Answer:

Y = 35 degrees

Step-by-step explanation:

The total degrees of a triangle always equal to 180. So here the question tells us the degree for 2 angles which is 60 and 85. From this, we can find the value of Y by subtracting: 180 - 60 - 85 = Y

35 = Y

-4÷[1/3(7-1/2)]+3<br>(pls show your work)

jek_recluse [69]

Step-by-step explanation:

= -4 ÷ ( 1/3 × (7 - 1/2) ) + 3

= -4 ÷ ( 1/3 × 13/2 ) + 3

= -4 ÷ 13/6 + 3

= -4 × 6/13 + 3

= -24/13 + 3

= -24/13 + 39/13

= 15/13

Please help me !!!!!!!!!!!!!!!!

Nutka1998 [239]

Answer: x=-10, y=13

Step-by-step explanation:

$-3x+2y=56\\-5x-2y=24$

+2y-2y = 0, eliminating y is much easier. So -3x-5x = -8x and 56+24 = 80

$-8x=80\\x=-10$

Substitute x in any equations but only 1 equation (Don't substitute in both equations.)

For me, I'd substitute x in -3x+2y=50

$-3(-10)+2y=56\\30+2y=56\\2y=56-30\\2y=26\\y=13$

So the answer is x = -10, y = 13

Work out an equation of the straight line with gradient 3 that passes through the point with coordinates (2, 4).

Gnom [1K]

Answer:

The answer is

$\huge \boxed{y = 3x - 10}$

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

$y - y_1 = m(x - x_1)$

where

m is the slope

( x1 , y1) is the point

From the question the point is (2, 4) and the slope is 3

The equation of the line is

$y - 4 = 3(x - 2) \\ y + 4 = 3x - 6 \\ y = 3x - 6 - 4$

We have the final answer as

$y = 3x - 10$

Hope this helps you
