Answer:
x° = 100°y° = 80°z° = 85°Step-by-step explanation:
The relations that you need to know to solve this are ...
vertical angles are congruentconsecutive interior angles are supplementary__
The angle marked x° and the one marked 100° are vertical angles, so have the same measure:
x° = 100°
__
The angle marked y° is supplementary to the one marked x°, so its value is ...
y° = 180° -100° = 80°
__
The two angles marked z° and (z+10)° are also supplementary, so ...
z° +z° +10° = 180°
2z° = 170°
z° = 85°

√(11 +4 √7)
hi, brainly helper please solve this ASAP. Thank
Answers
Given that: √{11 + 4√(7)}
Let √{11 + 4√(7)} = √(x) + √(y)
Squaring on both sides then
= [√{11 + 4√(7)}]² = {√(x) + √(y)}²
= 11 + 4√(7) = x + y + 2√(xy)
= 11 + 2√(7 * 2²) = x + y + 2√(xy)
= 11 + 2√(7 * 2*2) = x + y + 2√(xy)
= 11 + 2√(7 * 4) = x + y + 2√(xy)
= 11 + 2√(28) = x + y + 2√(xy)
On comparing with both sides, we notice that:
⇛x + y = 11 →→→→Eqn(1)⇛2√(xy) = 2√(28)
⇛ xy = 28
We know that
(x-y)² = (x+y)² - 4xy
(x-y)² = (11)² - 4(28)
(x-y)² = (11*11) - 112
(x-y)² = 121 - 112
(x-y)² = 9
x - y = √(9)
x - y = √(3*3)
Therefore, x - y = 3 →→→→Eqn(2)On adding equation (1) and equation (2), we get
x + y = 11
(+) x - y = 3

2x = 14
Shift the number 2 from LHS to RHS, changing it's sign.
⇛x = 14/2
⇛x = 7/1
Simplify the fraction to get the value of x.
Therefore, x = 7Now, substitute the value of x in equation (1) then
x + y = 11
⇛7 + y = 11
Shift the number 7 from LHS to RHS, changing it's sign.
⇛y = 11 - 7
Therefore, y = 4Now, we have: x = 7 and y = 4
So,
√(x) + √(y) = √(7) + √(4) = √(7) + √(2*2) √(7) + 2
(Or)
Short Method:√{11 + 4√(7)}
= √{11 + 2√(7*4)}
= √{11 + 2√(7)√(4)}
= √[{√(7)²} + {√(4)}² + 2√(7)√(4)
[since, (a+b)² = a² + 2ab + b²]
= √[{√(7) + √(4)}²]
= √(7) + √(4)
= √(7) + √(2*2)
Therefore, √{11 + 4√(7)} = √(7) + 2
Answer: Hence, the simplified form of √{11 + 4√(7)} is √(7) + 2

Match the graph with the correct set of equations for the linear system. Then, classify the system as Consistent and Dependent, Consistent and Independent, or Inconsistent. (You should have two answers selected)
Answers
Answer:
Consistent independent
x + y = 0 and -x + y = -8
Step-by-step explanation:
Inconsistent: parallel lines, no solutions
Consistent dependent: same line, infinite solutions
Consistent independent: intersects at one point, one solution
Therefore, the pair of lines are Consistent independent
From inspection of the diagram:
One line has a negative slope and the other a positive slope.
One has a y-intercept of 0 and the other a y-intercept of -8.
Therefore, the solution is x + y = 0 and -x + y = -8
Because:
x + y = 0 ⇒ y = -x (neg slope, y-intercept of 0)
-x + y = -8 ⇒ y = x - 8 (pos slope, y-interecept at -8)
josh sells 5 cycles in 2 days. after 20 days, how many cycles should be sold?
Answers
Answer:
50 cycles
Step-by-step explanation:
To find this out, we need to know how many cycles he sells a day. So as given he sells 5 cycles in 2 days, so what is half of five? While 2.5 cycles wouldn't make sense, lets use the variable to see what our answer would be approximately.
2.5 cycles x 20 days = 50 cycles.
So, in 20 days Josh would sell 50 cycles.
Answer:
50 cycles will be sold in 20 days
Step-by-step explanation:
2 days⇒5 cycles
1 day⇒5 divided by 2 days
20 days⇒5 cycles multiplied by 20 days divided by 2 days then the final answer is 50 cycles.

If the equation ar+b=cr + d has no solution, like in the example below, what must be true about a b c and d?
Answers
Answer:
See below.
Step-by-step explanation:
For an equation like [tex]\displaystyle \large{ar+b=cr+d}[/tex] to have no solution, the equation has to be false.
To make an equation false, we let a = c. That’d make a and c have same value, when we transport cr to subtract ar, we’ll get 0.
So if a = c, the equation is [tex]\displaystyle \large{b=d}[/tex] now that we have b = d. The equation has to be false to have no solutions, hence b and d must not equal to one another.
Summary
When a = c, the new equation is b = d as ar and cr having same value, when subtracted, the remain is 0+b=d.b = d means that the value of b and d are equal but that makes the solutions to be infinitely many. Therefore, we cannot let b = d.From second, b ≠ d.a = c but b ≠ dLet me know if you have any questions regarding this question or for clarification.
