Answer: 126 5p coins
Step by step explanation:
1p+2p+5p = 630
2p= 2/5 of 630
2p= 252
1p= 2( 5p)
630 - 252 = 378
378/3= 126= 5p
378-126= 252 = 1p
252+252+126= 630
8x + 47 = 8x + 40
No solutions (the above 2 expressions cannot be equal for any value of x)
Answer:
-0.7
Step-by-step explanation:

You can choose any digits you wish for
and
but the difference must be 0.7. I chose 1.0 and 0.3.

Since 300 is 100%, you treat it as such.
300/(100/70) = 210 (rounded)
You do a similar thing for 600
1/4 of 100 is 25
100/25 = 4
600 / 4 = 150
70% of 300 is more.
The horizontal distance between the base of the skyscraper to the ship is 1145 feet.
Data;
- Angle = 45 degree
- Observation deck (adjacent) = 1145 ft
- horizontal distance (opposite) = x
<h3>Trigonometric Ratios</h3>
Using trigonometric ratios, we have the value of adjacent and angle, we can easily use tangent of the angle to find the horizontal distance

Substitute the values into the equation and solve
