Mathematics
1 answer:
Elina [12.6K]3 years ago
6 0
'is' in mathematics means equal
'of' in mathematics means multiplication

percent means over 100

84 = 74% * x

84 = 74/100 * x

84 = 37/50 * x

Multiply 50/37 on both sides, so we can isolate 'x'

85 * 50/37 = x

x = 4250/37

x ≈ 114.864865

84 is 74 percent of <span>114.86</span>.

Answer:

123

Step-by-step explanation:

(1 + 7x) - 6 * (-7 - x) = 36<br> step pls
AlladinOne [14]

Answer:

-7/13

Step-by-step explanation:

(1 + 7x) - 6 * (-7 - x) = 36     Distribute the 6 into (-7 - x)

 1 + 7x + 42 + 6x = 36      Combine like terms (1 +  42) & (7x + 6x)

       43 + 13x = 36            Subtract 43 from both sides

           13x = -7                Divide by 13

           x = -7/13
