proportional or not proportional?
Answer:
Proportional
Step-by-step explanation:
The relationship is proportional because starting at (0,0) there's a constant rate between the number of plants and the number of roses. We can represent this proportional relationship as y=5x where k=5, the constant of proportionality.

A. The constant ratio of y/x is 12/5
Step-by-step explanation:
The ratio of y to x is constant which is 12/5. Hence option A is the correct option.
What is a constant?
The term "constant" has several meanings in mathematics. When used as a noun, it can have any of the following two meanings: a constant, clearly defined number or another immutable mathematical object.
Given table is
x y
5/6 2
25/6 10
125/6 50
625/6 250
When x = 5/6 and y = 2:
x/y = (5/6)/2 = 5/12
∴y/x = 5/12
When x = 25/6 and y = 10:
x/y = (25/6)/10 = 25/60 = 5/12
∴y/x = 5/12
When x = 125/6 and y = 50:
x/y = (125/6)/50 = 125/300 = 5/12
∴y/x = 5/12
When x = 625/6 and y = 250:
x/y = (625/6)/250 = 625/1800 = 5/12
∴y/x = 5/12

Answer: 2 and
Step-by-step explanation: equation 2:
3(3x+4)-5=9x-2
9x+12-5=9x-2
9x+7=9x+-2
Subtract both sides by 9x
7=-2
This Is not true therefore there is no solution
equation 3:
3(3x+4)-5=-3x+4
9x+12-5=-3x+4
9x+7=-3x+4
12x=-3
divide both parts by -3

In baseball, each time a player attempts to hit the ball, it is recorded. The ratio of hits compared to total attempts is their batting average. Each player on the team wants to have the highest batting average to help their team the most. For the season so far, Jana has hit the ball 12 times out of 15 attempts. Tasha has hit the ball 9 times out of 10 attempts. Which player has a ratio that means they have a better batting average?

How can you use mental math and the inverse property of addition to find the sum [5.5+(-2.3)] +(-5.5 + 2.3)?
Answer:
To use mental math and the inverse property of addition to find the sum [5.5+(-2.3)] +(-5.5 + 2.3), you can use the following steps:
Rewrite the expression as [5.5+(-2.3)] +(-5.5) + 2.3.
Use the inverse property of addition to rewrite (-5.5) as 5.5, so the expression becomes [5.5+(-2.3)] +(5.5) + 2.3.
Use the inverse property of addition again to rewrite (-2.3) as 2.3, so the expression becomes [5.5+2.3] +(5.5) + 2.3.
Use the associative property of addition to rearrange the terms in the expression, so it becomes 5.5 + 2.3 + 5.5 + 2.3.
Use mental math to add the terms, which gives you a result of 15.8.
Therefore, the sum of [5.5+(-2.3)] +(-5.5 + 2.3) is 15.8.

What is the maximum number of 2cm cubes that can fit into a box measuring 10cm by 8cm by 5cm?
Answer: The volume of box is 6×8×10 cm^3
All of 6,8 and 10 are divisible by 2 so your cubes will fill the box, the volume of the cube is 2×2×2=8 cm^3 divide the volume of the box by 8; number of cubes fitting in the box is 6×10=60
Step-by-step explanation:All of 6,8 and 10 are divisible by 2 so your cubes will fill the box, the volume of the cube is 2×2×2=8 cm^3 divide the volume of the box by 8; number of cubes fitting in the box is 6×10=60
Answer:
50 cubes
Step-by-step explanation:
The maximum number of 2cm cubes that can fit into a box measuring 10cm by 8cm by 5cm is 50 cubes.
You can find this by dividing the total volume of the box (10 x 8 x 5 = 400 cm^3) by the volume of a single cube (2 x 2 x 2 = 8 cm^3). So 400cm^3 / 8cm^3 = 50 cubes.
Hence, The maximum number of 2cm cubes that can fit into a box measuring 10cm by 8cm by 5cm is 50 cubes.

Answer:
4(x-1)+9=17
Step-by-step explanation:
3(-2x+1) + 5 = 3x-4-5x
expand
-6x + 3 + 5 = 3x-4-5x
-6x + 8 = -2x - 4
add 2x to both sides to put all x values + coefficients on one side
-4x + 8 = -4
subtract 8 from both sides to isolate x and its coefficient
-4x = -12
divide both sides by -4 to isolate x
x = 3
plug x=3 into each option to see if it works
1. 5(3+3)-4 = 30-4 = 26 != 10
2. 2(3+1) = 8 != 4
3. 4(3-1)+9 = 17 = 17
4. 4(3)+7 = 19 != 3+8 = 11

Kado spent 1 2/3 hours painting a fence. Then he spent 4/5 of an hour walking his dog. How much longer did he spend painting than walking? Orleans chose C as the correct answer.How did she get that answer?
Answer: B, 13/15
Step-by-step explanation: If you multiply both to 15, you will get 1 10/15 and 12/15 if you then subtract the two of them you will be left with
13/15.
Orleans might have got the answer from subtracting wrong or adding them together.
Hope this helps! :)
Orleans must have chosen C as the correct answer, which is 13/15 hours. This means that Kado spent 13/15 hours longer painting the fence than walking his dog.
To find out how much longer Kado spent painting than walking his dog, we need to calculate the difference between the time he spent painting and the time he spent walking his dog.
Kado spent 1 2/3 hours painting the fence.
He spent 4/5 of an hour walking his dog.
To make the calculation easier, let's convert 1 2/3 hours into an improper fraction:
1 2/3 = (3*1 + 2)/3 = 5/3 hours
Now, the time difference is:
Time spent painting - Time spent walking
= (5/3) - (4/5)
To subtract fractions, we need to find a common denominator, which in this case is 15 (the least common multiple of 3 and 5):
= (5/3)(5/5) - (4/5)(3/3)
= 25/15 - 12/15
Now, we can subtract the fractions:
= (25 - 12)/15
= 13/15 hours
Orleans must have chosen C as the correct answer, which is 13/15 hours. This means that Kado spent 13/15 hours longer painting the fence than walking his dog.
