Answer:
x = 128
x - 23 = 105°
Step-by-step explanation:
x - 23° = 105° because these angles are corresponding
x = 105 + 23
x = 128
The value of the angle marked x - 23 = 105
Answer:
11 hours
Step-by-step explanation:
let he works at first store x hours and at car wash y hours. Then
x+y=25
multiply by 4
4x+4y=100 ...(1)
12x+15y=333
divide by 3
4x+5y=111 ... (2)
(2)-(1) gives
y=111-100=11
Answer:
d
Step-by-step explanation:
it fits correctly to the description
To solve an exponential equation, take the log of both sides, and solve for the variable. Example 1: Solve for x in the equation . Ln(80) is the exact answer and x=4.38202663467 is an approximate answer because we have rounded the value of Ln(80).. Check: Check your answer in the original equation.
