Answer by JKismyhusbandbae:
x - 10 ≤ 19
x - 10 + 10 ≤ 19 + 10
x ≤ 29
x - 10 ≥ - 19
x - 10 + 10 ≥ - 19 + 10
x ≥ - 9
Answer: - 9 ≤ x ≤ 29
Answer: put 3 in the blank
Explanation:
![3x-7=3x+12\,\,\,|-3x\\-7 = 12](https://tex.z-dn.net/?f=3x-7%3D3x%2B12%5C%2C%5C%2C%5C%2C%7C-3x%5C%5C-7%20%3D%2012)
The last row shows that this equation will never be true no matter what value of x. This shows that setting the coefficient of x to 3 makes the equation have no solutions.
Answer: ![1,124\frac{11}{13}\ minutes](https://tex.z-dn.net/?f=1%2C124%5Cfrac%7B11%7D%7B13%7D%5C%20minutes)
Step-by-step explanation:
Let be "x" the time in minutes that will take him to mow the entire park.
You know that he can mow 13 square feet in 1 minute and he has to mow 14,623 square feet.
Then, you can write the following proportion:
![\frac{1}{13}=\frac{x}{14,623}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B13%7D%3D%5Cfrac%7Bx%7D%7B14%2C623%7D)
Solving for "x", you get:
![x=\frac{14,623}{13}\ min](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B14%2C623%7D%7B13%7D%5C%20min)
To write that improper fraction as a mixed number:
- The quotient when you divide the numerator by the denominator of the fraction obtained, is
(This will be the whole number).
- The remainder of that division is
(This will be the numerator of the fraction).
- The denominator does not change.
Then:
![x=1,124\frac{11}{13}\ min](https://tex.z-dn.net/?f=x%3D1%2C124%5Cfrac%7B11%7D%7B13%7D%5C%20min)
The answer is C
I’m 100% sure
Explanation:
If 3 is 56.5, then 4 would be:
180-56.5= 123.5
Since 3 and 4 are parallel to 7 and 8, they have the same angle sizes.
Therefore, angle 8 has the same answer as angle 4, which is 123.5. Answer is C.
Answer:
x=403
Step-by-step explanation:
move all the terms that don't contain x to the right side and solve
