Answer:

Step-by-step explanation:

8-11 =-3\n\nb. -8+10 = 2\n\nc. 13+(-6) = 13-6 \n= 7\n\nd. 7-(-3)\n= 7+3\n=10\n\ne.-5-(-2)\n=-5+2\n=-3\n\nf. -15-(-25)\n=-15+25\n=10\n\ng. -3+(-6)-(-9)\n= -3-6+9\n=-9+0\n=0\n\nh.-20-(-9)-(-8)\n=-20+9+8\n-20+17\n=-3\n\n

-2+3-(-4)+(-5)\n-2+3+4-5\n= 1-1\n=0\n\n\nb. 18-(-10)+(-19)-8\n=18+10-19-8\n28-27\n=1\n\nc. 65+(-72)-(-45)\n= 65-72+45\n=-7+45\n=38

What is Equation?

Equations are mathematical statements with twoalgebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

The temperature T in degrees Celsius of a liquid t minutes after heating is given by the formula T=8√t.

So, when the temperature = 48 degree Celsius

48 = 8√t

48/ 8 = √t

6 = √t

t= 2.445

t= 2.5  min

Hence, the time will taken 2.5 min.

T=8√t
T=temperature
t=time in minutes.
If T=48, we have to calculate the time.

48=8√t
(48)²=(8√t)²
2304=64t
t=2304 / 64=36

answer: 48 degrees Celsius will be reached in 36 minutes.

Abed says he has written a system of two linear equations that has an infinite number of solutions. One of the equations of the system is y = 3x – 1. Which could be the other equation?

Answers

y = 3x + 23x – y = 23x – y = 1 3x + y = 1

The correct answer is:

Any equation that is a multiple of y=3x-1.

Explanation:

In order to graph as the same line, the equations must be the same.  This means that all pieces of the first equation must be multiplied by the same factor, or the equation must be rewritten.

Suppose the radius of a circle is 8. what is its circumference

Answers

16 because the circumference is 2x the amount of the radius :) please give 5 stars and a thankyou button :)
First, here is the formula for finding circumference using the RADIUS:
C (circumference) = 2 x pi (3.14) x r (radius)
using the DIAMETER:
C = pi (3.14) x d (diameter)
------------
Using the above formula, just plug in the numbers!!
C = 2 x (3.14) x (8)
C = 50.24
50.24 is your answer

if you wanted to use diameter, you should know that diameter is just the radius times 2!
