Answer:
n = -45
Step-by-step explanation:
<u>Turn 2/3n into 2n/3:</u>
2n/3 + 4 = -26
<u>Subtract 4 from both sides:</u>
2n/3 + (4 - 4) = -26 - 4
<u>2n/3 = -30</u>
<u>Multiply 3 from both sides:</u>
2n = -30 * 3
2n = -90
<u>Divide 2 from both sides:</u>
<u>2n = -90</u>
2 = 2
n = -45
99,019,900 would be ninety-nine million nineteen thousand and nine hundred hundred
Answer:
x=3, y=0.8
Step-by-step explanation:
8x+5y=28
4x+5y=16
Subtract the second simultaneous equation from the first.
You are left with: 4x=12
12/4=3
x=3
Substitute this back into one of the equations.
8(3)+5y=28
8*3=24
28-24=4
4=5y
4/5=0.8
y=0.8
I believe it’s b or A but it’s most likely b
