Negative numbers are smaller than positive numbers
Answer:
B. a = 5
Step-by-step explanation:
3(a - 4) + 1 = 9 - a
Distribute the 3 into the parenthesis.
3a - 12 + 1 = 9 - a
Add -12 and 1.
3a - 11 = 9 - a
Add a to both sides.
4a - 11 = 9
Add 11 to both sides.
4a = 20
Divide both sides by 4.
a = 5.
Proof:
3(a - 4) + 1 = 9 - a
Substitute variable.
3(5 - 4) + 1 = 9 - 5
Subtract inside parenthesis.
3(1) + 1 = 9 - 5
Multiply 3 and 1.
3 + 1 = 9 - 5
Add 3 and 1.
4 = 9 - 5
Subtract 5 from 9.
4 = 4.
Solve for the two velocities:
with the current = 48/6 = 8 mph
against the current = 48/8 = 6 mph
bv= boat velocity in still water
cv = current velocity
A) bv -cv = 6mph
B) bv + cv = 8mph
Adding both equations
2 * bv = 14 mph
boat velocity = 7 mph
current velocity = 1 mph

Answer:
your answers are correct
Step-by-step explanation:
since all the interior angles of a triangle add up to 180 this problem is correct.
two congruent legs of a triangle means the triangle is isosceles. An isosceles triangle has base angles that measure the same, therefore a is 52.
To find b, do 180 minus the two base angles, 52, to find the solution.

Answer:
A. 1/36 B. 1
Step-by-step explanation:
A. if (6^2)x=1; 6^2=36
36x=1
x=1/36
B. If (6^0)x=1; 6^0=1
(1)x=1
x=1
