Answer:Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.

The endpoints of PQ are P(-3, 1) and Q(4, 25) Find the midpoint of PQ
Answer:
(-1, 14.5)
Step-by-step explanation:
Well there is a mid-point formula that looks like this:
m = ((x1+x2)/2) , ((y1+y2)/2)
So if we input our two points into the formula we get this:
m=((-3+1)/2) , ((4+25)/2)
Which can be simplified to get:
m=(-1, 14.5)
So these are your coordinates

What is 9x-7=-7 ?????
Answer:
when we stop 9x then
7 will go another side so,.9x=7
and when X is stoppedbit will be=7/9
Answer:
[tex] \sf \: x = 0[/tex]
Step-by-step explanation:
Now we have to,
→ Find the required value of x.
The equation is,
→ 9x - 7 = -7
Then the value of x will be,
→ 9x - 7 = -7
→ 9x = -7 + 7
→ 9x = 0
→ x = 0 ÷ 9
→ [ x = 0 ]
Hence, the value of x is 0.

The median of a set of consecutive odd integers is 138. If the greatest integer in the set is 145, what is the least integer in the set?
Answer:
131
Step-by-step explanation:
Given that:
Median of a consecutive odd integers = 138
Greatest integer In dataset = 145
Least integer in dataset =
Since the integers are consecutive ;
Number of integers to greatest integer value : Greatest integer - median value = 145 - 138 = 7
Hence, 7 integers before the median value should give us the least integer value ;
138 - 7 = 131
CHECK:
131,132,133,134,135,136,137,138,139,140,141,142,143,144,145
Median = (n+1)/2 th term
Median = (15+1)/2 = 8th term = 138
Highest = 145
Least = 131
Answer:
131

The measure of angle 1 is (3x + 10)° In the measure of angle 4 is (4x - 15)°
What is the measure of angle 7?
∠1 = ∠4 ( vertically opposite angles )
Then :-
[tex]3x + 10 = 4x - 15[/tex]
[tex]10 = 4x - 15 - 3x[/tex]
[tex]10 = 1x - 15[/tex]
[tex]1x - 15 = 10[/tex]
[tex]1x = 10 + 15[/tex]
[tex]1x = 25[/tex]
Which means :-
∠1 =
= 3x + 10
= 3 × 25 + 10
= 75 + 10
= 85°
∠4 =
= 4x - 15
= 4 × 25 - 15
= 100 - 15
= 85°
Then :-
∠7 = ∠6
∠6 + ∠4 = 180° ( interior angles on the same side of transversal )
∠6 + 85 = 180°
∠6 = 180 - 85
∠6 = 95°
As ;
∠6 = ∠7
∠7 = 95°Therefore , angle 7 = 95° .Answer:
95

9/6 or 1 1/2
Step-by-step explanation:
For this problem. We need to add the following fractions:
2/3 and 5/6.
Let's find common denominators:
(Multiply 2/3 by 2/2)
= 4/6
Add the numerators:
[tex] \frac{4}{6} + \frac{5}{6} = \frac{9}{6} [/tex]
9/6 can also equal 1 1/2 as a simplified mixed fraction.
Do przygotowania jednej porcji gofrow potrzeba 1 i pul szklanki maki pszennej, 1i jedna trzecia szkalanki mleka oraz 0,5 szkalnki oleju pszennego. Szklanka maki wazy 16 dag, szklanka mleka-24 dag, a szklanka oleju-21,5 dag.Ile dekagramow waza lacznie skladniki potrzeba na jedna porcje gofrow?
Odpowiedź:
5,075 dekagramu
Wyjaśnienie krok po kroku:
Biorąc pod uwagę, że:
Na jedną porcję gofra:
mąka pszenna = 1 szklanka
mleko = 1 szklanka
olej pszeniczny = 0,5 szklanki
Waga na filiżankę:
1 szklanka mąki = 16 gramów
Szklanka mleka = 24 g
Dziewczęta oliwy = 21,5 g
Na jedną porcję gofra:
(1 * 16 gramów) + (1 * 24 gramów) + (0,5 * 21,5 gramów)
16 gramów + 24 gramów + 10,75 gramów
= 50,75 grama
Odwołanie :
1 gram = 0,1 dekagramu
50,75 gramów = (50,75 * 0,1)
= 5,075 dekagramu

Finn is 4 years older than Jake. Five years ago, the sum of their ages was 48.
Answer jake is 29
Step-by-step explanation:
Answer:
Step-by-step explanation:
let the age of Jake be=x
let the age of Finn be=x+4
Five years ago:
age of Jake +age of Finn=48
x+x+4-5=48
2x-1=48
2x=48=1
2x=49
x=49/2
x=24.5
therefore, age of Jake=x=24.5
therefore, age of Finn=x+4=24.5+4=28.5

Olivia has $150 to spend on clothes. She buys one pair of jeans for $38. She wants to buy several shirts that cost $21 each. Which inequality could be used to determine the possible number of shirts, x, she could buy? A. 38 21 150 x − C. (38 21) 150 x + B. 38 21 150 x+ D. 38 21 150 x +
Answer:
38+21x<=150Step-by-step explanation:
The options are not clearly stated, nevertheless, let us formulate the inequality.
The total amount at hand=$150
the cost of a pair of jean=$38
the cost of shirt is=$21
the cost of x shirts =$21x
the total expenses is
38+21x
Therefore the inequality is
38+21x<=150
