If 5 people are going to share
11.8 ounces of cheese, how
much will each person get?
Answer:
2.36 ounces
Step-by-step explanation:
11.8 ounces / 5 people = 11.8/5 = 2.36 ounces each.
Answer:
2.36 oz
Step-by-step explanation:
To answer this, we need to divide 11.8 oz by 5.
11.8/5 = 2.36
So each person gets 2.36 ounces of cheese
solve using substitution
-5x+7y=-5
y=-5
x=?
So if you solve for x using the first equation, you get: x = 5y - 5.
From there you can plug that into the second equation which would give you:
7y-5y+5=-23
Simplifying from that point, you get y = -9.
Now that you have one of the values, you can solve for x by plugging it back into the equation we made (x = 5y - 5) and getting to the answer x = -40.
Solve using substitution. y = 1
3x − 7y = 8
Answer:
(5, 1)
Step-by-step explanation:
Substitute:
[tex]3x - 7*1 = 8\\3x - 7 = 8\\3x = 15\\x = 5[/tex]
so the solution is (5, 1)
What is x?
(4/5)^x=64/125
Answer:
x = 3
Step-by-step explanation:
(4/5)^x = 64/125 means that 4^x / 5^x = 64/125
x can only be 3 because 4^3 = 64 and 5^3 = 125

The value of Sin 2x if, Sin x = 2 / 5 and tan(x) > 0, is 4 √21 / 25 so, option B is correct.
What is trigonometry?Trigonometry is the branch of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine, cosine, and tangents are their names and acronyms (tan).
Given:
Sinx = 2 / 5 and tan(x) > 0,
Calculate the value of tan x as shown below,
B² = 5² - 2² (Using Pythagoras theorem)
B² = 25 - 4
B = √21
Hence, Tan x = 2 / √21
Calculate the value of Sin 2x as shown below,
Sin2x = 2 Tan x / (1 + tan² x)
Sin2x = 2 × 2 / √21 / (1 + (2 / √21)²)
Sin2x = 4 / √21 / (1 + 4 / 21)
Sin2x = 4 / √ 21 / (25 / 21)
Sin2x = 4 √21 / 25
Thus, the value of Sin2x is 4 √21 / 25.

Find the value of X.
Answer:
19) 28°
20) 60°
21) 17°
Step-by-step explanation:
19)
Supplementary angles:
(x + 12)º + 140º = 180º
x + 12 + 140 = 180
x = 180 - 140 - 12
x = 28º
20)
Angles at a point:
(- 24 + x)° + 24° + 300° = 360°
- 24 + x + 24 + 300 = 360
x = 360 - 300
x = 60°
21)
Vertically opposite angles:
(1 + 3x)° = 52°
1 + 3x = 52
3x = 52 - 1
3x = 51
x = 17°
can someone please help me with number one asap!!
Answer:
a = 60
b = 60
c = 120
Step-by-step explanation:
For a;
a + 120 = 180
This is because angles on a straight line are supplementary
a = 180-120
a = 60
a = b = 60
This is because they are corresponding angles and corresponding angles are equal
c = 120
This is because they are alternate exterior angles and alternate exterior angles are equal

12x -20=n (3x-5)
I need help I don’t get it please help me.
Answer:
The value of n = 4 and
The value of x = [tex]\frac{5}{3}[/tex]
Step-by-step explanation:
Method I:
As given, 12x -20=n (3x-5) .........(1)
Firstly , take 12x - 20
As 12x - 20 can be written as 4(3x - 5)
∴ equation (1) becomes
4(3x - 5) = n (3x-5)
Divide the equation by (3x-5) , we get
4 = n
Method II:
As given, 12x -20=n (3x-5)
⇒12x - 20 = 3nx - 5n
⇒12x - 3nx = 20 - 5n
⇒3x(4 - n) = 5( 4 - n)
Divide the equation by (4-n) , we get
3x = 5
⇒ x = [tex]\frac{5}{3}[/tex]
∴ we get
n = 4 and x = [tex]\frac{5}{3}[/tex]
Now, check that value of n and x satisfies the equation or not
12([tex]\frac{5}{3}[/tex]) - 20 = 4( 3([tex]\frac{5}{3}[/tex]) - 5)
⇒4(5) - 20 = 4(5 - 5)
⇒20 - 20 = 4(0)
⇒ 0 = 0
Hence , we get
The values of x and n satisfies the equation
so, we get
n = 4 and x = [tex]\frac{5}{3}[/tex]

Pls helpppp
Answer:
Infintely many solutions
Step-by-step explanation:
I'm going to assume that the capital y is equal to the lowerase y
if you subtract y and two from both sides in the second equation you get
-y=2x-2
you then divide by -1 to get it into a normal form
y= -2x+2
this is the same as the first equation, these lines are the same
Identify the zeros of each function. y=(x-7)^2
9514 1404 393
Answer:
x = 7 (multiplicity 2)
Step-by-step explanation:
When the function is written in factored form, the zeros are the values of the variable that make the factors zero.
y = (x -7)(x -7)
The values x = 7 and x = 7 will make the factors zero. The zero is said to be x=7 with multiplicity 2.

On the graph, the zeros are the x-intercepts (where y=0). The graph only touches the x-axis, but does not cross. With some experience, you can recognize that this is a zero with even multiplicity (2).

Kara bought two birthday gifts for her twin nephews. Each gift cost $12.50. Sales tax was
8.5%. What was the total cost for the gifts, including tax?
Answer:
$27.12
Step-by-step:
So, we first need to learn how much money the tax is. We can find it like this
8.5 8.5x12.50
------ x 12.50 = ----------------
100 100
106.25
= ------------- = 1.0625 ~~ $1.06
100
The tax is $1.06
So now, the only thing left is to add
12.50 + 1.06 = $13.56
13.56x2 = $27.12 (for both gifts)
In total, both gifts cost $27.12 with tax.
In total, both gifts cost
