If PQ=7 and QR=10,

P=(7/Q) and R=(10/Q)

Therefore:

PR=(7/Q)(10/Q)

=(70)/Q²

Find the value of x for which ABCD must be a parallelogram.

Tems11 [23]

D. X = 8 , Y = 6
3x - 14 = x + 23x - x = 2 + 142x = 162x / 2 = 16/2x = 8
To check: 3x - 14 = x + 2 ; 3(8) - 14 = 8 + 2 ; 24 - 14 = 10 ; 10 = 10
4y - 7 = y + 114y - y = 11 + 73y = 183y / 3 = 18 / 3y = 6
To check: 4y - 7 = y + 11 ; 4(6) - 7 = 6 + 11 ; 24 - 7 = 17 ; 17 = 17
hopes it helps:)

An airliner is 9.34 feet wide. The airline wants to install 5 seats in each row. The seats are each 1.46 feet wide. Rounded to t

MatroZZZ [7]

About 2.0 feet space will be left for aisle.

Step-by-step explanation:

Width of airliner = 9.34 feet

Width on one seat = 1.46 feet

Seats to install = 5

Width of 5 seats = 5*1.46 = 7.3 feet

Space left for aisle = Width of airliner - width of 5 seats

$Space\ left\ for\ aisle=9.34-7.3\\Space\ left\ for\ aisle=2.04\ feet$

Rounding off to nearest 10th

Space left for aisle = 2.0 feet

About 2.0 feet space will be left for aisle.

Solve the inequality<br> -2(y+5)+22>12-2y

zhannawk [14.2K]

Answer:

There are no solutions

Step-by-step explanation:

Always remember to simplify both sides of the inequality.

$-2y+12>-2y+12$

Add 2y to both sides.

$-2y+12+2y>-2y+12+2y\\12>12$

Subtract 12 from both sides.

$12-12>12-12\\0>0$
