E=elliptical
T= treadmill
12E+10T=676
also, she worked out one hour
E+T=60
E=60-T   we substitute now
12(60-T)+10T=676
720-12T+10T=676
720-2T=676  substract 720 from both sides
-2T=-44 now divide by (-2)
T=22
if T=22 E=60-22=38
she spends 38 min on the elliptical

sasho [114]

Answer:

x-3

Step-by-step explanation:

f(x) = 3x - 2

g(x) = 2x + 1,

(f- g)(x) =  3x - 2  - ( 2x+1)

Distribute

            = 3x -2 -2x-1

Combine like terms

The coordinates of LMN are L (4,5), M (5,-2), and N (0,0). If the triangle is rotated 270° about point N, what are the coordinat
tester [92]

Answer: (-2,-5)

Step-by-step explanation:

The rotation rule for rotating a figure about 270^{\circ} is given by :-

(x,y)\to (y,-x) , where (x,y) is the coordinates for pre-image and (y,-x) is the coordinates for image.       (1)

Given : The coordinates of LMN are L (4,5), M (5,-2), and N (0,0).

If the triangle is rotated 270° about point N

Then, the coordinates of M , will be :

(5,-2)\to (-2,-5)   (Using the rule described in (1))

Hence, the coordinates of M after rotated 270° about point N=(-2,-5).
