Step-by-step explanation:
Answer:
4. x= 18
Step-by-step explanation:
We solve the problem like this:
Since 3 is proportional to 6 and 9 is proportional to x, we set up a proportion.
3/9 = 6/x
We then use cross-multiplication to solve for x.
Answer:
y = -4
Step-by-step explanation:
First, let's find the slope. Since the line is horizontal, it's slope has to be 0 (this is because slope = rise/run, there is no "rise" in a horizontal line therefore the slope is 0)
Now, we need to find the y-intercept. This is where the line intercepts the y-axis. Looking at the graph, the line intercepts the axis at (0,-4), therefore the y-intercept is -4.
The equation would be:
y=0x-4
y=-4
Answer:
36%
Step-by-step explanation:
line up $ and % data like this:
$2.79 represents 100%
$3.79 represents X%
cross multiply
X*2.79 = 3.79*100
divide both sides by 2.79
X= 3.79*100 / 2.79 ≈ 136%
so it increased 36%
Hello! I would love to help!
Okay, we know that Raphel has to pay 3,000 dollars in a certain amount of months. Let's let "m" represent the amount of months it will take him.
Now, if we know that he saves 340 dollars a month, we can multiply the unknown amount of months, "m" by 340 to find how many will get 3000.
Here's our equation:
340m = 3000
Alright let's solve for m.
Divide both sides by 340.
340m/340= m
3000/340=8.824
So know we know m= 8.824, or exactly 8.824 months to save 3000 dollars.
However, it is really hard to count 8.824 parts of a month. Let's round it to the nearest whole, nine.
So, that means your answer is 9 months!
Hope this helped! Comment if you have questions!
