Find the value of X, Z and Y.

Mathematics
1 answer:
FromTheMoon [43]3 years ago
6 0

Answer:

x = 5; y = 138, z= 42

Step-by-step explanation:

4x- 17 = 3 [ opposite sides of a parallelogram are equal]

4x = 3+ 17 = 20; X= 20/4 = 5

138 + Z = 180( angle on a straight line)

Z is an alternate angles to the remaining angle off 138 forming the straight line.

z= 180-138 = 42 degrees

Y = 138 [ opposite angles of a regular quadilareral been equal]

Need help presenting this solution on and number line and in interval notation. (I’m absolutely clueless haha)
beks73 [17]

Since the number is a fraction make a number line using fractions. The inequality sign includes being equal to, so add a solid dot on -5/2 and since x is less than that, draw an arrow pointing to the left.

See attached drawing.

For interval notation since x can be any number less than or equal to -5/2 it would be written as (-∞, -5/2]

What is the height of the cone below?<br><br> V = 45 in^3<br><br> B = 5in^2
Lapatulllka [165]

Answer:

The height of the cone is h = 27

Step-by-step explanation:

<u>Formula:</u>-

Step 1:-

The volume of the cone is  V=\frac{1}{3} (base)(height)

Given volume is V= 45 in^ 3

Given base of the cone is B= 5 in^2

<u>Step 2</u>:-

by using formula, we get solution

45 = \frac{1}{3} (5)(h)

cross multiplication, we get

\frac{45 x 3}{5} =h

now simplification, the height of the cone is h = 27

Put this into slope form x/2 + 2y= 6
Inga [223]

Answer:

y=-1/4x +3

Step-by-step explanation:

x/2 + 2y = 6

Subtract x/2 from both sides

2y=-x/2 +6

Simplify by dividing by 2

y=-1/4x +3

Can someone explain how to solve this and the solution? Please and thank you :)
Verizon [17]
25 > 2x + 8 - 66

first simplify all numbers

25 > 2x + (8  - 66)
25 > 2x - 58

Then add 58 to both sides

25 (+58) > 2x - 58 (+58)
83 > 2x

Finally divide 2 from both sides to isolate the x

83/2 > 2x/2

41.5 > x

hope this helps
