Answer:
these two apply:
10x + 12 = 38 and
10x = 26
Step-by-step explanation:
7x+6+3x+6 = 38
10x + 12 = 38
10x = 26
x = 2.6
Jason runs the same distance each day. In one 7-day period he ran 40 1/4 miles. He knows that there is a proportional relationship between n, the number of days, and t, the total distance he runs. Tell whether each statement is True or False.
A. The relationship can be expressed as n=5.25t. True or False
B. The graph of the equation is a straight line through (0,0). True or False
C. The unit rate is 5.75. True or False
The answer is A
Answer:
I think the answer is 2.. I'm sorry if its incorrect.
Step-by-step explanation:
IF you are solving for d:
isolate the D, do the opposite of PEMDAS.
-d/6 + 12 = -7
(subtract 12 from both sides)
-d/6 + 12 (-12) = -7 (-12)
-d/6 = -19
(multiply 6 to both sides)
-d/6(6) = -19(6)
-d = -19(6)
-d = -144
-d/-1 = -144/-1
d = 144
hope this helps
