Answer:

x=26

Step-by-step explanation:

we know that

m∠KOL+m∠LOM+256°=360° -----> by complete circle

substitute the given values and solve for x

$(x+3x)\°+256\°=360\°\\4x=360-256\\4x=104\\x=26$

Please help me with this as well

Answer:

$y = \dfrac{3 + 6\sqrt{2}}{4} ~~~\textrm{and}~~~y = \dfrac{3 - 6\sqrt{2}}{4}$

Step-by-step explanation:

$(4y - 3)^2 = 72$

$4y - 3 = \pm\sqrt{72}$

$4y - 3 = \pm 6\sqrt{2}$

$4y = 3 \pm 6\sqrt{2}$

$y = \dfrac{3 + 6\sqrt{2}}{4}~~~\textrm{or}~~~y = \dfrac{3 - 6\sqrt{2}}{4}$

Eight more than four times a number is negative twelve

quester [9]

The equation is 4x+8=-12 so you subtract 8 from both sides to give you 4x=-20, then you divide by 4 to get x=-5

The larger of two numbers is eight more than three times the smaller number. The sum of the two numbers is fifty-two. Find the t

Alina [70]

Let $x$ be the larger number and $y$ the smaller number.

The first sentence translates to $x=8+3y$ . The second translates to $x+y=52$ .

Since $x=8+3y$ , you can substitute this into the second equation to get

$(8+3y)+y=4y+8=52\implies 4y=44\implies y=11$

Then substituting this into the original second equation gives

$x+11=52\implies x=41$
