The solution is actually pretty simple. All you have to do is plug the numbers in corresponding the letters like a with a b with b and calculate
7). 6(6)+(5)^2-(3)^2=52
And you do the same thing with 8) you get 180
Fill 12 gallon tank for $48.74.
or buy gas for $3.80 a gallon.
$3.80 x 12= $45.60.
buying gas is cheaper by $3.14.
Answer: do not know
Step-by-step explanation:
Answer:
700
Step-by-step explanation:
Let x be the smaller amount and y be the larger amount.
Then,
equation a-----x=y-200
equation b----x/y=5/7
Replace the value of x from equation a in equation b
=>(y-200)/y=5/7
=>7y-1400=5y
y=700
Answer:
Slope = 3
Step-by-step explanation:
For a proportional relationship, the slope of the line is simply y/x.
So using any given pair of values from the table, say (1, 3), the slope is:
y/x = 3/1
Slope = 3
