What is 26.99 round to the nearest tenth
Arte-miy333 [17]
Salutations!

To round to the nearest tenth, you need know whether the number next to tenth place is greater than 5 or lesser than 5. If its greater than 5, you need to round up. If its lesser than 5, you need to round down. Now, in the number 26.99 9 is in the tenth place. The number next to 9 is greater than 5, so just add on to the ones place, making the tenth and hundredth place 0. Zero has no value so whether you add the zero or not, it does not matter.

<span>26.99 round to the nearest tenth </span>≈ 27

Hope I helped (:

Have a great day!

Work out the value of angle x
Alexus [3.1K]

well, it's isosceles so use base angles theorem

the top angle is also x

90 + 2x = 180

subtract 90 from both sides

2x = 90

divide both sides by 2

x = 45 degrees

Write the expression as a single term.<br> 3ln(x+2) - ln(x - 1)
Dafna1 [17]

Answer:

ln  [(x + 2)^3 ]/(x-1)

Step-by-step explanation:

3ln(x+2) - ln(x - 1) =  ln (x + 2)^3  -  ln (x-1)

ln (x + 2)^3  -  ln (x-1) =  ln  [(x + 2)^3 ]/(x-1)
