Let the required number is 2x ,
According to the condition,
➡ 10 times the sum of half of 2x and 6 = 8

Therefore the value of x is -5.2
And, required number is -5.2
Step-by-step explanation:
1st digit is 1 number (1)
2nd digit is (3,4,5) so it's 3 numbers
third digit is (6,7,8,9) is it's 4 numbers
last 7 digits is 10 (0,1,2,3,4,5,6,7,8,9)
multiply
1*3*4*10=120
so answer is 120 phone numbers
Answer:
14
Step-by-step explanation:
(9x + 10)° = 136°
9x + 10 = 136
9x = 126
x = 14
Should be 37 if you use Pythagorean theorem!
Answer: 24 fliers
Step-by-step explanation:
he had 80 to begin with so last week if he posted 1/4 of them he would have 3/4 left and
3/4 * 80 = 60
and then if he posts 3/5 of the 60 remaining fliers he would have 2/5 left over and
2/5 * 60 = 24
so your answer is 24 fliers
