Answer:
4,296
Step-by-step explanation:
because 4 thousands = 4,000, 9 hundreds = 900, 2 tens = 20 and 6 ones= 6, 400 + 900 + 20 + 6 = 4,920
Answer:
100
Step-by-step explanation:
add all the number together 3 + 4 + 2 +1=10
250/10=25
then times 25 with the 4 number at the top
25 times 4 =100
so there is 100 blue pencils
Total no. of students - 140 students
Total no. of students from all schools= 140+70+35+105=350
school A= 140÷350×100=40./. (multiplying by 100 because it's the total percentage )
School B = 70÷350×100=20./.
School C = 105÷350×100=30./.
School D = 105÷350×100= 10./.
Consisting all the schools percentage it gives 100./.
Hope this helps
Simplify:
A(n) = -6 + (n - 1)(6) = -6 + (n)(6) + (-1)(6) = -6 + 6n - 6 = 6n - 12
Put n = 1, n = 4 and n = 10 to the expression:
A(1) = 6(1) - 12 = 6 - 12 = -6
A(4) = 6(4) - 12 = 24 - 12 = 12
A(10) = 6(10) - 12 = 60 - 12 = 48
<h3>Answer:</h3><h3>first term = -6, fourth term = 12 and tenth term = 48.</h3><h3>-6, 12, 48</h3>
