$350= $130+$20x, x= amount of weeks
$350-$130=$220 $20*11=220
Answer: 11 weeks
94=y/4-18
first you would +18 on each side with a result of 112=y/4 then you would x4 on each side with an end result of 448=y
y=448
.8 (88%)+.2x=90%
70.4%+.2x=90%
subtract 70.4% from 90% to get 19.6%
make the .2x into 2 and the 19.6 into 196
divide 196 by 2 to come up with the answer of 98%.
you will need a 98% to have a 90% for the final grade
Hello!
To find the side length of a square with the diagonal you use the equation
a is side length
d is diagonal length
Put in the values you know
Divide
Multiply
a = 22.6
All the sides are 22.6 feet
Add all the sides
22.6 + 22.6 + 22.6 + 22.6 = 90.4
The answer is 90.4
