Answer:

-4

Step-by-step explanation:

Take the second term and subtract the first term

50 -54 = -4

We can check by taking the third term and subtracting the second term

46-50 = -4

The common difference is -4

If we will analyze, we will notice a standard:

  • From 54 to 50 we subtracted 4 --> (-4);
  • From 50 to 46 we subtracted 4 --> (-4);

This is repeated until last term of sequence.

Terefore, the correct alternative is letter d).

Multiply 2 5/8 and -2 3/5
Rina8888 [55]

Answer:

-6 33/40

Step-by-step explanation:

2 5/8  * -2 3/5

Change each to an improper fraction

2 5/8 = (8*2+5)/8 = 21/8

2 3/5 = (5*2+3)/5 = 13/5

21/8 * -13/5

-273/40

Change to mixed number

40 goes into 273 6 times

6*40 = 240   273-240 =33

-6 33/40

Help me solve this pls
ddd [48]

Answer:

\frac{x - 10}{8}

Step-by-step explanation:

\frac{3x}{8} - \frac{x + 5}{4}

The common denominator of both fractions is 8. Therefore,, divide the denominator of each fraction, then multiply what you get by the numerator of each fraction.

Thus:

\frac{1(3x) - 2(x + 5)}{8}

\frac{3x - 2x - 10}{8}

\frac{x - 10}{8}
