Solve the system algebraically<br> x+3y=11<br> 4x-4y=7
ololo11 [35]

Answer:

x = 65/16,   y = 37/16

Step-by-step explanation:

solve the system algebraically

x+3y=11

4x-4y=7

Try substitution.

let  x =  11 - 3y

Plug in.

4(11 - 3y) - 4y = 7

44 - 12y - 4y = 7

44 - 16y = 7

37 = 16y

y = 37/16

x = 11 - 3*y

x = 11 - 3*(37/16)

x = 11 -  111/16

x = 65/16

URGENT!!LAST QUESTION!!!! PLS JUST TAKE A LOOK! EASY BUT I AM DUMB!!!!!! WILL GIVE BRANLIEST!! The following two triangles are s
3241004551 [841]

Answer:

x = 26.25 inches

Step-by-step explanation:

Since we know the triangles are similar, we can simply set up ratios to find the length of side length 'x'.

\frac{15.75}{x} = \frac{9}{15}

Cross multiply:

236.25 = 9x

Divide both sides by '9' to solve for 'x':

\frac{236.25}{9}  = \frac{9x}{9}

x = 26.25

Therefore, side length 'x' equals 26.25 in.
