Ok so first you need to subtract 7.25 from both sides
-2.25=-0.5x
Then divide by -0.5
Which gives you
x=4.5
Hope this helps.
Answer:
Scale factor: 1.666
x: 10
Step-by-step explanation:
These are two similar triangles, the triangle MNO has been scaled off triangle FGH.
To calculate the scale/dilation factor, you take 2 measurements of a similar side and you calculate the ratio.
Since we have the measurements for segments GH and NO, and these are similar sides, we'll use that to calculate the scale/dilation factor of MNO over FGH.
Dilation factor is 5/3... or 1.666
if you're also looking for value of x, it would be 6 * 1.666 = 10
Answer: After 16 seconds the boats will be traveling the same speed.
Step-by-step explanation:
Given: Mike is driving a boat at 12 mph and is increasing his speed by 0.2 mph each second.
Mike's spewed after x seconds = 12 + 0.2x
Hank is driving a boat at 26.4 mph and is decreasing his speed by 0.7 mph each second.
Hank's speed after x seconds = 26.4 -0.7 x
As per given,
12 + 0.2x = 26.4 -0.7 x
Subtract 12 from both sides
0.2x= 26.4-12-0.7x
⇒ 0.2x= 14.4-0.7x
Add 0.7xn on both sides , we get
0.2x+0.7x= 14.4
⇒ 0.9x = 14.4
Multiply 10 on both sides, we get
9x=144
Divide both sides by 9 , we get x= 16
Hence, after 16 seconds the boats will be traveling the same speed.
Answer: x = 77 degrees, y = 77 degrees, z = 103 degrees
Step-by-step explanation:
Since y and 103 are essentially same side interior angles, they must add up to 180. Therefore, y = 180-103 = 77 degrees.
Opposite angles of a paralellogram are equal.
Therefore, x = y = 77 degrees and z = 103 degrees
