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
Answer:
QS=51
Step-by-step explanation:
It was given that RS = 19 and QR =32
QS=x
Q-R was measured and found to be 32
R-S was measured and found to be 19
Q-S will be the sum of Q-R and R-S which is 32+19= 51
QS=51
Answer:
A, D
Step-by-step explanation:
They are true statements.
Step-by-step explanation:
Scores of Australia in all four matches starting from 1st 208, 192, 241, 203 respectively.
Similarly, scores of Pakistan in all four matches starting from 1st 102, 202, 360, 276 respectively.
The avg of Pakistan in one match = (102+202+360+276)/4 = 235
The avg of Australia in one match = (208+192+241+203)/4= 211
Since, the avg score of Pakistan is more than that of Australia, Pakistan performed better.
