hello!! So I’m in 5th grade (middle school in my state :]) and I have a question.
what is 5 x 23 x 2 ? Please help! I didn’t understand anything in the mah lesson today and I’m behind.
if you can help that’d be a help!
also please tell me how the answer was gotten!
5 x 23 x 2
Answers
Answer:230
Step-by-step explanation:
5 x 23= 115
115 x 2= 230
5 x 23 x 2
To make it easier let’s pick two numbers to begin with and the sum of those two numbers will be multiplied by 23
5 x 2 is the easiest to multiply so 5 x 2 = 10
And then 10 x 23 = 230
This is it I hope you understood and this helped you

Solve the following equations:

The solution of given equation is 5.04.
To find the solution of given equation.
What is algebra?A part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.
Given that:
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
4 1/5 ÷ 1 1/5 = 11 - 1 7/18x
convert into simple fraction form, we get
21/5 ÷ 11/5=11-17x/18
convert divide into multiply
21/5*5/11=11-17x/18
cancel out 5 from numerator and denominator, we get
21/11=11-17x/18
same form are in same side
17x/18=11-21/11
after simply, we get
17x/18=121-21/11
17x/18=100/21
cross multiplication on both sides and find x,we get
x=100*18/21*17
x=5.04
So, the solution of given equation is 5.04.

Answers
Answer:
(10,0)(-1,0)
Step-by-step explanation:
x^2 - 9x - 10 = 0
(x - 10)(x + 1) = 0
The two solutions are
x - 10 = 0
x = 10
or
x+1 = 0
x = - 1
Answer:
x=10, x=-1
Step-by-step explanation:
Hi there!
We are given this equation:
x²-10=9x
And we want to solve it by factoring
Factoring is easier to do when all of the terms are on the same side, so let's subtract 9x from both sides
x²-9x-10=0
Now we must think of two numbers that add up to -9, but multiply to get -10
Those numbers are -10 and 1
So factor the polynomial using FOIL:
(x-10)(x+1)=0
Now split and solve via the zero product property:
x-10=0
Add 10 to both sides
x=10
x+1=0
Subtract 1 from both sides
x=-1
