Sarita showed the steps to solving the equation. 5 (x minus 3) + 7 (x + 4) = 73 Steps Sarita’s Solution Sarita’s Verification 1 5 x minus 15 + 7 x + 28 = 73 5 (5 minus 3) + 7 (5 + 4) = 73. 5 (negative 2) + 7 (9) = 73. Negative 10 + 63 = 73. 53 not-equal-to 73. 2 (5 + 7) x + (negative 15 + 28) = 73 3 12 x + 13 = 73 4 12 x + 60 5 x = 5 When Sarita tried to verify her answer, she found it was wrong. Which explains her mistake? Sarita’s solution is correct. She made an error in her verification. Sarita was supposed to add the 5 and 7 in the first step. Sarita added +13 instead of Negative 13 in the fourth step. Sarita was supposed to use the division property of equality in the third step.

Answer: First option.
Step-by-step explanation:
The complete exercise is attached.
Given the following equation:
The steps to solve it are:
1. Apply the Distributive property:
2. Add the like terms:
3. Subtract5 13 from both sides of the equation:
4. Divide both sides of the equation by 12:
To verify it, let's substitute into the equation:
Evaluating, we get:
Based on this, we can determine that Sarita's solution is correct, but she made an error in her verification (Observe that )

150(100)= 1.50
Now multiply 1.50(66)= 99
we can solve this problem by the rule of three.
Therefore:
66------------------------100%
x--------------------------150%
x=(66 * 150%) / 100%=99
Answer 150% of 66 is 99.
Other method:
150% of 66=1.5 *66=99
Answer: 150% of 66 is 99.
Answers
in order to solve this problem, you need both fractions to have the same denominators.
ask yourself if 3 can go into 9. it can.
you change the denominator of 3 to 9. but when you change the denominator, you also have to change the numerator. since 3 goes into 9 three times, you also multiply the numerator by 3.
1/3 times 3/3 equal 3/9. since 3/9 and 3/9 are the same, they are equivalent

Answer:
x=4
Step-by-step explanation:
3(2x+10)=54
6x+30=54
6x=24
x=4
Answer: 4
Step-by-step explanation:3(2x+10)=54
Multiply 3 to both numbers which would be 6x+30=54
Then, move 30 to the other side and that would be 6x=54-30
Subtract: 24 would be the answer
At last, you would divide 24 by 6
Just like this
x=24/6
Final answer would be
x=4

Final answer:
The drivers in the race at Talladega Superspeedway cover a distance of approximately 803.63 kilometers in a 188-lap race.
Explanation:
The total distance covered in the race in miles can be computed by multiplying the length of a single track (2.66 miles) by the number of laps (188 laps). That gives 499.68 miles. This value is then converted to kilometers by using the fact that 1 mile is approximately equal to 1.60934 kilometers. Therefore the total distance in kilometers is computed as 499.68 miles * 1.60934 km/mile which is approximately 803.63 kilometers.
To convert miles to kilometers, we can use the conversion factor 1 mile = 1.60934 kilometers. Therefore, the total distance covered in one race at Talladega Superspeedway is 2.66 miles x 1.60934 kilometers/mile = 4.28 kilometers. Since the race is 188 laps long, we can multiply the distance covered in one lap by 188 to find the total distance covered in one race. So, the drivers cover a total of 4.28 kilometers/lap x 188 laps = 805.04 kilometers in one race.
