Answer:
x < 79
Step-by-step explanation:
The amount they scored (x or any other variable) is less than 79, so you have to use a less than sign.
Answer:
The bottom one.
Step-by-step explanation:
The equation would look like
Y=-4x+7
Y=mx+b
5.7y-5.2=y/2.5
Add 5.2 to both sides:
5.7y = y/2.5 + 5.2
y/2.5 = 0.4y
5.7y = 0.4y + 5.2
Subtract 0.4y from both sides:
5.3y = 5.2
Divide both sides by 5.3:
y = 5.2/5.3
y = 0.98113
