What is the sum of 2x+1 and its opposite?
Answer:
Zero. The sum of anything and it's opposite is zero, that's how an opposite is defined . In this case, the opposite of 2x+1 is -(2x+1)=-2x-1 by the distributive property . Adding like terms, 2x+-2x+1+-1=0+0=0.

Answer:
x = 52
m<ACD = 159
m<ACB = 21
Step-by-step explanation:
1) Set up an equation.
2x + 55 = 3x + 3 (the two interior angles on the opposite of the triangle and the exterior angle are equal to the exterior angle)
2) Solve for x.
2x + 55 = 3x + 3
-x + 55 = 3
-x = -52
x = 52
3) Substitute 'x' into each angle required to find m<ACD and m<ACB.
m<ACD = 3(52) + 3
= 156 + 3
= 159
CHECK:
2(52) + 55 = 159
104 + 55 = 159
159 = 159
m<ACB + m<ACD = 180
m<ACB + 159 = 180
m<ACB = 21

A bookcase is 4 ft tall. A model of the bookcase is 6 ft tall. What is the ratio of the height of the model bookcase to the height of the real bookcase?
Answer:
4:6
Step-by-step explanation:
The ratio of the height of the model bookcase to the height of the real bookcase will be 3: 2.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
A bookcase is 4 ft tall. A model of the bookcase is 6 ft tall.
The ratio of the height of the model bookcase to the height of the real bookcase is given by the division of the numbers 4 and 6. Then we have
Ratio = 6 / 4
Simplify the ratio, then we have
Ratio = 6 / 4
Ratio = 3 / 2
Ratio = 3: 2
The ratio of the height of the model bookcase to the height of the real bookcase will be 3: 2.

His mother says, “The sum of 10 and two-thirds of that tree’s age, in years, is equal to 50.”
Javier writes the equation (10 + two-thirds) a = 50, where a is the tree’s age in years. His equation is not correct. What error did he make?
Answer:
Javier's equation is not correct because the variable "a" should be multiplied by only and then added to
Step-by-step explanation:
Let
a------>is the tree’s age in years
we have that
-------> Javier's equation
we know that
The equation that represent the situation is equal to
Solve for a
Multiply by both sides
Javier's equation is not correct because the variable "a" should be multiplied by only and then added to
3x-2y=1x+4y=33 elimination process
Answer:
x = 5 ; y = 7
Step-by-step explanation:
3x - 2y = 1 --------------------(I)
x + 4y = 33 ------------(II)
Multiply equation (II) by (-3) and then add. So, x will be eliminated and we can find the value of y
(I) 3x - 2y = 1
(II)*(-3) -3x -12y = -99 {Now add}
- 14y = -98
y = -98/14
y = 7
Plugin y = 7 in equation (I)
3x - 2*7 = 1
3x - 14 = 1
3x = 1 + 14
3x = 15
x = 15/3
x = 5
-3p>-48 Solve the inequality
9514 1404 393
Answer:
p < 16
Step-by-step explanation:
Dividing the inequality by a negative number will reverse the comparison.
-3p > -48
(-3p)/(-3) < (-48)/(-3) . . . . divide both sides by the coefficient of p
p < 16
_____
Alternate solution
Add 3p+48 to both sides.
-3p +(3p +48) > -48 +(3p +48)
48 > 3p
Divide both sides by 3; no reversal is necessary.
16 > p . . . . . same answer as above, without the comparison reversal

6051 was rounded to the nearest one. What is the lower bond ?
Answer:
6050.5
Step-by-step explanation:
The key to this is "rounded to the nearest one"
If the question was to say "round to the nearest 10" you would do 10÷2 = 5
Always divide by 2
1 ÷2 = 0.5
6051 - 0.5 = 6050.5
If it was upper bond it would be:
6051 + 0 5 = 6051.5

The fractions between these heights are -
-1/10 , -2/10, -3/10, - 4/10, - 5/10, - 6/10, -7 /10, - 8/10, - 9/10
What is a mathematical function, equation and expression?Function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function
Expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators
Equation : A mathematical equation is used to equate two expressions.
Given is that while in the water, Meg saw some treasures located between the surface of the water and 1 foot below.
Assume the surface to be at 0 ft. Then, 1 feet below, can be written as -
x = - 1
So, the fractions between these heights are -
-1/10 , -2/10, -3/10, - 4/10, - 5/10, - 6/10, -7 /10, - 8/10, - 9/10
Therefore, the fractions between these heights are -
-1/10 , -2/10, -3/10, - 4/10, - 5/10, - 6/10, -7 /10, - 8/10, - 9/10
