Find the measure of angle x in the figure below: A) 35 B) 47 C) 51 D) 62

sasho [114]

Answer:

The value of y = 62°

and x = 50°

Step-by-step explanation:

=> 57° + y + 61° = 180°

=> 118° + y = 180°

=> y = 180° - 118

=> y = 62°

Now ,

x° + y° + 67° = 180° { sum of angles of a triangle is 180° }

=> x° + 62° + 68° = 180°

=> x + 130° = 180°

=> x = 180° - 130°

=> x = 50°

How many gallons of 30% alcohol solution and how many of 60% alcohol solution must be mixed to produce 18 gallons of 50% solutio

allochka39001 [22]

Answer:

x = 6 gallons (of 30% alcohol)

y = 12 gallons (of 60% alcohol)

Step-by-step explanation:

Let

x = liters of 30% alcohol

y = liters of 60% alcohol

There are two unknowns, we need two equations

x + y = 18. (1)

0.30x + 0.60y = 0.50(x+y) (2)

From (1)

x + y = 18

y = 18-x

Substitute the value of y into (2) and solve for x:

0.30x + 0.60y = 0.50(x+y)

0.30x + 0.60(18-x) = 0.50(x+18-x)

0.30x + 10.8 - 0.60x = 0.50(18)

10.8 - 0.30x = 9

-0.30x = -1.8

Divide both sides by -0.30

x = 6 gallons (of 30% alcohol)

Substitute x=6 into (1) and solve for y:

x + y = 18

6 + y = 18

y = 12 gallons (of 60% alcohol)
