Answer:
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.
Step-by-step explanation:
Given the following equation:
The steps to solve it are:
5(x-3)+7(x+4)-73
1. Apply the Distributive property:
5x-15+7x+28=73
2. Add the like terms:
12x+13=73
3. Subtract5 13 from both sides of the equation:
12x+13-(13)=73-(13
12x=60
4. Divide both sides of the equation by 12:
12r/12 = 60/12
x = 5
To verify it, let's substitute into the equation:
5(5-3)+7(5+4)=73
Evaluating, we get:
5(2)+7(9)=73
10+63=73
73=73
Based on this, we can determine that Sarita's solution is correct, but she made an error in her verification (Observe that 5-3 is not equal to -2 )
Answer:
The correct opion is;
7 ≤ p
Step-by-step explanation:
The number of signatures Devin needs to collect = 1,000 signatures
The numer of signatures Devin has already = 380 signatures
The number ofsignatures each petition page can hold = 80 signatures
Therefore;
The number of extra signatures required = 1,000 - 380 = 680 signatures
The number of petition pages required = 1,000 petitions /(80 signatures/page) = 12.5 pages
The number of pages already filled = 380 petitions /(80 signatures/page) = 4.75 pages
The number of pages remaining, p = 12.5 - 4.75 = 7.75 pages
Therefore, 7 ≤ p.
Answer:
x = 18
Step-by-step explanation:
7x - 24 is a verticasl angle with an angle that is an...
Alternate interior angle with the combines values of 49 and 3x so they are equal
49 + 3x = (7x -23)
72 = 4x
x = 18
