Answer:
is it subtraction or addition?
Step-by-step explanation:
Answer:
we are given with two terms: 20 k and 50. In this case, we are asked in the problem to factor the two terms forming the expression. The common factor of 20k and 50 is 10 because the two terms are divisible by it. The answer hence is 10*(2k +5)
Step-by-step explanation:
5x + 2y = 7....multiply by -3
-2x + 6y = 9
----------------
-15x - 6y = -21 (result of multiplying by -3)
-2x + 6y = 9
---------------add
-17x = - 12
x = 12/17 or 0.7
5x + 2y = 7
5(12/17) + 2y = 7
60/17 + 2y = 7
2y = 7 - 60/17
2y = 119/17 - 60/17
2y = 59/17
y = 59/17 * 1/2
y = 59/34 or 1.7 when rounded <====
Answer:
x=6.625
Step-by-step explanation:
I did 17x -23+7x+2 then I simplified it to 24x-21 =180 then I cancelled out 21 then I got 24x=159 then cancelled out 24 then divided 159 by 24 and then got 6.625
