Answer:
¾ miles
Step-by-step explanation:
⅓ : ¼ mile
1 : X
X = ¾
3/8 = .375 so we want .375 of $5460.40 or .375 x $5460.40 = $2047.65 savings
To find the checking we simply subtract:
$5460.40 - 2047.65 = $3412.75 - checking
You could also do 5/8 or .625 x $5460.40 to get $3412.75
because 3/8 + 5/8 (or .375+.625) = 1 (1 whole amount to save - in this case $5460.40)
(3/8) / 1 = (3/4) / x.....3/8 oatmeal to 1 batch = 3/4 oatmeal to x batches
cross multiply
(3/8)(x) = (3/4)(1)
3/8x = 3/4
x = (3/4) / (3/8)
x = 3/4 * 8/3
x = 24/12
x = 2 <==== 2 batches were made
-75x - 36 = -21x²
-75x Seventy-five times a negative integer
-36 Minus 36
= Equals
-21x² The square of the negative integer
Hope this helps!
