Answer:
x -2 = 3x +2
Step-by-step explanation:
For the purpose, we use math symbols to express the relation described by the English.
<h3>Translation</h3>
When x represents "a number," we have ...
- two less than a number: x -2
- the product of 3 and the number: 3x
- 2 more than the product: 3x +2
- is the same as: =
Then the English description can be translated to ...
x -2 = 3x +2
__
<em>Additional comment</em>
Adding -2-x to both sides gives ...
-4 = 2x
-2 = x . . . . . divide by 2
The number is -2.
Answer:
420 - x grams.
Step-by-step explanation:
Aderyn is making a vegetable stew for = 6 people.
A recipe indicates that 5 ounces of finally diced onions are needed for = 2 people
1 ounce = 28 grams.
So for 1 people onions are needed = 5/2 = 2.5 ounces or 70 grams.
Therefore, finally diced onion are needed for 6 people = 70 × 6 = 420 grams.
Aderyn needs total 420 grams of diced onion to make her vegetable stew for 6 people.
Let she has already prepared some diced onions = x
then she needs more to make her vegetable stew = 420 - x.
Step-by-step explanation:
50, 60 , 70 can be three angles in a triangle
For x=5 y=4 so we can calculate the slope m=(y1-y)/(x1-x)=(5-0)/(4-0)=5/4
then use (y-y1)=m(x-x1) and you get
y=(5/4)x-5
Isolate the variable by dividing each side by factors that don't contain the variable.
x = 2 √ 3 , − 2 √ 3
