Answer:
I am pretty sure the answer is 4
Step-by-step explanation:
because 4 × 5 = 20 and 18 + 20 = 38
so if he rides 4 miles for 5 more days he will reach 38
(hope that helped)
Ie 32^2 - 4ac=0 so ac=256 and a+c=130
So, that means:2 equations ac=256 a+c=130 ie c=130-a
So,a(130-a)=256 so 130a -a^2=256 ie a^2-130a +256=0 (a-2)(a-128)=0
Finally,giving a= 2 or a=128 so, a=2 c=128 or a=128 c=2
Since, a>c , a=128 and c=2 ie (128,2)
The area is 76 ft squared, and the perimeter is 43.1 ft. CORRECT ME IF IM WRONG BECAUSE I WAS SO BAD AT AREA/PERIMETER
You'll have to solve simultaneously
let nickel be x, dime be y
x + y = 35 ... ( 1 )
5x + 10 y = 250
5 ( x + 2y ) = 250
x + 2y = 50 ... ( 2 )
in ( 1 )
x = 35 - y ( 3 )
sub ( 3 ) into ( 2 )
( 35 - y ) + 2y = 50
y = 15
sub y into ( 1 )
x + y = 35
x + 15 = 35
x = 20
therefore, Sandy has 20 nickels and 15 dimes
Hello! And thank you for this question!
For this equation all you will do is use the distribution property.
6*y + 6 * 8
6y + 48
Final Answer:
6y + 48
