Answer:

The answer is 168!

Step-by-step explanation:

6*4=24 (There are two triangles so you don't have to divide by 2, 24 is simply the answer to both), 6*9=54, 5*9*2=90, 90+54+24=168! I hope this helps! Have a great rest of your day!

Answer:

A≈114.12

Step-by-step explanation:

A=2AB+(a+b+c)h   AB=s(s﹣a)(s﹣b)(s﹣c)

              s=a+b+c/2

                              A=ah+bh+ch+1

2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=9·5+6·5+4·5+1

2·﹣94+2·(9·6)2+2·(9·4)2﹣64+2·(6·4)2﹣44≈114.12459

Answer:

D, B, C, A

Step-by-step explanation:

Solve the equations by combining like terms, isolating the variable, and dividing the equation by the coefficient of the variable.

Doing this, the first equation should be 2, the second equation should be -2, the third equation should be -1, and the last equation should be -6.

Then, we can order them.

Your brother is 1313 your age. Your sister is 6 years older than your brother. Your sister is 10 years old. Write and solve an e
il63 [147K]

There seems to be a typo. You wrote 1313, but I'm assuming you meant to say the fraction 1/3. If this assumption is correct, then continue with the rest of the solution. If the assumption is not correct, then ignore what I wrote below and please provide clarification of what the "1313" should represent. Thank you.

----------------

B = your brother's age

S = your sister's age

Y = your age

All of these ages are current present day ages.

---------------

"your brother is 1/3 your age" so B = (1/3)Y or B = Y/3.

"Your sister is 6 years older than your brother" so S = B+6

"Your sister is 10 years old" so S = 10.

---------------

S = B+6

B+6 = S

B+6 = 10 ... plug in S = 10

B+6-6 = 10-6 ... subtract 6 from both sides

B = 4

Your brother is 4 years old.

---------------

B = Y/3

Y/3 = B

Y/3 = 4 .... plug in B = 4

3(Y/3) = 3*4 ... multiply both sides by 3

Y = 12

<h3>Answer: Your age is 12 years old.</h3>

note: This answer hinges on assumption that the "1313" should be "1/3".

Dominik [7]

Answer:

3. 2.5

4. $5 per candy bar

5. You mowed 6 lawns

6. 15.66 is the number

7. 13 weeks

8. 135 students came

9. 12

Step-by-step explanation:

3. 25+7= 32.

81/32= 2.5

4. 23-3= 20

20/4= 5

5. 155-35=120

120/20=6

6. 10-4 = 6

94/6=15.66

(not 100% sure about this one)

7. 200-161=39

39/3=13

8. 975-300=675

675/5=135

9. 36-12=24

36/3= 12

(not 100% sure about this one)

Bonus: Sorry I don't know

I hope I can help! Also next time do each question one by one so other people can answer and not answer all of them if they don't know one.
