Answer:
Step-by The scale factor is the ratio that determines the proportional relationship between the sides of similar figures. For the pairs of sides to be proportional to each other, they must have the same scale factor. In other words, similar figures have congruent angles and sides with the same scale factor.-step explanation:
Step-by-step explanation:
Remember to isolate the variable for each question. Note the equal sign, what you do to one side, you do to the other.
1) 4 + x = 8
Subtract 4 from both sides
4 (-4) + x = 8 (-4)
x = 8 - 4
x = 4
D) x = 4 is your answer
2) -2x ≤ 6
Note that when dividing or multiplying a negative number, you must flip the sign. Isolate the variable (x).
(-2x)/-2 ≤ (6)/-2
x ≥ 6/-2
x ≥ -3
A & B are the same, so you'll have to ask the teacher which one was supposed to have a negative 3
3) Remember to do the opposite of PEMDAS. First subtract, then multiply. Again, isolate the variable (x).
x/2 + 3 = 5
x/2 + 3 (-3) = 5 (-3)
x/2 = 5 - 3
x/2 = 2
(x/2)(2) = 2(2)
x = 2 * 2
x = 4
A) x = 4 is your answer
4) Remember to do the opposite of PEMDAS. First subtract, then divide. Again, isolate the variable (x).
7x + 6 = 20
7x + 6 (-6) = 20 (-6)
7x = 20 - 6
7x = 14
(7x)/7 = (14)/7
x = 14/7
x = 2
D) x = 2 is your answer
5) You are solving for x. Note that there are two variables, however, you don't need to worry too much about the second variable (<em>a</em>), just know that you cannot combine (using addition or subtraction) a number with variable and a constant (a number without).
First, subtract 8a from both sides:
2x + 8a (-8a) = 10 (-8a)
2x = 10 - 8a
Next, divide 2 from both sides to isolate the variable (x):
(2x)/2 = (10 - 8a)/2
x = (10)/2 (-8a)/2
x = 5 - 4a
D) x = 5 - 4a is your answer

Answer
Find out the how many orders did they each serve .
To prove
Let us assume that the tony served be = x
As given
Laura,Ahmad,and Tony served a total of 94 orders Monday at the school cafeteria.
Ahmad served 3 times as many orders as Tony. Laura served 9 more orders than Tony.
Let us assume that the Ahmad served be = 3x
Let us assume that the Laura served be = 9 + x
Than the equation becomes
x + 3x + 9 + x = 94
5x = 94 - 9
5x = 85
x = 17
Tony served order be = 17
Ahmad served order be = 3 × 17
= 51
Laura served order be = 9 + x
= 9 + 17
= 26
Therefore the Tony served order is 17 , Ahmad served order is 51 and
Laura served order is 26 .
The first eqaution is multiplying the first number by 5 then the next is multiplying the first number by 6 then 7 i believe the last one would be 8x8 which is 64
