Answer:
C) a + 7
Step-by-step explanation:
To correctly express this algebraic expression we just have to separate the terms, the age of Jose is oue incognita, and to know his age 7 years from now we just have to add the years that we know the age from today, and in this problem they ask us to create an expression that shows his age 7 years from now:
the age is expressed by "a", and 7 is the number of years from now that we want to know his age:
a+7
Is the correct expression.

A recipe calls for 9 tablespoons of milk for every 21 cups of flour. If the chef puts in 168 cups of flour, how many tablespoons of milk must the chef add?
Answer:
The slope is 1/2
Step-by-step explanation:
The distance between two points gives a line
The slope, m of a line is given as
m = (y2 - y1) / (x2 - x1)
points are written as coordinates
(x, y)
Given two points with coordinates
Point one
(5,1) Corresponds to (x1, y1)
Point two
(7,2) corresponds to (x2, y2)
Where;
x1 = the value of the x coordinate at point one = 5
y1 = the value of the y coordinate at point one = 1
x2 = the value of the x coordinate at point two = 7
y2 = the value of the y coordinate at point two = 2
m = (2 - 1) / (7 - 5)
m = 1/2
Therefore, the slope of the line is 1/2
Answer:
straight line
Step-by-step explanation:
243, -81, 27, -9...
Hi there!
To find the answer, you divide one of the numbers by 3, and some others by -3.
I can show you how to do so! :D
243 ÷ -3 = -81
-81 ÷ 3 = 27
27 ÷ 3 = 9
Next three terms -
9 ÷ 3 = 3
3 ÷ 3 = 1
1 ÷ 3 = 0.3333, the 3 is repeating over and over again
I think this is the answer, based off my notes :)
That's your pattern!
Hope this helps!
