Answer:
a = 4 b = 5
Step-by-step explanation:
8a + 12b = 92......eqn 1
6a - 4b = 4......eqn 2
multiply eqn 2 by 3
18a - 12b = 12.....eqn 2
add eqn 1 and 2 to eliminate b
26a = 104
a = 4
put a = 4 into eqn 2
18(4) - 12b = 12
72 - 12b = 12
72 - 12 = 12b
60 = 12b
5 = b
Their houses are nine miles away from each other. Mark rides his bike at a rate of twelve miles per hour. Each hour consists of sixty minutes; therefore I would do 60/12 to get five, representing him being able to do one mile in five minutes. Hence, you shall perform 9*5 or nine times five to get the answer of fourty-five minutes.
12 MILES PER HOUR
60 divided by 12 = 5 minutes
ONE MILE PER 5 MINUTES
9 multiplied by 5 = 45 minutes
I hope this helps.
1) distribute 2 to each term within the parentheses
2) combining like terms ( which means subtract a 6-2)
3) subtract 4 from both sides of the equation
4) divide both sides of the equation by 4
Final answer should be ( x = 1/4 )
There are 16 oz in 1 pound.

Therefore, 34 lbs = 544 oz
Answer:
<h3>P=6s</h3>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>tips and formulas:</h3>
- a linear function is function with two variables one dependent another one is independent
<h3>let's solve:</h3>
since we can see what linear function is
the second condition is the best fit
<h3>The perimeter of a square, P, where the length of each side of the square is B represented by s</h3><h3>(P = 4s)</h3>
therefore
our answer is b
