cross multiply. 28 times 2 and 1 times x. set them equal to each other and solve for x to get 56.
Answer:
IS A FACTOR
Step-by-step explanation:
1X120=120
2X60=120
3X40=120
4X30=120
FACTORS 1,2,3,4 30,40,60,120
1) plug in 1 for x to get the following:
1^2 + 2(1)
1^2 = 1
2 * 1 = 2
1 + 2 = 3
the answer is 3.
2) for estimating, your teacher may have another method but here's how i was taught:
determine whether to round up or down to a whole number:
7.9 rounds up to 8 and 0.67 rounds up to 1, and 8 * 1 is 8, so i would estimate the answer to be 8.
(i can't do the remaining two sorry!!)
Answer:
slope =-1/14
Step-by-step explanation:
slope =(y1-y2)/(x1-x2)
slope=(1-2)/(-3--17)
slope=-1/14
52000 times .12 equals 6240
