A store sold 7 white chairs for $148.75. How much 10 white chairs cost at the same unit price?
Answer:
212.5
Step-by-step explanation:
7 chairs = 148.75
148.75 ÷ 7 = 21.25
21.25 x 3 = 63.75
148.75 + 63.75 = 212.5
solve the equation -16(2x-8)-(18x-6)= -12+2(6x-6).
Consider the right triangle. What is the value of x
Answer:
X = 7
Step-by-step explanation:
180=90+4x+6+8x
84=12x
7=x
Answer:
x = 7
Step-by-step explanation:
The 3 angles in a triangle sum to 180°
sum the 3 angles and equate to 180
90 + 8x + 4x + 6 = 180 , that is
12x + 96 = 180 ( subtract 96 from both sides )
12x = 84 ( divide both sides by 12 )
x = 7

Write the equation in slope-intercept form of a line with slope -2 that passes through the point (1.-7)
Answer:
y=-2x-5
Step-by-step explanation:
y-y1=m(x-x1)
y-(-7)=-2(x-1)
y+7=-2x+2
y=-2x+2-7
y=-2x-5

9e + 4=-5e + 14 + 13e
Answer:
e= -10/9
Step-by-step explanation:
Answer:
e = 10
Step-by-step explanation:
1.) We need to manipulate the equation to get e by itself.
2.) To solve the equation, do the following steps;
9e + 4 = −5e + 14 + 13e
9e + 4 = 14 + 8e (Combine like terms)
9e + 4 − 8e = 14 + 8e − 8e (Subtract 8e from each side)
e + 4 = 14 (Combine like terms)
e + 4 - 4 = 14 - 4 (Subtract 4 from each side)
e = 10 (Combine like terms.
3.) Answer: e = 10.
Now lets check our work. To check your work, do the following steps;
9e + 4 = −5e + 14 + 13e
9e + 4 = 14 + 8e
9(10) + 4 = 14 + 8(10)
90 + 4 = 14 + 80
94 = 94
By doing those steps we can confirm the answer, e = 10, is true.

Which polygon has an interior angle sum of 1280º?
Answer:
3rd shape as it hase 9 sides
Step-by-step explanation:
1260/ 180 =7
7+2 = 9 sided shape
The polygon with 9 sides has an interior angle sum of 1280º.
Hence, option c is true.
We have to give that,
In a polygon an interior angle sum of 1280º.
We know that,
The formula for calculating the sum of interior angles is,
( n − 2 ) × 180°
where n is the number of sides.
Here, an interior angle sum of 1280º
Hence,
(n - 2) × 180° = 1280°
Divide both sides by 180°
(n - 2) = 1280/180
n - 2 = 7
n = 7 + 2
n = 9
So, The polygon with 9 sides has an interior angle sum of 1280º.

Simplify the Expression below 4+8+2−74x+8x+2x−7
A line passes through the point A (-2,-5) and has a slope of -9. Using the point-Slope formula, express the equation of the line in slope intercept form.
Answer:
y = -9x -23
Step-by-step explanation:
Point-slope formula gives you
y -(-5) = -9(x - (-2))
y + 5 = -9(x + 2)
y + 5 = -9x - 18
y = -9x -23

= 401.92 cm²
Midlle part = h * πd
= 6 * 3.14 * 16
= 301.44 cm²
Total = 401.92 + 301.44
= 703.36 cm²

If NML ~ SRL find the value of x.
Answer:
x = 5
Step-by-step explanation:
Since the triangles are similar, corrresponding sides are in proportion.
[tex]\frac{NM}{SR} = \frac{ML}{RL} = \frac{NL}{SL}[/tex]
Using the equation formed by the second and third fraction above we get
[tex]\frac{28}{24} = \frac{3x - 1}{x + 7}[/tex]
28(x + 7) = 24(3x - 1)
28x + 196 = 72x - 24
44x = 220
x = 5

I was wondering how can I find the length of a side from the angles given
Answer:
The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , is used to find the length of any side of a right triangle.
In a right triangle, one of the angles has a value of 90 degrees.
The longest side of a right triangle is called the hypotenuse, and it is the side that is opposite the 90 degree angle.
