Both grab 1 sheet of stickers and 13 singles
p + 2 = 5 ==> p = 3
3p + 2 = p + 3 ==> 2p = 2 ==> p = 1
3k + 5 = 2k + 2 ==> k = -3 (niemożliwe; lewa strona wagi ma większą wagę)
2w + 10 = 4w + 7 ==> 2w = 3 ==> w = 3/2
d + 9 = 3d + 2 ==> 2d = 7 ==> d = 7/2
W drugim zadanie każda litera reprezentuje wagę jednego z obiektów. Na przykład 3k + 4 reprezentuje całkowitą wagę 3 kół i 4 ciężarów, każdy o wadze 1 kg.
Trzecie zadanie to tylko połączenie dwóch pozostałych.
Answer:
The slope of the model is
.
The value of the slope indicates that the average cost of a hair cut is increased by 2 US dollars each year.
Step-by-step explanation:
We have to notice that given function is a linear function, that is, a first order polynomial, whose standard form is described below:

Where:
- Slope, dimensionless.
- Independent variable, dimensionless.
- Dependent variable, dimensionless.
- y-Intercept, dimensionless.
In this case, we use the linear function
, where
is the time after 2000, measured in years, and
is the average cost of a hair cut. The slope of the model is
.
The value of the slope indicates that the average cost of a hair cut is increased by 2 US dollars each year.
Answer:
The length of the rectangle is 11 inch and its width is 8 inch.
Step-by-step explanation:
Given:
Rectangle
and rectangle
.
Let the width of the rectangle be 'x' inch.
Its length = '(x+3)' inch
Area of the rectangle = 
⇒
= 
Now for rectangle
its width is decreased by 1 inch and length is doubled,the area
will increased by 66 sq-inch.
So,
According to the question.
⇒ Area of rectangle
with width '(x-1)' and length '2(x+3)'='(2x+6)' .
⇒ 
Plugging the values of
in terms of
.
⇒ 
Plugging
=
into the equation.
⇒
⇒ 
⇒ 
⇒ 
Now using quadratic formula we can find the value of 'x'.
Quadratic formula, (x)=
x= -9 and x= 8
Discarding the negative value.
Our width = 'x' = 8 inches.
So the length of the rectangle = 11 inches and width of the rectangle = 8 inches.
So she has

cups of yogurt for making fruit parfaits, and each parfait requires

cup of yogurt. This would imply that we would have to divide the first fraction by the second fraction to find out how many parfaits she can make.
Skip, switch, flip (I believe that's how the statement goes?) When you are dividing a fraction, you skip the first fraction, switch the division sign into a multiplication sign, and flip the second fraction so the denominator is the numerator, and the numerator is the denominator. That would make it :

×

: And 14 × 6 is 84, and 6 times 2 is 12. That would mean that we divide

.
84 divided by 12 is 7. She can make
7 parfaits.
