Answer:
Sum of those numbers are 50
Step-by-step explanation:
Let x represent a number that is twice as far away from 13 than 22.
The number can't be less than 13 but will be between 13 and 22 or slightly more than 22 otherwise it will be far away from both.
Thus;
|x - 13| = 2|x - 22|
It's in absolute form, so we will square both sides to get rid of the absolute brackets.
Thus;
(x - 13)² = 4(x - 22)²
x² - 26x + 169 = 4(x² - 44x + 484)
x² - 26x + 169 = 4x² - 176x + 1936
4x² - x² - 176x + 26x + 1936 - 169 = 0
3x² - 150 + 1767 = 0
Using quadratic formula, we have;
x = 19 or x = 31
Thus,the sum of the 2 numbers = 31 + 19 = 50
the complete question in the attached figure
the statements are
1) It makes less than plant B
2) It makes the same as plant A
3) It makes more than plant C
we know that
analyzing the graph
plant A
for x=40 y=100
for x=50 y=200
that means
the production in 10 days is 100 widgets
then
the production in 60 days will be 6*100----> 600 widgets
so
plant A production > plant fourth production
plant fourth production < plant A production
plant B
for x=40 y=0
for x=60 y=100
that means
the production in 20 days is 100 widgets
then
the production in 60 days will be 3*100----> 300 widgets
so
plant B production < plant fourth production
plant fourth production > plant B production
plant C
for x=20 y=0
for x=40 y=100
that means
the production in 20 days is 100 widgets
then
the production in 60 days will be 3*100----> 300 widgets
plant C production < plant fourth production
or
plant fourth production > plant C production
920
18 rounded is 20 as the second number is the ten
You put the answer as 2 already
