Answer:
3/10
Step-by-step explanation:
Just multiply all of the numerators (top numbers) and then multiple all of the denominators (bottom numbers)
2/3x3/4x3/5 would be 18/60 Then take any number that is a factor to both 18 and 60 and divide both numbers by that factor. I could use 2 or 3 or 6 because both 18 and 60 is divisible by any of these numbers. I will choose 3. I will divide the top and bottom of 18/60 by 3 to get 6/20, now I will divide the top and bottom of that number by 2 to get 3/10
Answer: the number is 3
Step-by-step explanation:
Let the number be represented by x.
If 4 more than 4 times a certain number is the same as 4 more than the product of 3 and 4, it means that
4x + 4 = 4 + 3×4
4x + 4 = 4 + 12
4x + 4 = 16
Subtracting 4 from the left hand side and the right hand side of the equation, it becomes
4x + 4 - 4 = 16 - 4
4x = 12
Dividing the left hand side and the right hand side of the equation by 4, it becomes
x = 12/4 = 3
Answer:
Store 1= $150
Store 2= $250
Step-by-step explanation:
Let the amount invested by store 1 be x while store 2 be y hence
10x-8y=1300 Eqn 1
Make x the subject of the formula for the first equation
10x=1300+8y divide both sides by 10
X=130+0.8y
6x+5y=2250 Eqn 2
Substituting where there’s x with 130+0.8y in equation 2 we obtain
6(130+0.8y)+5y=2250
780+4.8y+5y=2250
9.8y+780=2250
9.28y=2250-780=1470
Y=1470/9.8=150
X=130+0.8y= 130+0.8(150)=250
B= 3
(7+5b)+1
(7+5(3))+1
(7+15)+1=23
22+1=
23
