The number is 63, so the quotient is 2.
Two digit numbers divisible by 21:
21, 42, 63, 84
21: 2-1 = 1 * 3.5 = 3.5
3.5*2*1 = 7 but 7 does not equal 21
42: 4-2 = 2 * 3.5 = 7
3.5*4*2 = 28 does not equal 42
63: 6-3 = 3*3.5 = 13.5
3.5*6*3 = 63 :)
Check:
21(6-3)=21(3)= 63 :)
3.5(6)(3) = 21(3) = 63 :)
63: 6/3 = 2
Answer
295.4426m²
Step-by-step explanation:
97m÷2=48.5
<h3>a=πr²</h3><h3>a=(π×48.5)²</h3><h3>a= (3.14×94.09)</h3><h3>a= 295.4426m²</h3>
Answer/Step-by-step explanation:
5. 21x + 4 = 22x - 2 (corresponding angles)
Collect like terms
21x - 22x = -4 - 2
-x = -6
divide both sides by -1
x = 6
6. (x + 72) + (x + 132) = 180 (linear pair)
x + 72 + x + 132 = 180
Add like terms
2x + 204 = 180
2x = 180 - 204
2x = -24
x = -12
7. 90 = 22x + 2 (vertical angles)
90 - 2 = 22x
88 = 22x
Divide both sides by 22
4 = x
x = 4
8. 12x + 10 = 13x + 3 (vertical angles)
Collect like terms
12x - 13x = -10 + 3
-x = -7
Divide both sides by -1
x = 7
9. 17x = 16x + 5 (alternate exterior angles)
17x - 16x = 5
x = 5
✔️17x
Plug in the value of x
17(5) = 85°
10. 21x - 6 = 20x (corresponding angles)
Add like terms
21x - 20x = 6
x = 6
✔️20x
20(6) = 120°
Answer is 80cm because you do length x width x height and get the answer
