Essica and her sister, Nicole, need money for lunch. Jessica receives $50 and buys lunches at the high school for $2.50 each and Nicole receives $40 and buy lunches at the elementary school for $1.50 each. How many lunches do they have to buy for the two girls to have the same amount of money in their account? $50 - $1.50x = $40 - $2.50x
$50 - $1.50x = $40 - $2.50x

$50 - $2.50x = $40 - $1.50x
$50 - $2.50x = $40 - $1.50x

$50 + $1.50x = $40 + $2.50x
$50 + $1.50x = $40 + $2.50x

$50 + $2.50x = $40 + $1.50x

Answer asap ill give ! ’ a sample of radioactive material decays over time. the number of grams, y , of the material remaining x days after the sample is discovered is given by the equation y = 10(0.5)^x. what does the number 10 represents in the equation? a. the half-life of the radioactive material, in days b. the amount of the sample, in grams, that decays each day c. the time, in days, it will take for the samples to decay completely d. the size of the sample, in grams, at the time the material was discovered

Which equation shows y= 3 4 x− 5 2 in standard form? a 4x−3y=10 b 3x−4y=10 c 3x−4y=−10 d 4x−3y=−10
