Answer:
a^3+1
Step-by-step explanation:
Solve by substitution
Answer:
(1,4)
Step-by-step explanation:
Answer: x = 1, y = 4
Steps: 3y + 4x = 16, -2x + y = 2
Isolate y for 3y + 4x = 16: y = (16 - 4x ÷ 3)
Substitute y into the other equation (-2x + y = 2): -2x + (16 - 4x ÷ 3) = 2
Simplify: 16 - 10x ÷ 3 = 2
Isolate x for 16 - 10x ÷ 3 = 2: x = 1
Substitute x = 1 into y = (16 - 4x ÷ 3): y = 16 - 4x · 1 ÷ 3
y = 4, x = 1

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
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.
Example:
2 + 3x + 4y = 7 is an expression.
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

2x+40
x+50
4x
Answer:
27
Step-by-step explanation:
The sum of all exterior angles of any quadrilateral= 360°
3x+2x+40+x+50+4x = 360°
11x + 90 = 360°
11x = 360 - 90
10x = 270
x = 270/10
x = 27
