Part 1: $4x + 7 = 3(2x - 5)$

$4x+7=6x-15$

$7=6x-15-4x

$

$7=2x-15$

$7+15=2x$

$22=2x$

$22=2x / 2$

$x=11$

Part 2: Sam is not correct because <span>he messed up the second step. He added 2x on both sides to get 7x, instead he should have subtracted. </span>

Answer:

Step-by-step explanation:

If the first digit is half of the second, that means the second is 2 times the first

So let's solve this algebraically...

The first digit could be called <em>a</em>

The second digit would have to be 2 times a (2a)

We can call the 3rd digit b

Since the sum of the second and third digit is 10, the equation would be this..

2x + b = 10, which is the same as b = 10 - 2x

The fourth digit is this equation

2x + 1

So the four digits are...

x, 2x, 10-2x, 2x+1

They are all equal to 23, which means...

x + 2x + 10-2x + 2x +1 = 23

After simplifying...

3x + 11 = 23

3x = 23 - 11

Which means...

3x = 12, x = 4

After you plug all that back into the prior equation you should get

first digit = 4 second digit = 8 third digit = 2 fourth digit = 9

Thank me later :)

Jeremiah bought three gallons of ice cream and four containers of strawberries for $19.50. Gary bought five gallons of ice cream

Gennadij [26K]

Answer:

Cost of $1$ gallon of ice cream $=\$3.5$

Cost of $1$ container of strawberries $=\$2.25$

Step-by-step explanation:

Let cost of $1$ gallon ice cream $=\$x$

Let cost of $1$ container of strawberries $=\$y$

<u>Jeremiah's purchase</u>

Jeremiah bought $3$ gallon of ice cream

so total spend on ice cream = cost of $1$ gallon $\times$ total gallons

$=x\times3\\=3x$

Jeremiah bought $4$ container of strawberries

So total spend on = strawberries =cost pf $1$ container $\times$ total container

$=y\times4\\=4y$

Jeremiah's total expenditure $=\$19.50$

$3x+4y=19.50 .......(1)$

<u>Gary's purchase</u>

Gary bought $5$ gallons of ice cream

so total spend on ice cream = $5\times x=5x$

Gary bough $2$ containers of strawberries

so total spend on strawberries = $2\times y=2y$

Gary's total expenditure $=\$22$

$5x+2y=22.....(2)$

solve eqn(1) and eqn(2)

$3x+4y=19.50\\5x+2y=22$

multiply eqn(2) by (2) and eqn(2)-eqn(3)

$(10x-3x)+(4y-4y)=(44-19.50)\\\\7x=24.5\\\\x=\frac{24.5}{7}\\\\x=3.5$

Substitute in eqn(2)

$5\times3.5+2y=22\\\\2y=22-5\times3.5=22-17.5\\\\2y=4.5\\\\y=\frac{4.5}{2}\\\\y=2.25$

Cost of $1$ gallon of ice cream $=\$3.5$

Cost of $1$ container of strawberries $=\$2.25$
