Answer:
n = 4
Step-by-step explanation:
Given
10n + 2 = 7n + 14
Collect terms in n on the left side and numbers on the right side
Subtract 7n from both sides
3n + 2 = 14 ( subtract 2 from both sides )
3n = 12 ( divide both sides by 3 )
n = 4

Answer:
dont know what the expressions are but imma just guess its doing scientific notation, 8.73 x 10^-11
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
2x ≥ 4
Divide by 2
2x/2 ≥ 4/2
x ≥ 2
-x+7<-6
Subtract 7 from each side
-x+7-7<-6-7
-x < -13
Divide each side by -1, remembering to flip the inequality
x > 13
y>-x+3
This is a line with slope -1 and y intercept 3
This is a dotted line since there is no equals sign and graph above
Answer:
<u>a = 13</u>
Step-by-step explanation:
We should know that: The sum of the interior angles of the triangle = 180°
Given the measure of the angles: (6a - 2) , (5a - 13) and (5a - 13)
So,
(6a - 2) + (5a - 13) + (5a - 13) = 180°
16 a - 28= 180 ⇒ Add 28 to both sides
16 a = 180 + 28 = 208 ⇒ Divide both sides by 16
a = 208/16 = 13
