Your mistake was in this part 9 x 1/100 . After the decimal point the place value starts with tenths so you should write 9 x 1/10 .
Place values
Before the decimal
point
3 ones = 3 x 1
0 tens = 0 x 10
1 hundreds = 1 x 100
After the decimal
point
9 tenths = 9 x 1/10
0 hundredths = 0 x 1/100
3 thousandths= 3 x 1/1000
1 x 100 + 0 x 10 + 3 x 1 + 9 x 1/10 + 0 x 1/100 + 3 x 1/1000
100 + 0 + 3 + 0.9 + 0 + 0.003
100 + 3 +
0.9 + 0.003 = 103.903

Answer:
Angle DCB is Equal to 78
Step-by-step explanation:
4x+2 + 3x+3 =180
7x +5=180
7x=175
x=25.
Then put the x in the 3x+3
3(25) +3 = 78
so DCB = 78
Answer:
Step-by-step explanation:
x^2 + 2x = 6x+45
x^2 -4x -45 =0
x^2 - 5x +9x -45 =0
x(x-5) +9 (x-5)=0
(x-5)(x+9)=0
x = 5, -9
x = 5; measure of exterior angle = 5^2+2(5) = 35
x=-9; measure of exterior angle = (-9)^2 + 2(-9) = 63
First you have to find slope (m)
m = (y2 - y1) / (x2 - x1)
m = (-1 - 4) / (2 - 3)
m = (-5) / (-1)
m = 5
now you have to use point-slope
y - 4 = 5 (x - 3)
y - 4 = 5x - 15
y = 5x - 11 is your answer
Fraction left after spending = 1 - 1/3 = 2/3
Fraction saved = 3/8 x 2/3 = 1/4
Fraction left after saving = 2/3 - 1/4 = 5/12
Fraction shared with 3 people = 5/12 ÷ 3 = 5/12 x 1/3 = 5/36
Answer: 5/36
