Answer:
subtract 2a + 3b - 3b =5 - 3b
simply 2a = 5 -3b
divide both sides by 2 . 2a over 2 = 5 over 2 - 3b over 2
simply a= 5- 3b over 2

6. Pop's Cycle Shop sells bicycles and tricycles. The number of bicycles is 1 less than 5 times the number
of tricycles. All the bicycles and tricycles together have a total of 154 wheels. Find how many bicycles
and tricycles are there.
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Linear equations.
Let the number of bicycles = x
and number of tricycles = y
the relationship given is,
x = 5y-1
number of wheels of bicycle = 2x and of tricycles=3y
and other relation is, 2x+3y = 154
so now substituting we get as,
==> 2(5y-1) +3y= 154
10y-2+3y = 154
13y = 154+2
=> y = 12
=> 12*3 = 36 wheels of tricycles
so, 154-36 => 118 wheels of the bicycle.
so the number of bicycles = 118/2 = 59
hence,
==> number of bicycles = 59 and tricycles = 12
A bank account earns a fixed rate of interest compounded quarterly (every 3 months).
Determine whether each statement below is true regarding the value of the account. Select True or False for each statement.
True False
The value of the account increases at a constant rate over any unit time interval.
The value of the account increases at a constant percent rate per quarter.
The value of the account increases at a constant percent rate per year.
Answer:
false
true
false
Step-by-step explanation:
If an account earns a fixed rate of interest compounded quarterly, the value of the account increases every quarter.
If an account earns an interest that is continuously compounded, the value of the account increases at a constant rate over any unit time interval.
If an account earns an interest that is compounded yearly, the value of the account increases at a constant percent rate per year

2(4x - 2) = 8(x - 7)
Answer:
no solution
Step-by-step explanation:
2(4x - 2) = 8(x - 7)
8x - 4 = 8x - 56
0x = -52
no solution
Answer:
2(4x-2) = 8(x-7)
Distribute on both sides
2(4x)-2(2) = 8(x)-(7)(8)
Simplify
8x - 4 = 8x - 56
Subtract 8x from both sides to balance the equation.
-4 = -56
This is not equal.
Therefore the answer is no solution

A study of immunizations among school-age children in California found that some areas had rates of unvaccinated school-age children as high as 13.5%. Imagine a district in the state where 13.5% of children are unvaccinated. If three children are chosen randomly (assume they are not siblings) from this district, what is the probability that all three children have been vaccinated
Answer: 0.6472
Step-by-step explanation:
Given: The proportion of unvaccinated school-age children = 13.5%
Then, the proportion of vaccinated school-age children :p=100%-13.5%
= 86.5% = 0.865
Total children selected :n=3
Binomial probability formula:
[tex]P(X=x)=\ ^nC_xp^x(1-p)^{n-x}[/tex]
The probability that all three children have been vaccinated :
[tex]P(X=3)=\ ^3C_3(0.865)^3(0.135)^0\\=(1)(0.647214625)\approx0.6472[/tex]
Hence, the required probability = 0.6472

Is 16 a multiple of 8?
Answer:
have a good day!
Yes it is.
No one is answering please answer and explain I’ll mark brainliest
Answer:
M=x/7 let's say M is what Micheal earned, and so he earns x dollars every seven days
L=2(M)
L=2(x/7)Let's say L is what Lee earned, she earned twice as much as Micheal so 2(x/7)
Total=2(x/7)+x/7
Total=3(x/7) the total earnings is the sum of x/7 and 2x/7 is 3x/7

Hi there!
it would be 10.. if your asking for what multiply by 9 and 3 more than the number.
1.Find common multiply:
