x=7-2t
Move 7 to the other side. Sign changes from +7 to -7.
x-7=7-7-2t
x-7=-2t
Divide by -2 for both sides
x/-2-7/-2=-2t/-2
x/2+7/2=t
Answer: t= x/2+7/2 or t=7/2+x/2
Answer:
1st
Step-by-step explanation:
The two triangles are similar by AA
Firstly, we can see that angle LKM and QKR are congruent as they are vertical angles.
The second set can be identified by noticing that RM is a transversal through 2 parrallel lines LM and QR. That manes QRK, and LMK alternate interior angles, showing that the angles are congruent. Hence similarity by AA
Answer:
B. the product of two irrational numbers
Step-by-step explanation:
To be a rational number, we need to multiply two irrational numbers
An example would be
sqrt(2) * sqrt(2) = sqrt(4) = 2
Answer:
1. Term.
2. Common difference.
3. Arithmetic sequence.
4. Sequence.
Step-by-step explanation:
1. Term: an individual quantity or number in a sequence. For example, 1, 2, 3, 5, 6. The first term is 1 while 5 is the fourth term.
2. Common difference: the fixed amount added on to get to the next term in an arithmetic sequence. For example, 2, 4, 6, 8 have a common difference of 2 i.e (6 - 4 = 2).
3. Arithmetic sequence: a sequence in which a fixed amount such as two (2) is added on to get the next term. For example, 0, 2, 4, 6, 8, 10, 12.... is an arithmetic sequence.
4. Sequence: a set of numbers that follow a pattern, with a specific first number. For example, 1, 2, 3, 4, 5, 6 is a sequence.
