if 5t=5 then t is what number
Answer:
1
Step-by-step explanation:
5t = 5
divide equation by 5 to get rid of it
t = 1
This is because 5t means "5 times t". The t is a placeholder for a number.
To solve for t, we divide both sides by 5
5t = 5
5t/5 = 5/5
t = 1
Note how 5t = 5 becomes 5*1 = 5 after replacing t with 1. Because 5*1 = 5 is a true statement, this helps confirm we have the correct answer.

Round 69581.491337 to the nearest thousand.
Answer:
7000
Step-by-step explanation:
lets start with 695
9 is the thousand
you check the number next to 9
less then 4 let it rest
more than 5 let it soar
something like that lol
anyways since 5 is next to the 9 we round up from 9 to the next number which is 10
so that changes the whole number to 7000
hope this makes sense!

The total amount of milk in a jug and a mug is T liters. If p ml of milk is taken from the mug to make pancakes, the amount of milk left in the mug will be half as much as that in the jug. Write an expression for the amount of milk, in liters, in the jug. Evaluate the expression if T = 2.5 and p = 250.
Answer:
Apart from PB&J and oatmeal, pancakes are the most popular (and best) breakfast meal. They’re nutritious, yummy and can be served with both salty and sweet flavors. But are they easy to make? The recipe may be simple, but there are many things we need to consider.

The indoor climbing gym is a popular field trip destination. This year the senior class at High School A and the senior class at High School B both planned trips there. The senior class at High School A rented and filled 3 vans and 12 buses with 504 students. High School B rented and filled 2 vans and 4 buses with 184 students. Every van had the same number of students in it as did the buses. Find the number of students in each van and in each bus.
High school A: 3 vans + 12 buses = 504 students
High school B: 2 vans + 4 buses = 184 students
Multiply High school B by 1.5:
High school B: 3 vans + 6 buses = 276 students
Subtract High school B from High School A:
6 buses = 228 students
Divide students by buses:
Buses = 228 / 6 = 38 students per bus
Now solve for vans using high school A:
3 vans + 12(38 students per bus) = 504 students
Simplify:
3 vans + 456 students in buses = 504 students
Subtract students in buses from both sides:
3 vans = 48
Divide both sides by 3:
Vans = 16
Answer: vans = 16 students, buses = 38 students

What is the slope of the line that passes through the points (5, 4) and (13.25, -18) ?
A.) 83/3
B) 3/8
C) −3/8
D) 8/3
Answer:
Answer: D. 8/3
Step-by-step explanation:
Formular for slope:
[ consider points (x1, y1) and (x2, y2) ]
[tex]slope = \frac{y_{2} - y _{1} }{x _{2} - x _{1} } \\ [/tex]
x1 » 5, y1 » 4
x2 » 13.25, y2 » -18
[tex]sloe = \frac{ - 18 - 4}{13.25 - 5} \\ \\ = \frac{22}{8.25} \\ \\ { \boxed{ \boxed{slope \: = \frac{8}{3} }}}[/tex]
Which inequality represents all values of x for which the quotient below is
defined?
28(x-1) = 8x?
O A. x less than or equal to -1
B.x great than or equal to 1
O C. x> 1
O D. x<-1
You can re-write this quotient this way :
[tex]\frac{\sqrt{28(x-1)}}{\sqrt{8x^{2} }} = \sqrt{ \frac{28(x-1)}{8x^{2} } }\\[/tex]
What's inside the square root must be greater than or equal to 0, because the domain of the square root function is defined on R+ (which is [0,+∞))
In other word we must find x so that :
[tex]\frac{28(x-1)}{8x^{2}}\geq 0[/tex]
at the end we get
28(x-1) ≥ 0
28x - 28 ≥ 0
28x ≥ 28
x ≥ 1
So the answer is B, x ≥ 1
