Write and solve an equation to find the number n. The difference of three times a number and 4 is -19.
Answer:
-5
Step-by-step explanation:
Let n be the unknown number
difference is subtraction
3n -4 = -19
Add 4 to each side
3n-4+4 = -19+4
3n = -15
Divide by 3
3n/3 = -15/3
n = -5

If -7.6(x - 1) = 7.3 - 7.4x, find the value of -2x.
Answer:
-3
Step-by-step explanation:
Step 1: Write equation
-7.6(x - 1) = 7.3 - 7.4x
Step 2: Solve for x
Distribute -7.6: -7.6x + 7.6 = 7.3 - 7.4x
Add 7.6x on both sides: 7.6 = 7.3 + 0.2x
Subtract 7.3 on both sides: 0.3 = 0.2x
Divide both sides by 0.2: x = 1.5
Step 3: Find -2x
-2(1.5) = -3
Answer:
3
Step-by-step explanation:
-7.6x+7.6=7.3-7.4x
-7.6x+7.4x=7.3-7.6
-0.2x=-0.3
X=-0.3/-0.2
X=3/2
2x. means multiply the ans you get for x by 2

Given the following expressions: A. 53 • 5–4 B. 3^5/3^-6 C.(1/4)^3 • (1/4)^2 D. (-7)^5/(-7)^7 Part 1: Use operations of exponents to simplify each expression (A-D). Include your work in your final answer. Part 2: For each simplified expression (A-D), tell whether or not the expression has a value between 0 and 1. Hint: Also this is a four part question. You have to give answers for A,B,C, & D.
Part 1:
A.53 =53
B.3^5/3^-6 =177147
C.(1/4)^3 • (1/4)^2 = 1 /1024
D.(-7)^5/(-7)^7 = 1/49
I tried my best for part 2 but i'm pretty sure it's not right. I think 1/1024 and 1/49 has a value between 0 and 1

Answer: 3.2 × 10^1
Step-by-step explanation:
When we multiply the same base we the exponents
Answer:
The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. In this example, you can see how it works. Adding the exponents is just a short cut! The "power rule" tells us that to raise a power to a power, just multiply the exponents.

Solve the equation for x. As you solve, justify the steps. Please help me out. -(3x - 12) = 9x - 4
Answer:
[tex]x=\frac{4}{3}[/tex]
Step-by-step explanation:
[tex]-\left(3x-12\right)=9x-4[/tex]
Distribute the negative sign to both 3x and -12:
[tex]-\left(3x\right)-\left(-12\right)=9x-4[/tex]
Remove brackets: (Double negative = Positive)
[tex]-3x+12=9x-4[/tex]
Subtract 12 from both sides:
[tex]-3x+12-12=9x-4-12[/tex]
[tex]-3x=9x-16[/tex]
Subtract 9x from both sides:
[tex]-3x-9x=9x-16-9x[/tex]
[tex]-12x=-16[/tex]
Divide both sides by -12:
[tex]\frac{-12x}{-12}=\frac{-16}{-12}[/tex]
[tex]x=\frac{4}{3}[/tex]

∠A and ∠B are vertical angles. If m∠A=(3x-30)° and m∠B=(2x-9)°,then find the value of x.
Answer:
x = 21°
Step-by-step explanation:
Vertical angles have the same measures, therefore:
3x - 30 = 2x - 9
x - 30 = -9
x = 21°

The amount of algae in a bloom, P, can be modeled by the equation P = t^4 + 6t^3+ 7t^2 + 8t, where t is measured in weeks. During what interval of t will the population of algae be greater than 500?
(−∞, −6.759) ∪ (3.452, ∞)

(0.3452, ∞)
(0, 3.452)
Answer:
C. (0.3452, ∞)
Step-by-step explanation:
The interval of t when the population of algae will be greater than 500 is (3.452, ∞)
What is an equation?"It is a mathematical statement which consists of equal symbol between two algebraic expressions."
For given question,
The amount of algae in a bloom, P, can be modeled by the equation [tex]P = t^4 + 6t^3+ 7t^2 + 8t[/tex] where t is measured in weeks.
We need to find the find the interval of t will the population of algae be greater than 500
So, we get an inequality,
[tex]\Rightarrow P > 500\\\\\Rightarrow t^4 + 6t^3+ 7t^2 + 8t > 500\\\\\Rightarrow t (t^3 + 6 t^2 + 7 t + 8) > 500\\\\\Rightarrow t [t [t (t + 6) + 7] + 8] > 500\\\\\Rightarrow t > 3.45~~and ~~t < -6.759\\\\[/tex]
But time is measured in weeks.
So, t will not have the values from the interval (−∞, −6.759)
Therefore, the interval of t when the population of algae will be greater than 500 is (3.452, ∞)
