Dmitry_Shevchenko [17]

Answer:

7x + 18 + 5x - 6 = 180 \\ 12x + 12 = 180 \\ 12x = 180 - 12 = 168 \\ x = 168 \div 12 =14 \\ 3y + 11 = 7x + 18 = 7 \times 14 + 18 \\ 3y + 11 = 98 + 18 = 116 \\ 3y = 116 - 11 = 105 \\ y = 105 \div 3 = 35

Find the perimeter of the figure. Round all figures to the nearest hundredths place. Isosceles trapezoid
zhannawk [14.2K]

Answer:

d. 92.84

Step-by-step explanation:

The top edge overhangs the bottom edge by (39 -27)/2 = 6 ft on both ends. This makes the slant side have length  

.. √((6 ft)^2 +(12 ft)^2) = 6√5 ft

Then the perimeter is

.. (39 +6√5 +27 +6√5) ft = 66 +12√5 ft

= 92.83 ft

Lubov Fominskaja [6]

Answer:

$5.5

Step-by-step explanation:

6 * N (notebook) + 3 * P (pen) = 27

n = 1.5 +P

6 * (1.5 + P) + 3 * P = 27

9 +6p +3p = 27

9p = 18

p (pen): $2

N (notebook): $3.5

combined cost of 1 pen and 1 notebook: $2 + $ 3.5 = $ 5.5
