Answer:
v = 25.6
Step-by-step explanation:
1. Multiply both sides of the equation by 4.
(6.4)(4) = 25.6
The anser for 6 is 25/92
The answer for 7 is 1 1/2
Answer:
D.
Step-by-step explanation:
It's a right triangle so

x = 41
Answer:
-8/3
Step-by-step explanation:
First find the slope of the line
3x+y = 1
Solve for y
y = -3x+1
This is in slope intercept form
y = mx+b where m is the slope
The slope is -3
The slopes of perpendicular lines multiply to -1
m* -3 = -1
m = 1/3
The line perpendicular has a slope of 1 / (3) = 1/3
The sum is -3 + 1/3
-9/2 + 1/3 = -8/3

First, solve the parentheses:

Next, the exponential terms

Solve the multiplication:

Add and subtract:
