Answer:

pastel de manzana:  32

pastel de calabaza: 48

Step-by-step explanation:

pastel de manzana: x

pastel de calabaza: 80 -x

7 x + 6 (80 - x) = 512

7x + 480 - 6x = 512

pastel de manzana: x = 512 - 480 = 32

pastel de calabaza:  80 - 32 = 48

cheque: 7 x 32 + 6 x 48 = 512

HELP PLEASE. For parallelogram LMNO, if m∠L = 3x - 25 and m∠N = 2x - 10, find m∠M.
Dvinal [7]
In a parallelogram opposite angles are congruent, that means:

Angle L = Angle N, replace L & N by they respective value, then

3x-25 = 2x-10 ==> x=15 , Now plug the value of x in any of the 2 sides
3(15) -25 =20°

hence Angle L =- Angle N = 20°

Now let's calculate Angle M. In a parallelogram the adjacent angle are supplementary, that means their sum = 180°, then

Angle N + Angle N = 180°==> Angle M = 180°-20° = 160°

X+4y=10<br> -x+5y=8<br> what is the solution set
ziro4ka [17]

x + 4y = 10 \: \vee \:  - x + 5y \\ \Leftrightarrow \: x = 2 \: \vee \: y = 2 \\ \Rightarrow \: (x,y) = (2,2)
