Answer:
g > 2t , 15 t + 9g >500 are the inequalities which can be used to find the value of g and t.
Step-by-step explanation:
Earning at grocery store = $9 per hour
Earning as tutor = $15 per hour
Let the number of hours she tutors = t
and the number of hours she works at grocery store = g
Total earning she wants = $500
Now, the earning from tuition = 15 t
Earning from Grocery store= 9g
According to the question:
g > 2t
15 t + 9g >500
Hence, both the above inequalities can be used to find the value of g and t.
Answer:
Step-by-step explanation:
another way to express 52+24 is 4(13+6)
6(t-3)=2(9-2t)=
We move all terms to the left:
6(t-3)-(2(9-2t))=0
We add all the numbers together, and all the variables
6(t-3)-(2(-2t+9))=0
We multiply parentheses
6t-(2(-2t+9))-18=0
We calculate terms in parentheses: -(2(-2t+9)), so:
2(-2t+9)
We multiply parentheses
-4t+18
Back to the equation:
-(-4t+18)
We get rid of parentheses
6t+4t-18-18=0
We add all the numbers together, and all the variables
10t-36=0
We move all terms containing t to the left, all other terms to the right
10t=36
t=36/10
<h2>
t=3+3/5</h2>
Do it step by step
ab+3c
(-6)(-2)+3(5)
A negative times a negative is positive. (-)(-)=+
12+3(5)
12+15
=27
Luke: 2 miles in 40 minutes, 20 minutes a mile, (2/40 = 20 minutes a mile)
Luke's speed is 3 miles an hour (60minutes/20minutes a mile = 3miles).
Sally: 0.05 miles a minute, 60 minutes in an hour, 60 x 0.05 = 3 miles an hour. Or 0.05 miles a minute, 40 minutes walked, 40 x 0.05 = 2 miles walked.
There are a few other ways to show that they are accurate rates.
So yes, they are both correct rates.
