Cross multiply.
3.3*100 is 330
330/15 is 22
The bill was $22 before the tip

Hanna's dad is designing a new rectangular garden for his backyard. He has a 20ft fence to put around the garden. He wants the l

vovangra [49]

Answer:

3 3/4 feet

Step-by-step explanation:

Given

Perimeter of the garden = 20ft

If he wants the length of the garden to be 2 1/2 longer than its width, then;

L = 2 1/2 + W

L is the length

W is the width

Perimeter of the garden = 2(L+W)

P20 = 2(5/2 + W+W)

20 = 5 + 2W+2W

20 - 5 = 4W

15 = 4W

W = 15/4

W = 3 3/4 ft

Hence the width of the garden is 3 3/4 feet

A metal bar weighs 8.15 ounces. 93% of the bar is silver. How many ounces of silver are in the bar

Ksivusya [100]

7.5795 ounces.
Multiply the weight of the bar by the percentage of silver of the bar. Make sure to turn the percentage into decimal.
8.15-93/100-7.5795.
Round to two decimals if necessary, (which is 7.58).

Good luck.

Solve for y. 2/(y+3)= 3/(3y+9)

AfilCa [17]

Answer:

y= -3

Step-by-step explanation:

Multiply all terms by the same value to eliminate fraction denominators:

2/y +3 = 3/3y + 9

(3y+9) (y+3) (2/y+3) = (3y +9) (3/3y+9)

Simplify:

6 + 1 8 = 3 + 9

Subtract 18 from both sides of the equation:

6y +18 =3y +9

6y+18 -18 =3y +9 -18

Simplify Again:

6y +3y-9

Subtract 3y from both sides of the equation:

6y =3y -9

6y-3y = 3y -9 -3y

Answer:

y= -3
