Answer:
0.68
Step-by-step explanation:
$17 out of $25 comes to 17/25, or 0.68. This is the desired decimal equivalent.
Let's solve this:
I'm going to assume that -7/8x and those similar are (-7/8) times x and so on.
from first glance, the fourth equation looks like a failed attempt at a modifier of the first equation.
Start: First equation:
-(7/8)x - (3/4) = 20
multiply both sides of the equation by -1 to make it the 2nd equation:
(7/8)x + (3/4) = -(20)
or to get the third equation from the first, distribute the numerator in -(7/8)x outside the parentheses (remember: top/bottom = top times 1 over bottom) :
- 7(1/8)x - (3/4) - 20
equation 4 is weird (lets try to derive the first one from it):
-(7/8)(-8/7)x - (3/4) = 20(-8/7)
divide to 'get rid' of the (-8/7)
-(7/8)x - (3/4)/(-8/7) = 20
first and third terms are right but the second isn't; therefore, the 4th equation is the different one
Answer:
B
Step-by-step explanation:
A right angle
Answer:
y = 2x - 6
Step-by-step explanation:
The slopes of parallel lines have the same slope, so the other line must also have a slope of 2.
First, we know that an equation in point-slope form is y-y1 = m(x-x1). We can plug in the values here (5, 4) into the equation:
y - 4 = 2(x-5)
Simplify:
y - 4 = 2x - 10
Therefore, the equation is:
y = 2x - 6
