X=number of boys
y=number of girls.
We can suggest the following system of equations:
x+y=33
x/y=3/8
We solve this system of equations by substitution method.
x/y=3/8 ⇒x=3y/8
(3y/8)+y=33
least common multiple=8
3y+8y=33*8
11y=33*8
y=(33*8)/11
y=3*8
y=24
x+y=33
x+24=33
x=33-24
x=9
number of boys /total number of students=9/33=3/11
There are 9 boys and 24 girls in the class.
Answer: C: 9. since 3/11 of the students are boys.
Your answer would be y< -3/2x+1
You slope is negative because the line goes from left to right and your slope is -3/2 because it rises 3 and goes to the left 2. Remember that your slope represents your rise over your run.
Your equation is also only > and not less then or equal to because it is a dotted line.
Happy studying!
Answer:
(y2-y1)/(x2-x1)
Step-by-step explanation:
Average rate of change is just using the slope formula: (y2-y1)/(x2-x1)
Answer:
6.2 gallons of orange juice left.
Step-by-step explanation:
Total orange juice = 8 gallons
Used orange juices to make popsicles = 1.8 gallons
We need to find how much orange juice does Tracy have left.
Left orange juice = Total orange juice - used orange juice
= 8 gallons - 1.8 gallons
= 6.2 gallons
Hence, 6.2 gallons of orange juice left.
