<u>Assuming that you want the product of the two factors given in each problem</u>:
⇒ we solve this problem by timing each unit of a factor to every unit
of the other factor
⇒then add each one of them who shares a common like-term
⇒to get the answer
<u>Let's solve:</u>
Hope that helps!
Step-by-step explanation:
Expression are problems with operations and terms, but no equal sign(s).
<u>Note: If a problem has an equal sign, it's an equation.</u>
*By eliminating the problems with equal signs, 12/4 =3 and 12 = 4 x 3 are incorrect.
12 + 4 - 3 and 12 - 4(3) are expressions, due to both problems not having an equal sign.
Sorry I don’t know the answer but I need to get answers for this quiz or I’ll fail
I hope you have a bless day
Answer:
x=1,y=3
correct answer is (1,3)
Step-by-step explanation:
We can quickly eliminate y by subtracting one equation from the other
(-2x+y=1)-(-4x+y=-1)
2x=2
x=1
plug x=1 into equation 1
-2(1)+y=1
y=1+2=3
Divide 12 on both sides
ds/w=cd/12
now multiply ds on both sides
w=cd/12ds
