simplify both sides of the equation.

3/25x + -14/5 = 13/5

add 14/5 to both sides.

3/25x = 27/5

Answer:

x = 18

Step-by-step explanation:

Answer:

x = 18

Step-by-step explanation:

Supplementary angles = 180°

110° + ( 3x + 16° ) = 180

110° + 3x + 16 ° = 180

126° + 3x = 180

3x = 180 - 126

3x = 54°

x = 54/3

x = 18

17. You sell large and small pictures at a fair. You sell a total of 16 pictures and made a total of
$350. If large pictures sell for $25 and small pictures sell for $20. How many of each did you
sell?

Answers

Make a system of equation
Let L be large pictures
Let S be small pictures
You know they add to 16 pictures
You know each cost

(L + S = 16) * 25
25L + 20S = 350
25L + 25S = 400
Subtract (elimination method)
-5S = -50, S = 10
L + 10 = 16, L = 6

Solution: 10 small pictures
6 large pictures

Are 5x + 9 - 2x = 12 and 3x = 3 equivalent equations

Answers

Answer:

Yes

Step-by-step explanation:

If you simplify the 1st equation,

5x + 9 - 2x = 12

Add like terms

3x + 9 = 12  

Subtract the 9 from both sides

3x = 3

It gives you the same equation as the other one

A right cylinder has a height of 8 inches and a volume of 400 cubic inches.
Which measurement is closest to the radius, in inches, of the cylinder?
A. 4
B. 8
С. 16
D. 50

Answers

Answer:

Step-by-step explanation:

its D because 400 divided by 8 is 50

[tex]\boldsymbol{4}[/tex] is closest to the radius, in inches, of the cylinder.

So, option A. is correct.

Volume of cylinder

Height of a cylinder [tex](h)=8[/tex] inches

Volume of a cylinder[tex]=400[/tex] cubic inches

Let [tex]r[/tex] denotes radius of a cylinder.

Volume of a cylinder [tex]=\pi r^2 h[/tex]

[tex]400=\frac{22}{7}r^2 (8)[/tex]

[tex]r^2=15.9\\r=3.99[/tex]

So, [tex]\boldsymbol{4}[/tex] is closest to the radius, in inches, of the cylinder.

So, option A. is correct.

A. 155
B. 205
C. 165
D. 145

Answers

Answer:

its 155

Step-by-step explanation:

360/2

180-25

155

The 155° angle in the piece that is left if the piece of cake with a 25° angle is eaten option (A) is correct.

What is a circle?

It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).

We have half of a circular cake is left after a party.

A piece of cake with a 25° angle is eaten.

We know the circle is a complete revolution of lines that joins from a fixed point to point at a certain distance; makes an angle 0f 360°

half of a circular cake with an angle = 360°/2  ⇒ 180°

25° angle piece eaten, then the remaining left portion:

= 180° - 25°

= 155°

Thus, the 155° angle in the piece that is left if the piece of cake with a 25° angle is eaten.

Estimate the perimeter and the area of the shaded figure

Show how you got your answer

Answers

Answer:

Perimeter = 16 feet

Total Surface Area = 24 sq ft.

Step-by-step explanation:

Let's assume that each square is equal to 1 foot. Using this we can estimate the perimeter and area as the following. For perimeter, we simply add all the squares distances surrounding the shaded object.

Perimeter = 16 feet (4 feet for the top and bottom and 2 feet every diagonal)

For the area, we need to calculate the area of the square in the middle and then the area of the two triangles.

Square = L * W

Square = 4 * 4

Square = 16 sq ft

Triangle = 0.5 * Base * Height

Triangle = 0.5 * 4 * 2

Triangle = 4 sq ft

Both triangles = 4 sq ft * 2 = 8 sq ft.

Now we add both area totals:

Total Surface Area = 16 + 8

Total Surface Area = 24 sq ft.
