Answer: x = 29 and y = 28

Step-by-step explanation:

Opposite angles in parallelogram are equal.

So,

A and C are opposite angles.

B and D are opposite angles.

4x = 4y + 4

3y - 20 = 2x + 6

Solve these two equations to find x and y.

Max spends three times as long on his math homework than he does on his science homework. If he spent total of 64 minutes on mat
den301095 [7]

Let X = science homework.

Then math homework would be 3x ( three times as long).

Now you have math plus science = 64 minutes:

x  + 3x = 64

Combine like terms:

4x = 64

Divide both sides by 4:

x = 64 / 4

x = 16

He spent 16 minutes on science and 48 minutes on math.

Ted is saving for a toy. He has no money now, but
sweet-ann [11.9K]

Answer:

4D - 1

Step-by-step explanation:

So, if Ted saves $D for 4 weeks, then this amount will be equal to 4D because multiplication is simply repeated addition. We can imagine this situation as D+D+D+D, for the 4 weeks he is saving. We can simplify this to 4D in the expression.

Next, the question tells us that this will be 1 dollar more than needed. So, if we want to find the cost, we need to subtract that dollar.

Thus, the final expression is 4D - 1 because this represents 1 dollar less than the money he saves for 4 weeks.
