Answer:
X=8, each side is=27
Step-by-step explanation:
Equilateral triangle, each side has the same lenght
5x-13=11x-61
61-13=11x-5x
48=6x
x=8
5(8)-13=27
Answer:
1/2, 9/16, 5/8, 3/4
Step-by-step explanation:
Answer:
y = 2(31x + 336)
Step-by-step explanation:
The surface area of an open rectangular box of sides, l, w and h is
A = 2lh + 2wh + lw where l = length = x, w = width = 14 in and h = height = 24 in.
Since A = y, we have
y = 2lh + 2wh + lw
y = 2x(24) + 2(24)(14) + x(14)
y = 48x + 672 + 14x
y = 62x + 672
y = 2(31x + 336)
When they have no solutions, the lines are parlaell, or they have the same slope but different y intercept
example
3x+2y=2 and
3x+2y=4 are paralell
also
y=3x+2 and
y=3x+4 are also parlell, no solutions
infinite solutions are when they are the same line
they have the same slope and y intercept
to find out, simplify
3x+2y=4 and
6x+4y=8 are smae lien
also
y=3x+2 and
2y=6x+4 aer the same line
1 solution is when it is none of the above things
a normal thing, where the slopes are differnet
example
y=2x+2
y=3x+2
Answer:
20
Step-by-step explanation:
16-12/4+3(6-2) subtract 6 and 2
16-12/4+3+4 divide 12 and 4
16-3+3+4 subtract 16 and 3
13+3+4 add all 3 numbers
13+7
20
