The two numbers are 23 and 28

Step-by-step explanation:

We are given that

X = Y + 5\\and\\(X+Y) + 9 = 60\\X+Y = 51\\(Y+5) + Y = 51\\2Y + 5 = 51\\2Y = 46\\Y = 23\\\\X = Y + 5\\X = 23 + 5\\X = 28

sesenic [268]

Answer:

10

Step-by-step explanation:

40=2a<u>-3</u>+2a+3a<u>+1</u>

add like terms

  • 40=7a-2

get 'a' by its self

  • 40(+2)=7a<u>-2(+2)</u> [2 cancels out]
  • 42(÷7)=7a(÷7) [7 cancels out]
  • a=6

plug in the answer for Equations

  • biggest: 3(6)+1= 18+1= 19
  • smallest: 2(6)-3= 12-3=9

subtract smallest from biggest

  • 19-9=10

How do I solve: -(19-3s)-(8s+1)=35
bazaltina [42]
Hi Kimberly!

-(19 - 3s) - (8s + 1) = 35
-19 + 3s -8s - 1 = 35
-19 - 1 + 3s - 8s = 35
-20 - 5s = 35
-5s =35 + 20
-5s = 55
Divide both sides by -5
-5s/-5 = 55/-5
s = -11

A+ for Algebra guaranteed!
