Answer:
3-11n>21-5n
Step-by-step explanation:
It seems right, so hopefully it is.
A. <span>2x + 5y= 10
5y= -2x+10
</span>-> y= -2/5x+2
b. The slope is 2
c. For the y intecpet, x is always 0
y= -2/5x+2
y= -2/5(0)+2
y=0+2
y=2
(0,2) is the y-interecpt
d. Please veiw below

Step-by-step explanation:
Answer:
1. The first problem is wrong, it should be 0.5(3(15) + 2(20)) because the parentheses make sure that every purchased item is being divided by 2 (multiplying by 0.5 is the same as dividing by 2)
2. The second problem is partially correct. The first two answers you have checked are correct, but the last one is wrong. The third answer should be 6 + 12 instead because that's just a simplified version of 2(3) + 6(2), meaning they are equal
3. I cannot read your answers in the "Why or Why Not" column in the third problem, but the answers you gave in the "Evaluate" and "Does It Work?" columns are all correct.
Answer:
The distance from Gary's school to the BART station is 564 yards
Step-by-step explanation:
Let
x ----> the distance from Gary's school to the corner market
y ----> the distance from Gary's school to the BART station
we have

we know that
To find out the distance from Gary's school to the BART station, multiply the distance from Gary's school to the corner market by 12
so

substitute the value of x

therefore
The distance from Gary's school to the BART station is 564 yards
