The correct equation would be: 2.) 0.05(x+4) + 0.10x = $1.25
A nickel is worth 5 cents. A dime is worth 10 cents.
no. of nickels = x + 4
no. of dimes = x
nickels + dimes = 1.25
0.05(x + 4) + 0.10x = 1.25
0.05x + 0.20 + 0.10x = 1.25
0.15x = 1.25 - 0.20
0.15x = 1.05
0.15x/ 0.15 = 1.05 / 0.15
x = 7 *no. of dimes.
no. of nickels = x + 4 = 7 + 4 = 11
To check:
0.05(11) + 0.10(7) = 1.25
0.55 + 0.70 = 1.25
1.25 = 1.25
Answer:
B. 0.72
Step-by-step explanation:
8/11 = 0.72
<span>Center City West = x
</span><span>Center City East = (x + 257)
Solve for x to find the capacity for Center City West and then we can find the capacity for Center City East.
(x + 257) + x = 1221
x + x + 257 = 1221
2x + 257 - 257 = 1221 - 257
2x = 964
2x / 2 = 964 / 2
x = 482
</span><span>Center City West capacity = 482
</span>
Now to find Center City East capacity we substitute 482 for x in (x + 257)
(x + 257)
(482 + 257)
482 + 257 = 739
Center City East capacity = 739
Center City West capacity = 482
Answer:
It's not 5x + 100 = 180,
it's 5x = 180 because they are vertical angles.
x = 36
y = - 
x - 3
the equation of a line in ' slope intercept form ' is
y = mx + c
where m is the slope and c the y-intercept
here m = - and c = - 3
thus y = - x - 3 is the slope- intercept equation
