Let Carl's age be c and Ben's age be 3c.

Equation:

3c = 2c + 2

=> 3c - 2c = 2

=> c = 2

So, Carl is 2 years old.

0.45 plus 9x equals 27
oee [108]

Answer:

x = 2.95

Step-by-step explanation:

<u>Step 1:  Convert words into an expression</u>

0.45 plus 9x equals 27

0.45 + 9x = 27

<u>Step 2:  Solve for x</u>

0.45 + 9x - 0.45 = 27 - 0.45

9x / 9 = 26.55 / 9

x = 2.95

Answer:  x = 2.95

I can’t find the answer tried twice probably easy for others
Sloan [31]
Answer: y=-x-2

Slope intercept form is written as y=mx+b, with m being the slope and b being the y intercept.

The slope is negative one. To find the slope, use the formula y1-y2/x1-x2. When you substitute, you may get -4-1/2-(-3). When you solve it, you get -5/5, or -1.

To find the y intercept, look where the line crosses the y axis (vertical line). In the graph, it crosses as -2. Substitute these numbers into the equation and you get y=-1x-2 which can be simplified to y=-x-2.
