Answer:

x = 3

Step-by-step explanation:

<em>Given </em>

<em>4</em><em>(</em><em>5</em><em>x</em><em> </em><em>-</em><em> </em><em>3</em><em> </em><em>)</em><em> </em><em>=</em><em> </em><em>4</em><em>8</em>

<em>5x </em><em>-</em><em> </em><em>3</em><em> </em><em>=</em><em> </em><em>4</em><em>8</em><em> </em><em>/</em><em> </em><em>4</em>

<em>5x </em><em>-</em><em> </em><em>3</em><em> </em><em>=</em><em> </em><em>1</em><em>2</em>

<em>5x </em><em>=</em><em> </em><em>1</em><em>2</em><em> </em><em>+</em><em> </em><em>3</em>

<em>5x </em><em>=</em><em> </em><em>1</em><em>5</em>

<em>x </em><em>=</em><em> </em><em>1</em><em>5</em><em> </em><em>/</em><em> </em><em>5</em>

<em>x </em><em>=</em><em> </em><em>3</em>

<em>Therefore </em><em>x </em><em>=</em><em> </em><em>3</em>

Answer:

x=3

:)

First, DISTRIBUTE the 4 inside the parenthesis.

20x-12=48

then add 12 to both sides

20x=60

Now, divide by 20 on both sides.

x=3

Step-by-step explanation:

I can help lol, even though I never took eighth-grade math. I skipped from 6th-grade math to freshman-level math, wasn't fun- at all.

How to solve 2x+4 = 6x - 10
mars1129 [50]

Answer:

Step-by-step explanation:

2x + 4 = 6x - 10

Minus 2x on both sides

4 = 4x - 10

Add 10 on both sides

14 = 4x

Divide by 4 on both sides

14/4 = x

x = 14/4

Simplify fraction

x = 7/2 or x = 3 1/2

The sum of 23 consecutive integers is 2323. What is the largest of these 23 integers?
suter [353]
Sum of consecutive integers = n*(n+1) / 2
2,323 = (n^2 +n)/2
4,646 = n^2 + n
n^2 + n -4,646 =0
n = 67.663 which is NOT an integer

Given the system of inequalities: 4x – 5y &lt; 1 one-halfy – x &lt; 3 which shows the given inequalities in slope-intercept form
kkurt [141]

The slope- intercept is y> (1-4x) / 5 and y< 2x + 6

<h3 /><h3>What is inequality?</h3>

A  statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

Given:

4x – 5y < 1  and 1/2y – x < 3

Solving

4x – 5y < 1

-5y < 1- 4x

-y < (1-4x) / 5

y> (1-4x) / 5

Now, the second inequality,

1/2y – x < 3

1/2y< 3+x

y< 2x + 6

Under certain conditions, the average cost of driving a medium sedan in 2012 was 0.63 per mile. How much would it have cost to d
lions [1.4K]

The cost to drive such a car 12,000 miles in 2012 was 7560

<em><u>Explanation</u></em>

The average cost of driving a medium sedan in 2012 was 0.63 per mile.

Now for finding the total cost to drive such a car, we need to <u>multiply the 'cost per mile' by the 'total number of miles'</u>.

So, total cost to drive 12000 miles = 0.63*12000=7560
