Answer: 7/8
Step-by-step explanation:
You can change all the fractions to have equivalent denominators.
The Least Common Denominator of 1 1/4 and 3/8 is 8. Now we can change the fractions.
1 1/4 = 1 2/8 = 10/8.
3/8 = 3/8.
Now we can subtract. Subtract the numerators of the first fraction from the numerators of the second fraction, and the denominators oft he first fraction to the denominators of the second fraction.
10/8 - 3/8 = 7/8.
Therefore, 1 1/4 - 3/8 = 7/8; the fourth answer.
Answer:
There is another method for solving systems of equations: the addition/subtraction method. ... Multiply one or both equations by an integer so that one term has equal and opposite coefficients in the two equations. Add the equations to produce a single equation with one variable. Solve for the variable.
Answer: (b)
Step-by-step explanation:
the y-intercept is 4.
the slope of the line is -1x, or -x.
on a calculator, that would be 6
Answer:
x= -2 x=-2
Step-by-step explanation:
move over the leading coefficient and you get
3x²+12x+12
the pull out a 3 because that's your gcf and 3 cannot equal zero so you can just do without id and you get
x²+4x+4
and when you factor that you get
(x+2)(x+2)
and when you set those equal to zero you get x= -2 and x= -2
