Answer:
a) t=b-5 b) j=b+3+2
Step-by-step explanation:
t is tina, we don't know how much Ben scored so we use b, then subtract 5 because tina got 5 less. same thing for Juan but we add the 3 points he got more than Ben and the 2 extra credit points
Answer:
2x-y=4
Step-by-step explanation:
y=mx+b
b is the y-intercept which is -4
y=mx-4
find m(slope)
(2,0) and (0,-4)
(-4-0)/(0-2)
-4/-2=2 m=2
y=2x-4
add 4 to both sides
y+4=2x subtract y
4=2x-y
It says write in standard form which looks like this: 3x + 5y = 4
Assuming that the two investments are X & Y
X + Y = 6300
X = 6300 - Y (1)
9/100X + 4/100 Y = 372 (2)
replacing X from (1) into (2)
9/100(6300-Y) + 4/100 Y = 372
567 - 9/100Y +4/100Y = 372
(-9+4)/100Y = 372 - 567
5/100Y = -195
Y = 100*195/5 = 3900
From (1) we can get X
X = 6300 - 3900 = 2400
I hope this is helpful
6(2x + 5y)
6[2(3) + 5(4)]
6[6 + 20]
6(26)
156
The answer is 156
Hope this helps :)
