Gio baked 21 cupcakes for the holiday sale. He made some with vanilla icing, and some with mint-chip icing. He charged $2 for the vanilla cupcakes, and $4 for the mint-chip cupcakes and made $54. How many of each did he make? He created the following system of equations to find out how many of each he made. Let x represent the number of vanilla cupcakes, and y represent the number of mint-chip cupcakes.
x+y=21
2x+4y=54
Answers
$2(15) + $4(6) = $54
Answer: 15 vanilla and 6 mint
Step-by-step explanation:
You would solve for x and get x=21-y and then plug that into the next equation and get 2(21-y)+4y = 54.
You would then solve for y.
42-2y + 4y = 54
42+2y =54
Then subtract 42 from both sides.
2y = 12, and then divide by 2.
You get y=6.
Then we know we sold 21 cupcakes so
21-6=x
15=x

Answer:
27°
Step-by-step explanation:
XWY and VWY are supplementary
∴ XWY + VWY = 180°
∴ XWY = 180° - VWY
XYW and ZYW are supplementary
∴ XYW + ZYW = 180°
∴ XYW = 180° - ZYW
ΔXWY is a right triangle at X
∴ XWY + XYW = 90°
∴ 180° - VWY + 180° - ZYW = 90°
∴ 180° - 6x + 180° - 4x = 90°
∴ 360° - 10x = 90°
∴ 10x = 270°
∴ x = 27°

x=2yalso given that
total animals = 21
x+ y=21 putt x=2y we get2y +y =21
3y = 21
y = 7 Dogsputt y = 7 in above equation we get
x+7=21
x=14 CatsEvery one dog there are two cats 1:2
