Answer:
6, 9
Step-by-step explanation:
Let x represent one of the numbers. Then the other number is 15-x (because their sum is 15). The relation between the numbers is ...
2x -3 = 15 -x . . . . . three less than twice one number is the other number
3x = 18 . . . . . . add 3+x
x = 6 . . . . . . divide by 3
15-x = 9 . . . . find the other number
The two numbers are 6 and 9.
Answer:
given below
Step-by-step explanation:
let the number of gloves be y
then number of masks is y + 8
therefore a equation can be formed:
18(y) + 24(y + 8) = $612
18y+24y+192=612
42y=420
y=$10
each glove cost $10
therefore each masks cost $18
the answer is a || b, or the first option
Answer:
The second equation can be used
Step-by-step explanation:
Just plug in the values and the equation should look like this 8^2 + b^2 = 12^2
12 is the hypotenuse to plug that into c
and 8 is just a leg so you can either put it in a or b
Answer:the answer is c
