The equation is,
→ 9x - 7 = -7
Then the value of x will be,

→ x = 0 ÷ 9
→ [ x = 0 ]
Hence, the value of x is 0.

Finn is 4 years older than Jake. Five years ago, the sum of their ages was 48.
Answers
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

The endpoints of PQ are P(-3, 1) and Q(4, 25) Find the midpoint of PQ
Answers
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
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 +
Answers
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

The measure of angle 1 is (3x + 10)° In the measure of angle 4 is (4x - 15)°
What is the measure of angle 7?
Answers
∠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
