Answer:
Kindly check explanation
Step-by-step explanation:
Using the integer tiles :
Drawing 2 tiles each time an eagle is obtained, this gives:
-2 + - 2 + - 2 + - 2 + - 2 = - 10
Using the number line,
Each unit on the number line = - 2
Any time an eagle scored ; take a unit step to the left.
This give ls a unit step 5 times
-2 + - 2 + - 2 + - 2 + - 2 = - 10
Using direct multiplication :
-2 * 5 = - 10 as it means - 2 in 5 places ; similarly, scoring - 2 five times will give - 10
Also note :
Either - 2 * 5 or - 5 * 2 is the same due to commutativity property of multiplication
Answer: A
Step-by-step explanation: pretty sure lol
Given that in arithmetic sequence a=5 and common difference, d=4. Thus the number of terms of this sequence that must be added to attain 4185 will be found as follows:
the explicit formula for arithmetic sequence is given by:
sn=n/2(2a+(n-1)d)
where n is the number of terms:
thus plugging in the values we get:
4185=n/2(2*5+(n-1)4)
solving for n we get:
8370=(10+4n-4)
8370=(6+4n)
4n=8364
n=8364/4
n=2091
thus the number of terms will be:
2091
Answer:
$204.4
Step-by-step explanation:
The four chairs bought in June cost $35 each, all together $140. Then they bought 2 more chairs on sale for 8% off of $35 each or 92% of $35 which is $32.2 each, all together $64.4. Both buy's together would then equal $204.4
