2x+3y=13 4x-y=-2 Thanks

Mathematics
1 answer:
sergejj [24]3 years ago
5 0

Answer:

2x+3y=13 ------(1)

4x-y=-2 -----(2)

Multiply (1) by 2,

=> 4x + 6y = 26. ---(3)

Subtract (2) from (3),

4x - 4x + 6y + y= 26 + 2

7y = 28

y = 4

x = (13-3(4))/2

x = 1/2.

HOPE IT HELPS!!!

Compare fraction 2over 3 and 7 over 8 which is greater
Paul [167]
If you use a calculator to find the exact decimal of these fractions, you can easily find this out.

2/3 as a decimal equals:  0.6666 (repeating sixes)

7/8 as a decimal equals:  0.875

0.875 > 0.666

7/8 > 2/3

7 over 8 is greater!  Hope this helps! :)

An h = 135-ft tower is located on the side of a mountain that is inclined 32° to the horizontal. A guy wire is to be attached to
Vikentia [17]

Answer:

171 foot

Step-by-step explanation:

We are given that

Height of tower=135 ft

AC=55 ft

Let x be the length of shortest length of wire.

The angle of inclination of mountain with horizontal =32^{\circ}

The angle between sides AB and BC=90+32=122^{\circ}

Exterior angle is equal to sum interior angles of a triangle on the opposite sides .

We have to find the value of x.

We know that law of cosine

c=\sqrt{a^2+b^2-2ab cos\theta}

Substitute the values in the given formula we get

x=\sqrt{(135)^2+(55)^2-2(135)(55)cos 122}

x=170.64 ft

Hence, the length of wire needed=171 foot
