Answer:
80% of 100
Step-by-step explanation:
25% of something is basically dividing it by 4, meaning 25% of 200 is 50,
While 80% of 100 is 80
A good way to memorize this is if youre taking anything as a percent of 100, get rid of a 0 on the 100, and put a decimal place in the number.
(e.g. 90% of 10 is 9. whereas 90% of 100 is 90)
Just remember which you're dealing with!
Hope this helps!
Answer:
The amount left after each friend got $46.
Step-by-step explanation:
Any time you see R1 in bus stop method division, it just means remainder. So dividing 93 dollars between 2 friends gives them both 46 dollars, with one left over!
Hope this helps :)
The answer would be 80 because you are multiplying each number by 2. You multiply 5 x 2 = 10, 10 x 2 = 20, 20 x 2 = 40, and then 40 x 2 = 80. That is how I got the answer 80!!
Answer: a=24
Step-by-step explanation:
Lets find the line's formula (equation of the line).
As known the general formula of any straight line (linear function) is
y=kx+b
Lets find the coefficient k= (Yb-Ya)/(Xb-Xa)=(9-7)/(-4-3)=-2/7
(Xb;Yb)- are the coordinates of point B
(Xa;Ya) are the coordinates of point A
Now lets find the coefficient b. For this purpose we gonna use the coordinates of any point A or B.
We will use A
7=-2/7*3+b
7=-6/7+b
b=7 6/7
So the line' s equation is y= -2/7*x+7 6/7
Now we gonna find the value of a usingcoordinates of point C.
Yc=1, Xc=a
1=-2/7*a+7 6/7
2/7*a= 7 6/7-1
2/7*a=6 6/7
(2/7)*a=48/7
a=48/7: (2/7)
a=24
5 - 8x < 2x + 3
5 - 8x < 2x + 3
<u>-3 - 3 </u> Step 1.
2 - 8x < 2x
<u> +8x +8x </u> Step 2. Missing step
2 < 10x
<u>÷10 ÷10</u> Step 3.
<u>2/10 < x</u>
<u>1/5 < x
The missing step is add 8x to both sides of the inequality.</u>
