Answer:

x = 8

Step-by-step explanation:

Since the sum of all angles of a parallelogram is equal to 360 degrees, <Z + <Y is half of the parallelogram, and therefore <Z + <Y = 180 degrees.

16x-4 + 7x = 180, combine like terms

23x - 4 = 180, add 4 on both sides (isolate variable)

23x = 184, divide 23 on both sides

x = 8

What is the solution to 3x + 5 > or equal to 7

dem82 [27]

Answer:

$x \geq\frac{2}{3}$

Step-by-step explanation:

The question is $3x+5 \geq 7$

We simply take the numbers to one side and variables to one side and solve via algebra (shown below):

$3x+5 \geq 7\\3x \geq 7-5\\3x \geq 2\\x \geq\frac{2}{3}$

This range of values is the solutions of the inequality.

Answer:

$\frac{-50}{54} - \frac{40}{100} +1.65 = 0.32$

Step-by-step explanation:

First of all, let us lay out the problem clearly:

$\frac{-50}{54} - \frac{40}{100} +1.65$

This can be solved using a calculator, by first simplifying the individual fractions first, to decimals, then computing the addition and subtraction.

using your calculator, punch (-50 ÷ 54), your results should be:

-50 ÷ 54 = -0.93

Next, punch ( 40 ÷ 100), you should get 0.4

Now, join the individual results together to get:

- 0.93 - 0.40 + 1.65

Finally, still using the calculator, input the values as shown:

- 0.93 - 0.40 + 1.65 = 0.32

arman needs 4 1/2 inches of cable to make A,3 3/4 inches to make B, and 5 1/8 inches to make C. He used a 12 inch piece of cable

Kaylis [27]

4 1/2 + 3 3/4 = 4 2/4 + 3 3/4 = 7 5/4 = 8 1/4...what he needs for A and B

He used 12 inches of cable...
12 - 8 1/4 = 11 4/4 - 8 1/4 = 3 3/4....length left after A and B are made

he doesn't have enough to make the last one...
5 1/8 - 3 3/4 = 41/8 - 15/4 = 41/8 - 30/8 = 11/8 = 1 3/8....he is short by 1 3/8 inches

Height=20<br>diameter=14cm<br>find tsa

dusya [7]

Answer:

Let the radius of the cylinder be r and the height be h.

Curved surface area of a cylinder = 2 π r h

Curved surface area of a cylinder = 2 π r h= 2 × 22 / 7 × 7 × 20 = 880 cm^2.

Or of an:

Acute Isosceles Triangle

Side a = 20

Side b = 20

Side c = 14

Angle ∠A = 69.513° = 69°30'46" = 1.21323 rad

Angle ∠B = 69.513° = 69°30'46" = 1.21323 rad

Angle ∠C = 40.975° = 40°58'29" = 0.71514 rad

Area = 131.14496

Perimeter p = 54

Semiperimeter s = 27
