How do you solve x/9-1/3=-5/3

Answers

Answer 1

Answer:

Answer:

$x = ( - 18)$

Step-by-step explanation:

$(x)/(9) - (1)/(3) = ( - (5)/(3) ) \n (x)/(9) = - (5)/(3) - (1)/(3) \n (x)/(9) = - (6)/(3) \n (x)/(9) = - 2 \n 9 * (x)/(9) = - 2 * 9 \n x = - 18$

at the car wash fundraiser jenna's team washed 14 cars in 45 minutes. if they keep up at that rate, how many cars can the team wash in 2.5 hours? how did you get the answer

Answers

You can write it as a proportion and then solve the proportion.
(2.5 hours is 150 minutes)
14 cars x cars
--------------- = -------------------
45 minutes 150 minutes

Then solve.

x=46.6666666
So that is about 47 cars

Use the Law of Sines to solve the triangle. Round your answers to two decimal places.A = 110.8°, C = 18.2°, a = 25.3

Answers

Answer:

Can't be solved.

Step-by-step explanation:

Answer: B = 43.9 , b = 18 71 , c = 8.45

Step-by-step explanation:

from the law of sine,

a b c

--------- = ---------- = ----------- a =25.3, C = 18.2 degree, A = 110.8 deg.

Sine A Sine B Sine C

to get the value of c,

a c

--------- = -----------

Sine A Sine C,

25.3 c

----------- = -------------

Sine 110.8 Sine 18.2

Now cross multiply to get the value of c

c x Sine 110.8 = 25.3 x Sine 18.2

Therefore c = 25.3 x Sine 18.2

------------------------

Sine 110.8

checking for Sine 18.2 in your log tables/calculators , ie, sine 18 under 2, = 0.3123 and sine 110.8 = 0.9348

c = 25.3 x 0.3123

--------------------

0.9348

= 8.45.

To get angle B, sum total of a triangle is supplementary ie, 180 degree.

meaning that A + B + C = 180

Therefore, angle B = 180 - ( 110.8 + 25.3)

= 180 - 136.1

= 43.9

Now to find b,

b c

------------- = ------------

Sine B Sine C

b 8.45

--------- = ------------

Sine 43.9 Sine 18.2

b x sine 18.2 = 8.45 x Sine 43.9

b = 8.45 x 0.6934

--------------------

0. 3123

b = 18.708

= 18.71.

The final Answer = B = 43.9, b = 18.71, c = 8.45

Anthony writes a numerical expression 2+10x3-2 and says that the expression has a value of 34. Is Anthony correct? Explain your answer.

Answers

Answer:

Anthony is incorrect

According to the order of operations(PEMDAS), you must first multiply 10 × 3

which equals 30, then you add 2, which equals 32, finally you subtract 2, which brings you back to 30

10 × 3 = 30

2 + 30 - 2 = 30
