5/16 = 25/80
3/8 = 30/80
2/5 = 32/80
Because 25/80<30/80<32/80, the washer with the size of 5/16 inch is the smallest~
W+d=869
w=d-81
plug in
(d-81)+d=869
2d-81=869
+81 both sides
2d=950
÷2 both sides
d=475
dryer cost $475
let's check w=475-81
w=394
475+394=869
869=869
the solution is true :)
Answer:
A) x = 12
Step-by-step explanation:
if its a right angle? then the angle in total is 90 degrees,
subtract the 35 from 90 to get 55 degrees,
4x + 7 = 55 solve this
4x = 48
x = 12
Probably b. flyer
Of course, it's tough to tell without the selection.
