Answer:
Step-by-step explanation:
2.A
160 $ = 100%
x $ = 70%
100 x = 11200
x = 112
160,00 - 112,00 = 48,00$
Answer:
Step-by-step explanation:
Multiply 100*$15 to find the loss. (1500)
Multiply 100*$21.75 to find what was made. (2175)
Subtract 2175-1500
Total=$675
Answer:
y=5/3x-3
Step-by-step explanation:
first, let's put 3x+5y=15 into y=mx+b form
move 3x to the other side
5y=-3x+15
divide by 5
y=-3/5x+3
now, perendicular lines have slopes that are negative and reciprocal.
With our new equation we can automatically find the slope, which would be 5/3.
now, we need to find b
plug the points (3,2) into y=5/3x+b
2=5/3(3)+b
2=5+b
-3=b
so that means that our equation will now be
y=5/3x-3.
Hope this helps!
Answer:
70° and 20°
let the other 2 angles be 7x and 2x
90+7x+2x=180
9x=180-90
x=90/9
x=10
7x=7x10
70
2x=2×10
