Step - by - step - explanation
So first find out the pattern. As you can see it just minuses 2 each time. So first
18, 16, 14, 12 (then minus another 2) equals 10, 8, 6, 4, 2.
So 2 is the ninth of the pattern, so 2 will be your answer.
Hope this helps.
Answer:
D
Step-by-step explanation:
a - 3 = 7 ( add 3 to both sides )
a - 3 + 3 = 7 + 3 , that is
a = 10
Answer:
Width is 18 inches
Perimeter is 99 inches
Area is 567 square inches
Step-by-step explanation:
The ratio of width to length is 4 : 7
The length is 31.5 inches
The width = (31.5 ×4) ÷ 7 = 18 inches
Perimeter = 2(length + width)
Perimeter = 2(31.5 + 18) inches = 99 inches
Area =length × width
Area = 31.5 inches × 18 inches = 576 square inches.
Answer:
x+2x-3
because nates car is x and mayas is 2x-3
The value of the angles should be. (x-40°). , (x-20°), (½x-10°) , not (x-40°) + (x-20°)+(½x-10°)
Sum of all the interior angles of a triangle is 180°.
So a equation can be made by the given data,
(x-40°) + (x-20°) + (½ x-10°) = 180°
x-40°+x-20°+½x-10° = 180°
2x+½x -60°-10° = 180°
5/2 x - 70° = 180°
5/2 x = 180° + 70°
5/2 x = 250°
x = 250° × 2/5
x = 50° × 2
x = 100°
So the angles are
x-40° = 100°-40° = 60°
x-20° = 100°–20° = 80°
½x-10° = ½(100)° - 10° = 50° -10° = 40°
The answer can be checked by putting the values of the angle we got in the second statement i.e. Sum of all the interior angles of a triangle is 180°.
60° + 80° + 40° = 100° + 80° = 180°
