The sale price is 4/5 of the original price...with x being the original price
4/5x
0.8x
these are the same because 4/5 = 0.8..its just in decimal form
Answer:
4
Step-by-step explanation:
So your equation is 1.6(x-y)/2
Since x=10, and y=5, we need to substitute the amounts in to the equation.
so...
1.6(10 -5)/2
Using PEMDAS, parenthesis comes first. So solve what 's in the parenthesis (10 - 5).
So..
1.6(5)/2
Next, multiply 1.6 by 5.
1.6 x 5 = 8.
So you are left with the equation
8/2
and 8 divided by 2 is...
4!
Answer:
DISCLAIMER:I'M NOT REALLY GOOD AT MATH
Surface area=¶r squared.
¶=3.14
Radius=D/2
=10/2
5
therefore,3.14×5×5
=78.5
<span>Let x=time required to mow the lawn if both work together
Then both work at the rate of 1/x lawn per min
fred works at the rate of 1/60 x
</span>Bullwinkle <span>at the rate of 1/90 x
</span>1/60 + <span>1/90 = 3/180 + 2/180 = 5/180 = 1/36
</span>
<span>rate of 1/x lawn per min so 1/36 =1/x
</span>
x= 36 min
fred mow <span>1/60 x = 1/60x36 =36/60= 9/15 of the lawn
</span><span>Bullwinkle mow 1/90 x 36 = 36/90 = 6/15 of the lawn </span>
