2x-10=44+8x
subtract 2x from each side
8x-2x=6x
now we have -10=44+6x
subtract 44 from both sides
-10-44=-54
now we have -54=6x
divide both sides by 6
-54/6=-9
so x=-9
Answer:
Step-by-step explanation:
From the given information:
The null hypothesis and the alternative hypothesis can be computed as:
(i.e. there is no difference between the SAT score for students in both locations)
(i.e. there is a difference between the SAT score for students in both locations)
The test statistics using the students' t-test for the two-samples; we have:
t = 2.06
degree of freedom = (
) -2
degree of freedom = (45+38) -2
degree of freedom = 81
Using the level of significance of 0.05
Since the test is two-tailed at the degree of freedom 81 and t = 2.06
The p-value = 0.0426
Decision rule: To reject 
if the p-value is less than the significance level
Conclusion: We reject the , thus, there is no sufficient evidence to conclude that there is a significant difference between the SAT math score for students in Pennsylvania and Ohio.
Your max amount for this is $20. Let's say x represents the number of gallons.
20 ≥ 3.2x
x = 6.25 gallons
If they're asking for integers or whole numbers, you'd round down to 6 because you only have enough money for 6 full gallons. If you rounded up to 7, you wouldn't be able to fill it up completely because then you'd be over your $20.00 budget for gas.
Answer: (1,4)
Step-by-step explanation:
2x - 3y = -10
y = 4x
2x - 3(4x) = -10
2x - 12x = -10
-10x = -10
x = 1
y = (4)(1)
y = 4
Double Check:
2(1) - (3x4) = -10
2-12 = -10
-10 = -10
