Answer:

Step-by-step explanation:

First, find x

set your formula up as 3x+5=6x-10, since AB and DC are the same length.

This means x = 5

Now substitute 5 for x in the line DA

4x-5

4 * 5 - 5 = 15

HELP PLEASEEE

djyliett [7]

Answer:

Exact circumference is $7\frac{49}{150}km$

Approximate circumference is $7.33 km$

Step-by-step explanation:

We are given;

The diameter of a circle as $2\frac{1}{3} km$

We are required to determine the exact and approximate circumference of the circle.

We know that the circumference of the circle is given by;
Circumference = πD, where D is the diameter

Taking π as 3.14

$Circumference=3.14 (2\frac{1}{3}km)$

$=7\frac{49}{150}km$

The exact circumference of the circle is $7\frac{49}{150}km$

$7\frac{49}{150}km=7.327 km\\ = 7.33 km (nearest hundredth)$

Thus, the approximate circumference of the circle is $7.33 km$

Rachel's chocolate bar is 43% cocoa. If the weight of the chocolate bar is 68 grams, how many grams of cocoa does it contain? Ro

Yanka [14]

Answer:

29.24 grams

Step-by-step explanation:

It is given that,

Rachel's chocolate bar is 43% cocoa

The weight of the chocolate bar is 68 grams

We need to find how many grams of cocoa does it contain. It means it will contain 43% of 68 grams. It can be solved as follows :

$C=\dfrac{43}{100}\times 68\\\\C=29.24\ \text{grams}$

Hence, it will have 29.24 grams of cocoa.

18) What value of x makes R(x) = 10

Illusion [34]

<h3>Two Answers: <u>x = 2 and x = 10</u></h3>

========================================================

Explanation:

Draw a horizontal line through 10 on the y axis. This is because R(x) = 10 is the same as y = 10. The output of the function is the y value.

See the diagram below.

The horizontal line crosses the parabola at two locations. From those points, draw a vertical line straight down to the x axis. Note how we land at x = 2 and x = 10. This means that R(2) = 10 and R(10) = 10.

Is 2(x - 6) = -35 equivalent to 2x = -23

rusak2 [61]

Yes, if you just distribute 2(x-6). Then you would have 2x-12 = -35 then add 12 to the -35 and your answer would be 2x = -23 and leads to them being equivalent.
