Answer:
the ratio would be 6.75:4.5:3:2
Step-by-step explanation:
replace d and c with
d=2 and c=3
Then using proportion multiplication, you will find that b is 4.5
now replace all b with 4.5.
Then again using proportion multiplication, you will get a is 6.75.
Plug in a, b, c, d in the ratio and you get 6.75:4.5:3:2
Answer is 0.5
-2 divided by -4 equals 0.5
and same thing for the rest of the equation.
Answer:
5x - 43

To simplify the above, we'll go ahead and use the numbers outside the parentheses to multiply the ones inside to clear the parentheses as seen below;

So the answer is 5x - 43
You would just have to isolate for x
so it would simply become
-1.56/-7.8
= 0.2
