The total temperature of the magnesium sample is its original temperature plus the temperature increase which is dependent on time. This total should exceed 650 degrees. Thus, the inequality that best describes the condition is,
255 + 10m ≥ 650
m ≥ 39.5
The answer is letter b.
We have such equation
6x+3=4x+9 /-4x subtract 4x both sides
6x-4x+3=4x-4x+9
2x+3=9 /-3 subtract 3 both sides
2x=6 /:2 divide both sides by 2
x=3 - its result
Answer:
The way a proportion is set is as follows;

The Distance from Rio de Janeiro and San Jose Costa Rica is then found as 800 miles
Step-by-step explanation:
The dimension of the distance between Rio de Janeiro and San Jose Costa Rica = 4 inches
The map scale = 1 inch to 200 miles
To figure out how many miles it is or the actual distance from Rio de Janeiro and San Jose Costa Rica, we have;

Therefore, we have;
(4 inches × 200 miles)/(1 inche) = Distance from Rio de Janeiro and San Jose Costa Rica
Which gives;
Distance from Rio de Janeiro and San Jose Costa Rica = 800 miles.
The answer is 600,000+ 40,000+700+30+9.
May you give me the branliest answer?
