You would add 6 to both sides, leaving the equation to say 3y+7=4y
Answer:
Since the perimeter is 56 inches we can solve for the lenght with this equation:
And solving for the length we got:
So then the lenght = 16 inhes and the width of 12 inches
Step-by-step explanation:
For a rectangle of width 12 inches and lenght y inches we know that the perimeter is given by:
Since the perimeter is 56 inches we can solve for the lenght with this equation:
And solving for the length we got:
So then the lenght = 16 inhes and the width of 12 inches
Least to greatest: 20,564 22,755 2,3805
Answer:
he is correct
Step-by-step explanation:
6+9 = 15
15 divided by 3 = 5
5 x 7 = 35
The correct answer is 370. A system of equations can be
used, where h represents the number
of calories in a hamburger and f represents
the number of calories in an order of fries. The equation <span> 2</span> h plus 3 f equals 1,700 represents the
fact that 2 hamburgers and 3 orders of fries contain a total of 1700 calories,
and the equation h<span> equals f
plus 50</span> represents the fact that one hamburger contains 50 more
calories than an order of fries. Substituting f plus 50 for h in
2 h plus 3 f equals 1,700 gives <span>2, parenthesis, f plus
50, close parenthesis, plus 3</span> f, equals 1,700. This equation
can be solved as follows:
2 f plus 100 plus 3 f equals 1,700
5 f plus 100 equals 1,700
5 f equals 1,600
f equals 320
<span>The
number of calories in an order of fries is 320, so the number of calories in a
hamburger is 50 more than 320, or 370.</span>
