2 nd angle=1x
3x+1x =180
4x =180
x = 180/ 4
x = 45
so first angle =3x x = 45
= 3×45
= 135 degree
2nd angle = 1x
=45 degree

4 - ( 2x - 2) + 3x = 4(x + 5) - 3(x-2)-10
Answers
Step-by-step explanation:
4 + x + 3x = 4 ( 5x ) - 3 ( x ) - 10
4 + x + 3x = 4 + 5x - 3 + x - 10
x + 3x + 5x + x = 4 + 4 - 3 - 10
10x = 21
10x % 10 = 21 % 10
x = 2,1

Ms. Johnson owns a cabinet business that installs cabinets in kitchens. Her employees can install 2/3 of a
kitchen cabinet set in 1/5 of an hour.
How many kitchen cabinet sets can be installed by her workers in 1 hour?
Express your answer as an improper fraction.
Answers
Answer:
10/3 of the cabinet
Step-by-step explanation:
Given data
We are given that in 1/5 hour they can install 2/3 kitchen cabinet
We want to find out how many of the kitchen cabinet they can install in one hour
Hence
in 1/5 hour they installed 2/3 cabinet
in 1 hour they will install x cabinet
cross multiply
x* 1/5= 2/3
divide both sides by 1/5
x= 2/3/1/5
x= 2/3*5/1
x= 10/3 of the cabinet

Theo starts with savings of £18. James starts with no savings.
Each week from now,
Theo will save £4.50 and James will save £4
In how many weeks will Theo and James have savings in the ratio 15:8 ?
(Simple way to work it out please)
Answers
Answer:
6 weeks
Step-by-step explanation:
Theo savings = 18 + 4.50x
James = 4x
where x = number of weeks
Theo : James = 15 : 8
18 + 4.50x : 4x = 15 : 8
(18 + 4.50x ) / 4x = 15 / 8
Cross multiply;
8 (18 + 4.50x) = 15 (4x)
144 + 36x = 60x
60x - 36x = 144
24x = 144
x = 144 / 24 = 6 weeks

Finding the distance between two distinct points on a plane is the same as finding the hypotenuse of a right triangle. From this perspective, the distance formula states that the distance of two distinct points on a plane is equal to the square root of the sum of the square of the rise and run.

Answer B: I'm also confused. If anyone else knows can you please help me also. Sorry for not answering B. I hope this helps though.
Step-by-step explanation:
Answer A:
V=1/3π 6^2 (7) Since 12 is a diameter you half it which is 6
V=1/3π 36(7)
V=1/3π 252
V= 252π/3
V=84π

1. The length of a rectangle is 4 meters less than
twice its width. The area of the rectangle is
70 m2. Find the dimensions of the rectangle.
Answers
Answer:
length is 10, width is 7
Step-by-step explanation:
Area of a rectangle = length * width = lw
Area is known to be 70
length = twice width - 4 = 2w-4 = l
width=w
so A = lw = (2w-4)w = 70
(2w-4)w=70
2w^2-4w=70
2w^2-4w-70=0, divide by 2
w^2 - 2w - 35 = 0, not sure how your class solves these, I see visually
(w-7)(w+5)=0
w=7 or w=-5, -5 makes no sense in the real world (negative length), so w=7
l = 2w-4 = 2(7)-4 = 14-4 = 10
