Answer:
28451= 20000+8000+400+50+1
value of 8 =8000
Step-by-step explanation:
Percent means parts out of 100
40%=40/100=0.4
'of' means multply
40% of a number is 56
0.4 times a number=56
divide oth sides by 0.4
a number=140
original=140
Answer:
x= -1
Step-by-step explanation:
1. First, you need to combine like terms. Constants with constants and variables with variables. Since there is only one variable, there is nothing to combine it with so nothing happens to it. The constants, on the other hand, can combine.
2. You have to subtract 28 from 28 and 14 so that +28 can cancel out on the left side and combine on the right.
3. That will leave you with 14x= -14.
4. Now you need to get x on its own so you need to divide 14 (opposite of multiplication to cancel out) on both sides.
5. That will leave you with x= -1. That is your final answer.

The length of GH is 15.
<h3>How to calculate the length?</h3>
GH = IG
GH = 5x - 10
IG = 3x
5x - 10 = 3x
5x - 3x = 10
2x = 10
x = 10/2 = 5
GH = 5x - 10
= 5 * 5 - 10 = 25 - 10
GH = 15
<ABD = < DBC
<ABD = 10y°
<DBC = (8y + 4)°
10y° = (8y + 4)°
10y = 8y + 4
10y - 8y = 4
2y = 4
y = 4/2 = 2
The value of y is 2
<DBE = <DBC + <CBE
<DBC = 10y°
<CBE = <DBC = 10y°
y = 2
<DBC = <CBE = 10y° = 10*2° = 20°
<DBE = 20° + 20° = 40°
