Step-by-step explanation:
Me up rich goes to the skate park and tents a skateboard for 4.00 per hour they make him rent a helmet for one time 6.00 fee if he only has $30 to spend at the park then select the equation that can be used to calculate h the number of hours he can rent the skateboard
Let, x be the maximum hours he can rent skate board and helmet.
So, total price :
T = 4x + 6x
Now, it is given that he has only $30.
Therefore,
Total price should be less than or equal to $30.
4x + 6x ≤ 30
10x ≤ 30
x ≤ 3
Therefore, the maximum number of hours he can rent the skateboard is 3 hours.
Hence, this is the required solution.

A store sells a 33-pound bag of oranges for \$ 3.60$3.60 and a 55-pound bag of oranges for \$ 5.25$5.25. What is the difference between the price per pound for the 33-pound bag of oranges and the price per pound for the 55-pound bag of oranges?
Answer:
0.01364
Step-by-step explanation:
It is given that,
A store sells a 33-pound bag of oranges for $3.60 and a 55-pound bag of oranges for $5.25.
Price per pound of 33 pound bag is 3.60/33 = 0.10909 price per pound
Price per pound of 55 pound bag of oranges is 5.25/55 = 0.09545 price per pound
Difference between price per pound for the 33-pound bag of oranges and the price per pound for the 55-pound bag of oranges is :
D = 0.10909 - 0.09545
D = 0.01364
Therefore, this is the required solution.

solve the liner equation 3(2x-14)+x=15-(-9x-5)
PLEASE HELP! DO NOT PUT A SILLY AWSER I WILL REPORT YOU!
Answer:
x= -31
Step-by-step explanation:
Let's solve your equation step-by-step.
3(2x−14)+x=15−(−9x−5)
Step 1: Simplify both sides of the equation.
3(2x−14)+x=15−(−9x−5)
3(2x−14)+x=15+−1(−9x−5)(Distribute the Negative Sign)
3(2x−14)+x=15+−1(−9x)+(−1)(−5)
3(2x−14)+x=15+9x+5
(3)(2x)+(3)(−14)+x=15+9x+5(Distribute)
6x+−42+x=15+9x+5
(6x+x)+(−42)=(9x)+(15+5)(Combine Like Terms)
7x+−42=9x+20
7x−42=9x+20
Step 2: Subtract 9x from both sides.
7x−42−9x=9x+20−9x
−2x−42=20
Step 3: Add 42 to both sides.
−2x−42+42=20+42
−2x=62
Step 4: Divide both sides by -2.
−2x
−2

an object is moving at a speed of 4 yards every 6.5 days. express this speed in centimeters per minute. round your answer to the nearest hundredth
Answer:
0.0390cm/minStep-by-step explanation:
We are expected to do a unit conversion here.
let us convert days to minutes first
6.5days to minutes
1 day has 1440miuntes
6.5 days has x minute
cross multiply we have
x=6.5x1440
x=9360minute
let us convert yards to cm
1 yard to 91.44 cm
4 yards has xcm
cross multiply we have
x=4x91.44
x=365.76cm
the speed in cm per mins is
speed=365.76/9360m
speed=0.0390cm/min

Step-by-step explanation:
In a function the x values cannot repeat. Look at each answer choice and see if an x repeats:
The first choice (top left) has the x value, -6, repeating. It cannot be a function.
The second choice (top right) does not have an x value repeat. This makes it a function!
The third choice, (bottom left) does not have an x value repeat. This makes it a function!
The fourth choice, (bottom right) does not have an x value repeat. This makes it a function!
List the following in order from least steep to most steep.
f(x)= -3/4x
g(x)= -5x
h(x)= 5/7x
j(x)= 11/3x
Answer:
h(x), f(x), j(x), g(x)Step-by-step explanation:
Given functions
f(x)= -3/4x g(x)= -5x h(x)= 5/7x j(x)= 11/3xTo compare steepness we'll compare absolute values of slopes
The steepness increases as the slope increases
The slopes are
3/4, 5, 5/7, 11/3Comparing the fractions
3/4 = 21/28, 5/7 = 20/28, so 3/4 > 5/7And
11/3 < 4So the order is
5/7 < 3/4 < 11/3 < 5As functions, the order is
h(x), f(x), j(x), g(x)Given that f(x)=2x-1, find f(3)
Answer:
5
Step-by-step explanation:
Put 3 where x is and do the arithmetic.
f(x) = 2x -1
f(3) = 2·3 -1 = 6-1
f(3) = 5

a rectangle has a width of 2x + 1 and a length of 6X which expression describes this area
Given parameters:
Width = 2x + 1
Length = 6x
Unknown:
Expression for the area = ?
Solution:
The area of a rectangle is the space it occupies,
Area of rectangle = length x width
Input the parameter and solve;
Area of rectangle = 6x(2x + 1)
= 12x² + 6x
The area of the rectangle is 12x² + 6x

The resulting value for the given sum of trignometry identity is -2
Trigonometry identityTrigonometry identity are written in tems of sine, cosine and tangent
According to the trigonometry identity
sec theta = 1/costheta
cot theta = 1/tantheta
Given the trigonometry expression
sec 180 + sin 270 - tan 180 + cot 270
This can also be written as;
1/cos180 + sin270 - tan 180 + 1/tan270
= -1/cos0 + (-sin90) - tan0 +1/tan90
= -1 - 1 - 0 +1/∞

= -2
Hence the resulting value for the given sum of trignometry identity is -2

In △FGH, FH ≅ FG. Which angles are congruent? Select both angles that are congruent
angles FGH and FHG
Step-by-step explanation:
Since this is a triangle, and the question states that FH=FG, you know that the triangle is an isosceles triangle. If you use an isosceles triangle, you know that the bottom two angles are the same degrees. Since the F is the same for both lines, you can determine that F is the top point of the triangle. As such, is you draw the triangle out, you will find the answer is angles FGH and FHG

Let's see what to do buddy...
_________________________________
Step (1)
We know that the sum of the interior angles of any n-sided figure is obtained from the following equation :
[tex](n - 2) \times 180[/tex]
Our figure has 5 sides ;
So , sume the interior angles of it equals :
[tex](5 - 2) \times 180 = 3 \times 180 = 540 \\ [/tex]
_________________________________
Step (2)
First look at the photo which I post.
According it we have :
[tex](180 - x) + 120 + 85 + (2x - 10) + 90 = 540 \\ [/tex]
[tex]2x - x + 475 - 10 = 540[/tex]
[tex]x + 465 = 540[/tex]
Subtract the sides of the equation minus 465 :
[tex]x = 540 - 465[/tex]
[tex]x = 75[/tex]

And we're done.

Hello.
The answer is choice A. angle 1 = 118, angle 2 = 118
Explanation:
The four angles above are congruent (meaning the same) to the ones beneath.
Angles 1 and 2 are also congruent, so they will measure the same.
Lets label the angles above A, B, C, D. B being the known angle, which is 118°. The angles beneath can be labelled E, F, G, H.
∠B ≅ ∠D
∠ABCD ≅ ∠EFGH
∠BD ≅ ∠FH
FH (or 1 and 2) equal 118.
