Answer:
10.25 gallons
Step-by-step explanation:
432 miles / 6 gallons=72 miles to gallon
738 miles / 72 miles per gallon=10.25 gallons

Step-by-step explanation:
First we need to get the slope of the perpendicular line
The slope of a perpendicular line is equal to the negative inverse of the slope of the given line
y
=

Now that we have the slope, we need to find the y-intercept.
To find the y-intercept, we need to plug-in values of
x
and
y
that the line passes through

Answer:
£2.38
Step-by-step explanation:
2.5 cost £1.40
4.25 cost £ x
so x=(4.25*1.40)/2.5=5.95/2.5=£2.38
Answer:
y=3x-2
Step-by-step explanation:
y=mx+b where m=slope and b=y-intercept
y=3x-2
A divide by sin A = b divide by sin B
1. 27 divide by sin 68=22 divide by sin x
Sin x=sin 68 times 22 divide by 27
Sinx=0.65696
X=71.7 degrees
