Answer:
Step-by-step explanation:
Let
x------> amount of baseball cards Isaac had before he sold
we know that
so
Solve for x
(4+x) + x = 18; 2x=14; x=7; width = 7, length = 11
Answer:
x = 5
Step-by-step explanation:
6(3 - 7x) = -192
Divide each side by 6
6/6(3 - 7x) = -192/6
3 - 7x = -32
Subtract 3 from each side
3-7x-3 = -32-3
-7x = -35
Divide each side by -7
-7x/-7 = -35/-7
x = 5
Expanding it, we get 1.3*8-1.3b+3.7b=-5.2 using the distributive property. Next, we get 10.4+2.4b=-5.2. Subtracting 10.4 to both sides, we get -15.6=2.4b. Dividing 2.4 from both sides, we get b=-15.6/2.4=-6.5
