Answer:
g=2
f=5
Step-by-step explanation:
- add g to the other side on the 2nd equation. you should get f=7+g
- now replace the f in the top equation with 7+g. the equation should now look like 7+g +3g = 15
- combine like terms to get 7+4g=15
- subtract 7 from both sides to get 4g=8
- divide by four to get g=2
- now plug 2 in for g in the 2nd equation to get f-2=7
- add 2 to both sides and get f=5
Answer:
454cm
Step-by-step explanation:
perimeter of rectangle = 2(l+b)=2(1.52+0.75)=4.54meter =4.54*100 cm( 1m =100cm) = 454cm.
1: Thirty subtracted from four times a number is greater than the opposite of ten.
Let the number be x, so equation becomes :
2: Given equation is this states that the result of 27-2b is less than equal to opposite of six.

Answer:
f(x)=
1. 48x when x < or = 3,
2. 45x when 4 < or = x < or = 8
3. 42x when 9 < or = x < or = 19
4. 38x when x > 19
Step-by-step explanation:
3 boxes or less = Cost of tiles = $48
4 - 8 boxes ; cost = $45
9 - 19 boxes ; cost = $42
> 19 boxes ; cost = $38
