Find the missing values for 7/8= ×/8
Answers
if x/y=z/y where y=y, then x=z
we have
7/8=x/8
8=8
therefor 7=x
the missing value=7

The slope-intercept form: y = mx + b
m - a slope
b - y-intercept
We have a slope m = 1/4. Substitute: y = 1/4 x + b
We know, the line passes through point (8, 3) → x = 8, y = 3.
Put the values of x and y to the equation of the line:
1/4 · 8 + b = 3
2 + b = 3 |-2
b = 1
Answer: y-intercept is (0, 1)
The y-intercept of a line with a slope of 1/4 and which passes through point (8,3) is 1.
What is the y-intercept of the given line?
The equation of a line in slope in slope intercept form is expressed as:
y = mx + b
Where m is slope and b is the y-intercept.
Given the data in the question:
The line has a slope of 1/4 and passes through point (8,3).
x = 8, y = 3, m = 1/4
Plug the given values into the above formula and for the y-intercept 'b'.
y = mx + b
3 = (1/4 × 8 ) + b
Solve for b:
3 = 8/4 + b
3 = 2 + b
3 - 2 = 2 - 2 + b
1 = b
b = 1
Therefore, the y-intercept is 1.

To find the answer to this problem, you should work it backwards.
Kyle had 18 jujubes in his possession before he gave some to Kim. Since Jen ate half and gave half to Kyle, 18 is half of the number that Jen had total. 18 divided by 1/2 will be 36. Jen had a total of 36, but she ate 18. And since Sam gave Jen 36, which was half of what he had, Sam had a total of 72 jujubes.

Answer:
3:5 is the ratio.
Step-by-step explanation:
The ratio of the number of steps of father to number of steps of son is 3:5.
The table forms as follows:
Steps by father Steps by son
3 5
6 10
9 15
12 20
15 25
a) The ratio of the number of steps of father to number of steps of son will be 3:5.
b) The table forms as follows:
father son
3 5
6 10
9 15
12 20
15 25
a) We can continue finding equivalent ratios by multiplying both sides of the ratio by different numbers, such as 3, 4, or any other value.
Multiply the first term by 2 to get 3 * 2 = 6. Multiply the second term by 2 to get 5 * 2 = 10.
- The equivalent ratio is 6:10.
In the ratio table, we can observe that the values of the ratios are always in the form of a fraction or as a simplified fraction.
=The ratios we have found so far, such as
3:5 and 6:10, = 3/5 and 3/5 respectively.
Thus the ratio of the number of steps of father to number of steps of son is 3:5.
b) The table forms as follows:
father son
3 5
6 10
9 15
12 20
15 25
