What is -30+-30-30-30

Answers

Answer 1

Answer:

-120

Step-by-step explanation:

-30

but you have -30 -30 -30

what if we add it to make -90

then we have -30

same thing if you forgot to put + like

-30 + -30 + -30 + 30

still would be -120

5/6-1/9=?/?-?/? =13/18

Answers

15/18 - 2/18 = 13/18

Find the least common multiple of 6 and 9. The LCM is 18. In order to get 18 on the denominator with 6, you have to multiply by 3 because 6 times 3 is 18. You have to multiply 3 to the numerator, so 5 times 3 is 15. Thus, the first fraction is 15/18. To get the second, you need to find what would get you 18 on the denominator with 9. You need 2, so 9 times 2 is 18. You have to multiply 2 to the numerator, so 1 times 2 is 2. Thus, the second fraction is 2/18.

ZA and ZB are vertical angles. If m_A = (4x – 13)° and m
ZB = (3x + 19)', then find the measure of ZA.

Answers

Answer:

115 degrees

Step-by-step explanation:

Vertical angles are congruent by the vertical angles theorem.

Hence,

<A=<B

4x-13=3x+19

x=32

Substituting 32 in for x in <A

4(32)-13= 115

Can 10, 11, 2 be measures of the sides of a triangle

Answers

Answer:

Yes

Step-by-step explanation:

The Triangle Inequality Theorem says the sum of any two side lengths of a triangle has to be greater than the third side.

With the measures of 10, 11, and 2, this follows the theorem.

For example, 10 + 11 is 21, which is greater than 2.

11 + 2 is 13, which is greater than 10.

This works for all the combinations, so 10, 11, and 2 can be the side lengths.

If 3(x + 5) = 39, then what is x?

Answers

Answer:

x=8

Step-by-step explanation:

X=8 because 39/3 is 13 and 13- 5 is 8 and 5 and 8 add up to make 13 inside the parenthesis.

Answer:

x = 8

Explanation:3(x + 5) = 39Divide Both Sides By 3

3(x + 5) / 3 = 39 / 3

Simplify

x + 5 = 13

Subtract 5 From Both Sides

x + 5 - 5 = 13 - 5

x = 8

What value of x makes the equation 3(x – 6) – 8x = –2 + 5(2x + 1) true? Explain your answer

Answers

Answer:

x = -7/5

Step-by-step explanation:

3( x - 6 ) - 8x = -2 + 5(2x + 1)

3x - 18 - 8x = -2 + 10x + 5

-5x - 18 = 3 + 10x

-5x - 10x = 3 + 18

Layla right her scooter 360 miles every week, she rides 60 miles every 3 hours. At this rate, how many hours will take Layla to ride 360miles.

Answers

Answer:

It will take Layla 6 hours to ride 360 miles

Step-by-step explanation:

The answer is 18 hours. It takes her 3 hours for 60 miles. 60 times 6 equals 360. So she had to ride 60 miles 6 times to get to 360 miles. Which means 6 times 3. So your answer is 18 hours.

Suppose a chemist combines a 25% acid solution and a 50% acid solution to make 40 L of 45% acid solution. How many liters of each solution did she use? Use the blanks below to fill in your numerical answers.

Answers

Answer:

The number of liters for :

Acid solution a = x = 8 liters

Acid solution b = y = 32 liters

Step-by-step explanation:

Let us represent:

The number of liters for :

Acid solution a = x

Acid solution b = y

Suppose a chemist combines a 25% acid solution and a 50% acid solution to make 40 L of 45% acid solution.

x + y = 40 ...... Equation 1

x = 40 - y

25% × x + 50% × y = 45% × 40

0.25x + 0.5y = 18...... Equation 2

We substitute, 40 - y for x in Equation 2

0.25(40 - y)+ 0.5y = 18

10 - 0.25y + 0.5y = 18

- 0.25y + 0.5y = 18 - 10

0.25y = 8

y = 8/0.25

y = 32 Liters

Solving for x

x = 40 - y

x = 40 - 32

x = 8 Liters.

Hence:

The number of liters for :

Acid solution a = x = 8 liters

Acid solution b = y = 32 liters

Melanie has a bag that contains orange chews, cherry chews, and peach chews. She performs an experiment. Melanie randomly removes a chew from the bag, records the result, and returns the chew to the bag. Melanie performs the experiment 61 times. The results are shown below: A orange chew was selected 38 times. A cherry chew was selected 5 times. A peach chew was selected 18 times. Based on these results, express the probability that the next chew Melanie removes from the bag will be peach chew as a decimal to the nearest hundredth.

Answers

Answer:

0.30

Step-by-step explanation:

Given that:

Total number of trials = 61

Number of orange chews = 38

Number of cherry chews = 5

Number of peach chews = 18

Probability that next chew removed will be a peach chew ;

This is an experimental probability problem ;

Using the relation :

Experimental probability of A;

Number of successes (A) / total number of trials

Hence, Probability that next chew removed will be a peach chew ;

Experimental probability of peach chew :

Number of trails = 61 ; number of successes (peach chew) = 18

P(peach chew) = 18 / 61

P( peach chew) = 0.2950819

= 0.30 ( nearest hundredth)
