Answer:the number of short sleeves shirt sold is 15
the number of long sleeves shirt sold is 5
Step-by-step explanation:
Let x represent the number of short sleeves shirt sold by the student council.
Let y represent the number of long sleeves shirt sold by the student council.
The student council sells short sleeves for $5 each and long sleeve for $6 each. They were sold for a total of $105. This means that
5x + 6y = 105 - - - - - - - - - -1
The total number of shirts sold is 20. This means that
x + y = 20
Substituting x = 20 - y into equation 1, it becomes
5(20 - y) + 6y = 105
100 - 5y + 6y = 105
- 5y + 6y = 105 - 100
y = 5
x = 20 - y = 20 - 5
x = 15
Hello!
In a really simple way, 3 times our answer is 19. We can just divide to find it.
19/3= 6 1/3
Anyway, it might be nice to solve the equation for b. If a=6, then b has to be 1/3, but let's check.
18+3b=19
3b=1
b=1/3
Therefore, a+b= 6 1/3
I hope this helps!
Answer:
Step-by-step explanation:
50 = x^2
To isolate x you need to do the opposite of an exponent, which would be square root.
![\sqrt{50} = x Next solve what the square root of 50 is[tex]5\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B50%7D%20%3D%20x%20%3C%2Fp%3E%3Cp%3ENext%20solve%20what%20the%20square%20root%20of%2050%20is%3C%2Fp%3E%3Cp%3E%5Btex%5D5%5Csqrt%7B2%7D)
= x
That is the exact form, in other words your answer, if teacher is looking for a decimal, it would be
7.07 = x
If u subtract 1,000 - 0000 it will equal 1,000
