Answer:
x = 21
Step-by-step explanation:
the angles 5x - 35 and 3x + 7 are vertical angles and congruent, thus
5x - 35 = 3x + 7 ( subtract 3x from both sides )
2x - 35 = 7 ( add 35 to both sides )
2x = 42 ( divide both sides by 2 )
x = 21
Answer: 
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:

Solving for "x", you get:

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:

Answer:
Options (B) and (D)
Step-by-step explanation:
If two triangles have the same size and shape they are said to be congruent triangles.
Triangles given in the attachment,
Triangles A and E appear to be congruent.
And triangles C and F appear to be congruent.
[Since corresponding sides of these triangles don't appear to be the same in measure]
Remaining triangles B and D do not appear to be congruent.
Therefore, Options (B) and (D) will be the answer.
Answer:
51
Step-by-step explanation:
450 < 10x - 1x
450 < 9x
50 < x
you must sell 50 tickets to break even; 51 to make a profit
Answer:
Yes, they are equivalent, and the second question is B
Step-by-step explanation:
If you add x on both sides of equation A, then it comes up to 5x+2=6, which is equivalent to equation B. For the second question, you are just basically adding a variable to each side, so it is B.
