Answer:
Shen served 32 orders, Aldo served 16 orders and Heather served 9 orders
Step-by-step explanation:
Let S represent Shen, A, Aldo and H, Heather
Now, let's interpret the question
Shen served 2 times as many as Aldo, this gives:
S = 2A ...eq 1
Aldo served 7 more orders than Heater
A = 7 + H ... eq 2
Slot in the value of A in eq 1
Therefore,
S = 2 (7 + H)
Expand the bracket
S = 14 + 2H
Shen, Heather and Aldo served a total of 57 orders
S + A + H = 57
Slot in the values of S and A
(14 + 2H) + (7 + H) + H = 57
14 + 2H + 7 + H + H = 57
Collect like terms
14 + 7 + 2H + H + H = 57
21 + 4H = 57
4H = 57 - 21
4H = 36
H = 9
Substitute the value of eq 2
A = 7 + H
A = 7 + 9
A = 16
Substitute the value of A in eq 1
S = 2A
S = 2(16)
S = 32
Therefore, Shen served 32 orders, Aldo served 16 orders and Heather served 9 orders

Step-by-step explanation:
Just implement x and solve for y.
Answer: To clear an equation of decimals, multiply each term on both sides by the power of ten that will make all the decimals whole numbers. In our example above, if we multiply .25 by 100, we will get 25, a whole number. Since each decimal only goes to the hundredths place, 100 will work for all three terms.
So let's multiply each term by 100 to clear the decimals:
(100)0.25x + (100)0.35 = (100)(-0.29)
25x + 35 = -29
Now we can solve the equation as normal:
25x + 35 - 35 = -29 - 35
25x = -64
x = -2.56 Since the original was in decimal form, the answer should most likely also be in decimal form.
Let's look at one more:
1.75x + 4 = 6.2
We have to think a little more carefully about what multiple of ten to use here. 6.2 only needs to be multiplied by 10, but 1.25 needs 100, so we will multiply every term by 100. Don't forget to multiply the 4 by 100 as well.
(100)(1.75x) + (100)(4) = (100)(6.2)
175x + 400 = 620
We had to be extra careful as we multiplied by 100. Now we can solve the equation as normal:
175x + 400 - 400 = 620 - 400
175x = 220
x = 1.26
