add the two discounts of 25 and 10 percent. then your item will be 65% of the price now.
use the pythagorean theorem: a^2 + b^2 = c^2
6^2 = 36
4^2 = 16
36-16 = 20.
the square root of 20 is either a.) the square root of 20 or b.) 4.4721... (rounded 4.5)
D:11a+8b and the other factor would be 11a-8b
since you have 11 cards and need to know how many red and black
r+b needs to equal 11
since r+b=11 isn't shown in any answer then none of them are correct, so none of the above
Step-by-step explanation:
what we trying to find the value of x and y
20x+6=y
x intercept,y=0
20x+6=0-6
20x/20=-6/20
×=-0.3
y intercept,x=0
20(0)+6=y
0+6=y
6=y
(-0.3,0)
19x+7=y
y intercept,x =0
19(0)+7=y
0+7=y
7=y
x intercept,y=0
19x+7=0-7
19x=-7
19x/19=-7/19
x=-0.37
