Since the coefficient of x is 3, you’d need to divide each number by three. So, you’d get -1
Answer:
105cm
Step-by-step explanation:
Call the rat's height r, the cat's height c and the table height t.
The left part says that
(t + c) - (0 + r) = 120 = t + c - r
c - r = 120 - t
Right part says that (t + r) - (0 + c) = 90 = t + r - c
c - r = t - 90
120 - t = t - 90
2t = 210
t = 105
Always use the inverse (opposite) operation. Ex. is 2x+4=10.
First subtract 4, and then divide by 2.
actually reverse of order of operations to solve.
Round to the nearest thousand.
Look at the number in the place value to the right (hundreds). It is a 1. Because 1 is less than 5, round down
4000 is your answer
hope this helps
