Betty correctly determined that the ordered pair (-3,5) is a solution to the system of linear equations 6x+5y = 7 and x + 4y = = 17. Based on this information, which statement is correct? O(-3,5) satisfies neither the equation 6x + 5y = 7 nor the equation x + 4y = 17. O(-3,5) satisfies the equation 6x + 5y = 7 but not the equation x + 4y = 17. O (-3,5) satisfies the equation x + 4y = 17 but not the equation 6x + 5y = 7. O(-3,5) satisfies both the equation 6x + 5y = 7 and the equation x + 4y = 17.
Answer:
(-3, 5) satisfies both the equation 6x + 5y = 7 and the equation x + 4y = 17.

Step-by-step explanation:
a wave has wavelength of 10m and a speed of 340m/s.what is frequency of the wave
340=10f.
frequency=34hertz.
Step-by-step explanation:
We have the wavelength which is 10,speed/velocity=340 and frequency=?.
The formula is velocity=frequency × wavelength.
340=f × 10.
340=10f.
frequency=34hertz.

A math test has 25 problems on it. If a student incorrectly answers 5 problems on the test,
what percentage of problems are correct? Be careful, reread the question.
(1 Point)
Answer:
i beleve they would get an 80% sorry if im wrong
Answer:
the answer is 80%
Step-by-step explanation:
Think of it this way
There is 5 problems wrong out of 25 so 5/25 is the fraction (right/ number of questions)
5/25 can be simplified to 1/5 (divide by 5)
1/5 can be transformed to the percentage 20%
NOW BE CAREFUL 20% is what is WRONG so 100-20=80
so 80% is thus the answer

A spinner has 20 total spaces that are either blue or red. The spinner is spun, and a die is rolled. If the probability of landing on a blue space AND a 3 is 10.83%, how many blue spaces are there on the spinner?
Answer:
Step-by-step explanation:
Remark
We have to assume that the die is a cube.
We know that getting a 3, if the die is fair, is 1 chance out of 6 = 1/6
We don't know how many blues there are on the spinner, but we do know that the number of them is over 20. So that's x/20
Now multiply the left side to get the combined probability. x/20 * 1/6. The result is 10.83/ 100
Solution
(x/20) * (1/6) = 10.83/100
x / 120 = 10.83/100 Multiply both sides by 120
x = 10.83 * 120 / 100
x = 12.996 which is going to round to 13
The blue spaces = 13

At present a women is twice as old as her daughter . Twenty one years ago she was three times older than her daughter . What is the women's present age?
Answer:
84 years
Step-by-step explanation:
Given :
At present :
Let :
daughter's age = x
Woman's age = 2x
21 years ago :
Woman's age = 3 times daughter's age
2x - 21 = 3(x - 21)
2x - 21 = 3x - 63
-21 + 63 = 3x - 2x
42 = x
Daughter's age = 42
Woman's age = 2x = 84
Hence, woman's present age is 42 years
Two expressions are shown below: A. 5(4 + 9) B. 29 + 36 Explain why Expression A is equivalent to Expression B. Use a property of operation in your answer.
Answer:
The two expressions A and B are equivalent because the value of both expressions is same.
Step-by-step explanation:
Given: Expression A is 5(4+9) and expression B is 29+36.
To find: The reason why expressions A and B are equivalent.
First we solve expression A.
[tex]5(4+9)=5*4+5*9[/tex] (using [tex]a(b+c)=a*b+a*c[/tex])
⇒[tex]5(4+9)=20+45[/tex]
⇒[tex]5(4+9)=65[/tex]
Now we solve expression B.
[tex]29+36=45[/tex]
Clearly, the value of both the expressions is same.
Hence, the expression A is equivalent to expression B.

Hey there!
The answer to your question is x = 7
We can solve this by simplifying both sides of the equation:
2x - 6 = 8x - 48
Then, add 48 to both sides:
2x + 42 = 8x
Then, subtract 2x from both sides:
42 = 6x
Lastly, divide both sides by 6:
7 = x

Find the measurement of the unknown angle
Answer:
The unknown angle is 65°
Step-by-step explanation:
Let the unknown angle be y
40°+75°+y = 180°
y = 180°-115°
y = 65°
Therefore, the unknown angle is 65°

The mistake begins at the line 3 where distrubting 2 in the expression. line 1 and line 2 both are correct. But line 3 is wrong.
[tex]2 {x}^{2} + 2x - 2 = 2 {x}^{2} - 18 \\ 2 {x}^{2} + 2x - 2 - 2 {x}^{2} + 18 = 0 \\ 2x - 2 + 18 = 0 \\ 2x + 16 = 0 \\ 2x = - 16 \\ x = - 8[/tex]
[tex]2( {x}^{2} - 9) = (2 \times {x}^{2} ) + (2 \times ( - 9)[/tex]
From line 3, you forgot to distribute 2 in -9.

A. 39.3
B. 34.5
C. 37.8
D. 35.9
Answer:
[tex]\mathrm{A.\: 39.3}[/tex]
Step-by-step explanation:
Let [tex]h[/tex] represent the height of the two smaller triangles in this figure. Because all three triangles are similar, we can set up the following proportion:
[tex]\frac{33}{h}=\frac{h}{y}[/tex], for [tex]y=x-33[/tex].
We can solve for [tex]h[/tex] using the Pythagorean theorem on the second largest triangle:
[tex]33^2+h^2=36^2,\\h=\sqrt{36^2-33^2},\\h=\sqrt{207}[/tex].
Now plugging in [tex]h=\sqrt{207}[/tex] into our proportion [tex]\frac{33}{h}=\frac{h}{y}[/tex], we can solve for y:[tex]\frac{33}{\sqrt{207}}=\frac{\sqrt{207}}{y}[/tex].
Cross-multiply to get:
[tex]33y=207,\\y=\frac{207}{33},\\y\approx 6.3[/tex].
Since we [tex]y=x-33, y+33=x[/tex].
Therefore, our answer is:
[tex]x=33+y=33+6.3=\fbox{$\mathrm{A.\: 39.3}$}[/tex].

My question is regarding cylinders plz.. Here it goes - a student winds a strip of paper eight times round a cylindrical pencil of diameter 7mm. Use the value 22/7 for π to find the length of the paper (ignore the thickness of the paper) pls I don't understand this .. Pls help
Answer:
176cm
Step-by-step explanation:
Step 1
We find the circumference of the cylinder
The formula for the Circumference = 2πr or πD
π = 22/7
Hence;
22/7 × 7
= 22
Since the strip of paper eight times round a cylindrical pencil of diameter 7mm, the length of the paper is calculated as: 22 × 8
= 176cm
