Create three different expressions that are each equal to 20. Each expression should include only these three numbers:
4
-2
10
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The three expressions that use only 4, -2, and 10 and that are equal to 20 are:
4 x 2 - (-2) + 10
4 x 10 + (-2) x 10
-2 x (-2) + 4x4
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

We have,
20
The three expressions that are equal to 20 using only 4, -2, and 10 are:
First expression:
4 x 2 - (-2) + 10
= 8 - (-2) + 10
= 8 + 2 + 10
= 20
Second expression:
4 x 10 + (-2) x 10
= 40 - 20
= 20
Third expression:
-2 x (-2) + 4x4
= 4 + 16
= 20
Thus,
The three expressions that use only 4, -2, and 10 and that are equal to 20 are:
4 x 2 - (-2) + 10
4 x 10 + (-2) x 10
-2 x (-2) + 4x4

Find the value of x
Answer:
134 degrees
Step-by-step explanation:
the angles in a triangle always add up to 180.
86+48=134
to find the last angle you subtract 180-134
this gives you 46 degrees
a straight line is always measured as 180 degrees.
180-46=134
so x=134 degrees

-5n+4n-7=8
What is the answer for n and how do you solve it
Answer:
-15
Step-by-step explanation:
First combine like terms, aka the variables
-5n+4n-7=8
-1n-7=8
Then, isolate the variable by adding 7 to both sides
-1n-7+7=8+7
-1n=15
Finally, solve by dividing both sides by -1
-1n/-1=15/-1
n=-15
Answer:
n = -15
Step-by-step explanation:
I'll try my best to explain how I solved this
Equation:
-5n + 4n -7=8
Add the light terms on each side:
-n -7 =8
Separate the variables from the numbers:
-n = 15
Do the operation necessary to solve it:
n = -15

Step 3:
8 = 8 + 3x Combine Like Terms
Step 4:
0 = 3x Subtract 8 on both sides
Answer:
x = 0
