How to figure out 5 - 0.53
sveta [45]

the answer would be 4.47

because every whole number is made out of 100 small parts.

So that would be like 400-53 which is 447 and then add the decimal point. That would make it 4.47

If R is the midpoint of TS, TR = 5x - 12, and RS = 3x + 8, find TS.
GenaCL600 [577]

Answer:

5x -12 = 3x +8 (set the two = each other because they are the same length)

2x- 12= 8 (subtract 3x from both sides)

2x = 20 (add 12 to both sides)

x=10 (what x= for both expressions)

5(10) -12 (plug it into the first one to see what the length is and to see they're =

50 - 12 ( I already multiplied, now subtract)

38 (what the length of TR is)

3(10) +8 (plug it in again but into the other expression)

30+8 (multiply and add)

38 (the two have the same answer, so the x-value is correct.)

38+38= 76 (add the lengths of RS and TR and you get the length of TS)

Step-by-step explanation:

I hope this helps :)

Evaluate the expression: −(8 − 12) + 60 + (−4)2.<br> A) 13<br> B) 20<br> C) 21<br> D) −11
k0ka [10]

Answer:

56.

Step-by-step explanation:

= -(8-12)+60+(-4)*2

= -(-4)+60+(-4)*2

= 4+60+(-4)*2

= 4+60+-4*2

= 4+60-4*2

= 4+60-8

= 64-8

= 56
