Answer:Bill gets £171
Step-by-step explanation:
Total Money shared = £399
The ratio of the amount Ann gets to bill gets is 2:9 Chloe and Dave get 2.5 times the amount Ann gets can be written as
Ann : Bill : Chloe : Dave
2 : 9 : 2.5 x Ann : 2.5 x Ann
Let the amount of money
Ann gets be x
so that Bill gets 4.5x
Chloe = 2.5x
Dave = 2.5x
So that the expression to calculate each amount gooten will be
x + 4.5x + 2.5x + 2.5x = 399
10.5x = 399
x = 399/10.5
x=38
Therefore, Ann gets = £38
Bill gets =4.5 x= 4.5 x £38 = £171
Chloe gets=2.5x =2.5 x £38 = £95
Dave gets=2.5x =2.5 x £38 = £95

Which table represents a linear function help ASAP!!!!!
Answer:
The last one.
Step-by-step explanation:
I think it's the last one because as x increases by one, y increases by a constant rate of 5. The others don't increase by a constant rate. (I don't know if this is right but I think it is!)
Pythagorean theorem :)
Answer:
A^2 + B^2 = C^2
Step-by-step explanation:
Your welcome!
Answer:
x = 13
Step-by-step explanation:
In order to solve this you need to know the Pythagorean theorem:
a^2 + b^2 = c^2
a - 1 side
b - 2nd side
c - hypoteneuse
Step 1: Find the missing side of the triangles
** Note both triangles are equal to each other as shown by the dashed line in both that signifies both sides are equal to each other, and the 90-degree angle there as well**
Solve:
17^2 + b^2 = 19^2
289 + b^2 = 361
361 - 289 = 72
√72 = √b^2
8.5 = b (approximately, to the tenth)
Step 2: Because both of the triangles are equal to each other, the missing side is equal to 8.5, but there are two of them, in order to determine x, you need to add both values together:
8.5 + 8.5 = 17
Then you subtract it from the base value: 31
31 - 17 = 13
Therefore, x = 13, as that is the remaining of the base.

find x, find jl . any help is deeply appreciated :) !
Answer:
6. x = 15
7. JL = 78
Step-by-step explanation:
6. 8x - 23 = ½(10x + 44) (midsegment theorem)
Multiply both sides by 2
2(8x - 23) = 10x + 44
16x - 46 = 10x + 44
Collect like terms
16x - 10x = 46 + 44
6x = 90
Divide both sides by 6
x = 90/6
x = 15
7. MN = 5x - 16
JL = 4x + 34
MN = ½(JL) (midsegment theorem)
5x - 16 = ½(4x + 34) (substitution)
2(5x - 16) = 4x + 34
10x - 32 = 4x + 34
Collect like terms
10x - 4x = 32 + 34
6x = 66
x = 66/6
x = 11
JL = 4x + 34
Plug in the value of x
JL = 4(11) + 34 = 44 + 34
JL = 78

Answer:
(-3, -1) first option
Step-by-step explanation:
Solve the system of equations below. Write your answer as an ordered pair
(x, y).
Solve:
{Y= -3x + 13
{Y= -2x + 1
Answer:
(12, -23)
Step-by-step explanation:
to find x, substitute the value of y into y
-2x+1=-3x+13
collecting like terms
-2x+3x=13-1
x=12
to find y substitute the value x=12 into any of the equation
y=-3x+13
y=-3(12) +13
y= -36+13
y=-23

1. Kenny is putting a brick border around his irregular shaped garden. Before installing the border, Kenny must
cut the bricks to fit the angles of the garden. Use the given measures to answer the question.
m&A = (2x + 20°
m&B= (4x - 5)
m&C = (3x + 15)°
m&D = (5x + 16)
me= (2x - 2)
What are the angle measures of each vertex of the garden? Show all calculations and work. Keep in mind that
the drawing may not be to scale.
Answer:
a=82
b=119
c=108
d=171
e=60
Step-by-step explanation:
since we can see the figure has 5 sides we can use the interior angle formula 180(n-2) and replace n for 5 getting 180(3) which woukd get us to 540. with this information we know that all the verticals have to equal 540 so we can add the equations together to get
16x+44=540 - subtract 44 from both sides to get x by itself
16x=496 - simplify
x=31
substitute x for 31 in the equations.

3/4(12a+8)=31.2 someone please help me solve this:)
Answer:
2.8
Step-by-step explanation:
31.2×4/3
12a+8 = 41.6
12a=33.6
a= 2.8
Answer:
answer is 2.8
Step-by-step explanation:
3/4=0.75
0.75x12=9
0.75x8=6
9a+6=31.2
subtract 6 from both sides
9a=25.2
divide both sides by 9
a=2.8

tan x(cot x- csc x)=
Answer:
1 - sec (x)
Step-by-step explanation:
Write the problem as a mathematical expression
tan (x) (cot(x)−csc(x)
Apply the distributive property
tan (x) cot(x) +tan (x) (−csc(x)
Rewrite in terms of sines and cosines, then cancel the common factors
1+tan (x) (−csc(x)
Then u get 1 - sec (x)
