I encountered this question before. It lacks pertinent information. 

Amira is painting a rectangular banner 2 ¼ yards wide on a wall in the cafeteria. The banner will have a blue background. Amira has enough blue paint to cover the 1 ½ square yards of wall.

a)      Find the height of the banner if Amira uses all of the blue paint. Show work.

b)      The school colors are blue and yellow, so if Amira wants to add yellow rectangles on the left and right sides of the blue rectangle. The yellow rectangles will each be 3/4 yard wide and the same height as the blue rectangle. What will be the total area of the two yellow rectangles?

 

Area of a rectangle = length * width

Area using the blue paint = 1 ½ square yards.

Height = 1 ½ square yards / 2 ¼ yards or  1.5 sq. yds / 2.25 yd = 0.666 yd or 2/3 yd

1 Yellow rectangle: width = ¾ yards ; length = 2/3 yards

Area of yellow rectangle = ¾ yds * 2/3 yds = 6/12 or ½ square yards

Area of the 2 yellow rectangles = ½ square yard * 2 = 1 square yard.

Hello Guys, I really need help with these questions. Here they are.
Slav-nsk [51]

Answer:

See below.

Step-by-step explanation:

It can really help to think when you see |expression| that it means the distance from expression to zero.

(a)  |x| < 7  means the distance from  x  to 0 is less than 7.  That puts  x  between -7 and 7.  The solution set is  -7 < x < 7.

(b)  |x + 3| < 9 means that the distance from x + 3 to 0 is less than 9.  That puts x + 3 between -9 and 9:

-9 < x + 3 < 9   Now subtract 3 from all three parts.

-12 < x < 6

(c)  |y - 8| > 11 means that the distance from y - 8 to 0 is more than 11 units.  That puts  y - 8 in one of two places:  left of -11 or right of 11.

y-8 < -11 \text{ or } y-8 > 11\\\\y < -3 \text{ or } y > 19

(g)  |3x-1| \ge 18 means that the distance from 3x - 1 to 0 is more than (or equal to)  18.  Another way to say it is, 3x - 1 is farther from 0 than 18 units.  That puts  3x - 1 in one of two places:  to the left of -18 or to the right of 18.

3x-1  \le -18 \text{ or } 3x-1 \ge 18\\\\3x \le -17 \text{ or } 3x \ge 19\\\\x \le -\frac{17}{3} \text{ or } x \ge \frac{19}{3}

|4y+3| \le 13  means that 4y + 3 is closer to 0 than 13;  it is between -13 and 13.

-13 \le 4y+3 \le 13\\\\-16 \le 4y \le 10\\\\-4 \le y \le \frac{5}{2}

(That last fraction is 10/4 simplified.)

Solve the system of equations using any appropriate method: 5x + 2y = -4 and -x + 2y = 8
Maru [420]

Answer:

A

Step-by-step explanation:

-x + 2y = 8

5x + 2y = -4

+ x. -2y. -8

6x = -12

÷6. ÷6

x = -2

5(-2) + 2y = -4

-10 + 2y = -4

+10. +10

2y = 6

÷2. ÷2

y = 3

frosja888 [35]

Answer:

$204.4

Step-by-step explanation:

The four chairs bought in June cost $35 each, all together $140. Then they bought 2 more chairs on sale for 8% off of $35 each or 92% of $35 which is $32.2 each, all together $64.4. Both buy's together would then equal $204.4
