Use the model to solve for x. A) x = 1 B) x = 3 C) x = 5 D) x =
Answer:
D){?} x = 7Step-by-step explanation:
x + 3•(+1) = 2•x + 4•(-1)
x + 3 = 2x - 4
-3 -3
x = 2x - 7
-2x -2x
- x = -7
÷(-1) ÷(-1)
x = 7

Find the value of x in the triangle shown below help please!!
Step-by-step explanation:
Hey there!!
It 's so simple.
You remember common property of triangle. (i.e sum of interior angle of a triangle is 180°)
So,
77° + 31° + x = 180°
x + 108° = 180°
x = 180° - 108°
Therefore the measure of angle x is 72°.

Divide each side by
Divide each side by
Add 11 to each side.
Subtract 9 from each side.
2. Solve the equation. 10x + 2 = 32 x =
3. Solve the equation. 19 − 4c = 17 c =
4. solve the equation. 1.1x + 1.2x − 5.4 = −10 x =
6. solve the equation. 6(5 − 8v) + 12 = −54 v =
Answer:
Question: 1
Subtract 9 from each side.
Divide each side by 2
Add 11 to each side.
Divide each side by 4
Question: 2
10x +2 = 32
10x = 30
x = 3
Question: 3
19 -4c = 17
-4c = -2
c = 1/2 or 0.5
Question 4:
1.1x + 1.2x -5.4 = -10
2.3x = -4.6
x = -2
Question: 6
6(5 − 8v) + 12 = −54
6( 5 - 8v ) = -66
( 5 - 8v ) = -11
-8v = -16
v = 2

16) Amari ran three-quarter the distance Mary did. Amari ran 12 miles. Write and solve an equation that represents how far Mary
Answer:
Step-by-step explanation:
Amari ran 3/4 distance Mary ran
A = 3/4 M
Amari ran 12 miles
12 = 3/4 M Multiply by 4
12 * 4 = 3*M Combine
48 = 3M Divide by 3
48/3 = M
M = 16
So Mary ran 16 miles.

find the initial value seventeen years from now, Ms. speedis car, which is depreciating at 20% per year, will be worth $500
Answer:
Around 22200 dollars
Step-by-step explanation:
Firstly, it was depreciating 20% per year for 17 years. So, if we were to go back in time, it would be appreciating by 25%. Therefore, after doing the plugging in, it is 500 * 1.25^17. The initial value is around 22200. It is around 22204, to be exact.
Solve for h. -18+7h>12+9h
Answer:
[tex]h<-15[/tex]
Step-by-step explanation:
[tex]-18+7h>12+9h[/tex]
Add 18 to both sides:
[tex]-18+7h+18>12+9h+18[/tex]
[tex]7h>9h+30[/tex]
Subtract 9h from both sides:
[tex]7h>9h+30[/tex]
[tex]-2h>30[/tex]
Multiply both sides by -1 and flip the symbol:
[tex]\left(-2h\right)\left(-1\right)<30\left(-1\right)[/tex]
[tex]2h<-30[/tex]
Divide both sides by 2:
[tex]\frac{2h}{2}<\frac{-30}{2}[/tex]
[tex]h<-15[/tex]

Explain how solving -7y > 161 is different from solving 7y > -161
Answer:
Sample response:
Both inequalities use the division property to isolate the variable, y. When you divide by a negative number, like –7, you must reverse the direction of the inequality sign. When you divide by a positive number, like 7, the inequality sign stays the same. The solution to the first inequality is y > -23, and the solution to the second inequality is y <>

Step-by-step explanation:
The diagonal of a cube connects two opposite corners.
You can use the diagonal of a cube in a right triangle in which it is the hypotenuse. The legs of the triangle are a diagonal of a face and an edge.
Let the length of the edge be s.
a^2 + b^2 = c^2
[tex] s^2 + 10^2 = (\sqrt{150})^2 [/tex]
[tex] s^2 + 100 = 150 [/tex]
[tex] s^2 = 50 [/tex]
[tex] s = \sqrt{50} [/tex]
[tex] s = 5\sqrt{2} [/tex]
s = 7.1
Answer: 7.1 cm

For exercise 1-3 find the coordinates of the midpoint of the segment with each pair of end points (12,-7) and (-6,15)
Answer:
The answer is
( 3 , 2)Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(12,-7) and (-6,15)
The midpoint is
[tex]M = ( \frac{12 - 6}{2} , \: \frac{ - 7 + 15}{2} ) \\ = ( \frac{6}{2} \: , \: \frac{8}{2} )[/tex]
We have the final answer as
( 3 , 2)Hope this helps you

(3,-7) and (4,0) distance formula
Answer: approximately 7.07
Step-by-step explanation:
The distance formula is [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]. Since we are given teo points, we can plug them in and solve.
[tex]d=\sqrt{(4-3)^2+(0-(-7))^2}[/tex] [parenthesis]
[tex]d=\sqrt{(1)^2+(7)^2}[/tex] [exponent]
[tex]d=\sqrt{1+49}[/tex] [add]
[tex]d=\sqrt{50}[/tex] [square root]
[tex]d=7.07[/tex]
The distance is approximately 7.07.

We can write a ratio:
15/5 = 36/x
Let "x" equal the unknown part of the triangle.
Solution:
15/5 = 36/x
~Cross multiply
15x = 180
~Divide 15 to both sides
x = 12
Best of Luck!
