Carrie found the difference 11/12 -- 2/3. she said * i found a common denominator 12,then subtracted the numerators to get 9/12* is carrie correct? Explain why she is or not correct.
Answer:
She isn't correct because after you find the common denominator, the numerator needs to be changed as well, so when she multiplied the denominator of 2/3 by 4 to get 12, she also had to multiply the 2 by 4, to get 8/12, and then subtracted, because otherwise, the new fraction isn't equivalent to the original fraction.

AB describes a line.
AB has a gradient of 3 and passes through the point (1, 15)
Find the equation of line AB,
Answer:
y = 3x + 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3 , then
y = 3x + c ← is the partial equation
To find c substitute (1, 15) into the partial equation
15 = 3 + c ⇒ c = 15 - 3 = 12
y = 3x + 12 ← equation of line AB

Factor the expression 28x -8
Answer:
4(7x-2)
Step-by-step explanation:
yeah so that's the answer your welcome
The factor of the polynomial expression 28x - 8 will be 4 and (7x - 2).
What is factorization?It is a technique for separating a polynomial into sorts that will be duplicated out. As of now, the polynomial's worth will be zero.
Polynomial math is the investigation of conceptual images, while rationale is the control of that multitude of thoughts.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The expression is given below.
⇒ 28x - 8
Factorize the expression, then we have
⇒ 28x - 8
⇒ 4·7x - 4·2
⇒ 4(7x - 2)
The element of the polynomial articulation 28x - 8 will be 4 and (7x - 2).

Answer:
x=121°
Step-by-step explanation:
the sum of angles in a triangle always equal 180°
that means that 22°+37°+x°=180°
so we solve the equation by isolating the variable
add 22 and 37 together
59°+x°=180°
subtract 59 from both sides
x=121°
that means that x is 121 degrees
