Answer:

There are 20 beads on the necklace.

Step-by-step explanation:

Given:

A beaded necklace is 2.5 feet long. Each bead is .25 inches wide & each pair of beads is separated by 1.25 inches of chain.

Now, to find the number of beads on the necklace.

The length of necklace = 2.5 feet.

So, we convert feet into inches by using conversion factor:

1 foot = 12 inches.

2.5 feet = 12 × 2.5 inches.

2.5 feet = 30 inches.

Thus, the length of necklace is 30 inches.

Let the number of beads be $x.$

The width of each bead = 0.25 inches.

The each pair of beads is separated by 1.25 inches.

Now, we put an equation to get the number of beads:

$(0.25+1.25)x=30$

$0.25x+1.25x=30$

$1.50x=30$

Dividing both sides by 1.50 we get:

$x=20.$

The number of beads = 20.

Therefore, there are 20 beads on the necklace.

Help please...

Vladimir [108]

Answer:

The first step is A. Subtraction

The second steep is D. Division

Step-by-step explanation:

The first step was done in other to remove the constant at one end of the equality that was with the variable, it was done in order to eradicate the constant and isolate the variable to make the equation easier to solve.

The second step was done in order to remove the coefficient of the variable so as the variable to be on it's own as x alone.

These two steps were just followed in order to find the value of the variable.

PLEASE HELP ME ASAP! I need to know the 3 equations to solve for the different types of points.

kiruha [24]

Answer:

f = 0

x > 2y

x ≤ 8

S ≥ 18

Step-by-step explanation:

Let 'f' represent the number of free throws.

Let 'x' represent the number of 2 - point baskets.

Let 'y' represent the number of 3 - point baskets.

Let S represent the Season high.

1) Ryan says he did not shoot any free throws.

⇒ f = 0

2) 2 - point baskets more than twice the number of 3 - point baskets.

⇒ x > 2y

3) Number of two points is less than or equal to 8.

⇒ x ≤ 8.

4) Last Season high, he had scored 18 points. Note that the problem says, Ryan equaled or bettered than last season high. That means he should got at least 18 points this season. So, the equation would be:

S ≥ 18

What is 420/15 simplified to

Ghella [55]

So,

In order to simplify a fraction, we have to factor both the numerator and the denominator.
$\frac{420}{15} --\ \textgreater \ \frac{2*2*3*5*7}{3*5}$

Cross out ones.
$\frac{2*2*7}{1}\ or\ 28$
