Answer:
d = 25
Step-by-step explanation:
Perhaps you want to solve for d:
(0.3d -1.5)/(3 1/3) = 0.84/(7/15)
Change the division by a fraction to multiplication by its inverse.
(0.3d -1.5)·(3/10) = (0.84)·(15/7)
0.09d -0.45 = 1.8 . . . . . . . . . . . . simplify
d - 5 = 20 . . . . . . . . . . . . . . . . . . divide by 0.09
d = 25 . . . . . . . . . . . . . . . . . . . . . add 5
_____
Grouping symbols help show what is being divided by what. Especially where mixed numbers are involved, parentheses help show that the number 3 1/3 is not supposed to be interpreted as the product of 3 and 1/3.
Answer:
x = 4
FE = 8
Step-by-step explanation:
Congruent means equal. Notice how both F and C equal 30 degrees while line AC and line DF are both equal to 9 inches. This means we can equal line CB to line FE to find the value of x:
2x = x + 4
Isolate variable x by subtracting both sides by x:
2x - x = x - x + 4
x = 4
Check your work:
2(4) = 4 + 4
8 = 8
Correct
240 is the correct answer I think. First you multiply 6x10=60 then multiply 60x2 that equals 240.
Answer:
therefore, to produce 1000 watches , it would cost 9000 dollars.
Price : 9 dollars a watch
Step-by-step explanation:
C=6000 + 3x
what is the cost of producing 1000 watches?
first do this
C= (1000)= 6000 + 3(1000)
C= (1000)= 6000 +3000
C= 9000
