Answer:
both
Step-by-step explanation:
get a line graph
They are equivalent. combine like terms on the first one and 9x-4x+25 can be simplified to 5x+25.
Distribute so times what's outside by what's inside so 4×2x=8x and 4×7=28 then get x by itself by dividing on both sides 28÷8=3.5 your answer is x=3.5
0.5 will be rounded to 1.0
1.2 will be rounded to 1.0
1.7 will be rounded to 2.0
3.4 will be rounded to 3.0
82.2
Add all of them up and then divide by 10.
