What is the ratio of x to y?

Answers

Answer 1

Answer: 2/3 = x/(3x + y)

2*(3x + y) = 3*x

2*3x + 2*y = 3x

6x + 2y = 3x

6x - 3x = - 2y

3x = -2y

x/y = -2/3

x : y = -2/3.

Craig drank two 5-cup bottles of water in one day how many fluid onces is that

Answers

There are 8 fl oz in 1 cup. First we need to figure out how many cups he drank (multiply 5 by 2). Then multiply how many cups he drank (10) by how many fl oz are in a cup (8). There are 80 fluid ounces in 10 cups of water :)

The answer would be 80 because there are 8 oz. in a cup, so you would do 8x5 for the first bottle which is 40. You would then double 40 to get both of the water bottles. 40x2= 80.

The perimeter of an isosceles triangle is 15.6m. Find the lengths of its sides, if:The base is 3m smaller than a leg.

Answers

Answer:

so length of sides is 6 .2 m ( other side will also be 6.2 m)

base = 3.2 cm

Step-by-step explanation:

solution

let the length of sides of isosceles triangle is = x

as two sides of of isosceles triangle are equal

let the length of the side be x

so length of side = x

base = x -3 ( as it is 3 m smaller in length )

according to formula of perimeter of isosceles triangle

perimeter = 2 (side) + Base

adding the values

15.6 = 2 (x) + x-3

15.6 = 2x +x -3

15.6 = 3x-3

15.6 = 3( x-1) taking 3 common

dividing both sides by 3

15.6/3 = 3(x-1)/3

5.2 =x-1

or x -1 = 5.2

adding 1 from both sides

x-1 +1 = 5.2 +1

x = 6.2

so length of sides is 6 .2 m ( other side will also be 6.2 m)

base = x-3 = 6.2-3 = 3.2 m

Answer:

6 .2 m ,6.3 m, 3.2 m
