Answer: 7.3
Step-by-step explanation:
Do the parentheses first!
4-7= -3
Then, multiply -3 by 2
-3×2= -6
Next,
-6-6.7= -12.7
Then, add -12.7 to 20
-12.7+20=7.3
Your answer is 7.3

Is EF and GH parralel and how can this be determined?
Answer:
We have slope of EF : [tex]\mathbf{\frac{-4}{5}}[/tex] and slope of GH: [tex]\mathbf{\frac{-4}{5}}[/tex]
Both have same slope, so EF is parallel to GH i.e. EF || GH
Step-by-step explanation:
We need to find Is EF and GH parallel.
If EF and GH are parallel, they have same slopes.
So, we will find slopes of EF and GH
The formula used is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of EF
We have: E(2,5) and F(7,1)
So, [tex]x_1=2, y_1=5, x_2=7, y_2=1[/tex]
Putting values in formula and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{1-5}{7-2}\\Slope=\frac{-4}{5}\\[/tex]
So, slope of EF is [tex]\mathbf{\frac{-4}{5}}[/tex]
Slope of GH
We have: G(2,-3) and F(-3,5)
So, [tex]x_1=2, y_1=-3, x_2=-3, y_2=5[/tex]
Putting values in formula and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{5-(-3)}{-8-2}\\Slope=\frac{5+3}{-10}\\Slope=\frac{8}{-10}\\Slope=\frac{-4}{5}[/tex]
So, slope of GH is [tex]\mathbf{\frac{-4}{5}}[/tex]
We have slope of EF : [tex]\mathbf{\frac{-4}{5}}[/tex] and slope of GH: [tex]\mathbf{\frac{-4}{5}}[/tex]
Both have same slope, so EF is parallel to GH i.e. EF || GH

What is the value of x in simplest radical form?
H is correct one!!
By Pythagoras theorem
H² = B² + A²
H= 9
B= x
A = 3
Now
9² = 3² + x²
9² - 3² = x²
72 = x²
√72 = x
Sarah colored 1/2 of some birthday cards, and Rana colored 3/8 of them. If there are 32 cards in all, how many are left to be colored?
Answer: 4 cards are left to be colored.
Step-by-step explanation:
As per given,
Fraction of total cards colored = [tex]\dfrac12+\dfrac38[/tex]
[tex]=\dfrac{4+3}{8}\\\\=\dfrac{7}{8}[/tex]
Fraction of cards left to be colored = [tex]1-\dfrac78=\dfrac18[/tex]
Total cards = 32
Number of cards to be colored = [tex]\dfrac18\times32=4[/tex]
Hence, 4 cards are left to be colored.

Write an equation of the line with a slope of 2/3
and y -intercept of -8
Answer: y= 2/3 + -8
Step-by-step explanation: Put into slope intercept form
The equation of the line with a slope of 2/3 and y -intercept of -8 is y = 2/3 x -
8
The slope intercept equation is represented as follows:
y = mx + b
where
m = slope
b = y-intercept
Therefore,
The equation of the line has a slope(m) of 2 / 3 and y-intercept of -8.
The equation can be represented as follows:
y = 2/3 x - 8

As is often the case with multiple choice questions, you only need to identify a feature of the answer set that distinguishes right from wrong. Here, that can be the lowest-power term, which is always the product of the lowest-power terms.
That product is (-3m)(+m) = -3m². This matches the third answer choice.

Answer:
x = 2
Step-by-step explanation:
Given
- 2(1 - 4x) = 3x + 8 ← distribute left side
- 2 + 8x = 3x + 8 ( subtract 3x from both sides )
- 2 + 5x = 8 ( add 2 to both sides )
5x = 10 ( divide both sides by 5 )
x = 2
