Answer:

Speed of Jennifer on Sunday [tex]=45[/tex] mi/hr

Step-by-step explanation:

Let speed of Jennifer on Saturday be x mi/hr

On Saturday morning, it took Jennifer 3.6 hours to drive to her mother's house for the weekend.

Distance travelled by Jennifer on Saturday = Speed × Time [tex]=3.6x[/tex] miles

Speed of Jennifer on Sunday = [tex](x-5)[/tex] mi/hr

On Sunday evening, due to  heavy traffic, it took Jennifer 4 hours to return home.

Distance travelled by Jennifer on Sunday = Speed × Time [tex]=4(x-5)[/tex] miles

As distance is obviously same on both Saturday and Sunday,

[tex]3.6x=4(x-5)\\3.6x=4x-20\\20=4x-3.6x\\20=0.4x\\x=\frac{20}{0.4}\\ x=50[/tex]

Therefore,

Speed of Jennifer on Sunday = [tex](50-5)=45[/tex]  mi/hr

[tex]x=\frac{y+7z+9}{7}[/tex]

Step-by-step explanation:

[tex]7x-7z-9=y[/tex]

[tex]7x-7z-9+7z=y+7z[/tex]

[tex]7x-9=y+7z[/tex]

[tex]7x-9+9=y+7z+9[/tex]

[tex]7x=y+7z+9[/tex]

[tex]\frac{7x}{7}=\frac{y}{7}+\frac{7z}{7}+\frac{9}{7}[/tex]

[tex]x=\frac{y+7z+9}{7}[/tex]

Answer:

13.89 to 2 dec places.

Step-by-step explanation:

a7 / a5 = r^2   where r is the common ratio.

So 3/5 = r^2

r^2 = 0.6

r = +√0.6

r = 0.7746.

The first term is a5 / r^4

= 5 / (0.7746)^4

= 13.89.

Answer:

31 pounds

Step-by-step explanation:

From the information given, you can write the following formula to calculate the total cost of sending gifts:

Total cost of sending gifts=2.50+0.85x, where x is the weight of the gifts in pounds

Also, you know that the total cost of sending gifts is $28.85 and you can replace this value and solve for x:

28.85=2.50+0.85x

28.85-2.50=0.85x

26.35=0.85x

x=26.35/0.85

x=31

According to this, the answer is that the gifts weighed 31 pounds.

Answer:

difference between linear equations and inequalities is the solution set. A linear equation of two variables can have more than one solution. For instance, with x = 2_y_ + 3, (5, 1), then (3, 0) and (1, -1)

Step-by-step explanation:

Answer:

In algebra, it is easy to find the third value when two values are given. Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side.

Homework #1-18: Answer yes or no, if no give the reason

1) Is A ⊆ B given A = silver, B = {gold, silver, diamond}

A is not a set, so it can’t be a proper subset.

Answer: no, because A is not a set

3) Is C ⊆ D given C = {Phoenix}, D = {Phoenix, Glendale, Peoria, Scottsdale}

I need two rules to work.

C is a set so rule 1 is satisfied.

Every element of C is also an element of D, so rule 2 is satisfied.

Answer: yes

5) Is A ⊆ B given A = {2,3} , B = {1,2,3,4,5}

I need two rules to work.

A is a set so rule 1 is satisfied.

Every element of A is also an element of B, so rule 2 is satisfied.

Answer: yes

7) Is A ⊆ B given A = a, B = {| }

A is not a set, so it can’t be a proper subset.

Answer: no, because A is not a set

9) Is A ⊆ B given A = { }, B = {1,2,3,4,5}

Answer yes: the empty set is a subset of every set.

11) Is S ⊂ T given, S= ∅, T = {1,2,3,4,5}

Answer yes: the empty set is a subset of every set.

13) Is A ⊂ B given A = {1,2,3}, B = {3,2,1}

This is not a true statement. The sets are equal and this symbol does not allow sets to be equal.

Answer: no, sets are equal

15) Is C ⊂ D given C = {1,2,3,4,5}, D = {1,2,3,4}

Answer: no, C is not contained in D, so this is not true

17) Is A ⊂ B given A = {4,3,2,1 }, B = {1,2,3,4,5}

A is a set so rule 1 is satisfied,

A is contained in B so rule 2 is satisfied

A is not equal to B so rule 3 is satisfied

Answer: yes (all 3 rules are satisfied)

Homework #19 – 34: Determine which of these are true. (Choose every answer that is true, in

many instances there will be more than one correct choice.)

A = B, A ⊆ B, B ⊆ A, A ⊂ B, B ⊂ A, or none of these

19) A = {Trix, Captain Crunch, Rice Krispees} B = {Rice Krispees}

B is contained, but not equal to A. B is both a subset and a proper subset of A.

A is not contained in B

The sets are not equal.

Answer: B ⊆ A, B ⊂ A

∠ 2 and ∠ 6 are corresponding angles and congruent, that is

∠ 6 = 112°

∠ 7 and ∠ 6 are vertical angles and congruent, thus

∠ 7 = 112°

Answer: 5/153

Step-by-step explanation:

Well, you'd just have to plug in 40 for n.

5/(40*4 - 7) = m

5/(160-7) = m

5/153 = m

An equation is formed of two equal expressions. As per the literal equation m=5/4n-7, the value of m when the value of n is 7 is 42.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The value of m from the given equation can be found by substituting the value of n as 7 in the given equation as shown below.

m = (5/4)n - 7

Substitute the value of n as 40,

m = (5/4)40 - 7

m = (5/1)10 - 7

m = 50 - 7

m = 42

Hence, as per the literal equation m=5/4n-7, the value of m when the value of n is 7 is 42.
