Answer:
(x) = │ x - 4│+ 3
Step-by-step explanation:
Answer:
son age: X
man_age= 5X
in 3 years: we have: (man_age+3)(X+3)=380
we can replace the man age by 5X and we get :
(5X+3)(X+3)=380
it is a quadratic equation with 2 solutions. One negative and 7
The solution is thus 7, since age can not be negative.
The son is thus 7 and the dad 5 times more 35
Step-by-step explanation:
BC is 21 meters.
2x + 5 + 3x = 45
5x + 5 = 45
5x = 40
X = 8
2(8) + 5 = BC
21 = BC
1. 3/4
2. 3/4
3. 3 whole parts one missing part
4. 0.75 75% 6/8
5. It’s closer to 1 on a number line because it’s more then 1/2
6. A fraction greater could be 7/8 Bc it’s more then 6/8 and 6/8 is equal to 3/4
A fraction less then could be 1/4 Bc 1 is less then 3
