Hi there! For these types of problems, you will have to solve them by using order of operations, which is in the form of PEMDAS. First you do parenthesis, then exponents, then multiplication and division from left to right and addition and subtraction from left to right. So for this question, we divide first. t is 8. 72/8 is 9. Now, we multiply. 9 * 2 is 18. For the last steo, we add. r is 24. 24 + 18 is 42. There. The value of the expression is 42.
Answer: 65

Answer:
1042
Step-by-step explanation:
-38,-8,22,52
The common difference is 52 - 22 = 30
a_1 = -38
a_2 = -38 + 30
a_3 = -38 + 2 * 30
a_4 = -38 + 3 * 30 (notice that the common difference is multiplied by 1 less than the term number)
a_n = -38 + (n - 1)30 (since the term number is n, we multiply the common difference by n - 1)
a_n = -38 + 30(n - 1)
a_37 = -38 + 30(37 - 1)
a_37 = 1042
The answer would be x=18. First you set it up by setting up an equation;
166=7x+40. Then you subtract 40 from each side. Last, you divide both sides by 7 and you should get x=166 or 166=x.
