Y=3x+18 -12x+4y=-24 linear system of equations

Mathematics
1 answer:
solong [7]3 years ago
7 0

Answer:

Step-by-step explanation:

Use substitution, y=3x+18 so -12x+4(3x+18)=-24. From here you can try to solve for x

-12x+12x+72=-24

The xs cancel, which leaves you with 72=-24

Since 72 cannot equal -24 there is no answer to this system of equations

If pencils sell at 6 for 59 cents how many pencils can be bought for 2.95
Olegator [25]
We already know from the given data that 6 pencils can be bought for 59 cents. We have to determine the number of pencils that can be bought for $2.95.
So
Price of 6 pencils = 59 cents.
Price of 1 pencil = (59/6) cents
                           = 9.83 cents
Now total amount in hand for buying pencils = $2.95
                                                                       = 295 cents
Then the number of pencils that can be bought for 295 cents = (295/9.83)
                                                                                                   = 30.01
So the maximum number of pencils that can be bought for $2.95 is 30 pencils.

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°
