You are given that 4a-2b=10
Write down the value of 2a-b

The value of 2a - b in the given expression is 5

From the question,

We are to write down the value of 2a - b

The given expression is 4a - 2b = 10

To determine the value of 2a - b, we will factorize the given expression and then solve for 2a - b

From the given expression,

4a - 2b = 10

Factorizing, we get

Now, divide both sides by 2

∴

Hence, the value of 2a - b is 5

The answer is in the image 

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45 

The answer is in the image 

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7

The solution is in the following image

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

The answer is in the image 

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg
