Answer:

The number is -7.

Step-by-step explanation:

Let the number be = x

when twice the number is added to three times one more than the number. Mathematically, we can denote this as:

2x+3(x+1)  

She gets the same result as when she multiplies four times one less than the number.

4(x-1)

Now, both the results are same, so we will equate them same.

2x+3(x+1)=4(x-1)

=> 2x+3x+3=4x-4

=> 5x+3=4x-4

=> 5x-4x=-4-3

This gives x = -7

So, the number Pasha was thinking was -7.

We can check this:

2(-7)+3(-7+1)=4(-7-1)

=> -14+3(-6)=4(-8)

=> -14-18=-32

=> -32=-32   (checked)

Find the missing value to the nearest hundredth. cos_= 6/19
Olenka [21]

Let , missing value(_)=A

As, it is given that ,

CosA=\frac{6}{19}\\\\ Cos A=0.3158\\\\ A=72 {\text{Degree}}

To convert the value of A into Radians,

360°=2 π Radians

1 {\text{degree}}=\frac{\pi}{180}\\\\72 {\text{Degree}} =\frac{72\times 22}{180 \times 7}\\\\=1.2571

So, missing value to the nearest hundredth= 1.26 Radians
