Answer:

The system has no solutions

Step-by-step explanation:

Here, we want to solve the given equation systems

we can simply rewrite the second equation as;

y = 7-8x

So, let’s equate the two y

-8x + 6= 7-8x

As we can see, we have -8x on both sides of the equation and this means that there is no solution to system

This is because no value of x will make it that the addition of 6 to -8x will

be same as that of adding 7

How many dimensions does a point in space have

Andreas93 [3]

Hello, hope you are having a wonderful day.

A point has 0 dimensions. It has no length, width, or depth.

So any point in space has 0 dimensions.

Now, a line has 1 dimension.

Rectangles, squares and other shapes have 2 dimensions.

Cylinders, cubes, cones and other figures have 3 dimensions.

Hope it helps. Please mark Brainliest; I really need it.

How do i find the value of x , i’m so confuseddd !

olasank [31]

Answer:

x ≈ 61.3

Step-by-step explanation:

Using the Sine rule, that is

$\frac{6}{sinx}$ = $\frac{5.8}{sin58}$ ( cross- multiply )

5.8 × sinx = 6 × sin58° ( divide both sides by 5.8 )

sin x = $\frac{6sin58}{5.8}$ ≈ 0.87729, thus

x = $sin^{-1}$ (0.87729) ≈ 61.3

Yung bought $4.60 worth of bubble gum. Each piece of gum cost $0.10. How many pieces of bubble gum did Yung buy?

Readme [11.4K]

Answer:

Yung bought 46 pieces of bubble gum for $4.6

Explanation:

We are given that each piece of gum cost $0.1 and that he spent $4.6 on gums

To get the number of gums he bought, we will simply use cross multiplication as follows:

1 piece .........................> 0.1

x pieces ......................> 4.6

Therefore:

$x = \frac{4.6*1}{0.1}= 46$ pieces of gum

Hope this helps :)
