Solve for g. -3+5+6g=11-3g−3+5+6g=11−3g

PtichkaEL [24]

Answer: $\mathrm{No\:Solution}$

Step-by-step explanation:

$\begin{bmatrix}-3+5+6g=1\\ 1-3g+5+6g=11-3g\end{bmatrix}$

$\begin{bmatrix}1-3\left(-\frac{1}{6}\right)+5+6\left(-\frac{1}{6}\right)=11-3\left(-\frac{1}{6}\right)\end{bmatrix}$

$\begin{bmatrix}\frac{11}{2}=\frac{23}{2}\end{bmatrix}$

$\frac{11}{2}=\frac{23}{2}\:\mathrm{\:is\:false,\:therefore\:the\:system\:of\:equations\:has\:no\:solution}$

There is a bag with only red marbles and blue marbles.

natulia [17]

Answer:

There must be 35 red marbles.

Step-by-step explanation:

This question can be solved using a rule of three.

A probability is the number of desired outcomes divided by the number of total outcomes.

The probability of randomly choosing a red marble is 7/9.

This means that for each set of 9 marbles, 7 must be red.

There are 45 marbles in total in the bag and each is equally likely to be chosen. Work out how many red marbles there must be.

How many red marbles out of 45?

7 red - 9 marbles

x red - 45 marbles

$9x = 45*7$

Simplifying by 9

$x = 5*7$

$x = 35$

There must be 35 red marbles.

A rocket generates a net force (F) of 2,050,000 newtons, and the rocket’s mass (m) is 40,000 kilograms. Use the formula F = ma t

Fofino [41]

2,050,000 = 40,000 * a
a = 2,050,000 / 40,000 = 51.25 m/s^2

A/b(2x-12)=c/d solve for x

GenaCL600 [577]

Let's solve for x.

Layout equation:

a/b

(2x−12)=c/d

Step 1: Multiply both sides by b.

2ax−12a=bc/d

Step 2: Multiply both sides by d.

2adx−12ad=bc

Step 3: Add 12ad to both sides.

2adx−12ad+12ad=bc+12ad

2adx=12ad+bc

Step 4: Divide both sides by 2ad.

2adx/2ad=12ad+bc/2ad

So the answer is x=12ad+bc/2ad.
