A= 3 b=5 c=6 what is number 7 and 8? how do u do the work

7. 34

8. 75

I may be wrong, though I'm about 97% sure my work is correct. More than likely, if one of these are wrong it'll be 8, though I still doubt it is.

Step-by-step explanation:

A=3

B=5

C=6

7.

once you have the letters substituted, simply solve the equation.

using PEMDAS, you'll need to convert the exponents first.

now, the equation should look like this:

6(3)+25-9

Now, you multiply as M comes before A and S in PEMDAS

6(3)=18

18+25-9

Now, reading left to right, A will come before S so you will do the addition first.

18+25=43

Your equation should now look like this:

43-9

Now, simply solve the subtraction problem.

43-9=34.

therefor, 7 should be 34.

8.

substitute the letters for their number values first:

Now, solve the exponent next:

5 squared () is 25

Your problem should now look like this:

(3)(25)

Next, you simply multiply to get the following:

3x25=75

Therefor, question 8 should be 75.

step-by-step explanation:

u send me a picture of ur work

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
