Answer:
Step-by-step explanation:
x y Result <= -12?
-8 -3 4 NO
-12 0 -12 YES
-7 9 -43 YES
3 5 -17 YES
1 -8 33 NO
-4 2 -12 YES
X = larger number, y = smaller number
x + y = 38...because the sum of the numbers is 38
x = 2y - 10....larger one is 10 less then twice the smaller
now we will sub in 2y - 10 for x back into the first equation
x + y = 38
2y - 10 + y = 38
3y - 10 = 38...add 10 to both sides
3y = 38 + 10
3y = 48 ...divide both sides by 3
y = 48/3
y = 16
now sub 16 in for y back into either of the original equations and find x
x = 2y - 10
x = 2(16) - 10
x = 32 - 10
x = 22
so ur numbers are 16 and 22
$12.50.
($62.50*0.2) = 12.5
Therefore, you would get a discount of $12.50. Total price would be $62.50 - $12.50.
Answer:
31.5
Step-by-step explanation:
Area of a rectangle = lw
Substitute: 7*3 = 21
Area of a Triangle = 1/2*bh
Substitute: 1/2*(3)(7) = 10.5
Area = 21 + 10.5 = 31.5
