Answers

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°

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

15 vanilla and 6 mint chip

$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

if the ratio of dogs to cats is 1 to 2 and there is a total of 21 animals how many are dogs

Answers

Answer:

Step-by-step explanation:

Let   cats = x  and dogs = y

and given conditions are ,

dog: cat= 1:2

y:x=1:2

y/x = 1/2

x=2y

also given that

total animals = 21

x+ y=21     putt x=2y we get

2y +y =21

3y = 21

y = 7  Dogs

putt y = 7 in above equation we get

x+7=21

x=14 Cats
There are 7 dogs and 14 cats

Every one dog there are two cats 1:2
Also could be written as (cats) 7:12 (dogs)
