Answer:
x = 9
Step-by-step explanation:
"The sum of 42 and a number x is 51" in "mathy" words:
42 + x = 51
Then, subtract both sides by 42:
42 + x - 42 = 51 - 42
So
x = 9
1. A
Two triangles are said to be in perspective (or as some would call it, homologous) from a point if their corresponding vertices form three lines that intersect in that single point (called a colinear point). Desargues' theorem asserts that if two triangles are in perspective from a point, then they are also perspective from a line (called the perspectrix<span>); for this reason perspective triangles are also calles coplanar triangles.
2. B (13)
</span>The series of numbers shown in the question is known as the Fibonacci Sequence. <span>The next number in the sequence is found by finding the sum of the two numbers that precede it.
</span>
1 = 0+1
<span>2 = 1 + 1
3 = 1 + 2
5 = 3 + 2
8 = 5 + 3
Next number is 13 (8 + 5)</span>

Answer is 119
Hope this helps:)
Answer:
Part B: is -60 divided by -10
Part C: is The number of increments is positive.
Part D: is -1 times 60 / -1 times 10
Part E: is Any number divided by itself is 1. In the expression -1 times 60, the -1s in the numerator and the denominator cancel each other out to give the result 60/10, or 6
Part F: is There are 6 increments of -10 feet in -60 feet.
Part G is: copy and paste -10 feet 6 times
Part H: is -60 / 4 increments
Part I: is there is one negative number in the expression, so the solution will be negative. There isn't a -1 in the denominator to cancel out the -1 in the numerator.
Part J: is -60 /4 =-15 Alex’s elevation change in each increment was -15 feet.
Step-by-Step Explaination: I did the test.
