Step-by-step explanation:
Answer:
32
Step-by-step explanation:
As per what is given
- the product of 4 and a number decreased by 7 (4 times that number let us call it x, minus 7)
- equals 100, the equation formed equals 100
Form an equation;
4(x - 7) = 100
Solve using inverse operations;
4(x - 7) = 100
/4 /4
x - 7 = 25
+7 +7
x = 32
Answer:
1. The angles of a triangle added up all together is 180. So, we can solve a as an equation!
36+57+a=180.
From this, we can figure out a:
a=87
2. The same goes for this one, just a bit different. We write our equation like this:
3x+90=180
we solve this:
3x=90
we divide both sides by 3 and get:
x=30
Wheels are 1.25 inches in diameter.
fastest speed is 3ft/sec.
maximum distance to travel is 16 x (18 cm)
1. convert the dimensions for the wheel and maximum distance to feet.
wheel diameter in feet: = 1.25/12 ft
maximum distance in feet: 16*18 = 288 cm
max d = 288/(2.54*12) = 24/2.54 ft
