Step-by-step explanation:

Let's solve your system by substitution.

3x−2y=7;y=x+2

Rewrite equations:

y=x+2;3x−2y=7

Step: Solvey=x+2for y:

y=x+2

Step: Substitutex+2foryin3x−2y=7:

3x−2y=7

3x−2(x+2)=7

x−4=7(Simplify both sides of the equation)

x−4+4=7+4(Add 4 to both sides)

x=11

Step: Substitute11forxiny=x+2:

y=x+2

y=11+2

y=13(Simplify both sides of the equation)

Answer:

x=11 and y=13

Step-by-step explanation:

The completed statements with respect to the parts on the number line are;

What is 4 ÷ 1/3; 12

This problem asks how many groups of 1/3 are in 4

The quotient of 4 ÷ (1/3) is; 12

A number line is a visual representation of the set of real numbers. A number line is a straight line on which each point corresponds to a number. The points on the line are evenly spaced, with the distance between two points representing the difference between the numbers.

The question asks how many groups of 1/3 are in 4, which is equivalent to dividing 4 by 1/3, which can be expressed as 4 ÷ 1/3

To divide a number by a fraction, we can multiply the number by the reciprocal of the fraction.

The reciprocal of a fraction is obtained by flipping the numerator and denominator. The reciprocal of 1/3 is 3/1 which is 3. The expression can therefore, be expressed as follows;

4 ÷ (1/3) = 4 × 3 = 12

The quotient of 4 ÷ (1/3) is 12, which indicates that the number of groups of 1/3 in 4 are 12

Answer:

A simple example: Say that f(x) is x+1 and g(x) is x^2. While f(x)g(x) would be (x+1)x^2, f of g of x would be x^2+1. Continuing on with the same example, the f(x)g(x) derivative with the product rule would give x^2+2x(x+1), and the f of g of x derivative would be 2x.

Answer:

A. 7.50+5.25= 12.75........

Answer:

C.

Step-by-step explanation:

Two bots 7.50 each

Three DVDs 5.25 each

2 x 7.50 = 15

3 x 5.25 = 15.75

15 + 15.75 = 30.75

$30.75

The number of nickels are 41 and the number of quarters are 27.

Given that, Angela has a collection of nickels and quarters worth $8.80.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

We know that, a nickel is worth 5 cents and a quarter is worth 25 cents.

Let the number nickels be x and the number of quarters be y.

Now, 0.05x+0.25y=8.80 ----------(I)

x+y=68 ----------(II)

Substitute x=68-y in equation (I), we get

0.05(68-y)+0.25y=8.80

⇒ 3.4-0.05y+0.25y=8.80

⇒ 0.20y=8.80-3.4

⇒ 0.20y=5.4

⇒ y=5.4/0.20

⇒ y=27

Substitute y=27 in equation (II), we get

x=41

Therefore, the number of nickels are 41 and the number of quarters are 27.
