Answer:

250 nickles

Step-by-step explanation:

Nickles and dimes are coins with different currency values. One nickel(N) is equal to 5 cents while one dime(D) is equal to 10 cents. The ratio of nickel:dime is 5:7, to put into the equation it will be:

N/D= 5/7

7N=5D   ---> 1st equation

There are 350 dimes, the equation will be:

D=350   ----> 2nd equation

We can find out the number of nickels by substitute the 2nd equation into the first. The calculation will be

7N=5D

N= 5D/7

N=5(350)/7

N=  250

Answer:

Both

Claire

Andre

Neither

Step-by-step explanation:

We have to determine whether each point lies on Claire's line (blue) and whether it lies on Andre's line (black).

Point A is the intersection of both lines, hence the statement represents them both.

Point B only lies on Claire's line.

Point C is the start of Andre's line.

Point D is outside of both lines.

When two equal signs is placed between two algebraic expressions a what is formed
Vikki [24]

If we have two sides equal each other, then we called the statement "equation"

Example:

2x + 3 = 5x - 2 is called an equation

2x + 3 is an algebraic expression

5x - 2 is an algebraic expression

When we put = sign between them, they called an equation

Then when two equal signs are placed between two algebraic expressions, they formed an equation

The answer is an equation
