To solve this question, we will first expand the expression using the distributive rule: $x(y+z)=xy+xz$

Therefore:

$2g+3(g+5)=2g+3*g+3*5$

Simplify:

$2g+3g+15$

Add up like terms:

What is 1/8-10(3/4-3/8x)+5/8x

cluponka [151]

Answer:

x = 59/35

Step-by-step explanation:

Step 1: Distribute

1/8 - 10(3/4 - 3/8x) + 5/8x

1/8 - 30/4 + 30/8x + 5/8x

Step 2: Combine like terms

1/8 - 30*2/4*2 - 30/8x + 5/8x

1/8 - 60/8 + 35/8x

-59/8 + 35/8x

Step 3: Solve for x

-59/8 + 35/8x + 59/8 = 0 + 59/8

35/8x * 8/35 = 59/8 * 8/35

x = 59/35

Answer: x = 59/35

A toxic radioactive substance with the density of 4 mg/cm² is detected in the been detected in the ventilating ducts that was us

Kruka [31]

The formula for half-life is:

$A = P(0.5)^{t/h}$

A is the amount remaining, P is the initial amount, t is the time that has passed, and h is the half-life of the substance. Plug in the values that you know and solve:

$4 = P(0.5)^{35/20} \\ \\ 4 = P(0.5)^{1.75} \\ \\ P = \frac{4}{0.5^{1.75}} \\ \\ P \approx 13.4543426441$

Rounded to the nearest whole number, the density of the substance was about 13mg / cm².
