3x+7+10x=7+13x+10 has {fill in blank} solutions.

-6x-6+8x=-5+2x-1 has {fill in blank} solutions.

choices for both are
infinitely many,one,two,three

Answers

Answer 1

Answer and Step-by-step explanation:

3x + 7 + 10x = 7 + 13x + 10

13x + 7 = 13x + 17

0 = 10

No solutions

-6x -6 + 8x = -5 + 2x -1

2x - 6 = -6 + 2x

0 = 0

Many solutions.

The first equation has no solutions.

The second equation has infinitely many solutions.

Answer 2

Answers:

1. No solutions

2. Infinitely many solutions

Step-by-step explanation:

[tex]3x+7+10x=7+13x+10[/tex]

Add common terms from both sides of the equation (10x and 3x) & (7 and 10)

[tex]13x+7=17+13x[/tex]

Subtract common terms from both sides (13x and 13x)

[tex]7\neq 17[/tex]

7 does not equal 17; thus, there are no solutions

[tex]-6x-6+8x=-5+2x-1[/tex]

Add common terms from both sides of the equation (-6x and 8x) & (-5 and -1)

[tex]2x-6=-6+2x[/tex]

Reorder the right side of the equation

[tex]2x-6=2x-6[/tex]

Since this is a true statement, there are infinitely many solutions

3x+7+10x=7+13x+10 Has {fill In Blank} Solutions.-6x-6+8x=-5+2x-1 Has {fill In Blank} Solutions.choices

Substance X is found in the bloodstream of humans. A random sample of 75 males had a mean content of 28 ppm of Substance X in their blood. A random sample of 50 females had a mean content of 33 ppm of Substance X in their blood. The population standard deviations for males and females are known to be 14.1 ppm and 9.5 ppm, respectively. Use the 88.12% degree of confidence. An appropriate set of null and alternative hypotheses to test whether males and females have the same amount of Substance X in their blood is:

Answers

Answer:

H0: u1 - u2 = 0

H1: u1 - u2 ≠ 0

Step-by-step explanation:

This question requires us to state the hypothesis to be used for this test to know if males and females have the same amount of substance X. I have gone further to also calculate the test statistics too.

Null hypothesis:

H0: u1 - u2 = 0

Alternative hypothesis:

H1: u1 - u2 ≠ 0

X1 = 28, sd1 = 14.1, n1 = 75

X2 = 33, sd2 = 9.5, n2 = 50

We have a 2 tailed test

Alpha = 1-0.8812

= 0.1188

Critical value = 1.56

If z<-1.56 or z>1.56

Reject null hypothesis

Test statistic

= (28-33)/14.1²/75 + 9.5²/50

= -2.37

Therefore we reject the H0 because -2.37 is less than -1.56

Which of the following shows the prime factorization of 72 using exponential notation?

Answers

The prime factorization of 72 using exponential notation is [tex]2^{3} *3^{2}[/tex].

It is required to find the prime factorization of 72.

What is a prime factorization ?

Prime factorization of a number is breaking a number down into the set of prime numbers which multiply together to result in the original number. The fundamental theorem of arithmetic says that every positive integer has a unique prime factorization.

Given that:

The prime factorization for 72 is

=2×2×2×3×3 .

=[tex]2^{3} *3^{2}[/tex]

Charlie saves $2 for every $9 he earns. Melody saves $4A for

Answers

Answer:

They are the same.

Step-by-step explanation:

Many ancient tombs were cut from limestone rock that contained uranium. Since most such tombs are not​ well-ventilated, they may contain radon gas. In one​ study, the radon levels in a sample of 12 tombs in a particular region were measured in becquerels per cubic meter (Bq/m3). For this​ data, assume that x(over-bar)= 3,469 Bq/m3 and s= 1,135 Bq/m3. Use this information to​ estimate, with 95% confidence, the mean level of radon exposure in tombs in the region. Interpret the resulting interval.

Answers

Answer:

95% confidence interval of the mean level of random exposure in tombs in the region.

(2746.868 , 4191.132)

Step-by-step explanation:

Step(i):-

Given sample size 'n'= 12

Mean of the sample  x⁻ = 3,469

and standard deviation of the sample 's' = 1,135

95% confidence intervals are determined by

[tex](x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} +t_{0.05} \frac{S}{\sqrt{n} } )[/tex]

Degrees of freedom = n-1 = 12-1= 11

Step(ii):-

95% confidence intervals are determined by

[tex](3469- 2.201 \frac{1135}{\sqrt{12} } , 3469+2.201\frac{1135}{\sqrt{12} } )[/tex]

Together, Lee and Joanna have 19 computer games. Joanna has 3 more games than Lee. Write and solve an equation to find the number of games each friend had.

Answers

Answer:

L=8 and J=11

Step-by-step explanation:

If Lee is L and Joanna is J we get: L+J=19.

And since Joanna has 3 more than Lee we get: J=L+3

When we substitute J for L+3 we get: 2L+3=19

When we solve we get: L=8

Finally, since J=L+3 we get: J=11

There are 3 fourth grade clases with a total of 90 scholars. 2/5 of the scholars have a sister. 1/2 of the scholars have a brother. How many scholars have a sisters?​

Answers

Answer:

There are 36 scholars who have a sister.

Step-by-step explanation:

Given that:

Total number of scholars in classes = 90

Fraction of scholars who have a sister = 2/5

Fraction of scholars who have a brother = 1/2

Number of scholars who have sisters = 2/5 of 90

Number of scholars who have sisters = [tex]\frac{2}{5}*90[/tex]

Number of scholars who have sisters = 36

Hence,

There are 36 scholars who have a sisters.

Answers

85 is not a prime, it’s a composite number.

Hello there!

85 is composite.

There are 3 ways of determining whether a number is prime or composite.

Check if the number is even. If it is, it's 100% compositeIf the number is odd, then look at its last digit. If it's 2, 4, 6, 8, 0 or 5, then it is composite.If the last digit is not 2, 4, 6, 8, 0 or 5, look at the factors of the given number. If it has 2 factors, then it's prime. If it has more than 2 factors, it's composite.

Step-by-step explanation:

hey i hope it helps you

2x+y=42(7)

8x+7y=36(1)

14x+7y=294

8x+7y=36

6x=258

divide both sides by 6

x=43

to get y

2x+y=42

equate x=43
