Answer:

106

Step-by-step explanation:

Let's try guessing...

45+45=90\\30+30+30=90\\10+20+30+30=90

All the units place has to be 4, if it is higher than 4 then the answer will not be 90 (the sum of the four rounded numbers).

14 + 24 + 34 + 34= 106

Please help me i don’t understand
Bond [772]

9514 1404 393

Answer:

  2. chord theorem; t = 10.5

  3. chord theorem; x = 5

Step-by-step explanation:

For both of these problems, the relevant theorem is the "intersecting chord theorem", also referred to as the "chord theorem." It tells you the product of the lengths of the parts of one chord is equal to the product of the lengths of the parts of the other chord.

2. 20t = 10·21

  t = 210/20 . . . . divide by 20

  t = 10.5 . . . . . . . simplify

__

3. 10(x +4) = 15(x +1)

  10x +40 = 15x +15 . . . . . eliminate parentheses

  25 = 5x . . . . . . . . . . . . . subtract 10x+15

  5 = x . . . . . . . divide by 5

12x +7 < −11 OR 5x −8 > 40
r-ruslan [8.4K]

For this case we must resolve each of the inequalities and find the solution set.

Inequality 1:

12x + 7

We subtract 7 from both sides of the inequality:

12x

We divide between 12 on both sides of the inequality:

x

Thus, the solution is given by all values of x less than- \frac {3} {2}.

Inequality 2:

5x-8> 40

We add 8 to both sides of the inequality:

5x> 40 + 8\\5x> 48

We divide between 5 on both sides of the inequality:

x> \frac {48} {5}

Thus, the solution is given by all values of x greater than\frac {48} {5}.

The solution set is given by:

(-∞, - \frac {3} {2}) U (\frac {48} {5},∞)

Answer:

(-∞, - \frac {3} {2}) U (\frac {48} {5},∞)
