1.5( x + 4) -3 = 4.5 ( x - 2 )

Hitman42 [59]

Answer:

Step-by-step explanation:

1.5(x + 4) - 3 = 4.5(x - 2)

1.5x + 6 - 3 = 4.5x - 9

1.5x + 3 = 4.5x - 9

3 + 9 = 4.5x - 1.5x

12 = 3x

12/3 = x

What are two ways to find the difference 13/50 - 4.93

PtichkaEL [24]

Answer:

Find the two ways to find the difference of : $\frac{13}{50} -4.93$

First way:

$\frac{13}{50}$

To convert this fraction into decimal.

We have to make the denominator 100.

i.,e

$\frac{13}{50} = \frac{13 \times 2}{50 \times 2}= \frac{26}{100} = 0.26$

now,

$0.26-4.93 = - 4.67$

Second way:

Convert $\frac{13}{50}$ to $\frac{26}{100}$ and 4.93 to $\frac{493}{100}$ ,

Now:

$\frac{26}{100}-\frac{493}{100} = \frac{26-493}{100} =-\frac{467}{100} = -4.67$

Please help me. Due tonight.

Answer:

The sum of the interior angles of any triangle are equal to 180

therefore in this triangle, m<a+m<c+m<b=180

we know that 9x-26 and m<a are supplementary angles (meaning they add to 180) and therefore,

9x-26+a=180

9x+a=206

a=206-9x

(206-9x)+(2x-12)+(4x+43)=180

combine like terms

-3x+237=180

-3x=-57

x=19

if x=19 then we can substitue it in for c

4x+43=c

4(19)+43=c

c=119
