URGENT To decorate his new room, Mr. Caldwell bought some succulents for $2 each and
some mini cacti for $1 each. If he bought a total of 15 plants and spent a total of $23,
how many plants of each kind did he buy? Write and solve a system of equations. Show all work!

Succulents=8

Cacti=7

Step-by-step explanation:

x will be how much succulents he bought and y would be how many cacti he bought.

x+y=15.  Since he bought 15 plants.

2x+y=23

x=8

y=7

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:

i would you but i don't under stand the qustion
