Answer:
7/12 are left.
Step-by-step explanation:
Convert 1/3 and 1/4 so the have a common denominator. The common denominator is 12 so 1/3 turns into 4/12 and 1/4 turns into 3/12. 3/12 plus 4/12 equals 7/12.
Hope this helps. Hoping for brainliest
Answer:
7. 69
Step-by-step explanation:
6x+3(x-7) when x=10
6(10)+3(10)-21
60+30-21
90-21
69
If the carpet sells for 4 per sq ft, and u paid 748...then u got (748/4) = 187 sq ft. of carpet
A = L * W
A = 187
L = 17
187 = 17W
187/17 = W
11 = W <=== the width of the room is 11 ft
Answer: (8,1)
Step-by-step explanation:
The line that connects (-4,5) and (2,3) has a slope of (-2/6) or -1/3. The y-intercept is calculated from one of the points: 3 = -(1/3)*(2) + b
b = 3 2/3
The equation for the line is y = -(1/3)x + 3 2/3
The reflection covers a distance of x of (2 - (-4)) = 6. Add 6 to the x value of (2,3) and calculate the resulting y. (8,y): y = -(1/3)(8) + 3 2/3, y = -8/3 + 11/3 = 3/3 or 1
The point is (8,1)
The series is an arithmetic series with first term -10 and common difference (-2-(-10))=8. The general term a_n can be written as
a_n = -10 + 8(n-1)
or
a_n = -18+8n
The last term corresponds to
110 = -18+8n
128 = 8n
16 = n
So, the summation can be written as
