Step-by-step explanation:
step 1. 4x + 27 + 3x = 90 (definition of a rectangle)
step 2. 7x = 63 (collect like terms. subtract 27 from both sides)
step 3. x = 9 (divide both sides by 7)
Multiply the first equation by -2 to give
4x - 2y = 6
-x + 2y = 3 Adding:-
3x = 9
x = 3
Plug x = 3 into second equation:-
-3 + 2y = 3
2y = 6
y = 3
Answer is x=3, y = 3
Answer:
Step-by-step explanation:
12 in = 1 ft
(4 in)/sec × (1 ft)/(12 in) = (4/12 ft)/sec = (⅓ ft)/sec
Answer:
B
7 less than 3 times a number (X) is (3x-7), and then the sum of these two numbers means we have (3x-7)+X, and then we know this equals 109, leaving us with:
(3x-7)+x = 109
$250 is the answer but if u add and then do division and boom ur answer is $250
