Answer: 45 mph
Step-by-step explanation:
We know that Rob was driving 63 mph which is 18 miles faster than pigeons, therefore you subtract to get the answer.
63-18=45
The trick is to get the X all alone on one side. Start by subtracting 2 from both sides. This wqould give you -1/2X+2-2=-x+7-2 or simplified to -1/2x=-x+5. Next, add x to both sides to give you -1/2x+x=-x+5+x. This simplifies to +1/2x=5. Multiplying by 2 on both sides will get rid of the fraction. Therefore 2*1/2x=5*2. This simplifies to your final answer of x=10.
Answer:
None of them are proportiionsal
Step-by-step explanation:
Remember you can do anything to an equation as long as you do it to both sides
(y/4)-49=-9
isolate the variable
add 49 to both sides
y/4=40
multiply both sides by 4 to clear fraction
y=160
