Answer:. $70
Step-by-step explanation: FROM the information provided, we can begin to determine an equation. Now the first sentence;
1)Let the number of $5 bills be X
2)The number of $1 bills will be 3 times x....., And that gives 3x
3)The number of $10 bills will be x-2 ( From the third sentence
Adding 1)+2)+3) we must have 18 as stated in the first sentence.
Consequently, we have;
x+3x+(x-2) = 18
Solving for x we get x=4.
Now substitution the value of X in the three equations.
1) 5 of $5 bills =$25
2) 15 of $1 bills = $15
3) 3 of $10 bills =$30
Adding, we have $70
Answer:
332 - 333, for nearest its 333
Step-by-step explanation:
Answer/Step-by-step explanation:
[1] x+9+1+3x
Add the numbers
x + 10 +3x
Combine like terms
4x+10
Common factor
2(2x+5)
<u>Solution = </u><u>2(2x+5)</u>
<u>.............................................................................................................................................</u>
[2] 5a+6c+2a+3c
Combine like terms
7a+6c+3c
Combine like terms
7a+9c
<u>Solution</u><u> = 7a + 9c</u>
<u>...............................................................................................................................................</u>
[3] 5n+6m+3n
Combine like terms
8n + 6m
Rearrange terms
6m + 8n
<u>Solution </u><u>= 6m+8n</u>

Let's assume
that number is x
now, we are given
The difference between nine times a number an 7 is -70
nine times of that number is 9x
so, we can set up equation
now, we can solve for x
so, number is -7.........Answer
13+13 (because there are two sides of one triangle that both equal 13) then with that answer multiply by 10 (because 10 is the base) and that is the area of one triangle, then multiply the area of one triangle by 2 (because there’s two triangles)
