Answer:
18/90=9/x and to find x use proportion so first 90*9=18x and 810=18x and x-45
Step-by-step explanation:
The two equations are in the slope-intercept form, y = mx + b.
m is the slope and it is the rate of change.
b is the constant, and it is the initial value.
Eq. A: y = 3x + 4 ---> rate of change = m = 3; initial value = b = 4
Eq. B: y = 5x + 2 ---> rate of change = m = 5; initial value = b = 2
Now you can see which statement is true.
A. False
B. True
C. False
D. False
Answer:
The answer is 30.
Step-by-step explanation:
Don't worry about the x and y it just make your head confuse, that's what my teacher said just add up the number.
First you would do parenthesis according to the PEMDAS(Parenthesis, Exponents, Multiply, Divide, Add, Subtract) Rule
4 -2(-5a -10) = 30
4 + 10a + 20 = 30
Now you need to add 4 and 20 because they are on the same side
24 + 10a = 30
Now subtract 24 on both sides
24 + 10a = 30
-24. -24
10a = 6
Last divide 10 from both sides
10a/10. = 6/10
a= 6/10
Last simplify (optional but recommended)
a = 3/5 or 0.6
Hope this helped :)
A = 0.6
Answer:
The volume is 1436.8
.
Step-by-step explanation:
-To find the volume of a sphere, you need the formula:
-Use the radius for the formula:
-Then, you solve:
× 
× 
× 
-Round the answer to the nearest tenth:
So, therefore the volume is 1436.8 .
