2x+3=10^3 now solve for x.....hope it helps
Answer:
0.28125 or 9/32
Step-by-step explanation:
Answer:
a. The student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 50 is (8, 2).
Step-by-step explanation:
The second equation needs to be ...
5x +5y = 50
because the wording "short of $18" means that the actual cost of that purchase would be $18 more than the $32 that Harry had. 18+32 = 50.
The only answer choice that shows this as the second equation is choice A.

In fact, the solution to the system of equations is (8, 2), as can be seen in the graph below.
Answer:
23
Step-by-step explanation:
According to the diagram, two sum of <1 and <2 is 180 degrees
Hence 3x+30+81 = 180
3x+111 = 180
3x =180-111
3x = 69
x = 69/3
x = 23
