find the value of x and y

Answers

Answer:

5 = y

6.5 = x

Step-by-step explanation:

Since all the angles are the same, you can determine that all the sides are the same lengths.

8 = y + 3

8 - 3 = y

5 = y

8 = 2x - 5

8 + 5 = 2x

13 = 2x

13/2 = x

6.5 = x

Answer:

2x - 5 = 8

+5 +5

2x = 13

Divide by 2 on both sides:

X = 6.5

Y + 3 = 8

-3 -3

Y = 5

They must equal 8 since all sides are the same.

Answer:

[tex]\sqrt{y}[/tex] ÷ xz²

Step-by-step explanation:

multiply the exponent of 'x' by -2 to get -1

multiply the exponent of 'y' by -2 to get 1/2

multiply the exponent of 'z' by -2 to get -2

= (x^-1)(y^1/2)(z^-2)

= 1/x · [tex]\sqrt{y}[/tex] · 1/z²

= [tex]\sqrt{y}[/tex] / xz²

if there are 300 calories in 100 g of a certain food, how many calories are there in a 30 g portion of food

Answers

Answer:

90 calories

Step-by-step explanation:

Calories : quantity of food

there are 300 calories in 100 g of a certain food

300 calories : 100 g food

how many calories are there in a 30 g portion of food

Let x = number of calories

x calories : 30 g food

Equate both ratios

300 calories : 100 g food = x calories : 30 g food

300/100 = x/30

300 * 30 = 100 * x

9000 = 100x

x = 9000/100

x = 90

x = number of calories = 90 calories
