PleEASSSE HELP ME WITH K AND L

Mathematics

Artist 52 [7]3 years ago

K. A quadrilateral has a total angle measure of 360. We know that two of the angles are 90, so we can subtract 180 from that. We’re left with 180. So we can make it into and equation. X+2x=180. Simplify and solve, and you get that x=60.

L. Again, a quadrilateral has a total of 360. So we can subtract the right angle from that and get 270. Put it into and equation, and you get x+2x+3x=270. Simplify and solve, and you get that x=45.

The tength of a picture frame is 12 cm more than twice the width. If the perimeter is 204cm, find the
alekssr [168]

Answer:

30cm x 72 cm

Step-by-step explanation:

The perimeter is the measurements of all sides added together. Let's start by dividing the perimeter by 2, so we have the sum of the length and width. This gives us 102cm. Let's call the width <em>x</em>, and the length <em>y</em>. We know <em>y</em> is <em>x</em> times 2 plus 12. (2x + 12) So, we know [x + y = x + (2x + 12)]. So let's solve.

x + y = x + (2x + 12)

102 = x + (2x + 12)

102 = 3x + 12

102 - 12 = 3x + 12 - 12

90 = 3x

90/3 = 3x/3

30 = x

The width is 30cm.

xz_007 [3.2K]
If there are 400 silver dollars in all, and there are 275 in one bag, to find the amount in the other bag, just subtract:

400-275=125

There are 125 in the other bag.
