Answer:
x = -5 y = -3
Step-by-step explanation:
-3x + 2y = 9
multiply the 2nd equation by 3 to set it up for elimination
3(x - 3y)= 3(4)
3x-9y = 12
so now combine both to add
-3x + 2y = 9
3x - 9y = 12
Adding both gives you
-7y = 21
divide both by -7 and you get
y = -3
and you substitute y back into equation to get x
x - 3 (-3) = 4 gives you
x + 9 = 4
x = 4 - 9
x = -5
Biker's rate is:
v = 5/0.5
v = 10 ft per sec
t = 1 min = 60 sec
d = the distance the biker travels in 1 minute
v = d/t
d = v*t
d = 10*60
d = 600 ft
The biker travels 600 feet in 1 minute
Answer:
Cube has larger volume than cylinder.
Step-by-step explanation:
Given:
Side of a cube = 7 cm
Radius of a cylinder (r) = 5 cm
Height of a (h) = 4 cm
Find:
Larger volume = ?
Computation:
Volume of cube = Side³
Volume of cube = 7³
Volume of cube = 343 cm³
Cube has larger volume than cylinder.
Answer:20cm
Step-by-step explanation:
2/3×30/1=(2×30)/(3×1)=60/3=20cm
