Answer:
x-9 = 16
Step-by-step explanation:
Given: Samantha donated 9 t-shirts to charity and left with 16 t-shirt.
Let x be the total number of t-shirt Samantha had originally .
As 9 t-shirt been donated to charity out of her total t-shirt
∴ equation will be
Now, she is left with 16 t-shirt
so,
∴ The equation to find x or total number t-shirt samatha had originally is
Add up all the rainfall amounts and divide by 11
Answer:
There will be 135 squares in total. Changing the order of the factors wont change the result.
Step-by-step explanation:
(i am assuming that sqaures = sqaure pieces)
Each section has 3 rows of 15 square pieces, therefore each section has 3*15 = 45 sqaure pieces. Thus, the complete guilt will have 45*3 = 135 square pieces. Since all we do were multiplications, changing the order of the factors wont change the value of the product.
1) (y^2-2y+1)/(2y-3)
2y-3=0
Solving for y:
2y-3+3=0+3
2y=3
2y/2=3/2
y=3/2
2) y(y+5)/(4y+1)
4y+1=0
Solving for y:
4y+1-1=0-1
4y=-1
4y/4=-1/4
y=-1/4
3) (5y^2-6y+1)/[-5(y-1)]
-5(y-1)=0
Solving for y:
-5(y-1)/(-5)=0/(-5)
y-1=0
y-1+1=0+1
y=1
4) (y^2-y-6)/[-2(y+7)]
-2(y+7)=0
-2(y+7)/(-2)=0/(-2)
y+7=0
y+7-7=0-7
y=-7
Pairs
-7 → (y^2-y+6)/[-2(y+7)]
3/2 → (y^2-2y+1)/(2y-3)
1 → (5y^2-6y+1)/[(-5(y-1)]
-1/4 → y(y+5)/(4y+1)
Answer:
35 hours
Step-by-step explanation:
She would need to work for 35 hours.
She earned $250.25 total the first two weeks, so divide that by the new rate per hour, $7.15, to get the 35 hours.
