2.25/100 x =630
x= 630 x 100/2.25
x= 28000
To make this easier, you need to change the fractions by multiplication.
-3/4x=15 - First, you multiply 4 to both sides of the equation
(4)-3/4x=15(4)
-12/4x=60 - Simplify
-3x=60 - Divide by -3 on both sides
x=-20 -> (-20,0)
Do the same to find the y-intercept, to get (0,18)
Answer:
Step-by-step explanation:
n and d are the number of nickels and dimes, respectively.
"there are 20 coins"
n+d = 20
d = 20-n
"total value is $1.40"
0.05n + 0.10d = 1.40
0.05n + 0.10(20-n) = 1.40
-0.05n + 2 = 1.40
0.05n = 0.6
n = 12
d = 20-m = 8
<h2>|| <u>Question</u> ||</h2>
