Answer:
x = 7
Step-by-step explanation:
Order of operations rules require that we do multiplication and division BEFORE addition and subtraction.
Let's start by simplifying the expression. Adding 15 to both sides results in:
8,000÷(28x+4) = 40.
Multiplying both sides by (28x + 4) results in the simpler:
8000 = 40(28x + 4).
Dividing both sides by 40 results in:
200 = 28x + 4, or
196 = 28x
Solve for x by dividing both sides by 28:
x = 7
Answer:
b= -8/5
Step-by-step explanation:
-5-3=7b-3b
-8=5b
b= -8/5
It can be achieved by substituting the formula for length i.e x(A) = A/6 into the formula for Volume.
in the diagram( please mind my writing)
the x(A) is substituted into V(x) .
Only thing left is substitution of the values .
hope this helps .
Answer:
m=3*sqrt(2) and n=3
Step-by-step explanation:
tan(45)=3/n
1=3/n, n=3. As it's a right angled triangle, 3^2+3^2=m^2, m=3*sqrt(2)
Answer:
He will have 10.
Step-by-step explanation:
this is an example of <em>the counting principle.</em>
