the equation would be x-12=20.
the solution would be x=8.
Answer:
Multiply the ones. 9 times 83 is 747. Multiply the tens. 30 times 83 is 2,490. Add the products to get 3,237.
The rest of the question:
Which gives the correct order of steps needed to multiply the problem below? "83x39
"
The steps to multiply 83x39
1) multiply the ones 9 times 83 = 9 times 3 + 9 times 80 = 27 + 720 = 747
2) multiply the tens 30 times 83 = 30 times 3 + 30 times 80 = 90 + 2400 = 2490
3) add 747 and 2490 = 747 + 2490 = 3,237
According to the previous steps, the answer is option 3
Multiply the ones. 9 times 83 is 747. Multiply the tens. 30 times 83 is 2,490. Add the products to get 3,237.
Perimeter = 18 miles
Perimeter = 2a + 2b
2a + 2b = 18
a = ?
b = 7
18 = 2a + 2*7
18 = 2a + 14
2a = 18 - 14
2a = 4
a = 2
Area = a * b
Area = 2 * 7 = 14 miles2
Answer:
BD = 3 units
Step-by-step explanation:
Since, AD is an angle bisector of ∠BAC,
m∠BAD = m∠CAD = 20°
CD = 3 units
In ΔACD and ΔABD,
m∠BAD = m∠CAD = 20° (Given)
AD ≅ AD [Reflexive property]
Therefore, by H-A property of congruence both the triangles will be congruent.
And by CPCTC,
CD ≅ BD = 3 units
