From what I understand, we need to find x, y, and z.

We can easily find x by knowing a triangle has 180°.

Add 72+86=158 and then subtract 180-158 which gets you 22.

Now we have x=22°.

To find y, we first must find z. We can find z using the vertical angles theorem. This means x and z and the same, so z=22°.

Now, we can now find y by adding 70 and 22 = 92.

Subtract 180-92=88°.

All values have been found!

x=22°

y=88°

z=22°

You are not authorized to post a reply. A snail is at the bottom of a well 30 feet deep. It crawls up 3 feet each day, but at night, it slips down 2 feet. How long does it take for the snail to crawl out the well? 28 days. On the last day he would have reached the top and escaped before sliding down that night.

Answer:

2.55 minutes it takes a snail to crawl 85 inches

i hope this helps you

Answer:

Answer:

1092

Step-by-step explanation:

first calculate expense for each week;

25+30+40= 95

expense after saving

25-7= 18

30-7=23

40-7=33

18+23+33= 74

total saving for each week= 95-74=21

(you can also just do 7*3=21 to know total saving each week)

weeks in a year=

365 days/7= 52.14 = 52 weeks

total savings for the year= 52*21=$1092

Answer:

Step-by-step explanation:

There are 3 variables

Saving amount is

Total saving per week is

Saving per year considering 52 weeks per average year is:

Answer:

7 Apples

Step-by-step explanation:

For this question, we can write expressions for Maria's apples and Luigi's apples and form an equation as they end up with the same amount.

Mario starts with 12 apples but gives away x number. This means Mario's final amount of apples can be represented as: 12-x

Similarly Luigi starts with 26 and gives away 3 times the amount of Mario. So the number he gave away can be represented as: 3x (3 times the number Mario gave away). Therefore we can represent Luigi's final number as: 26-3x

Since they both end up with the same number of apples, we can put these expressions equal to each other in an equation to solve for x (the number of apples Mario gave away):

Mario             Luigi

12-x       =      26-3x

12-x=26-3x

Now we just need to move the unknowns to one side and the other terms to the other, combine and solve:

12-x-12=26-12-3x

-x=14-3x

-x+3x=14-3x+3x

2x=14

2x/2=14/2

x=7

Mario gave away 7 apples.

Hope this helped!

Answer:

8 use at least one zero That what they said in my math class I hope the answer right

[tex](x - 5)(x + 7) = 3 x + 21[/tex]

[tex](x - 5)(x + 7) = 3(x + 7)[/tex]

[tex](x - 5)(x + 7) - 3(x + 7) = 0 \\ [/tex]

[tex](x + 7)(x - 5 - 3) = 0[/tex]

[tex](x + 7)(x - 8) = 0[/tex]

[tex]x + 7 = 0 \\ x = - 7[/tex]

Or

[tex]x - 8 = 0 \\ x = 8[/tex]

Answer:

(28 - 11.5) ÷ 5.5

Step-by-step explanation:

So let's examine this question.

We have already payed $11.50 the rent the canoe, so we have $16.50. Divide that by $5.50, and you get 3. So, 3 hours.

Now for the expression.

You start out with $28. You subtract $11.50 from it because it is being used to rent the canoe. You then divide your answer by $5.50 to determine how many hours you can use the canoe for.

Hmm.

(28 - 11.5) ÷ 5.5 = h

(28 - 11.5) ÷ 5.5 = 3

Answer:

106

Step-by-step explanation:

ruff

123 dogs adoption in january

196 dogs adoption in July

Total adoption for the year = 123 + 196

= 319 adoptions

barks

78 dogs adoption in January

135 adoption in July

Total s like adoption for the year = 78 + 135

= 213 adoptions

Difference in the number of dogs adoption at each shelter that year

= Ruff total adoption for the year - Bark's total adoption for the year

= 319 adoptions - 213 adoptions

= 106

The difference in the number of dogs adoption at each shelter that year is 106

the pattern is

multiplied by -5

so...

1500 *-5 = -7500

-7500*-5 = 37500

hope this helps

Answer:

-7500,37500 are next two numbers in the pattern

Answer:

-81.42 is a rational number

Step-by-step explanation:

[tex] - 81.42 \\ \\ = - \frac{8142}{100} \\ \\ = - \frac{8142 \div 2}{100 \div 2} \\ \\ = - \frac{4071}{50} \\ \\[/tex]

Answer: It is a rational number.

A rational number is a number that can be represented as a fraction.

The fraction can be: [tex]- \frac{4071}{50}[/tex] because:

[tex]-\frac{81.42}{100}[/tex] ÷ 2 = [tex]\frac{40.71}{50}[/tex]

The answer is yes, it is rational.
