Answer:
x = 31
Step-by-step explanation:
The sum of angles in a triangle is 180°.
98° +51° +x° = 180°
x° = 31° . . . . . . . . . . . . subtract 149°
x = 31
3x-8 = 8x+4
subtract 3x from each side
-8 = 5x+4
subtract 4 from each side
-12 = 5x
divide -12 by 5 to get x
x = -12/5 = -2.4
Answer:
its A.
Step-by-step explanation:
Answer:
72 Keychains
Step-by-step explanation:
120 feet = $3.25
divide 120 by 3.25 to find how much string can be bought with $1. The result is 36.923. Then multiply that number by the number of dollars allotted to buying string. 8*36.923= 295.384. This is the total number of feet of string they have. They use 1 foot for each key chain so they can make 295 keychains based on how much string they have.
35 beads = $2.59
Divide 35 by 2.59 to find how many beads can be bought with $1. The result is 13.514. Then multiply that number by the number of dollars allotted to buying beads. This comes out to 364.878. This means She can buy 364 beads. Each Key chain needs 5 beads so divide 364/5 getting a total of 72 keychains.
Since there aren't enough beads to make any more than 72 keychains, they can make a total of 72 keychains (even though there is extra string)
A regular hexagon can be split into 6 congruent triangles
The area of one triangle = 1/2 * 8 * 7 = 28 ft^2
Area of the deck 6*28 = 168 ft^2 answer
