Answer:
-20
Step-by-step explanation:
a2 + ( b-c)
rewrite the equation
2 * a + ( b - c )
a = -8
b = 17
c = 21
substitute in the given values
(-8) 2 + ( (17) - (21) )
simplify and solve
-16 + ( 17-21)
= -16 + (-4)
= -16 -4
=-20

Answer:
ABC is congruent to A' B'C'
Step-by-step explanation:
All three sides are equal on triangle ABC and they are equal to the sides on A'B'C'
All three angles are equal on triangle ABC and they are equal to the angles on A'B'C'
We know that since the sides and the angles are equal
ABC is equal to A'B'C'
ABC is congruent to A' B'C'

Find the distance between points F(5, 3) and G(2, -7). Round to the nearest hundredth.
Answer:
10.44 units (nearest hundredth)
Step-by-step explanation:
Distance between 2 points
[tex] = \sqrt{(y1 - y2)^{2} + {(x1 - x2)}^{2} } [/tex]
Distance between F and G
[tex] = \sqrt{(3 - ( - 7))^{2} + (5 - 2)^{2} } \\ = \sqrt{ {(3 + 7)}^{2} + {3}^{2} } \\ = \sqrt{ {10}^{2} + 9 } \\ = \sqrt{109} \\ = 10.44 \: units \\ (nearest \: hundredth)[/tex]
-28 + 2x = -18 what is x?
Answer: x=5
Step-by-step explanation:
To solve for x, we want to use algebraic properties to isolate x.
-28+2x=-18 [add both sides by 28]
2x=10 [divide both sides by 2]
x=5
Now, we know that x=5.
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \text{x = 5}}}}}[/tex]
Step-by-step explanation:
[tex] \star{ \sf \: - 28 + 2x = - 18 }[/tex]
[tex] \tt{Step \: 1}[/tex] : Move 28 to right hand side and change it's sign
[tex] \hookrightarrow{ \sf{2x = - 18 + 28}}[/tex]
[tex] \tt{Step \:2}[/tex] : Subtract 18 from 28
The negative and positive integers are always subtracted but posses the sign of the bigger integer

[tex] \tt{Step \: 3}[/tex] Divide both sides by 2

-1/2x+3=-x+7 what does x equal
Answer:
x = 8
Step-by-step explanation:
-1/2x+3=-x+7
Add x to each side
-1/2x+x+3=-x+x+7
1/2x +3 = 7
Subtract 3 from each side
1/2x +3-3 = 7-3
1/2x = 4
Multiply each side by 2
1/2x *2 = 4*2
x = 8
Find the distance between each pair of points (-6,-10) , (-2,-10)
Answer:
4 units
Step-by-step explanation:
Use the distance formula, d = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex], where (x1, y1) and
(x2, y2) are 2 points
Plug in the points given
d = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]
d = [tex]\sqrt{(-6 + 2)^2 + (-10 + 10)^2}[/tex]
d = [tex]\sqrt{(-4)^2 + (0)^2}[/tex]
d = [tex]\sqrt{16 + 0}[/tex]
d = [tex]\sqrt{16}[/tex]
d = 4
So, the distance between the points is 4 units
The distance between each pair of points (-6,-10) , (-2,-10) is 4 units after using the distance formula.
What is a distance formula?It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.
The distance formula can be given as:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
It is given that:
The points are (-6,-10) , (-2,-10)
Using distance formula:
[tex]\rm d=\sqrt{(-2-(-6))^2+(-10-(-10))^2}[/tex]
d = √16
d = 4 units
Thus, the distance between each pair of points (-6,-10) , (-2,-10) is 4 units after using the distance formula.

A student has 2/3 quart of yellow paint in a container.The student uses 1/2 quart of the yellow paint to make green paint.How many quarts of yellow paint remains in the container after the student makes green paint?
Answer:
1/6
Step-by-step explanation:
2/3 - 1/2 = 4/6 - 3/6 = 1/6
1/6 quart remains.
Answer:
There are 1/6 quarts left in the container.
Step-by-step explanation:
You need to subtract 1/2 (the paint used) by 2/3 (the paint in the container)
First, find the LCD (lowest common denominator) if you want to subtract.
3 x 2 = 6; you do the same to the numerator 2 x 2 = 4
4/6 (paint in the container)
2 x 3 = 6; you do the same to the numerator 1 x 3 = 3
3/6 (paint used)
Now, you subtract.
4/6 - 3/6 = 1/6 quarts
