Answer:
4.27985 and 14.72015
Step-by-step explanation:
4.27985 x 14.72015 = 63
4.27985 + 14.72015 = 19
Answer:
multiply 10 with the value given for x and add 2 to the result
He bought 4 cards for $4 so that's 16 he put 20 in each that's 80 and 70 x 4 is 1,400 so all of that in total would be 1,436, correct me if I'm wrong, and if you're too lazy to read than, the answer is 1,436
Answer:
3135
Step-by-step explanation:
Givens
a1 = 6
Use t4 - t3 to get d
t4 = 27
t3 = 20
Step One
Find a1 and d
a1 = 6
d = t4 - t3
d = 27 - 20
d = 7
Step Two
Find the 30th Term
tn= a1 + (n -1 )*d
t30 = 6 + (30 - 1) * 7
t30 = 6 + 29*7
t30 = 6 + 203
t30 = 209
Step Three
Find the sum using Sum = (a + t30)*n/2
n = 30 given
a1 = 6 given
t30 = 209 calculated from step 2
Sum = (a1 + t30)*n/2 Substitute
Sum = (6+ 209)*30/2 Combine like terms and divide by 2
sum = 215 * 15 Multiply
Sum = 3135 Answer
