Someone help me solve this it's easy i just don't understand simple math

Lady_Fox [76]

Answer:

The equation — E = mc2 — means "energy equals mass times the speed of light squared." It shows that energy (E) and mass (m) are interchangeable; they are different forms of the same thing. If mass is somehow totally converted into energy, it also shows how much energy would reside inside that mass: quite a lot.

At a restaurant the cost for a breakfast taco and a small glass of milk is $2.10. The cost for 2 tacos and 3 small glasses of mi

tangare [24]

Answer:

The price for a small glass of milk is $0.95, and the price for a breakfast taco is $1.15.

Step-by-step explanation:

Let the price of a taco be x and the price for a small glass of milk be y.

$x + y = 2.1$

$2x + 3y = 5.15$

Multiply the first equation by 2:

$2x + 2y = 4.2$

Subtract the new third equation from the second equation:

$(2x + 3y) - (2x + 2y) = 5.15 - 4.2$

$y = 0.95$

Hence, the price for a small glass of milk is $0.95.

Substitute y into the first equation.

$x + 0.95 = 2.1$

$x = 1.15$

Therefore, the price for a breakfast taco is $1.15.

Hope this helped!
