Answer:
x = 13 ; x = 5
Step-by-step explanation:
The easiest related equation to get is simply solving for x:
a) x + 5 = 18
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 5 from both sides:
x + 5 (-5) = 18 (-5)
x = 18 - 5
x = 13*
b) 66x = 330
Isolate the variable, x. Divide 66 from both sides of the equation:
(66x)/66 = (330)/66
x = 330/66
x = 5*
*Note: An equation simply is a expression that has an equal sign. This means that as long as there is an equal sign, it counts as an equation.

Answer:
You can make 27 different 3 digit numbers
Step-by-step explanation:
Since we can use 3 different numbers this means that each of the 3 digits can be one of the 3 numbers (4,2,9). This means that there are 3 different values for the first digit, 3 different values for the second digit, and 3 different values for the third digit, which mean that we can make 3 x 3 x 3 different 3 digit numbers (we took the number of possible values for each digit and multiplied them together.
3 x 3 x 3 = 27
4 * 45 = 180
265 - 180 = 85
85/5 = 17

Question:Write an equation in Slope intercept form of the line that passes through the given points (-3,4) (1,4)
2 Answers:
1: y=x+4
2:
answer would be “y=4”
to find the answer: first you have to find the slope with the given points. (y2 - y1 / x2 - x1)
plug it in to get: (4-4 / 1- -3) = 0/4 = 0
this means the slope would be 0
if the y intercepts are the same then it usually indicates that the slope would be 0 and that the answer is the y intercept.. but if you don’t understand how to get slope-intercept using other coordinates then here’s how:
you can use point-slope formula (y-y1 = m (x-x1) in order to do this just plug in one of the coordinates. in this case an example of point-slope form would be:
y-4 = 0 (x - -3) or y-4 = 0(x-1)
it doesn’t matter which coordinates you use..
then solve the point slope for slope-intercept.
y-4 = 0(x-3) multiply 0 with x and -3
y-4 = 0x move -4 to the right by adding 4
y = 0x + 4 or y = 4 would be your answer!
Answer:
The y intercept should be 2 lower than the original equation
