The information from the first equation gives you the information needed for the second. To solve the first equation you must rearrange the equation to isolate X. In order to do that you can first move the 3 to the other side of the equation by subtracting it from both sides (5x + 3 - 3 = 4 - 3) and then simplify that to (5x = 4 - 3) and further to (5x = 1). Then to move the 5 you must divide both sides by 5 so you get (5x/5 = 1/5) which can be simplified to (x = 1/5)
From this you can use the X value and input it into the second equation
Y = -3(1/5) and then solve for Y.
Hope this helps!
8/ (1 1/2) = 36/x....8 muffins to 1 1/2 tsp = 36 ( 3 doz) muffins to x tsp
this is a proportion, so we cross multiply
(8)(x) = (1 1/2)(36)
8x = 3/2 * 36
8x = 108/2
8x = 54
x = 54/8
x = 6 3/4 <=== 6 3/4 tsps are needed to make 3 doz muffins
Answer:
14
Step-by-step explanation:
Answer:
m = 2.8
Step-by-step explanation:
Multiply both sides of the equation by the inverse of the coefficient of m. That coefficient is 1/7, so its inverse is 7/1 = 7. Then you have ...
7·2/5 = 7·m/7
14/5 = m . . . . . . . . simplify
m = 2 4/5 = 2.8 . . express the number in a manner that makes sense to you
Answer:
208-n
Step-by-step explanation:
208 is Miguel number and in is Kristen. Miguel has a greater number of pages than Kristen so you would have to subtract n from it. Hope this helps! :)
