Step-by-step explanation:
we know
1 yard = 0.000568 mile
now,
Formula
Formula divide the length value by 1760
= 46745534/1760
= 26559.9625 miles
Answer:
$145.00
Step-by-step explanation:
Since w is the number of weeks, substitute the w in (25+8w) with 15
y = 25 + 8(15)
y = 25 + 120
y = 145
The student saved $145.00 after 15 weeks
D should be the correct answer
Answer:
x = 11/3 = 3 2/3
y = 13/3 = 4 1/3
Step-by-step explanation:
Here, we want to solve the system of equations simultaneously
x + y = 8
2x -3 = y
From the second equation, we have an equation for y
we can simply proceed to substitute this into the first equation
x + 2x - 3 = 8
3x - 3 = 8
3x = 8 + 3
3x = 11
x = 11/3
Recall;
y = 2x - 3
y = 2(11/3) - 3
y = 22/3 - 3
y = (22-3(3))/3
y = (22-9)/3 = 13/3
