Answer:
x = 90
Step-by-step explanation:
9x + 80 = 890 ( subtract 80 from both sides )
9x = 810 ( divide both sides by 9 )
x = 90

find the sum. 2/5 + 1/2
Answer:
9/10 NINE OVER 10
Step-by-step explanation:
To add two fractions they must be over a common denominator, which for this problem is 10. To put each fraction over a common denominator we must multiply each fraction by the appropriate form of 1. 2/5 + 1/2 ( 2/2 X 2/5 ) + (5/5 X 1/2 ) --> 4/10 + 5/10
We can now add the numerators of the two fractions over the common denominator: 4/10 + 5/10 ---> 4+5/10 ---> 9/10.
Hope this helps! I know what does though, marking me brainliest.
If Ill m, solve for x and y.
(7x -23)
49°
(3x)
(11y – 1)
Answer:
[tex] x = 18 [/tex]
[tex] y = 5 [/tex]
Step-by-step explanation:
49° + (3x)° = (7x - 23)° (corresponding angles)
[tex] 49 + 3x = 7x - 23 [/tex]
Collect like terms
[tex] 49 + 23 = 7x - 3x [/tex]
[tex] 72 = 4x [/tex]
Divide both sides by 4
[tex] \frac{72}{4} = x [/tex]
[tex] 18 = x [/tex]
[tex] x = 18 [/tex]
(3x)° = (11y - 1)° (corresponding angles)
Plug in the value of x and solve for y
[tex] 3(18) = 11y - 1 [/tex]
[tex] 54 = 11y - 1 [/tex]
Add 1 to both sides
[tex] 54 + 1 = 11y [/tex]
[tex] 55 = 11y [/tex]
Divide both sides by 11
[tex] \frac{55}{11} = y [/tex]
[tex] 5 = y [/tex]
[tex] y = 5 [/tex]

What will be the value of y?
Answer:
The answer is 40.
Step-by-step explanation:
Both of the angles given are congruent. 2y-10=70. To get y, you must multiply 2 and 40 together, making 80. Then you subtract it by 10, making it 70 degrees.

Ed's class took a field trip to the art museum. They left school at 10:45 A.M. It took them 15 minutes to drive to the museum. They stayed at the museum for 1 hour and 45 minutes. What time was it when Ed's class left the museum?
RAVEL Four members of the Kaplan family will take a river trip down the Colorado River in Colorado State Park. The rafting company charges $10 per day to rent the raft and $15 per person for a half-day river trip, or $100 flat rate for a half-day river trip. The raft can hold up to 10 people. A. How much will the trip cost the Kaplan family at the per person rate? B. How many people must be on the river trip to make the flat rate less expensive than the per person rate?
Answer:
(a) $16.25
(b) 7
Step-by-step explanation:
Rent of 1 raft for 1 day= $10
So, rent for 1 raft for half-day=10/2=$5
Charge for 1 person for half-day river trip =$15
Flat rate for half-day river trip=$200
(a) There is 4 member of the Kaplan on the trip.
One raft can hold up to 10 people, so, they need to take 1 raft on rent.
Rent of 1 raft for half-day =$5
Charge for 4 persons for half-day river trip =$15x4=$60
Total cost for the half-day trip for 4 persons=5+60=$65
Cost for half-day trip for 1 person= $65/4=$16.25
(B) Let there are n peoples on the river trip.
For the number of people up to 10, they need to take one boat on rent.
Total per person cost=(Cost for rent of 1 boat for half-day)+( Cost for half-day river trip)
=5+15n.
Cost for flat rate= (Cost for rent of 1 boat for half-day)+( Flat rate cost)
=5+100
The condition for which the flat-rate cost is less expensive than the per person rate cost is
[tex]5+100<5+15n[/tex]
[tex]\Rightarrow 100<15n[/tex]
[tex]\Rightarrow n>\frac{100}{15}[/tex]
[tex]\Rightarrow n>6\frac{2}{3}[/tex]
As n is the number od person which cant be a fractional value, so
n=7,8,9,... or [tex]n\geq7[/tex]
So, a minimum of 7 people must be on the river trip to make the flat rate less expensive than the per person rate.

The distance between two schools M and K is 2km. A market is situated between M and K . How far is the market from k ?
Answer:
1 km
Step-by-step explanation:
if the distance between M and K is 2 km and the store is situated exactly in the middle between M and K then the distance to the store from either M or K is half the distance between the two points M and K and therefore 1 km

PLEASE HELP! WILL MARK BRAINLIEST - What is 2(n+1)?
Answer:
I hope that this helps... (2n-1)
Step-by-step explanation:
1)If n is a natural number, (2n-1) is an odd number for n greater or equal to 2 .
2) Is n is a whole the number the same thing applies but the range of n just has its vertex at -1.(Odd integer)
3)If n is any integer, then the range is all integers from -Infinity to +Infinity.(Odd integer)
4)If n is any complex number, n can be represented in the form of e^i thetha (Euler’s form) but nothing can b e commented on whether it is odd or even.
5)If n is any real number the range of this data can be from -Infinity to +Infinity, nothing can be commented on whether the number is odd or even.

45 can be 90 and 27 can be 108
27*2 is 54
27*3 is 81
27*4 is 108
Answer: 45 = 90
27 = 108
Step-by-step explanation: A multiple is the result of multiplying the number by any integer.
Multiply 45 by 2 and you get 90 which fits between 85 and 110.
Multiply 27 by 2, but it only reaches 54 which doesn’t fit. Multiply 27 by 3 and you get 81, which still doesn’t fit between 85 and 110. Lastly, try multiplying 27 by 4 which gives you 108. This fits between 85 and 110!
Hope this helps, feel free to ask any further questions.

John pays for a Disney annual pass each month. He was charged $150 as a down payment, and each month he pays $28. Create an equation to represent the total cost, y of his annual pass. What is the y-intercept?
A. Write the formula for the volume V of a prism where B is the area of the base and h is the height. V= b. Solve the formula for B. B= c. Use the new formula to find the area of the base of the prism. The area of the base of the prism is square inches.
Step-by-step explanation:
The question lacks the required diagram, find the diagram attached.
Volume of the pyramid V = BH where;
B is the base area
H is the height of the prism.
b) To solve for B, we will have to make B the subject of the formula from the equation in a;
From (a);
V = BH
Divide both sides by H
V/H = BH/H
V/H = B
B = V/H
c) Since we are not given the volume and height of the prism, we can as well use the following parameters;
Let us assume Volume of the prism = 175in³ and eight of the prism H = 5in
Substitute this values into the equation derived in (b)
B = 175in³/5in
Hence the area of the base of the prism is square inches is 35in²
