7/24.5=7/31.5 is it proportional or not?

15 answers

To determine if two ratios are proportional, we check if they are equivalent.

7/24.5 and 7/31.5 are not equivalent because the numerators (7) are the same, but the denominators (24.5 and 31.5) are different.

Therefore, 7/24.5 is not proportional to 7/31.5.
6.0-4.5÷2
To solve this expression, we start by performing the division operation.

4.5 ÷ 2 = 2.25

Next, we subtract this result (2.25) from 6.0.

6.0 - 2.25 = 3.75

Therefore, 6.0 - 4.5 ÷ 2 equals 3.75.
Do 6.0-4.5
Then divide the answer by 2
To solve the expression 6.0 - 4.5 and then divide the answer by 2, we'll perform the subtraction first.

6.0 - 4.5 = 1.5

Next, we divide this result (1.5) by 2.

1.5 ÷ 2 = 0.75

Therefore, the expression 6.0 - 4.5 ÷ 2 equals 0.75.
Is 3/9=15/45 proportional or not?
To determine if two ratios are proportional, we need to check if they are equivalent or equal.

For 3/9 and 15/45:

To simplify 3/9, we divide both the numerator and the denominator by their greatest common divisor (which is 3):

3 ÷ 3 = 1

9 ÷ 3 = 3

Therefore, 3/9 simplifies to 1/3.

Similarly, to simplify 15/45, we divide both the numerator and the denominator by their greatest common divisor (which is 15):

15 ÷ 15 = 1

45 ÷ 15 = 3

Therefore, 15/45 simplifies to 1/3.

Since both ratios simplify to 1/3, they are equivalent or equal.

Hence, 3/9 is proportional to 15/45.
Is 2/6=33/100 proportional?
To determine if two ratios are proportional, we need to check if they are equivalent or equal.

For 2/6 and 33/100:

To simplify 2/6, we divide both the numerator and the denominator by their greatest common divisor (which is 2):

2 ÷ 2 = 1

6 ÷ 2 = 3

Therefore, 2/6 simplifies to 1/3.

Similarly, no simplification can be done for 33/100 because their greatest common divisor is 1.

Since 1/3 and 33/100 are not equivalent or equal, 2/6 is not proportional to 33/100.
Given the equation y=10x, fill in the missing x-value and y-value
Without specific information or context, it is not possible to determine the missing x and y-values for the equation y=10x. The equation represents a line with a slope of 10, but the specific values for x and y would depend on the context or given conditions.
Oh add this

(5,y)
(x,7)
Given the equation y=10x, we can substitute the given values into the equation to find the missing x and y-values.

For the point (5, y):
y=10(5)
y=50

Therefore, the missing y-value is 50. The coordinates for the first point are (5, 50).

For the point (x, 7):
7=10x
x=7/10
x=0.7

Therefore, the missing x-value is 0.7. The coordinates for the second point are (0.7, 7).
Transform 7x+4y=-5 into slope-intercept form
To transform the equation 7x + 4y = -5 into slope-intercept form (y = mx + b), where m represents the slope and b represents the y-intercept, we need to isolate y on one side of the equation.

7x + 4y = -5

First, let's subtract 7x from both sides:

4y = -7x - 5

Next, divide the entire equation by 4 to isolate y:

y = (-7/4)x - 5/4

Therefore, the equation 7x + 4y = -5 can be written in slope-intercept form as y = (-7/4)x - 5/4.
