Given:
A wire 45 meters long is cut into two pieces
One piece is 5 meters longer than the other.
To find:
The length of the two pieces.
Solution:
Let length of one piece be x.
One piece is 5 meters longer than the other. So,
Length of another piece = x+5
Total length of wire is 45. So,
[tex]x+(x+5)=45[/tex]
[tex]2x+5=45[/tex]
Subtract 5 from both sides.
[tex]2x=45-5[/tex]
[tex]2x=40[/tex]
Divide both sides by 2.
[tex]x=\dfrac{40}{2}[/tex]
[tex]x=20[/tex]
Now,
Length of one piece = 20 meters
Length of another piece = 20 + 5
= 25 meters
Therefore, the length of two pieces are 20 and 25 meters.

Answer:
See Explanation
Step-by-step explanation:
Since both the arcs centered at A and B are drawn as radius AB.
Therefore, AB = BC = AC
So, triangle ABC will be an equilateral triangle.
Since, AB = 5 CM
THEREFORE,
AC = 5 CM
BC = 5CM
Measure of each angle of equilateral triangle is 60°
Therefore,
Angle A = 60°
Angle B = 60°
Angle C = 60°
Valerie bought a guitar at a sale price of S = 0.8g, where g represents the original cost of the guitar. Which expression shows the sale price in a way that emphasizes the percent discount that she received? A S = (1 + 0.8). B S= (1 +0.2) g C S= (1 - 0.8). D S = (1 – 0.2) g
Answer:
D S = (1 - 0.2)g
Step-by-step explanation:
The original price of the guitar was g.
She paid 0.8g.
0.8g = 0.80g = 80% of g
If she paid 80% of the price, that means the discount was 20%.
100% - 20% = 1 - 0.2
Subtracting 20% form the whole 100% of the price is the same as subtracting 0.2 from the whole price of 1.
Answer: D S = (1 - 0.2)g

I have 1 word problem and a math problem. (word prob)A light-year is the distance that light travels in a year and is equivalent to 9.461 * 10^12. Write this distance in standard form.
(math prob) Order the list of numbers from least to greatest.
8.5*10^12,3.6*10^8,5.85*10^-3, 2.5*10^-1,8.5*10^8. ( This ^ means there are square roots for the numbers).
My math class is real soon. Pls, answer them. Thanks!!
Answer:
1. 9461000000000
move the desimal in 9.461 12 places to the right to get:
9461000000000
2.
5.85 x 10^-3,
2.5 x 10^-1,
3.6 x 10^8,
8.5 x 10^8,
8.5 x 10^12
the smallest exponent is the smallest. Since 8.5 x 10^8 and 3.6 x 10^8 have the same exponent, go to the desimal
3x + 7 <= 8x - 3

Solve for x: 9(x + 4) = 1 + 2x *
Answer:
x = -5
Step-by-step explanation:
9(x+4)=1+2x
9x+36 = 1 + 2x
35 = -7x
Divide
-5 = x
x= -5
[tex] \: \: \: \: \: \: \: 9(x + 4) = 1 + 2x \\ \\ = > 9x + 36 = 1 + 2x \\ \\ = > 9x - 2x = 1 - 36 \\ \\ = > 7x = ( - 35) \\ \\ = > x = (- \frac{35}{7} ) \\ \\ = > x = \green{\boxed{ - 5}}[/tex]
1/4 x 2 2/3, what is the product? (In fraction)
Answer:
8/12
Step-by-step explanation:
you want to write out your problem so it is
1/4 * 2 2/3
then you would want to change your 2nd fraction into an improper fraction (i think. i don't remember the correct term)
so you would multiply the denominator by the whole number on the side and then add the numerator to it
2 2/3 would them become 8/3 (you keep the denominator the same through the process)
so then you would multiply
1/4 by 8/3
multiply across and you get 8/12

So far this month Aaron calculated that he will earn $40 in commission for his $500 in product sales. If Aaron would like for his commission to be $320, how much will his product sales need to be?
Answer:
$4000 in product sales
Step-by-step explanation:
[tex]\frac{40}{500} =\frac{320}{x} = 4000[/tex]
Answer:
$4000
Step-by-step explanation:
i) Calculate if $1 = ? commission
500/40 = $12.5
$1 = $12.5 commission
ii) If the commission $320,
320×12.5=4000
His product sales need to be $4000

3, 4, 5, 6, 7 and 8 - total 6 numbersWhich equation is a line that passes through the points (4, 5) and (0, -3)?
Answer:
y = 2x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (4, 5) and (x₂, y₂ ) = (0, - 3)
m = [tex]\frac{-3-5}{0-4}[/tex] = [tex]\frac{-8}{-4}[/tex] = 2
The line crosses the y- axis at (0, - 3) ⇒ c = - 3
y = 2x - 3 ← equation of line

If m 3 = 74 degrees, find each measure
Answer:
A
Step-by-step explanation:
Answer:
m∠4 = m∠3 = 74° (vertically opposite angles are equal)
m∠8 + m∠3 = 180° (linear pair)
m∠8 + 74° = 180°
m∠8 = 180° - 74°
m∠8 = 106°
m∠7 = m∠8 = 106° (vertically opposite angles are equal)
m∠2 = m∠3 = 74° (alternate interior angles are equal)
m∠1 = m∠2 = 74° (vertically opposite angles are equal)
m∠6 + m∠1 = 180° (linear pair)
m∠6 + 74° = 180°
m∠6 = 180° - 74°
m∠6 = 106°
m∠5 = m∠6 = 106° (vertically opposite angles are equal)
