30 POINTS PLS HELP ASAP Given m = −10.

Which equation is true?

5m + 5 = −40

−42 + 3m = 72

m/2 + 21 = 15

m/10 + 4.7 = 3.7

m/10 + 4.7 = 3.7

Step-by-step explanation:

Given m = −10.

put the value of m = -10 in this equation

a) 5m + 5 = −40

5(-10) + 5 = -40

-50 + 5 = -40

-45 = -40

b) −42 + 3m = 72

-42 + 3(-10) = 72

-42 - 30 = 72

-72 = 72

c) m/2 + 21 = 15

(-10)/2 + 21 = 15

-5 + 21 = 15

16 = 15

d) m/10 + 4.7 = 3.7

-10/10 + 4.7 = 3.7

-1 + 4.7 = 3.7

3.7 = 3.7

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
