Answer:
m - 9 = 3/5 m (Steve has some money. After spending $9, he now has 3/5 of his original amount)
So it's just the matter of isolating m. Subtract m from both sides:
-9 = -2/5 m
Now you just need to multiply both sides by -5/2 to get your final answer.
Step-by-step explanation:
Answer:
Slope = 1/2
y-intercept = 30
Equation : y = 1/2x + 30
D. 150 miles
Step-by-step explanation:
We can use the two visible points you marked on the graph.
They are (0,30) which is also the y-intercept and (20,40).
Calculate change of y over change of x.
10/20 or 1/2
So the slope is 1/2 and the y-intercept is 30.
Therefore, using y = mx + b form, the equation is y = 1/2x + 30
Then, to find how many miles you drove if the cost was $105, we can plug in 105 for y in the equation.
105 = 1/2x + 30
75 = 1/2x
x = 150
There are 4 bees and 12 ladybugs. So the ratio is
4 : 12
Reduce to lowest term, we get :
1 : 3
Answer:
The number is 6
Step-by-step explanation:
Let x be the number
five times means multiply
5x
is 30 means equals 30
5x= 30
Divide each side by 5
5x/5 = 30/3
x = 6
In one year, $ 9,000 with a profit of 7.75%, is $ 697.5
697.5 × 18 = 12555
After 18 years old, it is $ 15,222
