Answer:
1. proportional, 6
2. not proportional
Step-by-step explanation:
<u>Table 1</u>
Each y-value is 6 times the corresponding x-value, so the variables are proportional, and y = 6 times x.
<u>Table 2</u>
The ratios of y to x are 2, 4, 8, so are not the same. The values are not proportional.
Answer:
1,383
Step-by-step explanation:
15x11+(29x42)
165 + (1,218)
= 1,383
You need an answer to get x. like it needs to be
10x+44=100 or something in order to find x
Answer:
d(4)=?
where
d= distance
t= hours
In this Linear function given by the law d(t) = 12t +20 and the graph below. To find the d(4), means to find out how many miles she cycled in the instant 4 hours.
By this function, after a break , the instant t=0, she had already cycled 20 miles.
Let's calculate
d(4) = 12(4) +20
d(4) =48+20
d(4)= 68 miles
Step-by-step explanation:
If the digits are a, b and c, the number n is 100a+10b+c
Here are the equations:
a number equals fifteen times the sum of its digits:
100a+10b+c = 15(a+b+c)
if its digits are reversed, the resulting number exceeds n by 396:
100a+10b+c+396 = 100c+10b+a
the one’s digit is one larger than the sum of the other two:
a+b+1 = c
Solving it gives you a=1, b=3, c=5, the number is 135.
