Weegy: If five times a number plus two is 17, the number is 3.
5n + 2 = 17
5n =17-2
5n=15
n=15/5
n = 3
User: Given the formula K = LMN, what is the formula for M?
A. M = KL/N
B. M = K/LN
C. M = LN/K
D. M = LNK Weegy: Given the formula K = LMN, the formula for M is
M = K /LN. User: Given the formula D = ABC, what is the formula for C?
A. C = AD ÷ C
B. C = D ÷ AB
C. C = ABD
D. C = AB ÷ D Weegy:
Given the formula D = ABC, the formula for C is
C =D / AB. User: Find the value of Z in the following equation: 8Z = 64.
A. 72
B. 512
C. 56
D. 8 Weegy: 8Z = 64; Z = 64/8; Z = 8 User: Solve this inequality: 3p – 6 > 21.
A. p > –5
B. p > 9
C. p > –9
D. p > 5
Weegy: 3p - 6 > 21 3p > 21 + 6 3p > 27 p > 9 User: Solve this equation: y/9 + 5 = 0.
A. y = 5
B. y = –45
C. y = –5
D. y = 45 Weegy: y /9 + 5 = 0 y /9 = -5 y = -5(9) = -45 User: Simplify this expression: 4p + 9 + (–7p) + 2 = ?
A. 3p + 7
B. 3p + 11
C. –3p + 11
D. 11p + 11 Weegy: 4p + 9 + ( 7p) + 2 = -3p + 11 User: Solve the inequality: 12p + 7 > 139
A. p > 11
B. p > 18
C. p > 154
D. p > 12 Weegy: 12p + 7 > 139 12p > 139 - 7 12p > 132 p > 132/12 p > 11 User: Simplify and solve this equation: 4m + 9 + 5m – 12 = 42.
A. m = 4
B. m = 5
C. m = –5
D. m = -4 Weegy: 4m + 9 + 5m - 12 = 42
(4m + 5m) + (9 - 12) = 42
9m - 3 = 42
9m = 42 + 3
9m = 45
m = 45/9
m = 5
