Answer:
The problem has a mistake in it. The mistake is found in line 3. The person who solved the problem subtracted 6 from both sides when they should have added 6.
x = 1
Step-by-step explanation:
4x-2=8-6x
10x-2=8
10x=10
x= 1
Answer:
50 coins
Step-by-step explanation:
We are given £1 worth of 20p coins.
Since it is known that,
£1 = 100p
i.e. £10 = 100 ×10 p = 1000p
As, we are taking 20p coins to get make the sum 1000p.
Thus, the number of 20p coins will be 
i.e. 50 coins
Hence, we get 50 coins to make £10 worth 20p coins.
Because the two triangles are similar, the angle of one letter would be the same for the corresponding angle of the other triangle.
In the given example R = L
S = M
T = N
Because M is given as 70 degrees, then S is also 70 degrees.
now you have R = 65 and S = 70
The three inside angles of a triangle equal 180, so to find T subtract R ans S from 180.
T = 180 - 65 - 70 = 45
T = 45 degrees.
Answer:
the shortest distance is the distance from a point to a line that make 90° .
so AC is the shortest distance.
<h3>step by step explanation</h3>
- then we have the find the distance between point A and C.
- to find that we use the distance formula .
d^2=(-3-1)^2 + (-3--1)^2
=(-4)^2 + (-2)^2
=16 + 4
=20
d=√20
this is the distance between point A and point C.
Answer:
x=30
y=22.5
Step-by-step explanation:
each of the corners are 90
3x=90
divide each side by 3
x=30
4y=90
divide each side by 4
x=22.5
