It is a simple problem where 120 centimeters need to be increased by 24%. The increased length can be found by: 120 * (24/100) = 12 * (24/10) = 288/10 = 28.8 centimeters Then the total length of increase = 28.8 cm Then the increased length = (120 + 28.8) cm = 148.8 cm So the length becomes 148.8 cm after it is increased by 24%.

Which ordered pair is the solution to the system of equations? A. (1, 7) B. (4, 9) C. (7, 19) D. (8, 21)
Answers
I could just give you the answer but you should know how so you don't need my help :)
Solve by substitution.
Step 1: Set the first equation to y by isolating the y term.
2x-y=-5 2x+5=y (see how that worked? I flipped the signs of the numbers and moved them)
Step 2: Substitute the new equation for y in the second equation.
x+3y=22 -> x+3(2x+5)=22 (now lets simplify) 7x+15=22 (I distributed and added like terms) (now we can isolate that pesky x term) 7x=7 (now its trickier than just flipping the sign, now i have to divide x by 7 since it is multiplied by 7) x=1
Step 3; Substitute the new x answer into the original first equation
2x-y=-5 -> 2(1)-y=-5 (Lets isolate now since we already know that 2x1 is 2.) -y=-7 (lets cancel out those signs to finish the isolation) y=7
So your answer is 1,7
Which is bigger 0.125 or 0.15
Answers
0.15 because if you put it in a T-chart and add a place holder 0.15 turns into 0.150 so, 0.150 is more than 0.125

I believe your answer would be 3/4.
2/5+1/4+1/10=? find the lowest commune denominator 20 5×4=20 4×5=20 10×2=20 2×4=8 1×5=5 1×2=2 8+5+2=15 15/20 redoes to lowest terms 3/4
