Answer:
135 minutes
Step-by-step explanation:
Let
y -----> the number of pages to finish reading the book
x ----> the number of hours
we know that
The linear equation in slope intercept form is equal to
where
m is the unit rate or slope of the linear equation
b is the y-intercept or initial value
In this problem we have
<em>Xanthia</em>
----> the slope is negative because is a decreasing function
For y=0
substitute and solve for x
---> Xanthia's time to finish reading the book
<em>Molly</em>
----> the slope is negative because is a decreasing function
For y=0
--- Molly's time to finish reading the book
To find out how many more minutes than Xanthia would it take for Molly to finish reading the book, subtract Xanthia's time from Molly's time
Convert to minutes
Multiply by 60
600 and 60 I do not know what to do
The third term is 7
2(3) + 1 = 7
Hope this helps!
12.6-10.5=2.1(1.5 pounds) 2.1 divided by 3 = 0.7x2= 1.4 Therefore one pound of cheese is £1.40
In general, the sum of the measures of the interior angles of a quadrilateral is 360. This is true for every quadrilateral. This does not help here, because there are two angles (angles B and D) we know nothing about. We only know about opposite angles A and C.
In this case, you can use another theorem.
Opposite angles of an inscribed quadrilateral are supplementary.
m<A + m<C = 180
3x + 6 + x + 2 = 180
4x + 8 = 180
4x = 172
x = 43
m<A = 3x + 6 = 3(43) + 6 = 135
