Answer:
10x-15y
Step-by-step explanation:
So, when they say use the distrubutive property, they basically mean turning this:
a(b+c)
Into this:
ab+ac
So in this case, it would be:
5(2x-3y)
And we will turn it into:
10x-15y
ANother way to think about it is we are multiplying 2x by 5, and -3y by 5. So:
2x*5
=
10x
And
-3y*5
=
-15y
Then we can combine these two:
10x-15y
Hope this helps!
Answer:
240000000
Step-by-step explanation:
3*80000000
=240000000
Answer:
So all you need to do is find 5% of 13000 which is 650.
Now 650 times 11= 7150
13000+ 7150=
20,150
Answer:
720
Step-by-step explanation:
because 8% of 9000$ is 720$.
another way.
Step 1: Our output value is 9000.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$9000=100$.
Step 4: Similarly, $x=.8%$.
Step 5: This results in a pair of simple equations:
$9000=100%(1)$.
$x=.8%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
Step 7: Again, the reciprocal of both sides gives
Therefore, 8%of $9000$ is $720
Answer:
54 cm
Step-by-step explanation:
Measures are proportional on a scale drawing:
drawing measure : actual measure = 6 cm : 3 m = x : 27 m
The value on the right of the x ratio, 27, is 9 times 3, so the value of x will be 9 times 6 cm.
54 cm on the blueprint represents an actual distance of 27 meters.
