X is equal 3. What's c?<br> 6x-2(x-c)=10

Lisa [10]

Answer

C = -1

Step-by-step explanation:

substitute

6(3)-2(3-c)=10

18-6+2c=10

12+2c=10

12-12+2c=10-12

2c=-2

c=-1

2. 93.34 ÷ E = 18.69

blagie [28]

For 2, work backwards. 93.34 divided by 18.69 equals what? That’s your E.
3, use multiplication. 4.30 times 8.60 equals your D.
4, you just do as the problem says.
5, you do the same as number 2.
6, you do the same as 3.

For the word problem, say how someone starts off with 51.15 and has to give that something to 5 people.

Write the equation of a line parallel to the line 2x + y = 3 that passes through the point (2,6)

Lady bird [3.3K]

Answer <u>(assuming it can be in slope-intercept form)</u>:

$y = -2x +10$

Step-by-step explanation:

1) First, we need to find the slope of the given equation. To do that easily, convert it to slope-intercept form, represented by the formula $y = mx + b$ . Isolate y:

$2x + y = 3\\y = -2x + 3$

The number in place of $m$ , or the coefficient of the x-term, represents the slope of the equation. So, the slope of the given equation is -2.

Lines that are parallel share the same slope. So, the slope of the new equation will be -2 as well.

2) Now, remember that the slope-intercept form is represented by the formula $y = mx + b$ . In order to write an equation of a line using that formula, we need to substitute values for $m$ and $b$ . We know $m$ is the slope, so we already know what that equals. Now, we just need to find $b$ .

To do that, substitute -2 for $m$ in the slope-intercept formula. Additionally, substitute the x and y values of the point (2,6) for the x and y in the formula as well. This sets up the equation so that we can isolate $b$ and find its values:

$y = mx +b\\6 = (-2)(2)+b\\6 = -4 + b\\10 = b$

So, $b$ = 10.

3) Substitute values for $b$ and $m$ into the slope-intercept formula to write the slope-intercept form of the line:

$y = -2x +10$

At a little-known vacation spot, taxi fares are a bargain. A 28 -mile taxi ride takes 32 minutes and costs $22.40 You want t

Rzqust [24]

Answer: You need the unit price of how much it cost per min.

Step-by-step explanation:

First you have to find how much it costs for each min. So you divive 22.40 by 32 and you will get the answer for the cost of each min. Then Multiply the cost of each min by 38 and you should get the cost for 38 min.
