part one of this would be x=6;

2x6 is 30

30+5 is 35

part two of this would be x=20;

20x4 is 80

80-7 is 73

Answer:

x = 15 and x = 20

Step-by-step explanation:

(2)

35 = 2x + 5 ( subtract 5 from both sides )

30 = 2x ( divide both sides by 2 )

15 = x

(3)

4x - 7 = 73 ( add 7 to both sides )

4x = 80 ( divide both sides by 4 )

x = 20

Answer:

V = 32

Step-by-step explanation:

Comment

I think you should try this one yourself after I post my answer. Estimation is a very valuable tool -- the more you use it, the handier it gets.

Formulas

pi = 3

V = 4/3 * pi * r^3

Givens

r = 2

pi = 3

Solution

V = 4/3 * pi * r^3 Substitute values for symbols

V = 4/3 * 3 * 2^3 Cancel the 3s

V = 4 * 2^3 Expand the 2s

V = 4 * 2 * 2 * 2 Find V

V = 32

A circular mirror has a diameter of 12 inches.what is the area, in square inches, of the mirror.

navik [9.2K]

Answer: The area of the mirror is 113.14 sq. inches [approx.].

Step-by-step explanation: Given that a circular can till 375 ft² of land in 15 min.

We are to find the area of the mirror in square inches.

The AREA of a circle with radius 'r' units is given by

$A=\pi r^2.$

The diameter of the circular mirror is 12 inches, so the radius of the mirror will be

$r=\dfrac{12}{2}=6~\textup{inches}.$

Therefore, the area of the circular mirror is

$A=\pi r^2=\frac{22}{7}\times 6^2=\dfrac{22\times 36}{7}=113.14~\textup{sq inches}~\textup{[approx.]}$

Thus, the area of the mirror is 113.14 sq. inches [approx.].

The slope-intercept from of the equation of a line that passes through (-2,-13) is y = 5x – 3. What is the point-slope from of t

lisov135 [29]

Answer:

y + 13 = 5(x + 2)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

given y = 5x - 3 with m = 5 and (a, b) = (- 2, - 13), then

y +13 = 5(x + 2) ← in point- slope form
