Two numbers add to 191 and the second is 57 bigger than the first. what are the two numbers? can i get steps

Take away 57 from the total to make the two numbers equal:

191 - 57 = 134

Divide by 2 to find the smaller number:

134 ÷ 2 = 67

Add 57 back to the number to find the bigger number:

67 + 57 = 124

The smaller number is 67 and the bigger number is 124

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

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:
