3x + y = -8
<u>-3x </u> <u> -3x</u>
y = -3x - 8
Choose values for x, then input that value into the equation to solve for y:
FYI: Do you see the pattern?
<em>Each time you add 1 to the x-value, you subtract 3 from the y-value.</em>
Answer:
2.5
and
y=2.5x
Step-by-step explanation:
Answer:
2 7/12
Step-by-step explanation:
−512−−93=?
Since the the second fraction is negative and you are subtracting, remove the negative sign and switch the operation to addition.
The equivalent equation is
−512+93=?
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(-5/12, 9/3) = 12
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(−5/12×1/1)+(9/3×4/4)=?
Complete the multiplication and the equation becomes
−5/12+36/12=?
The two fractions now have like denominators so you can subtract the numerators.
Then:
−5+36/12=31/12
This fraction cannot be reduced.
The fraction
31/12
is the same as
31÷12
Convert to a mixed number using
long division for 31 ÷ 12 = 2R7, so
31/12=2 7/12
Therefore:
−5/12−−9/3=2 7/12
7/16 * 4/3 * 1/2 = 28/96 = 0.29
You have to subtract 4.35 from 15.60 to see for all the children
3x+4.35 = 15.60
