X = longer piece, y = shorter piece
x + y = 21
x = y + 13
y + 13 + y = 21
2y + 13 = 21
2y = 21 - 13
2y = 8
y = 8/2
y = 4 <=== shorter piece is 4 ft
x = y + 13
x = 4 + 13
x = 17 <== longer piece is 17 ft
Answer:6
Step-by-step explanation:
Answer:
B. 36 square meters
Step-by-step explanation:
Find the areas of the rectangle and triangle. Then, subtract the area of the triangle from the area of the rectangle to get the area of only the figure.
rectangle A = 8(6) = 48 square meters
triangle A = 1/2(8)(3) = 12 square meters
48 - 12 = 36 square meters
Are you sure you cancel out as seen on your paper? Because I would have said 2 4/7 was answer which is not the same as answer when you canceled out
Answer:
- diagram is below
- 6, 11, 16, 21
- s[n] = s[n-1] +5
- 26, 31, 36
Step-by-step explanation:
a) See below for the next diagram in sequence.
__
b) The numbers of straws in each diagram are ...
6, 11, 16, 21, ...
__
c) Each term is 5 more than the previous one, so the recursive rule for the number of straws is ...
s[1] = 6
s[n] = s[n-1] +5
__
d) The next three terms of the sequence are ...
..., 26, 31, 36, ...
