The age of the grandson is 7 years and the grandfather is 84 years if the grandson's age in months is equal to the age of grandpa in years and the difference in age is 77.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

Let's suppose the age of the grandsons is x years and

age of the grandfather's age is y years

Here some data are misprinted, so we are assuming the grandson's age in months is equal to the age of grandpa in years and the difference in age is 77.

Then according to the problem:

12x = y (as in 1 year, there are 12 months)

y -x = 77 (as difference in age is 77)

After solving both equations, we get:

x = 7 years and y = 84 years

Thus, the age of the grandson is 7 years and the grandfather is 84 years if the grandson's age in months is equal to the age of grandpa in years and the difference in age is 77.

9:39 PM A truck travels on a highway at a speed of 66 miles per hour. What is the speed of the truck in feet per second? Round y

Paul [167]

Answer:

$96.8\frac{feet}{second}$

Step-by-step explanation:

Remember that

$1\ mile =5,280\ feet$

To convert miles to feet multiply by 5,280

$1\ hour =3,600\ sec$

To convert hours to seconds multiply by 3,600

we have

$66\frac{miles}{hour}$

convert to feet per second

$66\frac{miles}{hour}=66(\frac{5,280}{3,600})=96.8\frac{feet}{second}$

Q.1 Write the algebraic expressions

Vanyuwa [196]

Answer:

(i) 4r + 3p (ii) 3q - 2p when 3q > 2p (iii) 2y + 2/3 x [not sure what [3] means]

Step-by-step explanation:

So for part (i) 3 multiply p added to 4 times r = 3p + 4r

For part (ii) since subtraction can seem like a negative number you stipulate that 3q is greater than 2p so that is will hold true!

(iii) I'm not sure what the [3] means but just using the numbers $\frac{2}{3}$ x, since of means multiply and add 2y then you have 2y + $\frac{2}{3}$ x
