How many times does 2 go into 7. find that out and you will know
Answer:
rearrange to get x < -4
Step-by-step explanation:
First we define variables:
x: amount of money Jack has
y: amount of money Eric has
We write the system of equations:
x = y + 80
x - 30 = 2y
Solving the system we have:
x = $130
y = $ 50
Therefore, the amount of money they had at the beginning is:
130 + 50 = $ 180
Answer:
the boys had $ 180 altogether at the beginning
Given that,in triangleABC,
mmmTo find:mSolution: We know that angle sum property of a triangle =180 degrees
=>m=>2x+12+x+14+3x+4=180
=>2x+x+3x+12+14+4=180
=>6x+30=180
=>6x=180-30
=>6x=150
=>x=150/6
=>x=25
Therefore mHope this helps you....
