Answer:
x = 11
Step-by-step explanation:
3/(3(2x-3)) = 2/(3x+5)
3(2x-3) = 6x - 9
3/(6x-9) = 2/(3x+5)
3(3x+5) = 2(6x-9)
9x + 15 = 12x - 18
12x - 9x = 15 + 18
3x = 33
x = 11
Answer:
20x + 10
Step-by-step explanation:
Given that :
Number of $20 bill = x
Number of $10 bill = 1
Total amount of money can be expressed as :
Σ(Value of bill * number of bill)
Hence,
($20 * x) + ($10 * 1)
20x + 10
The expression for the amount of money Donald has is : 20x + 10
Answer: -42
Step-by-step explanation:
-4(n-6)+m
and then they give you the values of each
basically what you do is put the value of m into where it shows on the equation as well as the n.
-4(-5-6)+2 and then you should get
-42
Answer:
2 1/18
Step-by-step explanation:
ok substitute w with 1/9
so the equation is now
1/2*1/9+2
Do multiplication first so,
1/2*1/9= 1/18
Now the equation should be
1/18+2
Finish it off by adding
1/18+2= 2 1/18
Answer:
Step-by-step explanation:
Side A is the longest side
Side B is half of A = A/2
Side C is 8m less than A = A-8
Perimeter of traingle = A+B+C
52 = A + A/2 + A-8
Collect like terms
52+8= A+A/2+A
60 = 5/2 A
Divide 60 by the coefficient of A
60÷5/2 = A
60×2/5= A
A=24m
Substitute the value of A into the expressions for sides B and C
Side B =A/2=24/2=12m
Side C =A-8=24-8=16m
The sides of the triangle are 24m, 12m and 16m
