Answer:
-16x-28
Step-by-step explanation:
Break it into little pieces; start with distributing the -7:
-7(5+x)
-35-7x
Now add the rest of the problem: 7-35-7x-9x
Combine like terms: 7-35 7x-9x
7-35=-28 7x-9x=-16x
Rearrange so the coefficient and variable are upfront, giving you:
-16x-28
Santosh's cousin is 15 years old because 49-4=45. Divide 45 by 3 and the quotient is 15. To check: 15 times 3= 45. Add 4 and the sum is 49.
Answer:
It is 27.4
Step-by-step explanation:
First you need to find the area of the three rectangle.
Area=base*high
You do 4*2 for about 3 times
Which is 8 for 4*2
Then you multiply it 3 more time and get 24.
After that you add 24+1.7+1.7 and get 27.4
