Answer:
(a).y=5z+x
this isn't a problem, just flip x to the other side
so x = 5z-y
(b). b=x/2a
cross multiply
x = b×2a
x= 2ab
c.8d=cx
divide both sides by c
8d/c=cx/c
x=8d/c
d.3px=12q
divide both sides by 3p
3px/3p=12q/3p
x=12p/3q
e. 4x=m/3-n
cross multiply
4x × 3 = m-n
12x = m-n
divide both sides by 12
12x/12=m-n/12
x = m-n/12
Answer:
13,260.22 mm²
Step-by-step explanation:
the area of the shaded region is the area of the larger circle minus the area of the smaller one
to find the area of the larger we will use half of 62 plus 41 as the radius:
Area (larger) = 3.14(72)²
= 16,277.76
Area (smaller) = 3.14(31)²
= 3,017.54
Area (shaded region) is 16277.76 - 3017.54 = 13,260.22 mm²
Answer:
The discriminant is 40
Step-by-step explanation:
First, rewrite the equation as 
so that the equation is in the form of 
. Thus, the discriminant is 
. This tells us that since the discriminant is greater than 0, then there are 2 real solutions.
1 yard equals three ft so 26 / 3
160 is the first because 1 inches 20 but it says 2 inches so at 40+40+40+40
and the 2nd part is yes he is correct because he converted the inches into feet so i think he is also correct
