First convert the fractions into inpropper fractions by takeing the denominator and multiplying it by the whole number blus the nummerator. For 3(1/2) it becomes 7/2 and for 1(1/2) it becomes 3/2. Then multiply the fractions 7/2 x 3/2 = 21/2 now make it a mixed fraction so the answer is 2(1/2)
For the one on the left they are corresponding and on the right they are vertical
Answer:
D
Step-by-step explanation:
point-slope form is y-y1=m(x-x1) . since the slope is 2 and not -2, you can automatically eliminate choices A and C. since the y-value in the point, (1,-1), is -1, you will add it to y because you are subtracting a negative. (- - = +) therefore, the final equation, in point-slope form, is y+1=2(x-1), or answer choice D.
Answer:
8x⩽112
Step-by-step explanation:
Width of the rectangle (in centimeters) = x
Therefore, the lenght of the rectable is 3x (in centimeters).
The perimeter of the rectangle (in centimeters) is : 2x+2*3x=2x+6x=8x.
The perimeter of the rectangle is at most 112cm, therefore, 8x⩽112.
