Answer:
0
Step-by-step explanation:
he got all of them wrong
The answer is 1.45 + 0.55x ≤ $35; x ≤ 61
x - a number of miles
T - the total amount
T ≤ $35
T = 1.45 + 0.55x
1.45 + 0.55x ≤ 35
0.55x ≤ 35 - 1.45
0.55x ≤ 33.55
x ≤ 33.55 : 0.55
x ≤ 61 miles
the slope is y = 7/8x - 0.5 im pretty sure
Answer:
1449/2691
Step-by-step explanation:
We must start from the fraction that is 7/13. Now, we know that it was simplified, with trial and error we can reach the result.
First, let's multiply both by 200:
7 * 200 = 1400
13 * 200 = 2600
1400 + 2600 = 4000
It means that we are missing 140, to reach the objective, that is, we are close, let's try 205 now:
7 * 205 = 1435
13 * 205 = 2665
1435 + 2665 = 4100
We get even closer, only 40 missing, let's try 207 below:
7 * 205 = 1449
13 * 205 = 2691
1449 + 2691 = 4140
We managed to get to the corresponding numbers, therefore the original fraction was 1449/2691
