The given question is incomplete and has the following options
1) 35 t-shirts and 15 sweatshirts
2) 32 t-shirts and 18 sweatshirts
3) 25 t-shirts and 20 sweatshirts
4) 22 t-shirts and 22 sweatshirts
5) 15 t-shirts and 25 sweatshirts
Answer:
total money to be spent on clothing = $900
the only possible combination for this will be
25 t shirts and 20 sweatshirts
because 25*12 + 20 * 30 = 900
A system of equations is a collection of two or more equations with the same variables. When solving this system, u need to find the unknown variables. One way of solving a system of equations is by substitution.
example :
2x + 2y = 6 (equation 1)
3x + y = 4 (equation 2)
we need to pick a variable and isolate it. The easiest one to pick since it is already by itself is the y in the second equation.
3x + y = 4.....subtract 3x from both sides
y = -3x + 4
now we can sub -3x + 4 in for y in the 1st equation...u have to make sure u sub it back into the 1st equation and not the same equation u used to find it.
2x + 2y = 6.....sub in -3x + 4 in for y and solve for x
2x + 2(-3x + 4) = 6...distribute thru the parenthesis
2x - 6x + 8 = 6...subtract 12 from both sides
2x - 6x = 6 - 8...simplify
-4x = -2...divide both sides by -4
x = -2/-4
x = 1/2
now that we have a numerical number for x, u can sub this back into either of ur equations to find a numerical answer for y.
y = -3x + 4...when x = 1/2
y = -3(1/2) + 4
y = -3/2 + 4
y = -3/2 + 8/2
y = 5/2
so ur solution is : (1/2,5/2) <===
and u can check ur answers by subbing them into ur equations to see if they satisfy both equations...because for it to be a solution to this system, it has to satisfy both equations and not just one of them
Answer:
$2.50 per pound of apple
Step-by-step explanation:
Or if you have to write it as a fraction $2.50/ 1
the answer is A ,when x=0,g(x)is-1,so when u add x into the g(x),which is given below,u can find C,D,E,g(x) is no equal to -1,when you add x=1 into g(x)(A,B),you can find g(x) of B is 0,which is no equal the answer giving above(g(x)=2),but A is all right.
Answer:

Step-by-step explanation:
all you gotta do is find the difference, -49.62 minus -34.68, i suggest a calculator for things that are more difficult to do in your head
