Please help solve -2|5y-1|=-10

1 answer:

7 0

Alright, so we can start by dividing -2 from both sides, getting |5y-1|=20. Then, since 5y-1 is in an absolute value, 5y-1 is either 20 or -20.
In 5y-1=20, we can add one to both sides, getting 5y=21 and y=21/5. In
5y-1=-20, we can add one again, getting 5y=-19 and y=-19/5.

If you have any more equations, make sure to plug both numbers in to check, but otherwise y has two answers , which are -19/5 and 21/5.

A gum ball machine has 6 red gum balls, 3 green gum balls, and 5 blue gum balls. What is the probability that the next gum ball

lord [1]

Answer:

Step-by-step explanation:

P(red gum ball)= 6/14=3/7

6/14 can be simplified to 3/7 by dividing by 2. 6/2=3. 14/2=7.

P(red gum ball)=3/7

A grocery store has 120 bottles of spring

notka56 [123]

Question:

A grocery store has 120 bottles of spring water in stock. The store orders bottles of spring water in cases of 24. The store wants to order enough cases of spring water so it has more than 500 bottles in stock. Which inequality best models this situation?

A. 24x + 120 > 500

B. 24x - 120 > 500

C. 24x + 500 > 120

D. 24(x+120) > 500

Answer:

Option A. 24x + 120 > 500 is the inequality that best models this situation.

Step-by-step explanation:

The Number of bottles of spring water in the stock = 120

Each case of the spring water bottles contains 24 bottles

The store wants to order enough cases of spring water so that it has over 500 bottles in stock.

So there are already 120 bottles in stock .

The store will order

24x +120 > 500

where x is the number of spring water bottle cases

What is the constant term for -2a3b2+5ab5+7b4+8

stiv31 [10]

Hey there!

Constant terms are the terms where no variables are there (only the constant, i.e, the number). So, here the term 8 is the constant term because it doesn't have any variables.

Hope it helps ya!

7. If the longer leg of a right triangle is twice as long as the shorter leg, what is the ratio of

kicyunya [14]

Answer: The ratio is 2.39, which means that the larger acute angle is 2.39 times the smaller acute angle.

Step-by-step explanation:

I suppose that the "legs" of a triangle rectangle are the cathati.

if L is the length of the shorter leg, 2*L is the length of the longest leg.

Now you can remember the relation:

Tan(a) = (opposite cathetus)/(adjacent cathetus)

Then there is one acute angle calculated as:

Tan(θ) = (shorter leg)/(longer leg)

Tan(φ) = (longer leg)/(shorter leg)

And we want to find the ratio between the measure of the larger acute angle and the smaller acute angle.

Then we need to find θ and φ.

Tan(θ) = L/(2*L)

Tan(θ) = 1/2

θ = Atan(1/2) = 26.57°

Tan(φ) = (2*L)/L

Tan(φ) = 2

φ = Atan(2) = 63.43°

Then the ratio between the larger acute angle and the smaller acute angle is:

R = (63.43°)/(26.57°) = 2.39

This means that the larger acute angle is 2.39 times the smaller acute angle.
