Simplify |-3| + 6 ÷ (4 - 1) · 8. 8 13 19 24

Dima020 [189]

Answer:

Step-by-step explanation:

The equation has "absolute value" , "addition", "subtraction", "division", and "multiplication", and "parenthesis".

The order we follow here would be:

PEMDAS, which is "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction"

Also, note, we can do absolute value first, before these.

Now let's simplify using PEMDAS:

$|-3|+6/(4-1)*8\\=3+6/(4-1)*8\\=3+6/3*8\\=3+2*8\\=3+16\\=19$

So the answer is 19 (note: i used "/" sign for "division")

1+2+2²+2³+...+2^x=1023

mrs_skeptik [129]

$1 + 2 + 2^{2} + 2^{3} + 2^{x} = 1023 \\3 + 4 + 8 + 2^{x} = 1023 \\7 + 8 + 2^{x} = 1023 \\15 + 2^{x} = 1023 \\2^{x} = 1023 - 15 \\2^{x} = 1008 \ln(2^{x}) = ln(1008) \\xln(2) = ln(16 * 8 * 7) \\xln(2) = ln(2^{4} * 2^{3} * 7) \\\frac{xln(2)}{ln(2)} = \frac{4ln(2) + 2ln(3) + ln(7)}{ln(2)} \\x = 4 + \frac{2ln(3)}{ln(2)} + \frac{ln(7)}{ln(2)}$

En una botella caben 2.75 litros de agua. ¿Aproximadamente cuántos galones caben en la botella?1 espacio l i t r o casi igual a

Naddik [55]

Answer:

0.726 galones

Step-by-step explanation:

De la pregunta anterior, se nos dice que

1 botella = 2.75 litros de agua

Se nos pide encontrar cuántos galones puede contener.

En la pregunta, nos dicen

1 litro = 0.264 galones

2.75 litros =

Multiplicación cruzada

2.75 litros × 0.264 galones

= 0.726 galones.

Por lo tanto, 0.726 galones pueden caber en la botella

Solve the equation for x by graphing -2x + 3 = -3(-x) - 2

adoni [48]

Answer:

x = 1

Step-by-step explanation:

There are a couple of ways to solve this. One is to graph the left side of the equation, graph the right side of the equation, and look for the point where those graphs intersect. It is at x = 1. The first attached graph shows this solution.

Another method for solving such an equation is to subtract one side from the other and look for the value of x that makes the resulting expression zero.

(-2x +3) -(-3(-x) -2) = 0

A graphing calculator doesn't need to have this simplified. If it is simplified, it becomes ...

-5x +5 = 0

So, the graphed line is y = -5x+5. Its x-intercept is x=1, the solution of the original equation. The graph of this is shown in the second attachment.
