Answer:
x=0, y=-2
Step-by-step explanation:
Let x=3y+6 be equation 1
and 2x-4y=8 be equation 2
sub equation 1 into equation2,
2(3y+6)-4y=8
6y+12-4y=8
2y=-4
y=-2
sub y=-2 into equation 1,
x=3(-2)+6
x=0
sub is an abbreviation for substitute

Find the number if:
5/9 of it is 90.
And another similar question;
Find the number if:
7/3 of it is 5 5/6
I need help with both of these questions.
Answer:
162 and [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
To find the original number multiply by the reciprocal of the multiplier, that is
90 × [tex]\frac{9}{5}[/tex] = [tex]\frac{810}{5}[/tex] = 162
------------------------------------------------------------------------
Similarly
Change the mixed number into an improper fraction
5 [tex]\frac{5}{6}[/tex] = [tex]\frac{35}{6}[/tex] , then
[tex]\frac{35}{6}[/tex] × [tex]\frac{3}{7}[/tex] ( cancel 35 and 7 by 7 / cancel 6 and 3 by 3 )
= [tex]\frac{5}{2}[/tex] × [tex]\frac{1}{1}[/tex]
= [tex]\frac{5}{2}[/tex]
Answer:
162
Step-by-step explanation:
If it is 5/9 of the original number is 90 we can just divide 90 by 5 to find 1/9 and then we can multiply that with 9 to get 9/9 which is the whole number.
90 ÷ 5 = 18
18 × 9 = 162

helppppppp meeeee..........
Answer:
So the answer is zero slope, since the line is parallel to x-axis
Answer:
This slope is a horizontal slope which is also known as the slope of 0 because it has an infinite number of x values but just one y vale (in this case it is -1) .
I hope this helps :)
how to approximate to 3 significant figures
Answer:
We round a number to three significant figures in the same way that we would round to three decimal places. We count from the first non-zero digit for three digits. We then round the last digit. We fill in any remaining places to the right of the decimal point with zeros.
Which number is irrational?
A
B.
10
c.
716
D. V25
E. 36
Irrational is √10, because
√9 = √3² = 3
√16 = √4² = 4
√25 = √5² = 5
√36 = √6² = 36
We can't anything with √10, eventually we can approx.
Answer:
option a
Step-by-step explanation:
[tex] \sqrt{9 } = \sqrt{ {3}^{2} } = 3 \\ \sqrt{16 } = \sqrt{ {4}^{2} } = 4 \\ \sqrt{25} = \sqrt{ {5}^{2} } = 5 \\ \sqrt{36} = \sqrt{ {6}^{2} } = 6 \\ \sqrt{10} = \sqrt{2 \times 5} [/tex]
Hence, √10 is irrational number.

A. 13 units is the answer.
Steve buys last year's best-selling novel, in hardcover, for $22.50. This is with a 10% discount from the original price. What was the original price of the novel?
The original price of the novel is $25.
The summary are:
Steve bought the novel at $22.50 (including the discount)The discount given by the seller of the novel is 10%So, the original price will be computed as follows:
= $22.50 / (1 - 10%)
= $22.50 / 0.90
= $25
Therefore, the original price of the novel is $25.

A rectangular sticker has an area of 30 sq cm and it perimeter is 26 cm. what are the dimensions of the sticker?
#small Information
I know the equations but the problem I am not understanding it.. can you give a easier equations or method or more explanation of every equation..
Will give brainliest!!
Thank you :)
Answer:
Dimensions are 3cm and 10cm.
Step-by-step explanation:
We can make two equations for this problem.
ab = 30
2a + 2b = 26
Isolate a in the first equation.
a = 30/b
Plug that into the second equation.
2(30/b) + 2b = 26
2b^2 + 60 = 26b
2b^2 - 26b + 60 = 0
2(b - 3)(b - 10) = 0
b - 3 = 0 and b - 10 = 0
b = 3, 10
Plug these values into the first equation.
a3 = 30
a = 10
a10 = 30
a = 3
Best of Luck!
Name that polynomial X^4-3x^2+7x^5
We have that the Polynomial is named as a Quintic polynomial
From the Question we are told that
Polynomial=[tex]X^4-3x^2+7x^5[/tex]
We note that the Polynomial is of degree 5 as its highest Sum of its exponent is a
Quintic polynomial
Therefore
The Polynomial is named as a Quintic polynomial
In conclusion
For every Polynomial at degree five that is a greatest power of 5 (e^5) the accurate name for this polynomial is called a Quintic Polynomial

The Dallas Cowboys starting at the 20 yard line, ran two plays. The first play gained 10 yards, and after the second play the ball was placed at the 50 yard line. How many yards they gain on the second play?
=========================================================
Explanation:
They start on the 20 yard line. After the first play, they gain 10 yards and move to the 20+10 = 30 yard line.
After the second play, they must have gained 20 yards because 30+20 = 50.
Or you can think of it like 50-30 = 20, which shows the distance from the 30 yard line to the 50 yard line is 20 yards.
All of this assumes that the Cowboys started on their side of the field.

[tex]\\ \sf\longmapsto 4\dfrac{2}{5}[/tex]
[tex]\\ \sf\longmapsto \dfrac{5(4)+2}{5}[/tex]
[tex]\\ \sf\longmapsto \dfrac{20+2}{5}[/tex]

22/5
Explanation-
First, multiply 4x5, Then you get the product 20. With that 20, add with 2, so, 20+2=22. Now, place denominator as it is, then write 22 as numerator. So you get the answer as 22/5.
Working-
4×5=20
→ 20+2=22
→ 22
→ 22/5

Find the mean, median, mode, and range of the data set.
9, 3, 15, 7, 2, 4, 3
If necessary, round your answers to the nearest tenth.
Answer:
Step-by-step explanation:
Mean = Sum of data ÷ number of data set
[tex]=\dfrac{9+3+15+7+2+4+3}{7}\\\\=\dfrac{43}{7}\\\\= 6.14\\\\= 6.1[/tex]
Median:
Arrange the data in ascending order:
2 , 3 , 3 , 4 , 7 , 9 , 15
Middle term is the median of the data set
Median = 4th term = 4
Mode:
Mode is the data whose is frequency is more.
So, mode = 3
Range = Maximum - minimum
= 15 - 2
