Answer:

12 white 28 printed

Step-by-step explanation:

x = white y = printed

x + y = 40————(1)

4.95x + 7.95y = 282————(2)

Solve for x using 1st equation

x = 40 - y Plug in for x using 2nd equation

4.95(40 - y) + 7.95y = 282 Solve for y

198 - 4.95y + 7.95y = 282

3y = 84

y = 28         Plug in for y using 1st equation

x + (28) = 40     Solve for x

x = 12

I hope this helped and please mark me as brainliest!

Answer:

12 white shirts and 28 printed shirts

Step-by-step explanation:

1. 4.95x + 7.95y = 282

x + y = 40

2. Guess and Check

12 + 28 = 40

4.95 (12) + 7.95 (28) = 59.4 + 222.6

59.4 + 222.6 = 280

3. Answer: 12 white shirts and 28 printed shirts

You can do elimination or substitution, but in this case, I feel like it would've been too complicated.

Mirror the speed of 16.8 m/s Olympian ran the 100 m dash in 9.6 seconds how much faster was Sarah the cheetah speed to the neare
Fiesta28 [93]

Answer:

6.4 meters per second

Step-by-step explanation:

Sarah the cheetah ran 100 meters at a speed of 16.8 meters per second. An olympian ran the 100-meter dash in 9.6 seconds. How much faster was Sarah the cheetah’s speed, to the nearest tenth of a meter per second?

0.9 meters per second

1.6 meters per second

6.4 meters per second

10.4 meters per second

Speed = distance / time

Olympian's speed = 100 / 9.6 = 10.4 meters per second

Sarah's speed = 16.8 meters per second.

Difference in speed = 16.8 - 10.4 = 6.4

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

Ravi and his wife are each starting a saving plan. Ravi will initially set aside $125 and then add $40.75 every week to the savi
katen-ka-za [31]

Answer:

  T = 125 +116.40N

Step-by-step explanation:

The total savings is the sum of the two plan values:

  T = A + B

  T = (125 +40.75N) +(75.65N) . . . . substitute the given formulas

  T = 125 + (40.75+75.65)N . . . . . . .combine like terms

  T = 125 +116.40N

Find the roots of the quadratic equation w+w²/3=0​
Daniel [21]

I assume that the equation you mean is below:

\large \boxed{w +  \frac{ {w}^{2} }{3}  = 0}

To find roots for this equation, we have to get rid of the denominator. We can do by multiplying both sides by 3.

\large{w(3) +  \frac{ {w}^{2} }{3} (3) = 0(3)} \\  \large{3w +  {w}^{2}  = 0}

Factor w-term out (common factor)

\large{w(3 + w) = 0} \\  \large{w = 0 \:  \:  \:  or \:  \:  \: 3 + w = 0} \\  \large{w = 0, - 3}

Answer

  • The roots of quadratic equation are 0,-3
