done!
Answer: 9 13/28
Step-by-step explanation:
First turn your mixed numbers into improper fractions. 6 3/4 becomes 27/4 and 2 5/7 becomes 19/7. Now we need to make the denominators match. The least common multiple of 7 and 4 is 28. 27/4 becomes 189/28 and 19/7 becomes 76/28. We can now add these to get 265/28. This improper fraction can now be turned back into a mixed number. 28 will go into 265 evenly 9 times with 13 left over. Answer is 9 13/28

Answer:
19.25 miles
Step-by-step explanation:
Antoine's rate before lunch was ...
(5.25 mi)/(3 h) = 1.75 mi/h
Then his rate after lunch was ...
2×(1.75 mi/h) = 3.5 mi/h
The distance he hiked after lunch was ...
distance = speed × time
(4 h)×(3.5 mi/h) = 14 mi
The distance Antoine hiked is the total of his before-lunch distance and his after-lunch distance:
5.25 mi + 14 mi = 19.25 mi
Solve algebraically for all values of x:
- 4x^4 + 36x^3 - 80x2 = 0
Answers
Given:
The equation is
[tex]-4x^4+36x^3-80x^2=0[/tex]
To find:
The value of x.
Solution:
We have,
[tex]-4x^4+36x^3-80x^2=0[/tex]
It can be written as
[tex]-4x^2(x^2-9x+20)=0[/tex]
Splitting the middle term, we get
[tex]-4x^2(x^2-5x-4x+20)=0[/tex]
[tex]-4x^2(x(x-5)-4(x-5))=0[/tex]
[tex]-4x^2(x-5)(x-4)=0[/tex]
Using zero product property, we get
[tex]x^2=0,x-5=0,x-4=0[/tex]
[tex]x=0,x=5,x=4[/tex]
Therefore, the values of x are 0, 4 and 5.

Step-by-step explanation:
Start by simplifying the parentheses. (8.1+7.9)=16 and (25/5)=5. Next, distribute each x into the parentheses. You should now have 16x-5x. Since they share like terms, you can subtract them.

Answer:
x = 63°
y = 27°
Step-by-step explanation:
RECT is a rectangle.
By the property of interior angles of a polygon,
All interior angles of a rectangle measure 90°
m(∠RTC) = 90°
m(∠RTC) = m(∠RTE) + m(∠CTE) [Angle addition postulate]
x° + 27° = 90°
x = (90 - 27)°
x = 63°
Since, opposite sides of a rectangle are parallel and equal in measure,
RE║TC and TE is a transversal line,
m∠RET = m∠CTE [Alternate interior angles]
y = 27°

Malaya is standing directly between a 90 foot tall courthouse and a 54 foot tall bank.

What is the distance between the courthouse and the bank? Show all your work to get credit!
Answers
Answer:
106.36 ftStep-by-step explanation:
Let the distance from the point Malaya is standing to the courthouse be x and the distance to the bank is y
x + y is the distance between the courthouse and the bankThen we have:
x/90 = cot 72° ⇒ x = 90 cot 72° = 90*0.3249196962 = 29.24 ft (rounded)y/54 = cot 35° ⇒ y = 54 cot 35° = 54*1.4281480067 = 77.12 ft (rounded)x + y = 29.24 + 77.12 = 106.36 ftAnswer:
106.3ft
Step-by-step explanation:
x= tan72=90/x
x= 90/tan 72
x= 29.2
y= tan35=54/y
y= 54/tan35
y= 77.1
x+y= answer
29.2 + 77.1 = 106.3
ANSWER FOR A BRAINLIEST Solve the system of two variables by substitution
Answers
Answer:
Substitution is when you isolate a variable-
3) We can divide the first equation by 6 to get x+y=-1, then isolate to get y=-1-x. We plug this into the second equation to have 3x+(-1-x)=-13. We simplify and get 2x=-12 so x=-6. We plug this back into the first equation and get -6+y=-1 so y=5. So the answer as an ordered pair is (-6,5).
4) We can isolate the second equation to get x=2y+11. We substitute this into the first equation to have -7(2y+11)-2y=-13. We simplify and get -16y=64 so y=-4. We plug this back into the second equation and get x+8=11 so x=3. So the answer as an ordered pair is (3,-4).
