Solve the system of equations using substitution y=7 y=2x-5

Mathematics
1 answer:
anzhelika [568]1 year ago
5 0

y= 7 (a)

y= 2x-5 (b)

Replace (a) on (b) ans solve for x:

7 = 2x-5

Add 5 to both sides of the equation:

7+5 = 2x -5 +5

12 = 2x

Divide both sides by 2

12/2 = 2x/2

6 = x

Solution:

x=6, y=7

A roll of quarters is shaped like a cylinder and contains 40 each quarter has a thickness of 1.75 and a diameter of 24.26 mm Wha
jarptica [38.1K]

Answer:

D) 32,357mm^3

Step-by-step explanation:

Given

Quarters = 40

Thickness = 1.75mm

diameter = 24.26mm

First, we calculate the volume of 1 roll.

The volume of the cylinder is:

V = \pi r^2h

Where

r = \frac{1}{2} * diameter

r = \frac{1}{2} * 24.26mm

r = 12.13mm

And the thickness represents the height.

So:

The volume is:

V = 3.142 * 12.13^2 * 1.75

V = 809.03mm^3

The volume of the 40 is:

Roll= 40 * 809.03mm^3

Roll=32361.20mm^3

The closest option is (d):

lesya [120]

Answer:

2^4

2 * 2 * 2 * 2

Step-by-step explanation:

In the question above :

Write an exponential expression:

Base = number between 0 and 10

Exponent = number different from the base between 0 and 10

Let base = 2

Let exponent = 4

Hence, exponential expression will be

Base^exponent

2^4 (standard form)

Expanded form:

2 * 2 * 2 * 2 (multiply 2 in 4 places)

If w= the weight of trout. Which algebraic expression represents the phrase below?
konstantin123 [22]

Product means multiplication.

Given w= weight of a trout.

So, we need to convert "product of 16 and weight of trout: w " into an algebraic expression.

So, product of 16 and w can be written as 16*w or simply 16w.

Hence, B is the correct choice.
