In the united states, only the metric system of measurement is used. true or false.

Answers

Answer:

The correct answer is FALSE

Step-by-step explanation:

The given statement : In the united states, only the metric system of measurement is used.

We need to find whether the given statement is true or false.

Now, In united states the construction standards using the metric system have not been established.

Therefore, the metric system of measurement is very rarely used in the United States.

So we can say that the given statement : "In the united states, only the metric system of measurement is used" is FALSE.

Hence, the correct answer is FALSE

how many solution exist for each system of equations?

3x-3y=-6

y=x+2

Answers

The second one is already in slope-intercept form.
We need to do a little work on the first one.

3x - 3y = -6

Subtract 3x from each side:

-3y = -3x - 6

Divide each side by -3 :

y = x + 2

That's the first equation. But when you unravel it like this, you find that
it's exactly the same as the second equation. Both of them represent
the same straight line on a graph.  If you graphed both of them, you'd
only see one line !

The 'solution' of a pair of equations is the point on a graph where their
lines cross.  There's no such point here, because each and every point
of the first equation is also a point of the second one. 

This pair (system) of equations has no solution.

This recipe makes 3 portions of potato soup. Richard follows the recipe but wants to make 9 portions.
Complete the amounts of each ingredient that he needs.

Recipe: Serves 3
20 ml oil
30 g onions
400 g potatoes
450 ml milk

Answers

Answer:

60 ml oil, 90 g onions, 1200 g potatoes, 1350 ml milk

Step-by-step explanation:

What you need to do here is multiply all of these ingredients by 3, because the recipe serves 3 and he needs to serve 9, and 9/3 = 3. Therefore, he would have to triple the recipe.
