Answer:
it is the same on the other side
Step-by-step explanation:
1 step out the g where the other g is on the line it is on but other side
2 put x on same line with y but other side
Answer:
m=0
Step-by-step explanation:
How to solve your question 4 +5=5−4
Step 1: Rearrange Terms 4+5=5−4 4+5=−4+5
Step 2 : Subtract 5 from both sides 4+5=−4+5
-5 -5
Step 3 : Simplify 4m= -4m
Step 4: Add 4m to both sides of the equation 4m= -4m
+4 +4
Step 5: Simplify 8m=0
m=0
First, let us define our variables.
Let
x = age of the father
y = age of the son
z = age of the daughter
5 years ago..
(x – 5) = age of the father
(y – 5) = age of the son
(z – 5) = age of the daughter
After 18 years...
(x + 18) = age of the father
(y + 18) = age of the son
(z +18) = age of the daughter
From the first condition
y = z + 5 à
eqn 1
5 years ago
(x-5) = 23 + (y-5) + (z-5)
x –y –z = 18 à
eqn 2
after 18 years
(x+18) = 17*[(y +18 –z – 18)]
x – 17y + 17z = -18 à
eqn 3
solving the 3 equations simultaneously
x = 67
y = 27
z = 22
Answer:
B - it decreases
Step-by-step explanation:
Suppose m is 20
20 - 10 = 10
19 - 10 = 9
18 - 10 = 8
As m decreases, the expression decreases.
