Given x : y: z = 5:1:3 and z - y = 28. find the value of x + y​
Vera_Pavlovna [14]

Answer:

x + y = 84

Step-by-step explanation:

Given

x : y : z = 5 : 1 : 3, then

\frac{x}{y} = 5 ( multiply both sides by y )

x = 5y ←

and \frac{y}{z} = \frac{1}{3} ( cross- multiply )

3y = z

Substitute z = 3y into z - y = 28

3y - y = 28

2y = 28 ( divide both sides by 2 )

y = 14 ← ←

Substitute y = 14 into x = 5y

x = 5 × 14 = 70 ← ←

Substitute y = 14 into z - y = 28

z - 14 = 28 ( add 14 to both sides )

z = 42 ← ←

Thus x = 70, y = 14 and z = 42

Hence x + y = 70 + 14 = 84

a triangle has two sides of lengths 5 and 12. What value could the length of the third side be? Check all that apply. Apex... PL
ASHA 777 [7]

Step-by-step explanation:

The length of any side of a triangle must be less than the sum of the other 2 sides of the triangle.

Let x be the length of the 3rd side. Then we have constraints 5 + 12 > x and 5 + x > 12.

This gives 17 > x and x > 7, hence the answer is 7 < Length of the 3rd side < 17.
