Answer:
{7x^2+168x+840}/{x+12}
Step-by-step explanation:
Independent because the ratio of the second cube is the same (1:6), and it isn't affected by the result of the first cube
Answer:
Step-by-step explanation:
j because of the alzemiers algorithim
90
15x3=45
45x2=90
so kristen baked 90 cupcakes in 2 hours
Make x the subject
2x = -3y + 1
5x = -2y -3
now times the answers to get the lcd
(2x = -3y + 1) x 5
10x = -15y + 5
(5x = -2y -3) 2
10x = -4y -6
now that they are equal to the same number:
-15y + 5 = -4y -6
-15y + 4y = -6 -5
-11y = -11
y = 1
now to find x we substitute y
2x = -3y + 1
2x = -3(1) + 1
2x = -3 + 1
2x = -2
x = -1
