Answer:

x = 4

Step-by-step explanation:

We are to solve for;

-x = -4

A number (n) multiplied by x gives -4. What is the number?

n × x = -4

n is definitely equal to -1

So to get the value of x; we divide -4 by -1 to get 4

Therefore x = 4

What is the measure in each angle? A? B? C?

andrey2020 [161]

Answer:

∠A = 48°, ∠B = 48°, and ∠C = 84°

Step-by-step explanation:

AB = CB Given

m ∠A = m ∠C If opposite sides are =, then those opposite angles are =

6(x - 3) = 4(x + 1)

6x - 18 = 4x + 4

2x - 18 = 4

2x = 22

x = 11

m ∠A = 6(11 - 3) = 6(8) = 48°

m ∠C = 4(11+ 1) = 4(12) = 48°

The sum of the angles in a triangle = 180°

48° + 48° m ∠B = 180°

96°+ m ∠B = 180°

84° = m ∠B

Is is square root of 1.6875 a rational number

mamaluj [8]

Question:

Is square root of 1.6875 a rational number ?

Answer:

Square root of 1.6875 a rational number is not a rational number

Solution:

Given that we have to find square root of 1.6875 and determine if it is rational number or not

Let us first find square root of 1.6875

$\sqrt{1.6875} = 1.29903810568$

Let us understand about rational number

A rational number is a number that can be expressed as a fraction (ratio) in the form $\frac{p}{q}$ where p and q are integers and q is not zero.

When a rational number fraction is divided to form a decimal value, it becomes a terminating or repeating decimal.

So the number 1.29903810568 is not a rational number

In other words we can say,

Only the square roots of square numbers are rational. Here 1.6875 is not a perfect square. So it is not rational number

How do you solve -1x+20 is greater than -7+35

rusak2 [61]

$\huge\fbox{Hello~there!}$

Let's solve this inequality!

$\rm{-x+20>-7+35$

What can we do to solve this inequality? Well, first of all, we can add -7 and 35:

$\rm{-x+20>28$

Now, move 20 to the right, using the opposite operation:

$\rm{-x>28-20$

Subtract:

$\rm{-x>8$

Divide both sides by -1 to isolate x:

$\rm{x$ (Answer)

_____________

Additional comment

When we divide both sides of an inequality by a negative number, we flip the inequality sign.
