Write a system of equations that can be used to solve the following problem. then solve the system and determine the answer. jaafar owns a total of 50 shares of stock, some in stock a and some in stock b. on a particular day, stock a closed at $74 per share and stock b closed at $84 per share. if jaafar's stock for these companies was worth $4040, how many shares of each type of stock does he own? let x denote the number of shares of stock a that jaafar owns. let y denote the number of shares of stock b that jaafar owns. write the equation corresponding to the first sentence of the problem statement ("jaafar owns a total of 50 shares of stock"). the first equation is x plus y equals 50. write an equation relating x and y that corresponds to the second and third sentences of the problem statement. the second equation is 74 x plus 84 y equals 4040. jaafar owns nothing shares of stock a and nothing shares of stock b.

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

happy to

pls mark as brainliest

what are you trying to solve here

step-by-step explanation:

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
