Answer:

m = -1

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write out equation

-13 = 5(1 + 4m) - 2m

Step 2: Parenthesis (distribute)

-13 = 5 + 20m - 2m

Step 3: Combine like terms (m)

-13 = 5 + 18m

Step 4: Subtract 5 on both sides

-18 = 18m

Step 5: Divide both sides by 18

-1 = m

Step 6: Rewrite

m = -1

Answer:

m = -1

Step-by-step explanation:

-13 = 5(1 + 4m) - 2m

Step 1 : Distributive Property

-13 = 5 + 20m - 2m

Add like terms

-13 = 5 + 18m

Subtract 5 on both sides

-18 = 18m

Divide

$\frac{-18}{18}$ = $\frac{18m}{18}$

m = -1

If you started counting when you first learned how to count and then counted by ones, eight hours a day, 5 days a week for 50 we

xenn [34]

Answer:

The number they would count is $\approx 0.49\cdot10^{-2}\ \%}$

Step-by-step explanation:

One mole is equal to 6.02214076x10^23 particles. In order to know the number counted by every human on Earth we simply multiply the number of humans times the count a "good counter" can achieve, 4x10^9x7.44x10^9 (for USA, change to 4x10^12 if you use de British English definition). Thus:

$\displaystyle{\frac{4\cdot10^9\cdot7.44\cdot10^9}{6.02214076\cdot10^{23}}=\frac{2.976\cdot 10^{19}}{6.02214076\cdot10^{23}}\approx 0.49 \cdot 10^{-4}\approx 0.49\cdot10^{-2}\ \%}$

You need to add two mixed numerals.
One is positive and one is negative.
To add a positive number and a negative number, first take the absolute value of both, making them both positive. Then subtract the smaller absolute value from the larger absolute value. Finally, the sign of the answer is the same sign as the number that has the larger absolute value.

The numbers are -4 5/8 and 2 1/8

Take absolute values:
|-4 5/8| = 4 5/8
|2 1/8| = 2 1/8

Subtract the smaller absolute value from the larger absolute value.

4 5/8 - 2 1/8 = 2 4/8 = 2 1/2

The greater absolute value is 4 5/8.
Since the number with the larger absolute value was -4 5/8, a negative number, the answer is negative, -2 1/2

-4 5/8 + 2 1/8 = - 2 1/2
