Answer: 20
Explanation:
(5x+40)+(5x+40)+(2x)+(2x)=360
10x+80+4x=360
14x+80=360
-80 -80
14x=280
/14 /14
x=20
Answer:
C. 7/16 is the answer
Step-by-step explanation:
0.7mi x 5/8 = 0.4375= <u>7/16</u>
<u>^0.7 is from the 7/10 mile to school</u>
Answer:
C. There is sufficient evidence to support the claim µ1 > µ2
Step-by-step explanation:
The null hypothesis in this case would be:
H0: µ1 = µ2.
And the alternative would be:
H1: µ1 > µ2.
Then if the null hypothesis is rejected, statistically both samples do not have an equal mean, you reject that µ1 = µ2. And so, you accept the alternative hypothesis: µ1 > µ2.
The correct answer is C.
Answer: x=0
Step-by-step explanation:
Multiply both sides of the equation by 35, the least common multiple of 5,7.
7×4x−5×3x=5×4x+5×5x
Multiply 7 and 4 to get 28.
28x−5×3x=5×4x+5×5x
Multiply −5 and 3 to get −15.
28x−15x=5×4x+5×5x
Combine 28x and −15x to get 13x.
13x=20x+25x
Combine 20x and 25x to get 45x.
13x=45x
Subtract 45x from both sides
13x−45x=0
Combine 13x and −45x to get −32x
−32x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since −32 is not equal to 0, x must be equal to 0.

16•10=(10+6)•10
=(160•10)+(160•10)
=1600+1600
