Answer:
30
Step-by-step explanation:
Equation y = 3x + 210
if y = 10x
10x = 3x + 210
or, 10x - 3x = 3x + 210 - 3x
or, 7x = 210
or, x = 210 ÷ 7
or, x = 30
Answer:
6
Step-by-step explanation:
2 times the difference of a number and 1 = 4 plus that number
In other to express the word problem Mathematically ; let the number = x
2(x - 1) = 4 + x
Expand
2x - 2 = 4 + x
Collect like terms
2x - x = 4 + 2
x = 6
Hence, the number is 6
25×(1−0.18)^(4)
=11.30
25*0.01=25(1-0.18)^t
0.25=25(0.82)^t
0.25/25=(0.82)^t
t=log(0.25/25)/log(0.82)
t=log(0.25÷25)÷log(0.82)
t=23.21 hours
