Answer:
y=5
x=20 degrees
K= 43 degrees
L=137 degrees
Step-by-step explanation:
aducent angles of parralologram add to 180 degrees
so (6x+17)+ (2x+3)=180
or 6x+17+2x+3=180
so 8x+20=180
and 8x=160
x=20 degrees
opposite sides of parralologram are equal so
6y-13= 32-3y
or 9y=45
and y=5
opposite angles are coonguent so
ang K= 2x+3
so K= 43 degrees
aducent angles of parralologram add to 180 degrees
so ang L+43=180
and L=137 degrees

I entered the equation into a graphing calculator. clicked table and then scrolled down to the profit of $3,563. 55 skateboards
you could also try this equation. B=the number attached to x so 10, a=the number attached to x^2(or in other equation x^3 etc) so 1 and c is the number, so -12.
Answer:
She should have substituted y = 17 - 2x in the first equation
Step-by-step explanation:
3x + 4y = 33
2x + y = 17
y = 17 - 2x
3x + 4(17 - 2x) = 33
3x + 68 - 8x = 33
5x = 35
x = 7
y = 17 - 2(7)
y = 3
x = 7, y = 3
Only one solution
Answer:
yes it does. good job on your A.
Step-by-step explanation:
Let x be the digit in the tens place and y be the digit in the ones place.
so, the digit is xy
<span>
The ten's digit of a two digit number is 1 more than 4 times the units' digit.
</span>x = 4y + 1
<span>63 is subtracted from the number, the order of the digits is reversed
</span>10x + y - 63 = 10y + x
9x - 9y = 63
x = 4y + 1 ------------ (1)
9x - 9y = 63 ---------- (2)
Sub (1) into (2)
9(4y + 1) - 9y = 63
36y + 9 - 9y = 63
27y = 63 - 9
27y = 54
y = 2 ------- sub into (1)
x = 4(2) + 1 = 9
x = 9, y = 2
The number is 92
