2/3 of the list = 12

2/3x = 12
x = 12 / (2/3)
x = 12 * 3/2
x = 36/2
x = 18 <=== there are 18 words on the list

Jill says he did it wrong. He should have multiplied the bottom first (3 x 5) and then multiplied by the height. Explain to Jill
inna [77]

Answer:

Step-by-step explanation:

Jack's method is equivalent because of the "law of commutative property", which means that multiplication problems have the same result no matter the order.

a car decreased in value from $980 to $720 in one year what was the per cent of decrease to the nearest whole per cent ?
kolezko [41]

The decrease was 27%.

Step-by-step explanation:

Old value = $980

New value = $720

Decrease = Old value - New value

Decrease=980-720=\$260

Percent decrease = \frac{Decreased/ amount}{Old value}*100

Percent\ decrease=\frac{260}{980}*100\\Percent\ decrease=0.265*100\\Percent\ decrease= 26.5\%

Rounding off to near whole percent

Percent decrease = 27%

The decrease was 27%.

How do i solve for x and what is the answer
kiruha [24]

Answer:

(4+8)(4) = (x) 3

Step-by-step explanation:

The picture shows two secants intersecting at a point outside the circle.  A beautiful pattern for this is:  along each secant, the product (multiply) the <em>entire</em> secant by the <em>outside</em> part is the same.

(entire secant)(outside part) = (entire secant)(ouside part)

(4+8)(4) = (x)(3)

The equation of three other functions are given which function or functions have a slope equal to the slope of Function 1
ratelena [41]

Answer:

See Explanation

Step-by-step explanation:

Required

Function(s) with the same slope as function 1

The question is incomplete as function 1 and the three additional functions are not given.

However, I will provide a general explanation.

A slope is represented as:

y = mx + b

Where

m \to slope

So, considering the following equations

y = 2x + 3

y = \frac{3x}{2} + 9

y = 2x - 5

y = -2x + 3

The following equations have the same slope

y = 2x + 3 and y = 2x - 5

Because: y = mx + b implies that:

m = 2 for y = 2x + 3 and y = 2x - 5

Which algebraic expression is a monomial term?
ICE Princess25 [194]

Answer:

  (c)  45x³y

Step-by-step explanation:

Terms of a polynomial expression are separated by + or - signs. If there is only one term, there is no need to separate terms with such signs.

<h3>One term</h3>

The one-term expression is ...

  45x³y

__

<em>Additional comments</em>

If the coefficient of a one-term expression is negative, there will be a leading minus sign. There won't be another term on the other side of that sign.

The given expressions appear to suffer from poor editing. Ordinarily, exponents are rendered using a superscript font, as the 3 is in the first expression. However, the second term of that expression is 1x2, which we understand to be 1x². If the 2 were intended as a multiplier, rather than an exponent, we would expect it to be combined with the coefficient 1 in that term to give (xy)³ -2x.

It is this assumption that leads us to write 45x3y as 45x³y. If that is not the intention of the given expression, it could be simplified to 135xy.

Ordinarily, if an exponent is not rendered in superscript font, we expect it to be identified by the caret (^) operator, as in 45x^3y.
