Answer:

3x=total amount of money, 3x

Step-by-step explanation:

Because the number of notes books is the same (x and x), you can simply add them.

Basically, the equation is 1x+2x= total cost but you can add 1x and 2x because they have the same variable

Solve algebraically 16 = 64 - 32t
GaryK [48]

Answer:

t= 3/2 (i think this is what you meant?)

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

16=64−32t

16=64+−32t

16=−32t+64

Step 2: Flip the equation.

−32t+64=16

Step 3: Subtract 64 from both sides.

−32t+64−64=16−64

−32t=−48

Step 4: Divide both sides by -32

I know the answer is no solution but I don't know how to get it☹️ plz help!
Crank
When a linear equation is in the form y = mx + c, the c, or constant, is the intercept on the y axis, meaning it crosses the y axis at (0, 1).

The gradient (1/3 in this case) is how much the y increments (or decrements) per increase of 1 of the value of x.

This would mean that there would be one point at (0, 1), and another at (3, 2). Draw a line from these two points and beyond, and that is the graph sketched.
