X would equal 1 in this problem since 1+2=3 and the absolute value(s) in this equation would be -1+(-2)=3 since, a negative plus a negative equals a positive.
I hope this helped you!
6 - a =
(9a - 18)
First, simplify
to
/ Your problem should look like:
Second, multiply both sides by 3. / Your problem should look like:
Third, expand. / Your problem should look like:
Fourth, add 3a to both sides. / Your problem should look like:
Fifth, simplify 9a - 18 + 3a to 12a - 18. / Your problem should look like:
Sixth, add 18 to both sides. / Your problem should look like:
Seventh, add 18 + 18 to get 36. / Your problem should look like:
Eighth, divide both sides by 12. / Your problem should look like:
Ninth, since 3 goes into 12 to get 36, simplify
to 3. / Your problem should look like:
Tenth, switch sides. / Your problem should look like:
Answer:
a = 3 (one solution)
Answer:
C
Step-by-step explanation:
Two secants drawn to a circle from a common external point, then
The product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is
5(5 + x) = 4(4 + 10) = 4 × 14 = 56
25 + 5x = 56 ( subtract 25 from both sides )
5x = 31 ( divide both sides by 5 )
x = 6.2 → C
4(x+2) , 2(2x+4) , 8+4x , 1/2(8x+16) are all the same as 4x+ 8.
