Answer:
1/4(1 - 3x)
Step-by-step explanation:
Step 1: Write out expression
1/4 - 3/4x
Step 2: Factor out GCF
1/4(1 - 3x)
Speed is simply some number with some unit of speed at the end while velocity is speed with a direction.
The skydiver's velocity is 212 miles per hour downward.
The skydiver's speed is 212 miles per hour
Rate is closer to a constant pattern , example: I'm walking at a rate of 2 miles an hour.
Ratio is related to the proportion of two or more objects, example: The ratio for a perfect tang juice is 1 packet of tang dust thingy for 1.5 liters of water.
Hope it helps :)
Step 1: Line up the equations so that the variables are lined up vertically.
Step 2: Choose the easiest variable to eliminate and multiply both equations by different numbers so that the coefficients of that variable are the same.
Step 3: Subtract the two equations.
Step 4: Solve the one variable system.
Step 5: Put that value back into either equation to find the other equation.
Step 6: Reread the question and plug your answers back in to check.
Answer:
x=-4
Step-by-step explanation:
Distribute and expand everything in brackets.
2x+2*4x+2*-2+3x=x+3*x+3*-8+4x
2x+8x-4+3x=x+3x-24+4x
Solve like terms
13x-4=8x-24
Place like terms on same side.
13x-8x=-24+4
Solve for x
5x=-20
x=-4
