Hi. Here it is!
I hope this help...
—> And the answer is letter A
Answer:
- 28
Step-by-step explanation:
4(5x + 3y - 7) ← multiply each term in the parenthesis by 4
= 20x + 12y - 28
Answer:
240
Step-by-step explanation:
remember that to get from positive to negative you have to go from positive to 0 then to negative .
however the easiest way of solving this is
add both the values , ignore the sign
130 + 110
the difference in the temperature is :
= 240 degrees
Question number 10 is the same as the previous questions add them up and make them equal to 180 degrees, and then solve for the x variable.
For the second part of the question, simply plug in the value of x for each expression for R and S.
The answer is C.
If Sergio is 'S' years old, and you want to know how old he'll be in 7 years, add 7 years to his age.
So: s + 7
Hope this helps!
