Answer:
12
Step-by-step explanation:
if you multiply everything by 5, then you can get rid of the fraction and the equation would now look like this:
x - 40 = 20
and now you can answer this simply
x - 40 = 20
+40 +40
x = 60
and since you multiplied 5 beforehand, now you have to divide by 5 to get the real answer
60 ÷ 5 = 12
therefore, x = 12
X = 4y
3x - y = 70
substitute the x in the second equation with the other half of the first equation.
3(4y) - y = 70
12y - y = 70
11y = 70
y = 6.36 repeating, or 6 4/11
now use this to solve first equation
x = 4 (6 4/11)
x = 25.45 repeating
done
Answer:
C on the IA#3 I am in GCA to LOL
Step-by-step explanation:
Answer:
A: x+5
B: 4x-1
Step-by-step explanation:
4x^2+19x-5
(4x ) ( x )
We know that 1 will be positive and 1 will be negative.
Our choices for the numbers are 5 and 1
4*5 -1 = 19
(4 x - 1) (x + 5)
