Base your answer to the following question on the diagram shown and the given information

erik [133]

Answer:

29°

Step-by-step explanation:

∠1 ≅ ∠8

3x+25 = 4x -17

42 = x . . . . . . . . . . add 17-3x

Now, we can find the measure of ∠1:

m∠1 = 3(42) +25 = 151

Angle 2 is the supplement to this, so has measure ...

m∠2 = 180° -151° = 29°

Write the numbers 23,643 and 23,987 so they line up by place value. Explain how to line them up

weqwewe [10]

Consider the numbers 23,643 and 23,987.

Since both the given numbers have same digits at ten thousands and thousands place.

So, we can'not compare the numbers on the basis of ten thousands and thousands digit.

So, let us consider the number 23,643

Consider the place value of digit at the hundreds place. Since, the digit at hundreds place = 6.

The place value of 6 = 600

Now, let us consider the number 23,987

Consider the place value of digit at the hundreds place. Since, the digit at hundreds place = 9.

Te place value of 9 = 900

Since, 900 > 600

So, 23,643 > 23,987

Therefore, the number 23,987 is greater than the number 23,643.

What is the largest digit N for which 2345N is divisible by 6?

kotegsom [21]

Consider this option (this is not the only way):
1. according to the condition 2345N is divisible by 6, it means, that N is even number (0;2;4;6 or 8).
2. 6=3*2, then the number 2345N is divisible by 3 also. It means, that the number (2+3+4+5+N)=(14+N) is divisible by 3, where N={0|2|4|6|8}.
3. using items 1 and 2:
(14+4)=18; only 18 is divided by 3, it means that N=4.

answer: 4.

Note also, that only 23451; 23454 and 23457 are divided by 3. Only 23454 is divided by 6 (23454/6=3909).
