Check the consistency of 2x-3y=7 and x-2y+1=0

Furkat [3]

Answer:

x = 17, y = 9

or as an ordered pair, (17, 9).

The equations are consistent.

Step-by-step explanation:

2x - 3y = 7

x - 2y = -1 Multiply this equation by -2:

-2x + 4y = 2 Add this to the first equation:

y = 9.

Plug y = 9 into the second equation:

x - 2*9 = -1

x = -1 + 18 = 17.

Write this fraction as a sum or difference. 17. 9p-63

Alex787 [66]

P=7 because when you do bring 63 on the other side it'll be 9p=63 and after that divide both sides by 9 and you'll have p=7

Irina-Kira [14]

Answer:

73 feet.

Step-by-step explanation:

Given:

A rope from the top of a pole is anchored to the ground which is 55 ft away from the base of the pole.

The pole is 48 ft tall.

Question asked:

What is the length of the rope?

Solution:

Here we found that a right angle triangle is formed in which base and height is given as shown in the figure, we have to find the longest side of the triangle,

Base = 55 feet

Height = 48 feet

Length of the rope = ?

By Pythagoras theorem:

Square of longest side = Square of base + Square of height

$(Longest\ side)^{2} =$ $55^{2} +48^{2}$

$(Longest\ side)^{2} =$ $3025+2304$

$(Longest\ side)^{2} =$ $5329$

Taking root both side

$\sqrt[2]{(Longest\ side)^{2} } =\sqrt[2]{5329}$

$Longest\ side =$ $73$

Thus, length of the rope is 73 feet.
