GCF (Greatest Common Factor)
6: 1,2,3,6
20: 1,2,4,5,10,20
2 is the greatest number in both, therefore there can only be 2 groups of 3 sopranos, and 10 altos.
Its b.) 48 i think don't hold me to it
Answer:
y = -2/3x + 22/3
Step-by-step explanation:
An equation is written in slope-intercept form when it is written as:
y = mx + b, where m is the slope of the line and b is the y-intercept.
Therefore, because we are given m and a coordinate pair of the line, we can use the point-slope formula to make the equation.
The point-slope formula is 
.
Because we are given only one coordinate pair, it is labeled as 
.
Now, just plug in this information and solve the equation.
y - 4 = -2/3(x - 5) Distribute the -2/3 throughout the terms.
y - 4 = -2/3x + 10/3 Add 4 to both sides of the equation.
y = -2/3x + 22/3
I'm sorry, but you seem to be missing parts, and pieces of your question let me know when you update it!!
Answer:
possible solutions (2,11) (3,10)
Step-by-step explanation:
Variable Definitions:
x=the number of hours babysitting
y=the number of hours walking dogs
“no more than 14 hours"→14 or fewer hours
Therefore the total number of hours worked in both jobs, x+y, must be less than or equal to 14
x+y≤14
“no less than $120"→$120 or more
Aubrey makes $8 per hour babysitting, so in x hours she will make 8x dollars. Aubrey makes $10 per hour walking dogs, so in y hours she will make 10y dollars. The total amount earned 8x+10y must be greater than or equal to $120:
8x+10y≥120
Solve each inequality for y:
x+y≤14
y≤14−x
8x+10y≥120
10y≥120−8x
y≥ -4/5x+12
Graph y≤14−x by shading down and graph y≥-4/5x+12 by shading up
