Answer:
See below.
Step-by-step explanation:
a)
105/3 = 35
35/5 = 7
7/7 = 1
429/3 = 143
143/11 = 13
13/13 = 1
105 = 3 * 5 * 7
429 = 3 * 11 * 13
Not co-prime
For the other parts of the problem, do the same I did above. Find the prime factorizations of both numbers, and see if they have any prime factors in common.
Check the picture below, so the distance of the house from the other side is that blue gap.
so, there are 12 inches in 1 foot, so let's just convert all those feet to inches and subtract them.
Answer:
C)
Step-by-step explanation:
Answer:
y = -3.5x - 12
Step-by-step explanation:
Find the slope with rise over run: (y2 - y1) / (x2 - x1)
Plug in the points:
(9 + 5) / (-6 + 2)
14/-4
= -3.5
Then, plug this and a point into the equation y = mx + b to find b:
y = mx + b
9 = -3.5(-6) + b
9 = 21 + b
-12 = b
Then, plug this and the slope into the equation again:
y = mx + b
y = -3.5x - 12 will be the equation
64. 87.5% in fractions is 7/8. We divide 56 by 7/8, and get to 64.
56 ÷ 7/8= 56 x 8/7= 448/7, which is reduced into 64.
