D) 7 - a

Answers

Answer 1
Answer:

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.
Answer 2
Answer: Seven years from now he will be older so add each year that will pass

a+7

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?

Answers

Thing 1
A: If you use 32 gallons of gasoline you have to use 12 ounces of oil.
B: 6/16 and x/32. You would then cross multiply. 
1A=12 oz
1B=16×2=32 6×2=12
32÷16=2
Since 32÷16=2 then you have to multiply 6 and 2 to get your answer which is 12oz

Can someone explain how I do these problems

the answer is d. the angle that is 140* and the angle it is right next to must equal 180. therefore you subtract 180-140 to get the measure of that interior angle. after doing that, you add the measure of the two interior angles to get the measure of

What is the slope of a line with one point at (5,1) and another point at (7,2)?

Answers

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

Find the next three terms.

243, -81, 27, -9...

Answers

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!
