Answer:

x=5

Step-by-step explanation:

Since the triangles are similar we can use ratios to solve

4.5     7.5

---- = ------

3            x

Using cross products

4.5x = 3 * 7.5

4.5x = 22.5

Divide each side by 4.5

x = 22.5/4.5

x=5

If the product of 1/2 and 2/5 is subtracted from the sum of 1/2 and 2/5 what is the difference
kozerog [31]

Answer:

7/10

Step-by-step explanation:

Lets set up this word problem as an equation to make it easier to solve.

1/2+2/5 - 1/2 x 2/5

<em>Now lets solve using PEMDAS:</em>

<em />

1/2+2/5 - 1/2 x 2/5           1/2 x 2/5 = 1/5

1/2 + 2/5 - 1/5                  1/2 + 2/5 = 9/10

9/10 - 1/5 = 7/10

What is the surface area of a sphere with a radius of 9 units?
Vinvika [58]

Answer:

see explanation

Step-by-step explanation:

The surface area (A) of a sphere is calculated as

A = 4πr² ← r is the radius, here r = 9, thus

A = 4π × 9² = 4π × 81 = 324π ≈ 1017.9 units²

Given a system of linear equations; explain your strategy for solving the system, show the math required to solve the problem, a
labwork [276]

The solution is (x, y) = (2, 3)

<em><u>Solution:</u></em>

<em><u>Given equations are:</u></em>

y = 3x - 3 ------- eqn 1

y = 2x - 1 ---------- eqn 2

We can solve the equations by substitution method

In eqn 1, we have y equals 3x - 3

If we substitute this in place of y in eqn 2, we can get value of "x"

Substitute eqn 1 in eqn 2

3x - 3 = 2x - 1

Move the variables to one side and constants to other side

3x - 2x = -1 + 3

<h3>x = 2</h3>

Substitute x = 2 in eqn 1

y = 3(2) - 3

y = 6 - 3

<h3>y = 3</h3>

Thus the solution is (x, y) = (2, 3)
