Answer:
His error is adding 10 and 2/3 before multiplying by a(age of the tree)
Step-by-step explanation:
The sum of 10 and two-thirds of that tree's age, in years, is equal to 50.
Correct equation
Sum = addition (+)
two-thirds = 2/3
The tree's age = a
10 + 2/3a = 50
2/3a = 50 - 10
2/3a = 40
a = 40 ÷ 2/3
= 40 × 3/2
= 60
a = 60 years
Javier writes the equation
(10 + two-thirds) a = 50
(10 + 2/3)a = 50
(30+2/3)a = 50
32/3a = 50
a = 50 ÷ 32/3
= 50 × 3/32
= 150/32
a = 150/32
His error is adding 10 and 2/3 before multiplying by a(age of the tree)
Answer:
His error is adding 10 and 2/3 before multiplying by A...

Question 8 of 19
What is an equation that can be used to solve the proportion?
8/15 = x/6
A. 90x = 8
B. 15x = 48
C. 48x = 15
O D. 8x = 90
8/15 = x/6
Using cross multiplication let us find the value of x .
= 15 × x = 6 × 8
= 15x = 48= x = 48 ÷ 15 ( transposing ×15 from LHS to RHS changes ×15 to ÷+5 )
= x = 3.2
Therefore , the equation that can be used to solve the proportion :-

A certain hybrid car can travel 1 4/11 times as far as a similar nonhybrid car can, each one gallon of gasoline. If the nonhybrid car can travel 33 miles per gallon of gasoline, how far can the hybrid travel on 4/5 gallon of gasoline?
Answer:
On 4/5 gallon of gasoline, hybrid car will travel 36 miles of distance.
Step-by-step explanation:
Suppose, non hybrid car travel "x" distance in 1 gallon of gasoline
then, hybrid will travel " 1 4/11* x" distance in 1 gallon of gasoline
Given that, non hybrid car travel, x = 33 miles per gallon
Then, hybrid car travel, 1 4/11*x = 1 4/11* 33 = 45 miles per gallon
On 1 gallon of gasoline hybrid car travel= 45 miles
On 4/5 gallon of gasoline hybrid car will travel= 4/5*45= 36 miles
On 4/5 gallon of gasoline, hybrid car will travel 36 miles of distance.

all real numbers less than or equal to 9 and greater than or equal to 7 please hurry
Answer:
[tex]7 \leq x \leq 9[/tex]
Step-by-step explanation:
Let [tex]x[/tex] represent the real numbers.
For the first part, all real numbers less than or equal to 9 in algebra is [tex]x \leq 9[/tex].
For the second part, all real numbers greater than or equal to 7 in algebra is [tex]x \geq 7[/tex].
To combine both inequalities, it would become [tex]7 \leq x \leq 9[/tex].
Hope this helped! If not, please let me know! <3
The real numbers are 7, 8, and 9.
We are given two statements:
All real numbers are less than or equal to 9.All real numbers are greater than or equal to 7.We have to use these two statements, form an inequality for the real number and find the real numbers.
What is inequality?Inequality is a relation that makes a non-equal comparison between two mathematical expressions.
There are five types of inequality:
[tex]Less~~than~ = ~ < \\Greater~~than~=~ > \\Less~~than~~or~~equal~~to~=~\le\\Greater~~than~~or~~equal~~to~=~\ge[/tex]
Let the real number be x.
Now using the two given statements we have,
[tex]x\le9\\x\ge7[/tex]
If we combine these two equations we get,
[tex]7\le x \le 9[/tex]
Thus we can say that the real numbers are 7, 8, and 9.

Suppose that the U.S. Government decides to charge cola producers a tax. Before the tax, 30 billion cases of cola were sold every year at a price of $4 per case. After the tax, 23 billion cases of cola are sold every year; consumers pay $5 per case, and producers receive $2 per case (after paying the tax).
Answer:
$3
$1
$2
False
Step-by-step explanation:
Here is the remaining part of the question :
The amount of the tax on a case of cola is per case. Of this amount, the burden that falls on consumers is per case, and the burden that falls on producers is per case. True or False: The effect of the tax on the quantity sold would have been larger if the tax had been levied on consumers. True False
A tax is a compulsory sum levied by the government or an agency of the government on goods or services.
Tax on a case of cola = Amount consumers pay - amount producers receive
= $5 - $2 = $3
Burden of tax on consumers = $5 - $4 = $1
Burden that falls on producers = $3 - $1 = $2
False. the incidence of tax is not dependent on who is taxed

Answer:
1. 1.96 g/L
2. 1 g/cm³
Step-by-step explanation:
Density is found by dividing mass by volume: d = m/v.
1.
We know that the mass is 0.196 grams, while the volume is 100 mL.
Converting the volume to liters, we get:
100 mL = 0.1 L
Then, applying our density formula:
d = m/v
d = 0.196 g / 0.1 L = 1.96 g/L
2.
Here, we know that the mass is 27 grams. However, we don't know the volume, which we need to find.
The block of wood is 3 cm on all sides, which means it's a cube. The volume of a cube is denoted by V = s³, where s is the side length. Here, s = 3, so V = s³ = 3³ = 27 cm³.
Applying our density formula gives:
d = m/v
d = 27 g / 27 cm³ = 1 g/cm³

3x + -18x + 26x + -11x
Answer:
0
Step-by-step explanation:
First, you have 3x and subtract 18x from it. This gives you -15x.
Then you have positive 26x, so you add 26x onto -15x.
After doing so, you have a positive 11x.
Now you need to subtract 11x from 11x.
Your final answer is 0! (No need to put x since it is just zero.)

Given the following roots x = 2, -3, 4. Write a polynomial function p(x)
Answer:
[tex]x^3-3x^2-10x+24[/tex]
Step-by-step explanation:
The first thing that you have to do is take the roots that you're given and write binomial products.
[tex]x= 2, -3, 4[/tex]
[tex](x-2)(x+3)(x-4)[/tex]
Remember that a root is the value of "x" in a binomial expression, so the binomial expression itself will have the opposite sign of the root.
The next thing you have to do is multiply the roots together. A good way to do this is the "box method."
(See attachment below for the multiplication of [tex](x-2)[/tex] and [tex]x+3[/tex]. )
Next, multiply your new trinomial by your remaining binomial. (See additional attachment below for the multiplication of [tex](x^2+x-6)[/tex] and [tex](x-4)[/tex])
The resulting polynomial is [tex]x^3-3x^2-10x+24[/tex].
