Answer:
-16
Step-by-step explanation:
3*5=15
3*8=24
15-24= -9
-9-7=-16
I might not be understanding what you mean but I think it is by counting 10s. 170,180,190,200,210,220,230,240,250,260,270,280,290,300,310,320,330,410.
Answer:
Less than.
Step-by-step explanation:
I have included the explanation in bullet points so it is easier to understand.
We don't even need to solve the problem in order to find out.
- We know that any number times one is itself
- We know that any number times less than one would be less than itself.
- In order to get a product more than 6/10 we would need to multiply it by something more than 1.
- 2/3 is not more than one, which means the product would be less than 6/10
Hope this helps!

(7x -7) + (6x +6) = 90
take away the parenthesis: 7x - 7 + 6x + 6 = 90
combine like terms: 13x - 1 = 90
add 1 to both sides: 13x = 91
divide both sides by 13: <span>x = 7.
Now: substitute x = 7 into the angles: the first angle is 42 degrees, the second angle is 48 degrees</span>
First row all correct second rows all wrong and the first on of third row is correct be the last two are incorrect
