Answer: The root of -4 is 2, and I'm not sure about 3
Step-by-step explanation:
is -5(x+8) equal to -5x-40 pleaseeee i need helppp
Answer:
yes
Step-by-step explanation:
The distributive property of multiplication over additions is:
a(b + c) = ab + ac
You multiply the number outside the parentheses, the a, by each of the numbers inside the parentheses, the b and the c. Then you add the products.
Now we can do it with your example.
-5(x + 8)
We multiply -5 by x and multiply -5 by 8. Then we add the products and simplify.
-5(x + 8) = -5 * x + (-5) * 8 = -5x + (-40) = -5x - 40

Answer:
the measure of the angle is 72
x=36
Step-by-step explanation:
we can make an algebraic equation using the info given
2x+80=152
2x=72
x=36
the measure of the angle is 72
Answer:
x = 36, the measure of the angle is 72
Step-by-step explanation:
We can see this because Angle 2x and Angle 72 are verticle angles. Based on this information we know that verticle angles are congruent to each other, meaning the are the same. So that leaves us with an equation to figure out x.
2x = 72
[tex]\frac{2x}{2}[/tex] = [tex]\frac{72}{2}[/tex]
x = 36

If 100 soldiers can eat 100 dozen rations in a week, how long will it take 400 soldiers to eat 400 dozen rations?
Answer:
1 week
Step-by-step explanation:
100 soldiers / 100 dozen = 1 soldier / 1 dozen
400 soldiers / 400 dozen = 1 soldier / 1 dozen
Therefore, it also takes a week for 400 soldiers to eat 400 dozen rations

Question 3:
Solve the inequality 3x – 8 > 16
Answer:
x is greater than 8
Step-by-step explanation:
3x-8>16
3x>24
x>8
The solution of the inequality is : x is greater than 8.
Here, we have,
given that,
the inequality 3x – 8 > 16
now, we have to Solve the inequality 3x – 8 > 16
so, we get,
3x-8>16
adding 8 on both side, we get,
=>3x>24
dividing both side by 3, we get,
=>x>8
Hence, The solution of the inequality is : x is greater than 8.

Determine the value of m∠DCB.
Answer:
Angle DCB is Equal to 78
Step-by-step explanation:
4x+2 + 3x+3 =180
7x +5=180
7x=175
x=25.
Then put the x in the 3x+3
3(25) +3 = 78
so DCB = 78

Given QUAD is a quadrilateral,
find the value of x.
If the answer is 14, move to J
If the answer is 30, move to L
If the answer is 23, move to K
If the answer is 21.4, move to M
Answer:
=>(4x+14)+(5x-1)+(4x-5)+(2x+7) = 360°
=>4x + 14 + 5x - 1 + 4x - 5 + 2x +7 = 360°
=>15x + 15° = 360°
=>15x = 360°- 15°
=>x = 345/15
=>x = 23
So move to K
Help I will be marking brainliest!!!!
A. 241 feet
B. 358 feet
C. 258 feet
D. 341 feet
Answer: A. 241 feet
Step-by-step explanation:
The figure shows two rectangular triangles.
These triangles are similar since they have two identical angles:
the first angle is 90 degrees;
the second angle is equal because the law of reflection states that the angle of incidence is equal to the angle of reflection.
The law of reflection states that the angle of incidence is equal to the angle of REFLECTION.
Let's make the proportion:
[tex]\dfrac{4}{273} =\dfrac{5}{x} \\\\x=\dfrac{273 \cdot 5}{4} =341.25 \: (feet)\\[/tex]
It takes a minimum of 100 feet for a parachute to open and safely land without injury, so:
341.25 - 100 = 241.25 (feet)
241.25 ≈ 241 (feet)

A car dealership buys a car for $12,500. They sell the car for $15,750. What is the percent markup?
Answer: 26%
Step-by-step explanation:
The formula to calculate the percentage markup is given as:
= Selling price - Cost / Cost price × 100
where selling price = $15750
Cost price = $12500
Percentage markup = ($15750 - $12500) / $12500 × 100
= $3250/$12500 × 100
= 26%
Answer: 26
Step-by-step explanation:
12,500 - 15,750= 3250
