What is expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is an expression as -
5 - 3(x + 1) = 2y - 3x + 2
The given expression is -
5 - 3(x + 1) = 2y - 3x + 2
5 - 3x - 3 = 2y - 3x + 2
2 - 3x = 2y - 3x + 2
2 - 3x + 3x - 2 = 2y
2y = 0
y = 0
y = 0x + 0
Therefore, we can write the given equation in the form of y = mx + b as -
y = 0x + 0.

Ten baseballs and four ping-pong balls cost $46. One baseball costs one dollar more than two ping-pong balls. Find the cost of one baseball and the cost of one ping-pong ball.
Answer:
1 baseball cost $4
1 ping pong cost $1.5
Step-by-step explanation:
let the cost of baseball be b and the cost of ping pong be p
10 baseballs = 10b
4 ping pong = 4p
Adding both gives total $46
10b + 4p = 46 •••••••••(i)
baseball costs 1 dollar more than 2 ping pong
b = 2p + 1 •••••••(ii)
Substitute ii into i
10(2p + 1) + 4p = 46
20p + 10 + 4p = 46
24p = 46-10
24p = 36
p = 36/24
p = $1.5
b = 2p + 1
b = 2(1.5) + 1
b = 3 + 1 = $4

The area of a triangle is 10 square cm. The base is LaTeX: 2\:\frac{1}{2}2 1 2 cm. Find the height.
Answer:
[tex]Height = 40[/tex]
Step-by-step explanation:
Given
Shape: Triangle
[tex]Area = 10cm^2[/tex]
[tex]Base = \frac{1}{2}cm[/tex]
Required
Determine the height
Area of a triangle is calculated as:
[tex]Area = \frac{1}{2} * Base * Height[/tex]
Substitute values for Area and Base
[tex]10= \frac{1}{2} * \frac{1}{2}* Height[/tex]
[tex]10= \frac{1}{4}* Height[/tex]
Multiply both sides by 4
[tex]4 * 10= 4 * \frac{1}{4}* Height[/tex]
[tex]4 * 10= Height[/tex]
[tex]40= Height[/tex]
[tex]Height = 40[/tex]
Hence, the height is 40cm

The local newspaper has letters to the editor from 50 people. If this number represents 4% of all of the newspaper's readers, how many readers does the newspaper have?
Answer:
[tex]1250[/tex]
Step-by-step explanation:
Let the number of people that are readers of the newspaper be [tex]x[/tex]
[tex]50[/tex] people represents [tex]4\%[/tex] of all the reader of the newspaper.
This means
[tex]\dfrac{4}{100}\times x=50[/tex]
[tex]\Rightarrow x=50\times\dfrac{100}{4}[/tex]
[tex]\Rightarrow x=1250[/tex]
So, the number of readers the newspaper has is [tex]1250[/tex].

A certain radioactive substance decays from 100000 grams to 1000 grams in 34 days. What's it's half-life ?
Answer:
Half life of the radioactive element is 5 days.
Step-by-step explanation:
Formula to get the final amount after the radioactive decay in 't' days,
[tex]A_t=A_0e^{-\lambda t}[/tex]
Here [tex]A_0[/tex] = Initial amount
λ = Decay constant
t = duration of decay
[tex]A_t[/tex] = Final amount
[tex]1000=100000e^{-\lambda(34)}[/tex]
0.01 = [tex]e^{-34\lambda}[/tex]
ln(0.01) = [tex]\text{ln}(-e^{34\lambda}})[/tex]
-4.6052 = -34λ
λ = 0.13544
Since, λ = [tex]\frac{\text{ln}(2)}{t_{\frac{1}{2}}}[/tex]
[tex]t_{\frac{1}{2}}=\frac{\text{ln}2}{0.13544}[/tex]
= 5.11
≈ 5 days
Therefore, half life of the radioactive element is 5 days.
When a rocket is launched, it climbs 50 feet for every 13 feet it travels horizontally. Estimate the rocket's distance (Find the missing side of triangle).
Answer:
i don t this topic because i am the secundary
Step-by-step explanation:
.
The value of rocket's distance will be 51.66.
What is Pythagoras theorem?
The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.
Given that;
When a rocket is launched, it climbs 50 feet for every 13 feet it travels horizontally.
Now,
Since, When a rocket is launched, it climbs 50 feet for every 13 feet it travels horizontally.
And, The figure is shown the right triangle.
So, We can apply the Pythagoras theorem as;
⇒ x² = 50² + 13²
⇒ x² = 2500 + 169
⇒ x² = 2669
⇒ x = √2669
⇒ x = 51.66
Thus, The value of rocket's distance will be 51.66.

There are 4 colors of Starburst flavors: yellow, pink, red, and orange. If the probability of getting an orange is 2 5 2 5 , yellow is 1 10 1 10 , and the probability of getting red is 3 10 3 10 , what is the probability of getting pink?
Answer: 1/5
Step-by-step explanation:
From the question, we are informed that there are 4 colors of Starburst flavors: yellow, pink, red, and orange. We are further told that the probability of getting an orange is 2/5, yellow is 1/10 , and red is 3/10.
The probability of getting pink would be:
= 1 - [P(orange) + P(yellow) + P(red)]
= 1 - (2/5 + 1/10 + 3/10)
= 1 - (4/10 + 1/10 + 3/10)
= 1 - 8/10
= 2/10
= 1/5
