Here are the equations that are represented by the scenarios:
4x + 2y = $14 (Joe)
3x + y = $9 (Becca) or y = 9 - 3x
To find the cost of each burger and fry you will solve the second equation for y and substitute it in for the y in the first equation. This will put everything in terms of x, the price of a fry.
4x + 2(9 - 3x) = $14
4x + 18 - 6x = 14
-2x +18 = 14
-18 -18
<u>-2x</u> = <u>-4</u>
-2 -2
x = 2
Fry cost $2, and burgers cost (9 - 3 x 2) or $3.
Answer: the 3 and 2 first then 40 divided by 8 then 8x2 then you can put the rest in whatever order i used pemdas I think it should be correct
Step-by-step explanation:pemdas
Take $1.75 from the $10 then dived the 55cents into the sum. Thus $10 - $1.75 = $8.25. / .55 =15 miles exactly
Answer:
QPR = 73
Step-by-step explanation:
there opposite angles so there equal, therefore we set them equal to each other
(6x+25)=(10x-7)
-4x= -32
x= 8
plug in
6(8)+25
73
