18. 0.796 + 13 = 13.796 (the 13 is a whole number, so just put it in front of the decimal)

19. 15.63 + 24.36 = 39.99 (1+2=3 ; 5+4=9 ; 6+3=9 ; 3+6=9)

20. 19.86 - 4.94 = 14.92

21. 82 - 67.18 = 15.18 (again, whole number, there's no decimals to subtract, so leave them be)

22. 14.39 - 12.16 = 2.23 (1-1=0 ; 4-2=2 ; 3-1=2 ; 9-6=3)

WILL GIVE BRAINLIEST! Determine the coordinates of the point on the straight line y=3x+1 that is equidistant from the origin and

Lesechka [4]

Answer:

Step-by-step explanation:

The distance between a point (x,y) and the point (-3,4) is

d1= $\sqrt{ (x+3)2+(y-4)2}$ .

The distance between a point (x,y) and the point (0,0) is

d2= $\sqrt{x2+y2}$ .

You know what y is from the equation of the line, so substitute that, set d1=d2, and solve for x.

12+16(5×10)÷20-2=<br><br>What is the answer ?

mrs_skeptik [129]

$\implies {\blue {\boxed {\boxed {\purple {\sf {50}}}}}}$

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}$

$12 + 16(5 \times 10) \div 20 - 2$

$= 12 + 16(50) \div 20 - 2$

$= 12 + \frac{800}{20} - 2$

$= 12 + 40 - 2$

$= 52 - 2$

$= 50$

There are 6 rotten mangoes and 24 good mangoes in a bag. What fraction of the mangoes is rotten?

dem82 [27]

$\sf \bf {\boxed {\mathbb {Given:}}}$

Total number of rotten mangoes in the bag = 6

Total number of good mangoes in the bag = 24

$\sf \bf {\boxed {\mathbb {To\:find:}}}$

Fraction of the rotten mangoes to the total mangoes.

$\sf \bf {\boxed {\mathbb {Solution:}}}$

$\implies {\blue {\boxed {\boxed {\purple {\sf { \frac{1}{5} }}}}}}$

$\sf \bf {\boxed {\mathbb {Step-by-step\:explanation :}}}$

Total number of mangoes in the bag = Total number of rotten mangoes + Total number of good mangoes

➺ $\:6 + 24$

➺ $\:30$

Now,

Fraction = $\frac{Total \: \: number \: \: of \: \: rotten \: \: mangoes}{Total \: \: number \: \: of \: \: mangoes}$

➺ $\: \frac{6}{30}$

➺ $\: \frac{1}{5}$

Therefore, the fraction of the rotten mangoes to the total mangoes is $\sf\pink{\frac{1}{5}}$ .
