Answer:
angle D equal to 3 X + 20 + 7 x minus 3 x
=90 degree equal to x minus 3 X + 20
7 X equal to 70 X equal to 10
So it would be $8.65/ 5lbs. And divide the top and the bottom by 5 and you get $1.73/ 1 lbs. I hope this helps!
Step-by-step explanation:
To divide by a fraction, multiply by its reciprocal.
1) (m² / 9) / (n² / m)
(m² / 9) × (m / n²)
m³ / (9n²)
2) (4 / y) / (2 / (yx))
(4 / y) × (yx / 2)
2x
3) (x² / y) / (1 / y)
(x² / y) × (y / 1)
x²
4) (3 / b) / (9 / a²)
(3 / b) × (a² / 9)
a² / (3b)
5) (x² / 16) / (16 / y²)
(x² / 16) × (y² / 16)
x²y² / 256
Answer:
-23, 
Step-by-step explanation:
We need slope intercept form but do not have the needed information. We will gather this information by using point slope form. The point-slope formula is
where we substitute a point (x,y) for
.
We have slope represented as m=6 and (3, -5). We input m and
.

We now simplify the parenthesis and solve for y to have slope intercept form.

The y-intercept is b of slope intercept form y=mx+b. Here b=-23.
