C. Aunt Beth bought 1 3/8 yards of blue ribbon
and 1/2 yards of green ribbon. How much
more blue ribbon was bought?
7/8 yards more blue ribbon was bought
How much more blue ribbon was bought?
The given parameters are
Blue ribbon = 1 3/8 yards
Green ribbon = 1/2 yards
The amount of excess ribbon that is blue is
Excess = Blue ribbon - Green ribbon
So, we have
Excess = 1 3/8 yards - 1/2 yards
Evaluate the difference
Excess = 7/8 yards
Hence, 7/8 yards more blue ribbon was bought

Jake is traveling 13 mph in his boat. After 4 hours, how far will he have traveled?
Answer:
Step-by-step explanation: First create an equation. So it'll be...
M(h)=13h (M= Miles & H = Hours)
Plug in the 4 where the h is at so...
M(4) = 13(4)
So then multiply 13 by 4 and you get 52.
So the answer is..
At 4 hours Jake would have traveled 52 miles.
or the equation is
M(4) = 52

Owen is a songwriter who collects royalties on his songs whenever they are played in a commercial or a movie. Owen will earn $50 every time one of his songs is played in a commercial and he will earn $140 every time one of his songs is played in a movie. Owen's songs were played on 4 more commercials than movies, and his total earnings on the royalties from all commercials and movies was $770. Determine the number of commercials and the number of movies on which Owen's songs were played.
Answer:
His songs were played 4 times in a commercial, and 3 times in a movie.
Step-by-step explanation:
Let x represent the number of times his songs were played in a commercial, and y represent the number of times his songs were played in a movie.
Since we know Owen's songs were played on 4 more commercials than in movies, we can write the expression
x = y + 4
Owen gets $50 every time one of his songs is played in a commercial and $140 every time one of his songs is played in a movie, so we can add these numbers into the equation below.
140y + 50x = $770
We can use the equation two lines above and substitute it into this equation so it now becomes:
140y + 50(y +4) = 770
Now we operate the equation so it becomes:
140y + 50y + 200 = 770
Now we reduce and add like terms.
190y = 770 - 200 = 570
190y = 570
570 / 190 = 3 (3 movies)
x = y + 4 = 7
y = 3
x = 3 + 4 = 7
So therefore Owen's songs were played 4 times in a commercial (x), and 3 times in a movie. (y)

The regular price of an electric scooter is $290. It is on
sale for 20% off. Sales tax is 7%. What is the cost of the
electric scooter after the discount and sales tax are
applied?
$232.00
$294.06
$310.30
$248.24
Answer:
The cost of the electric scooter after the discount and
sales tax will be: $248.24
Step-by-step explanation:
The regular price of an electric scooter = $290
Discount = 20%
The discount price = 20% × 290
= 20/100 × 290
= $58
The price after the discount = $290 - $58 = $232
Sales tax = 7%
Sales tax amount = 7% × 232
= 7/100 × 232
= $16.24
The cost after the discount and sales tax = $232 + $16.24
= $248.24
Thus, the cost of the electric scooter after the discount and
sales tax will be: $248.24

O No
Answer:
No sir
Step-by-step explanation:
first you will try to get x by its self.
so were it says -5x = 3 you wanna do
+5 +5 on both sides to cancel out 5 so that would be
X = 8 because -5 + 5 is 0 which in this case will be left with X
you already have 8 so x = 8

What is an equation of the line that passes through the point (8,-4) and is parallel to the line x-4y=12?
The equation of the line that passes through the point (8, -4) and is parallel to the line x - 4y = 12 is x - 4y = - 8.
Two lines with slopes m₁ and m₂ are parallel when m₁ = m₂ and perpendicular when m₁*m₂ = -1.
In the question, we are asked for the equation of the line that passes through the point (8, -4) and is parallel to the line x - 4y = 12.
The given line can be shown as:
x - 4y = 12,
or, - 4y = - x + 12,
or, y = x/4 - 12/4,
or, y = x/4 - 3.
Comparing it to the slope-intercept form of a line, y = mx + b, we get the slope, m = 1/4.
The line parallel to this will also have the slope, m = 1/4.
The required line passes through the point (8, -4).
Using the one-point formula, (y - y₁) = m(x - x₁), we can write the required equation as:
y - (-4) = (1/4)(x - 8),
or, y + 4 = x/4 - 2,
or, y = x/4 + 2,
or, x/4 - y = -2,
or, x - 4y = - 8.
Thus, the equation of the line that passes through the point (8, -4) and is parallel to the line x - 4y = 12 is x - 4y = - 8.

Answer:
i think it means to just plot j at -6 on the x axis and 1 up on y axis
Answer:
Step-by-step explanation:
J has coordinates ( 6, 1) when reflected over the x-axis
(x, y) reflected over x-axis becomes ( x, -y)
J' has the coordinates ( 6, -1)
If f(x) = -x + 6, find f(-3).
Find f
The value of function f when x is (-3) is 9.
To solve the value of function for the value of x as -3, we will simply keep the value of x in the equation.
Rewriting the equation
f(x) = -x + 6
Keep the values of x in the above equation
f(x) = - (-3) + 6
Adding the two negative signs, hence, the value will be 3.
f(x) = 3 + 6
Performing addition to find the value of f(x) when value of x is (-3)
f(x) = 9
Therefore, the value of f(x) is 9.

Answer:

Let the amount of work be x.

There are 56 students in a school play. The ratio of boys to girls is 3:5. How many girls are in the school play?
Answer:
35 girls
Step-by-step explanation:
First add the ratios together ( 3+5) this will give you 8. Then divide the total number of students by 8, this will get you 7. Now multiply 7 to 3 and multiply 7 to 5. As the ratio of boy to girl is 3 to 5, to find how many girls are in the school play we multiply 7 to 5. This makes 35 girls.
If you want to check, 7 x 3 =21 boys and 7 x 5=35 girls. 35 +21= 56 (the total number of students).
