Answer:
15s
Step-by-step explanation:
Write like so:
54m = 9s
90m = x
Cross multiply:
(90*9)=(54x)
810 = 54x
Divide both sides by 54:
810/54 = 54x/54
15 seconds = x
Answer:
Triangle PQR congruent to Triangle TSR by SAS
Step-by-step explanation:
Hope this helps
Side1 + side2 + side 3 = 84
side1 is the shortest side, and its length is x.
side2 is the middle side, and its length is x + 7
side3 is the longest side, and its length is 2x - 7
x + x + 7 + 2x - 7 = 84
4x = 84
x = 21
side1 = x = 21
side2 = x + 7 = 21 + 7 = 28
side3 = 2x - 7 = 2(21) - 7 = 42 - 7 = 35
The length of the sides are 21 m, 28 m, and 35 m.
The answer for the distibutive oneis 7(4+6)
The x coordinates are 3 and -5. They add to 3+(-5) = -2
Cut this in half to get -2/2 = -1
The x coordinate of the midpoint is x = -1
-------------------
The y coordinates are 2 and 5. They add to 2+5 = 7.
Then we cut this in half to get 7/2 = 3.5
The y coordinate of the midpoint is y = 3.5
-------------------
Overall, the midpoint is (-1, 3.5)
<h3>Answer: (-1, 3.5) which is the same as (-1, 7/2)</h3>
