Work backwards to solve
leva [86]

Answer: $14.93

Step-by-step explanation:

First, lets remove the shipping price: 51.65 - 3.50 = 48.15

Next, lets find the sales tax of the shirts: 48.15 x 0.07 = 3.37

Then, subtract that from the shirt price: 48.15 - 3.37 = 44.78

Finally, divide 44.78 by 3: 44.78 / 3 = 14.93!

X 5.2.19
Semmy [17]

Answer:

Step-by-step explanation:

y = ax² + bx + c

Plug the points into the equation to get a system of 3 equations with 3 unknowns a, b, and c.

-27 = 4a - 2b + c

-42 = 9a + 3b + c

-12 = a + b + c

(a,b,c) = (-4,1,-9)

y = -4x² + x - 9

A weight lifter can bench press 189 kg. How many milligrams (mg) is this?
Inessa [10]

A weight lifter can bench press 189 kg. How many milligrams (mg) is this?

Answer: We know that:

1kg=1,000,000 mg

We are given, that a weight lifter can bench press 189 kg

Therefore, a weight lifter can bench press:

189 \times 1,000,000 mg

189,000,000mg

18.9 \times 10^{7} mg

Therefore, 18.9 \times 10^{7} mg is equal to the 189 kg
