Explain:
How do we write algebraic expressions? ( You can explain which keywords tells you to add, subtract, multiply and divide) Give two examples.
Answer:
Step-by-step explanation:Before you can tackle complex word problems, you need to know how to translate simple problems into algebra. Generally, you'll do this by replacing the words with operators that mean the same thing. So for instance, four divided by x could be 4 ÷ x. ÷ and / are just two ways of writing divided. If you were to translate this word for word, you'd change the word times to a multiplication symbol (⋅) and put a plus sign (+) between the four and the two. Your expression would look like this:
The top of a ladder rests at a height of 15 feet against the side of a house. If the base of the ladder is 6 feet from the house, what is the length of the ladder? Round to the nearest foot.
A. 9 ft
B. 14 ft
C. 16 ft
D. 21 ft
Which expression is equivalent to 4/5x + 1 1/5?
A. 1/5 (4x + 1)
B. 2/5 (2x + 3)
C. 4/5 (x + 2)
D. 5/4 (x + 1)
I'd love it if you gave me an explanation for this.
Answer:
The answer would be B!
Step-by-step explanation:
To find which expression is equivalent, do the distributive property.
A. 1/5 * 4x = 4/5x
1/5 * 1/1 = 1/5
4/5x + 1/5 <--- This is wrong!
B. 2/5 * 2x = 4/5x
2/5 * 3/1 = 6/5 = 1 1/5
4/5x + 1 1/5 <--- This is correct!
C. 4/5 * x = 4/5x
4/5 * 2/1 = 8/5
4/5x + 8/5 <--- This is wrong!
D. 5/4*x = 5/4x
5/4 * 1/1 = 5/4
5/4x + 5/4 <--- This is wrong!
Therefore, the answer is B! Hope this helps!
Solve the equation by showing the work
-4x + 2 = -18
Answer:
x = 5
Step-by-step explanation:
-4x + 2 = -18
subtract 2 from both sides
-4x + 2 - 2 = -18 - 2
simplify
-4x = -20
divide both sides by -4
-4x/-4 = -20/-4
simplify
x = 5
hope this helps :) have a nice day !!

The value of x is equal to 148. This is because of the vertical angles theorem.
The vertical angles theorem states that when two angles are vertical to each other (such as the example in this problem), then they are equal to each other.
5.
We know that a line has a angle of 180 degrees. So, to find x, we subtract everything from 180.
180 - 125 - 30 = x
25 = x
8.
We know that given angle in total is equal to 89 degrees. So, to find x, we subtract everything from 89.
89 - 12 - 29 = x
48 = x

Here is Priya's calculation of 906 divided by 3
Priya wrote 320 for the value of 906 +3. Check her answer by multiplying it by 3. What product do you get and what does it tell you about Priya's answer?
correct answer is 302**
Answer:
Her mistake is that she wrote a two in the tenths place and zero in the ones place.
Step-by-step explanation:
3 can't go into zero so she had to write a zero in the tenths place. And 3 can go into 6 two times so she must write a 2 in the ones place.
Hope this Helps :)
