Answer:

6

Step-by-step explanation:

5(3g + 2)/2 = 50              Multiply both sides by 2

5(3g + 2)  = 50*2 = 100   Remove the brackets

15g + 10 = 100                  Subtract 10     ***

15g+10-10 = 100 - 10         Collect like terms.

15g = 90                            Divide by 15   ***

15g/15 = 90/15

g = 6

I don't know how to cut this down so that it requires only 2 steps.  I guess that the two steps marked with *** are the 2 I would choose.

Answer:

g=6

Step-by-step explanation:

We can start by multiplying both sides by 2

5(3g+2)=100

Now we can distribute the 5 by using the distributive property

15g+10=100

Then we subtract 10 from both sides

15g=90

Divide both sides by 15

g=6

a vending machine sells chips at $0.40 and candy at $0.50. Last month, the vending machine yielded $152.80 with a sale of 328 items. how many packages of chips were purchased last month

Answers

112 bags of chips

The solution to the system of equations gives 112 chips and 216 candy.
The equations to solve are 

x + y = 328
.40x + .50 y = 152.80

(x = the number of chips and y = the number of candy)
x = 40 cents bags, y = 50 cent bags

x + y = 328...x = 328 - y
0.40x + 0.50y = 152.80

0.40(328 - y) + 0.50y = 152.80
131.20 - 0.40y + 0.50y = 152.80
-0.40y + 0.50y = 152.80 - 131.20
0.10y = 21.60
y = 21.60/0.10
y = 216 <=== total 50 cents bags sold

x + y = 328
x + 216 = 328
x = 328 - 216
x = 112 <=== total 40 cents bags sold

In a 30-60-90 triangle the long leg is half the hypotenuse
Always
Sometime
Never

Answers

Answer:

Never.

Step-by-step explanation:

Definition:

In a 30-60-90 triangles:

  • The length of a hypotenuse sides is twice the length of the shorter leg
  • The length of the Longer side is √(3) times the shorter leg.

As per the statement:

In a 30-60-90 triangle the long leg is half the hypotenuse.

since,

\text{Shorter leg} = (1)/(√(3)) \cdot \text{Length of longer side}

By definition;

length of a hypotenuse sides is twice the length of the shorter leg

⇒\text{length of hypotenuse} = 2 \cdot (1)/(√(3)) \cdot \text{Length of longer side}

⇒\text{length of hypotenuse} =(2)/(√(3)) \cdot \text{Length of longer side}

⇒\text{length of longer side} =(√(3))/(2) \cdot \text{Length of Hypotenuse side}

Therefore. the given statement "In a 30-60-90 triangle the long leg is half the hypotenuse." is Never.
I wanted to say Sometime
But I believe the answer is Never
