Answer: X = -4
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
75,000 into scientific notation is 7.5 × 10^4
Y=2x
the slope is 2/1 and the y-intercept is 0
Answer:
a = 6
TV = 52
Step-by-step explanation:
TU + UV = TV
3a - 4 + 6a + 2 = 5a + 22
Add like terms in RHS
3a + 6a - 4 + 2 = 5a +22
9a - 2 = 5a + 22
Add 2 to both sides
9a = 5a + 22 + 2
9a = 5a + 24
Subtract 5a from both sides
9a - 5a = 5a + 24 - 5a
4a = 24
Divide both sides by 4
4a/4 = 24/4
a = 6
TV = 5a + 22
= 5*6 + 22
= 30 + 22
TV = 52
