I need for this problem. Help please!​
Ray Of Light [21]

Answer:

⇒ x = 3.4975

Step-by-step explanation:

Assume cost of each figure = x

Given:

32x + 2.32 = 114.24

Find:

Value of x

Computation:

⇒ 32x + 2.32 = 114.24

⇒ 32x = 114.24 - 2.32

⇒ 32x = 111.92

⇒ x = 111.92 / 32

⇒ x = 3.4975

On a coordinate plane, a line goes through (negative 4, 0) and (4, negative 4). a point is at (2, 3). what is the equation of th
gayaneshka [121]

The equation of the line that is parallel and passes through the point (2,3) is; x +2y =8.

<h3>What is the equation of the line that passes through (2,3)?</h3>

If follows from the task content that the slope of the first line is; (-4-0)/(4-(-4)) = -1/2.

Hence, since the lines are parallel, they have the same slope and the equation of the second line is;

-1/2 = (y-3)/(x-2)

-x+2 = 2y -6

x +2y =8.

Pls help me!! I just need help on both of the following questions, a-d on each
Ymorist [56]
I'll do a and e on the first one to show you how to do it

Then See if you can do the rest

a. 6(-3)<span><span>
</span></span>
When your multiplying or dividing with negative numbers; If one of your numbers is negative like the one above, your answer will be negative

So 6 × 3 = 18 ; but since there is a negative on the 3 your answer will be -18

e. -20 ÷ 5

same for this; 20 ÷ 5 = 4, but since the 20 is negative the answer will be <span>-4

You do b, c, d, and f on the first question. Tell me what you get and we'll go from there

</span>Now for the second question <span>

</span>I will do a and d to show you how to do this then you do the rest<span> (I'm inserting a picture with these)

</span>a. 4(-2 \frac{1}{3}) + 7 \frac{1}{6}
First go ahead and turn the fractions into improper fractions, this makes them a bit easier to work with. When multiplying fractions; they do not need a common denominator, all you do is multiply top by top and bottom by bottom.<span>
However, when you add and subtract fractions you MUST have a common denominator

</span>d. (-4.25)(2) + (-4.25)(-2)
remember from the first problem a negative times a positive gives you a negative<span>

but when you times a negative by a negative you get a positive


Now you try b and c; let me know what you get, and we'll go from there!
