Answer:
x = 27
Step-by-step explanation:
3x-4y = 65
Let y = 4
3x - 4*4 = 65
3x -16 = 65
Add 16 to each side
3x-16+16 = 65+16
3x = 81
Divide each side by 3
3x/3 = 81/3
x = 27
1-14, You're just dividing. Like #1, -14÷2=-7 (negative fourteen divided by two, equals negative seven). A positive and a positive make a positive, a negative and a positive make a negative, a negative and a negative, make a positive. The word problems your also dividing, for example, #15, -40÷4=-10. Use the numbers that are given to you.
Answer:

Step-by-step explanation:
The equation that describes the motion of the hot air ballon is:
where:
is the initial altitude
v is the rate of descend of the balloon
t is the time
The balloon starts from a height of
and has a rate of descend of
Therefore, after time
t = 12 min
Its altitude will be
Answer:
No because she added 2 instead of 2398. She thought the 2 was separate because of the comma separating the 2 thousand. She also made a mistake by thinking she could add easily by adding 2 to 2398 to make 2400.
Positive numbers are always greater than -15. Therefore, it's a greater than.
-2x = - 15
Dividing both sides by -2, we get
x = 7.5
Negative cancels on both sides, so we get a positive equation.
Positive numbers are always greater than -15. Therefore, it's a greater than.
What is greater than or less than?
- Greater than and less than are the comparison symbols.
- When the number is bigger or smaller than the other, then greater than and less than symbols are used.
- If the number is greater than the other, the greater than (>) symbol is used.
- If the number is lesser than the other, the less than the (<) symbol is used.
