Step-by-step explanation:
x be the number of oranges
x + (x+2) = $4.20
2x + 2 = 4.20
2x = 2.20
x = 1.1
if you wanna check,
1.1 + (1.1 + 2) =$4.20
1.1 + 3.1 =$4.20
4.2 =$4.20
Alex = x = 1.1 oranges
Bobbie = (x+2) = 1.1 + 2 = 3.1 oranges
I'm not sure of the answer tho^^

The sum of any number and its ______
equals 0.
Answer:
The sum of the real number (a) and its opposite real number (-a) is zero
Step-by-step explanation:
5 + (-5) = 0 and (-5) + 5 = 0
or, 5 - 5 = 0 and -5 + 5 = 0
Here 5 is real number and (-5) is it's opposite real number. Sum of 5 and (-5) is zero.

is 4(x-8)=4x-8 One solution no solution or infinite solutions explain your answer
Answer:
No solution
Step-by-step explanation:
4(x-8) = 4x-8
Distribute.
4x-32 = 4x-8
Subtract 4x first and get rid of the variable (x).
4x-32 = 4x-8
-4x -4x
-32 = -8
-32 does not equal -8, so there is no solution!

The solution to 5(x-2)-6=24 is which of the following? Show the steps in your solution process.
Answer:
x=8
Step-by-step explanation:
distributive property
5x-10-6=24
adding -10 and -6 which is -16
5x-16=24
add 16 on both sides to cancel the -16
5x=40
than divide 5 to cancel out the 5
x=8

How to solve trigonometric functions such as
sin 2x sin x + cos x= 0
Use the double angle identity:
sin(2x) = 2 sin(x) cos(x)
Now rewrite
sin(2x) sin(x) + cos(x) = 0
as
2 sin²(x) cos(x) + cos(x) = 0
Factor out cos(x) :
cos(x) (2 sin²(x) + 1) = 0
Consider the two cases,
cos(x) = 0 OR 2 sin²(x) + 1 = 0
Solve for cos(x) and sin²(x) :
cos(x) = 0 OR sin²(x) = -1/2
Squaring a real number always gives a non-negative number, so the second case doesn't offer any real solutions. We're left with
cos(x) = 0
Cosine is zero for odd multiples of π/2, so we have
x = (2n + 1) π/2
where n is any integer.
If x = 4 and y = 7, evaluate the following expression:
20 – (3y – 4x)
Answer:
15
Step-by-step explanation:
x=4, y=7
20-(3y-4x) Substitute the values for the variables:
20-(3*7-4*4) Multiply:
20-(21-16) Parentheses first:
20-5
=15
Hope this helps :)
The solution for the expression 20 – (3y – 4x) will be 15.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the values are x = 4 and y = 7, the expression will be solved as below,
E = 20-(3y-4x)
Substitute the values for the variables:
E = 20-(3 x 7-4 x 4) Multiply:
E = 20-(21-16) Parentheses first:-
E = 20-5
E = 15

You'll have three copies of the red "-x" rectangles to represent -3x
Next, you'll need five copies of the blue squares with the label "1". This represents 5 since 1*5 = 5.
Lastly, you'll need one copy of the purple rectangle that has "y" on it.
All of this forms the expression -3x+5+y
All of these figures will be above the dashed line to be in the positive region.
