Answer:
45
Step-by-step explanation:
Simply start by listing out the numbers from smallest to largest.
We start out with the smallest number following this information being the number 10. The next are 21 and 20. The next are 32, 31, and 30. We can start to see a pattern. If the ten's digit is n, then there are n numbers within that ten-group that have a greater 10's digit than unit's digit. The largest ten-group (90 to 98) has 9 integers following the rules established. Thus, the number of 2-digit integers that have ten's digits greater than units digit is 1+2+3+...+9=45
Answer: distributing
2(6x + 6) <em>is</em> 12x + 12
16x - 8 <em>is</em> 8(2x - 1)
3(x - 2) <em>is</em> 3x - 6
3(4x + 4) <em>is</em> 12x + 12
2x + 6 <em>is</em> 2(x + 3)
4(x + 3)<em> is</em> 12x + 12
Step-by-step explanation:
Distribute the number in front of the parenthesis to the numbers inside the parenthesis .
for example: 3(x-2)
3 times x = 3x
3 times -2= -6
answer: 3x - 6
