4 0

Answer: a=1

Step-by-step explanation:

-8(a-4)+3a=2(4a+9)+1          given

-8a+32+3a=8a+18+1            distribute

+8a             +8a

32+3a=16a+18+1                  subtraction property of equality

    -3a  -3a

32=13a+18+1                         addition property of equality

32=13a+19                             add like terms

-19        -19

13=13a                                    addition property of equality

÷13 ÷13

1=a                                          multiplication property of equality

a=1 is the answer. Hope this helps!

Midpoint between 105 and 115
Black_prince [1.1K]

Answer:

110

Step-by-step explanation:

Subtract the greater value (115) by the smaller value (105) and this gives you the answer 10. So the distance between the two values is 10. Divide this by 2 to find the midpoint, and you get 5. You can either add 5 to the smaller value, or subtract 5 from the bigger value, either way you would get the answer of 110.

What is the answer to this
arlik [135]

S\frac{O}{H} C\frac{A}{H} T\frac{O}{A} or Sin\frac{Opposite}{Hypotenuse}Cos\frac{Adjacent}{Hypotenuse} Tan\frac{Opposite}{Adjacent}


At the point/angle E:

- the adjacent side(side <u>next to</u> the point/angle) is ED

- the opposite side(side of the triangle <u>across</u> from the point/angle) is DF

- the hypotenuse (the<u> longest side</u> of the triangle) is EF.


sin ∠E = \frac{opposite}{hypotenuse}

sin ∠E = \frac{6}{10} = \frac{3}{5} (simplified)
