A coach buys a uniform and a basketball for each of the 15 players on the team. Each basketball costs $9. The coach spends a total of $420 for uniforms and basketballs. What is the cost of one uniform? Use a strategy that makes sense to you. Show your thinking!
Answer:
$19
Step-by-step explanation:
Since there are 15 players and he bought a basketball for each of them, he bought 15 basketballs in total.
The price of a basketball costs $9.
The total price of all 15 basketballs = $9 * 15 = $135.
He spent $420 on uniforms and basketballs, and he spent $135 on basketballs.
Thus, he spent $420 - $135 = $285 on uniforms.
As he bought a uniform for each of the 15 players, he bought 15 uniforms in total.
The price of 15 uniforms is $285.
The price of 1 uniform is $285 ÷ 15 = $19.
Answer:
$19.
Step-by-step explanation:
Let x be the cost of a uniform:
Then we have 15 (x + 9) = 420.
We can divide both side by 15, getting x + 9 = 28.
Then, we can subtract both sides by 9, getting x = 28 - 9 = 19.

Step-by-step explanation:
Samantha's mother spent $78 at a farmers market. She bought the same number of pounds of apples for $1.50 per lb as tomatoes for $2.50 per lb. She also bought half that weight of a farmers cheese that sold for $4.00 per lb. The number of pounds of peaches she bought for $3.00 per lb was one more pound than the farmers cheese. How many pounds of each product did Samantha's mother buy?
Answer:
The number of pounds of apples she bought = 10 pounds
The number of pounds of tomatoes she bought = 10 pounds
The number of pounds of the farmers cheese she bought = 5 pounds
The number of pounds of peaches she bought = 6 pounds
Step-by-step explanation:
The given information are;
The amount that Samantha's mother spent in the market = $78
The number of pounds of apples she bought = The number of pounds of tomatoes she bought
The number of pounds of the farmers cheese she bought = 1/2 of the number of pounds of apples she bought
The number of pounds of peaches she bought = 1 + 1/2 of the number of pounds of apples she bought
The price of the apples = $1.50
The price of the tomatoes = $2.50
The price of the farmers cheese = $4.00
The price of the peaches = $3.00
If we put the number of pounds of the apples she bought = X, we have
X×$1.50 + X×$2.50 + 1/2×X×$4.00 + (1 + 1/2×X)×$3.00 = $78.00
Which gives;
X×$1.50 + X×$2.50 + 1/2×X×$4.00 + $3.00+ 1/2×X×$3.00 = $78.00
[tex]\dfrac{X \times \$15.00 + \$ 6.00}{2} = \$ 78[/tex]
X × $15.00 + $6.00 = $78 × 2 = $156.00
X × $15.00 + $6.00 = $156.00
X × $15.00 = $156.00 - $6.00 = $150.00
X = $150.00/($15.00) = 10 pounds
Therefore;
The number of pounds of the apples she bought = X = 10 pounds
The number of pounds of apples she bought = 10 pounds
The number of pounds of tomatoes she bought = The number of pounds of apples she bought = 10 pounds
The number of pounds of tomatoes she bought = 10 pounds
The number of pounds of the farmers cheese she bought = 1/2 of the number of pounds of apples she bought = 1/2 of 10 = 1/2×10 = 5 pounds
The number of pounds of the farmers cheese she bought = 5 pounds
The number of pounds of peaches she bought = 1 +The number of pounds of the farmers cheese she bought = 1 pound + 5 pounds = 6 pounds
The number of pounds of peaches she bought = 6 pounds.
The solution is: Samantha´s mother bought:
10.71 Lbs of apples10.71 Lbs of tomatoes5.36 Lbs of farmers cheese6.36 Lbs of peachesAs the question of the problem is" How many pounds of each product Samantha´s mother bought" it is convenient to call:
x quantity of pounds of apple ( the same as tomatoes )Samantha´s mother bought y quantity of pounds of farmers cheese Samantha´s mother bought z quantity of pounds of peaches Samantha´s mother boughtAccording to that:
Spent
She spent 78 $ buying
1.50× x + 2.50×x + 4× y + 3 × z = 78 (1)
Now y = x/2 and z = y + 1
By substitution in equation (1) we get
3.50× x + 4×(x/2) + 3× [( x/2 ) + 1 ] = 78
Solving for x
5.50×x + (3/2)×x + 3 = 78
11×x + 3×x + 6 = 156
14×x = 150
x = 10.71 Lbs
y = 10.71/2 y = 5.36 Lbs
and z = 5.36 + 1 = 6.36 Lbs
z = 6.36 Lbs
A bird is flying 33 feet above sea level, a diver is 20 feet below sea level. What
is the distance between the bird and diver
Answer:
53 feet
Step-by-step explanation:
If the bird is flying 33 feet above sea level, and the diver is 20 feet below it would be 53 because you have to imagine right at sea level is a zero and 20 below with 33 above would equal 53
Answer:
53
Step-by-step explanation:
Distance is always positive, therefore the distance below and the distance above are added together: 33+20=53
Use the given conditions to write an equation for the line in point-slope form.
Slope = 3, passing through (-7,8)
Step-by-step explanation:
Hey there!
The given slope is; 3. And passing through point (-7,8).
Now,
Using one point formula.
[tex](y - y1) = m(x - x1)[/tex]
Put all values to find equation.
[tex](y - 8) = 3(x + 7)[/tex]
Simplify them to get answer.
[tex](y - 8 )= 3x + 21[/tex]
[tex]3x - y + 21 + 8 = 0[/tex]
[tex]3x - y + 29 = 0[/tex]
Therefore the required equation is 3x-y+29=0.

The coordinates of the midpoint of GH are M (8,0) and the coordinates of one endpoint are H(-2, 9). The coordinates of the other endpoint are
Answer:
G(18,-9)
Step-by-step explanation:
The coordinates of the midpoint of GH are M (8,0) and the coordinates of one endpoint are H(-2, 9). We need to find the coordinates of G. Let G is (x,y).It can be done using mid point formula i.e. [tex](\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]
So,
[tex]8=\dfrac{x-2}{2}\ \text{and}\ 0=\dfrac{9+y}{2}\\\\16=x-2\ \text{and}\ y=-9\\\\x=18\ \text{and}\ y=-9[/tex]
Hence, the coordinates of the other point is (18,-9).
Jennifer and Kamlee are walking to school. After 20 minutes, Jennifer has walked 4/5 miles. After 25 minutes, Kamlee has walked 5/6 miles. Find their speed in miles per hour
Answer:
Jennifer's speed is 2.4 miles/hour
Kamlee's speed is 2 miles/hour
Step-by-step explanation:
To find their speed,
Speed can be determined from the formula below,
[tex]Speed = \frac{Distance}{Time}[/tex]
Also, to determine the speed in miles per hour (miles/hour), we will convert the time spent by each of them to hour (NOTE: 60 minutes = 1 hour)
For Jennifer,
Distance = 4/5 miles
Time = 20 mins (Convert to hour)
∴Time = (20/60) hour = 1/3 hour
Hence,
[tex]Speed = \frac{Distance}{Time}[/tex]
[tex]Speed = \frac{4/5 miles}{1/3hour}[/tex]
[tex]Speed = \frac{4}{5} \times \frac{3}{1}[/tex]
[tex]Speed = \frac{12}{5}[/tex]
[tex]Speed = 2.4 miles/hour[/tex]
Hence, Jennifer's speed is 2.4 miles/hour
For Kamlee,
Distance = 5/6 miles
Time = 25 minutes (Convert to hour)
Time = (25/60) hour = 5/12 hour
Hence,
[tex]Speed = \frac{Distance}{Time}[/tex]
[tex]Speed = \frac{5/6miles}{5/12 hour}[/tex]
[tex]Speed = \frac{5}{6} \times \frac{12}{5}[/tex]
[tex]Speed = 2 miles/hour[/tex]
Hence, Kamlee's speed is 2 miles/hour

X would have to equal 6 or greater as if x was 5
5+3 is the same as 8
Answer:
I would say no.
Step-by-step explanation:
If x would be 5, then the greater than sign would turn into a equal sign. This is because 5 + 3 = 8. So this (x + 3 > 8) would turn into this (x [or 5] = 8).
