Answer:

x = 44.5

Step-by-step explanation:

The angles defined by x will be supplementary when the lines m and n are parallel.

(x +4) +(3x -2) = 180

4x +2 = 180

4x = 178

x = 44.5 . . . . will make m and n parallel

the rectangle shown has a perimeter of 56 cm and the given area. it's length is 8 more than three times it's width. write and so

stiv31 [10]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's solve ~

Assume width of rectangle be " x ", length = 3×width + 8 = 3x + 8 ~

Now, Perimeter of rectangle is :

$\qquad \sf \dashrightarrow \:2(l + w) = 56$

$\qquad \sf \dashrightarrow \:2(3x + 8 + x) = 56$

$\qquad \sf \dashrightarrow \:2(4x + 8) = 56$

$\qquad \sf \dashrightarrow \:4x + 8 = 56 \div 2$

$\qquad \sf \dashrightarrow \:4x + 8 = 28$

$\qquad \sf \dashrightarrow \:4x = 28 - 8$

$\qquad \sf \dashrightarrow \:x = 20\div 4$

$\qquad \sf \dashrightarrow \:x =5 \: cm$

Hence, width = x = 5 cm

$\qquad \sf \dashrightarrow \:l = 3w + 8$

$\qquad \sf \dashrightarrow \:l = 3(5)+ 8$

$\qquad \sf \dashrightarrow \:l = 15+ 8$

$\qquad \sf \dashrightarrow \:l =23 \:cm$

And, length = 26 cm

Reza is ordering pizza and chicken fingers for a birthday party. Each pizza costs $15 and each dozen of chicken fingers costs $1

Arlecino [84]

Answer:

x+y $\geq$ 5

Step-by-step explanation:

Pizza: $15

Chicken Fingers (Dozen): $10

5x= $75

The answer should be 15x + 10y ≤ 120

Since the pizza is x and chicken fingers is y then this should be the answer.
