Answer: If u divide both sides by 3 you get the value o x 2 answer: Combine terms by transporting. The equation becomes 4x -7x = -21
Step-by-step explanation: 1. 4x=7(x-3) -----> Start with the given.
2. 4x=7x-21 -----> Distribute 7 by multiplying it to the individual terms inside the parenthesis. 7(x) - 7(3) = 7x -21
3. -3x=-21 ------> From step 2, combine like terms by transposing. The equation becomes 4x - 7x = -21. Simplifying, it becomes -3x = -21
4. x = 7 -----> Divide both sides by -3, you get the value o x.
Hope this helps :)
Answer:
x = 9
Step-by-step explanation:
2 sides are 4 less than x, that is x - 4
The perimeter is the sum of all 3 sides, thus
x + x - 4 + x - 4 = 19, that is
3x - 8 = 19 ( add 8 to both sides )
3x = 27 ( divide both sides by 3 )
x = 9

Answer:
Step-by-step explanation:
Cost of 4 oranges = $x
cost of 1 orange= x/4
Cost of 10 oranges = x/4*10 = $ 2.5x
Cost of a custard apple = $1.25
Cost of n custard apple = 1.25*n = 1.25n
Cost of 4 bananas = $3
Cost of a banana = 3/4 = $0.75
Cost of (3n +1) bananas = 0.75*(3n+1) = 0.75* 3n + 0.75*1 = 2.25n + 0.75
Cost of fruits = 2.5x + 1.25 n + 2.25n + 0.75
= 2.5x + 3.50n +0.75
