficient of the first term by the constant 1 • 27 = 27
Step-2 : Find two factors of 27 whose sum equals the coefficient of the middle term, which is -12 .
-27

-1

=
-12
That's it
