Answer:
10 lbs
Step-by-step explanation:
25 is to 5 as x is to 2
25/5 = x/2
2 * 25/5 = x = 10 lbs
P=33+6.71
= 39.71
add 33+ 6.71
I know that b and d are correct because c is just silly and a is just incorrect :)
Answer:
x = 1/2 y = -1/3
Step-by-step explanation:
Split it into 2 equations:
10x-9y=8
and
21y+15x=0.5
10x - 9y = 8
Step 1: Divide both sides by 10:
x = (8+9y)/(10)
Substitute x = (8+9y)/(10) into 21y+15x=0.5 :
21y + (3(8+9))/(2) = 0.5
Solve for y
<u>y= -1/3</u>
Substitute y= -1/3 into x = (8+9y)/(10)
<u>x = 1/2</u>
