The cost for 2 shirts and 4 ties is $56, while the cost of 3 shirts and 2 ties is $54. Construct a system of linear equations to fondo the cost for 1 shirt and 1 tie. (Hint: first define your variables

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

ask the math teacher she or he would know lol.
