if your asking for the equation, it's t + 7 < 3
Answer:
12
Step-by-step explanation:
3x^2
because the information provided states that x = -2, that is what we are going to replace x with.
3(-2)^2
the next step is to evaluate the power because that is next in PEMDAS.
(-2)^2 = 4
that leaves us with:
3 * 4 = 12 ( the " * " represents the multiplication sign)
hope this helps!
Answer:
Step-by-step explanation:
We need to find the solution to the following system of equations:
and 
By plugging the value of 'y' into the first equation we have that:
⇒ 
Solving for 'x' we have:
So, the solution to the system of equation is: (37.5, -30)
Answer:
∠ 8 = 140°
Step-by-step explanation:
∠ 8 and 40° are adjacent angles and supplementary ( sum to 180° ), then
∠ 8 = 180° - 40° = 140°
Answer:
Yasmin will spend $6
Nadia will spend $5.9
Step-by-step explanation:
Step one:
the cost of 5 jars at Central market is $3
the cost of 1 jar = 3/5= $0.6
60 cents per jar
we are told that Valley Market sells jars of jam at 59 cents per jar.
$0.59
Step two:
If Yasmin buys 10 jars from Central Market,
Yasmin will spend = 10*0.6= $6
If Nadia buys 10 jars from Valley Market.
Nadia will spend = 10*0.59= $5.9
The market difference is 6-5.9= $0.1
