Solution
The 1st term = -3
15th term = 53
15th term = a + d(n-1)
53 = -3 + d(15- 1) [Here n = 15)
53 + 3 = d(14)
14d = 56
d = 4
The common difference is 4.
Answer:
10 times greater
Step-by-step explanation:
When you write these as numbers, you get:
800,000,000 (8 hundred million place)
80,000,000 (8 ten million place)
Then divide the greater number by the less number:
800,000,000/800,000,00
make this easier by eliminating 0's:
80<u>0,000,000</u>/8<u>0,000,000</u>
80/8
10
10 times greater is your answer
Hope this helps!
Answer:
See explanation
Step-by-step explanation:
Consider triangles ABC and DEC. In these triangles,
- given
- given;
as vertical angles.
So,
by SAS postulate (two sides and angle between these sides of one triangle are congruent to two sides and angle between these sides of another triangle, so triangles are congruent).
Congruent triangles have congruent corresponding parts, hence,

The answer is B, 8. 2 exponent 3 is 8 because to find an exponent multiply the base by itself with the exponent number: 2*2*2 which is 8.
