Answer:

No

Step-by-step explanation:

10/18 does not equal 45/18

An example of a proportional number is:

4/5 and 8/10

Both numbers are multiplied by 2 making them proportional

10/18 and 45/18 are not proportional

Hope this helped :)

Alex wrote 103.903 in expanded form as 100+3 x 1+9 x 1/100 +3 x 1/1000. Explain his mistake then tell how to correct it.
Damm [24]
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

PLEASE HELP ME!!!!!!!
Viefleur [7K]

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

Write the equation of the line that passes through (3, 4) and (2, –1) in slope-intercept form.
Norma-Jean [14]
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

Each month, Lilian spends 1/3 of her salary, saves 3/8 of the remainder and shares the rest of her salary equally among her moth
Natalija [7]

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
