Answer:
The answer would be 9
Step-by-step explanation:
Step 1: Our output value is 30.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$30=100\%$.
Step 4: Similarly, $x=30\%$.
Step 5: This results in a pair of simple equations:
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
Step 7: Again, the reciprocal of both sides gives
Therefore, 30% of 30 is 9
Answer:
Tax amount = $15.00 x 0.06 =0.9
Total amount of the basketball = $15.00 x 1.06 = $15.90
In order to solve these you first need a ratio.
From what we can tell, the ration from LEFT to RIGHT is:
2:3
Therefore, in order to have a 2:3 ratio, we need 5 parts total (2 parts on left + 3 parts on right = 5 total parts!)
A) 60
B) 90
Answer:
The table is:
x y
1 1
2 5
3 9
The graph B shows the relationship y=4x-3
Step-by-step explanation:
We need to fill the table using the rule:
To find y multiply x by 4 and then subtract 3.
Writing rule in mathematical form:
y=4x-3
Now for completing the table we need to put x=1,2 and 3 and find values of y
So, the table is:
x y
1 1
2 5
3 9
The graph B shows the relationship y=4x-3
