Answer:
B. 10 units
Step-by-step explanation:
The distance formula is useful.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((3-(-5))² +(-2-4)²) = √(64 +36) = √100
d = 10
The distance from L to M is 10 units.
Answer:
Mary is times heavier than her sister
Step-by-step explanation:
Mary's Weight = n
Sister's Weight = n - 15
To find how many times mary is heavier, we need to multiply "that many time" [let it be x] with sister's weight to get Mary's weight.
<u>e.g. </u>If someone weighs 100 and another person 50, 50 * 2 = 100, thus, 100 kg person is 2 times heaving. We do same for this:
(n - 15) * x = n
x = n/(n - 15)
Answer:
First, take x off of both sides making it: “5 -4 = 3 + 10”
Then subtract 3, making it “3(-7) = 10”
Then do 3 multiply 3 by -7, getting -21 = 10
that is how you would find out the equation is false
