Since they are the angles of the triangle they should add up to 180.

angle R + angle S + angle T = 180

2x + 10 + 2x + 25 + x - 5 = 180

Combine like terms:

5x + 30 = 180
5x = 150
x = 30

SO the value of x is 30

Hope this helps :)

In a triangle, the three interior angles always add to 180°

m∠R + m∠S + m∠<span>T = 180

</span><span>(2x+10) + (2x+25) + (x-5) = 180
</span>2x+10 + 2x+25 + x-5 = 180
5x + 30 = 180
5x = 150
x = 30

Answer:

The total cost = $714

Step-by-step explanation:

Given

Monitor cost = $287

Scanner cost = $58

Keyboard cost = $49

Printer cost = $320

The total cost can be determined by adding the costs of all the pieces of equipment.

Thus,

Total cost = Monitor cost + Scanner cost + Keyboard cost + Printer cost

= $287 + $58 + $49 + $320

= $714

Therefore, the total cost = $714

Seven times the sum of 4 and some number is 42

Naddik [55]

Answer:

$x=2$

Step-by-step explanation:

$7\times{(4+x)}=42$

Divide both sides by 7:

$4+x=42\div{7}\\4+x=6$

Subtract 4 from both sides:

$x=6-4\\x=2$

azamat

Answer:

There are a 25% probability that Christine fails the course.

Step-by-step explanation:

We have these following probabilities:

A 50% probability that Christine finds a tutor.

With a tutor, she has a 10% probability of failling.

A 50% probability that Christine does not find a tutor.

Without a tutor, she has a 40% probability of failing.

Probability that she fails:

10% of 50%(fail with a tutor) plus 40% of 50%(fail without a tutor). So

$P = 0.1*0.5 + 0.4*0.5 = 0.25$

There are a 25% probability that Christine fails the course.
