If we double all the lengths, the area increase by a factor of 2².
The dragonfly traveled a distance of 87.5 miles at a rate of 35 miles per hour.
Explanation:
Distance traveled by butterfly at the rate of 34 miles per hour in 2.5 hours
=35 mi/hr × 2.5 hour
=<span><span>35mi</span><span>hour</span></span> ×2.5 <span>hour</span>
=<span>35mi⋅<span>2.51</span>⋅<span>1010</span></span>
=<span>35mi⋅<span>2510</span></span>
=<span>35mi⋅<span>52</span></span>
=<span>175m<span>i2</span></span>
=<span>87.5mi</span>
∴ It would travel a distance of 87.5 miles.
Here mi represents miles.
Answer:
x=1 y = -1/2
(1,-1/2)
Step-by-step explanation:
7x-2y=8
5x+2y=4
I would use elimination since we have 2y in one equation and -2y in the other
7x-2y=8
5x+2y=4
--------------------
12x = 12
Divide each side by 12
12x/12 = 12/12
x =1
The substitute back into equation 2
5(1) +2y = 4
5 +2y = 4
Subtract 5
5-5+2y = 4-5
2y = -1
Divide by 2
2y/2 = -1/2
y = -1/2
So you subtract, 27-22. 27-22 is equal to 5. So, John will buy 5 kinds of T- Shirts.
