Answer:
to start of in math you use stuff like numbers and equations although you can use equations in science in science you use different types of technology for that.
Answer:
13 trucks & 52 dolls
Step-by-step explanation:
Let number of trucks sold be t
and
number of dolls sold be d
Since dolls sold were 4 TIMES of trucks, we can write our 1st equation as:
d = 4t
Also, trucks cost 17 and dolls cost 24 and together they sold 1469, so we can write 2nd equation as:
17t + 24d = 1469
Putting 1st equation in 2nd one, we get an equation in "t" and lets solve for t:
17t + 24(4t) = 1469
17t +96t = 1469
113t = 1469
t = 1469/113 = 13
So, 13 trucks were sold
And, now we know d = 4t, so d = 4(13) = 52
So, 52 dolls were sold

Answer:
6. The number is 
7. The two numbers are
and 
Step-by-step explanation:
Question six can be re-worded to create the following expression:

Solve for x to find the number:

Question seven can be solved by first listing the constraints (assuming x is smaller than y):
- x and y are less than 20


To get the numbers, we can create a system of linear equations. First, solve for
in each expression:
