Answer:
Step-by-step explanation:
I think that Percents are used very commonly all around us every day. It gives us a better vision in our mind of the quantity than decimals or fractions. We see Percents everywhere. In the shopping mall for discounts, math homework and work. So overall, percents are most commonly used.
Hope that helps!

HELP EMERGENCY, I'll give brainiest
-1/2d + 3/8 - d = 1/4 + 3/4d +2
First combine like terms on both sides:
-1 1/2d + 3/8 = 2 1/4 + 3/4d
Add 1 1/2d to both sides:
3/8 = 2 1/4 + 2 1/4d
Subtract 2 1/4 from both sides:
-1 7/8 = 2 1/4d
Divide both sides by 2 1/4:
d = -5/6
[tex] \huge \boxed{\mathbb{QUESTION} \downarrow}[/tex]
[tex] \tt- \frac{ 1 }{ 2 } d+ \frac{ 3 }{ 8 } -d = \frac{ 1 }{ 4 } + \frac{ 3 }{ 4 } d+2 \\ [/tex][tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
[tex] \tt- \frac{ 1 }{ 2 } d+ \frac{ 3 }{ 8 } -d = \frac{ 1 }{ 4 } + \frac{ 3 }{ 4 } d+2 \\ [/tex]
Combine [tex]\tt-\frac{1}{2}d[/tex] and -d to get [tex]\tt-\frac{3}{2}d[/tex].
[tex] \tt-\frac{3}{2}d+\frac{3}{8}=\frac{1}{4}+\frac{3}{4}d+2 \\ [/tex]
Because 1/4 and 8/4 have the same denominator, add them by adding their numerators.
[tex] \tt-\frac{3}{2}d+\frac{3}{8}=\frac{1+8}{4}+\frac{3}{4}d \\ [/tex]
Subtract [tex]\tt\frac{3}{4}d[/tex] from both sides.
[tex] \tt-\frac{3}{2}d+\frac{3}{8}-\frac{3}{4}d=\frac{9}{4} \\ [/tex]
Combine [tex]\tt-\frac{3}{2}d[/tex] and [tex]\tt-\frac{3}{4}d[/tex] to get [tex]\tt-\frac{9}{4}d[/tex].
[tex] \tt-\frac{9}{4}d+\frac{3}{8}=\frac{9}{4} \\ [/tex]
Subtract 3/8 from both sides.
[tex] \tt-\frac{9}{4}d=\frac{9}{4}-\frac{3}{8} \\ [/tex]
The least common multiple of 4 and 8 is 8. Convert 9/4 and 3/8 to fractions with denominator 8.
[tex] \tt-\frac{9}{4}d=\frac{18}{8}-\frac{3}{8} \\ [/tex]
Because 18/8 and 3/8 have the same denominator, subtract them by subtracting their numerators.
[tex] \tt-\frac{9}{4}d=\frac{18-3}{8} \\ [/tex]
Subtract 3 from 18 to get 15.
[tex] \tt-\frac{9}{4}d=\frac{15}{8} \\ [/tex]
Multiply both sides by - 4/9, the reciprocal of -9/4.
[tex] \tt \: d=\frac{15}{8}\left(-\frac{4}{9}\right) \\ [/tex]
Multiply 15/8 by -4/9 by multiplying the numerator by the numerator and the denominator by the denominator.
[tex] \tt \: d=\frac{15\left(-4\right)}{8\times 9} \\ [/tex]
Carry out the multiplications in the fraction ⇨ [tex]\tt\frac{15\left(-4\right)}{8\times 9}[/tex].
[tex] \tt \: d=\frac{-60}{72} \\ [/tex]
Reduce the fraction -60/72 to its lowest terms by extracting and cancelling out 12.
[tex] \boxed{ \boxed{ \bf \: d=-\frac{5}{6}\approx -0.833..}}[/tex]

Recall that the sum of the angle measures of a triangle is 180. Find the measures of the angles of a triangle if the measure of one angle is twice the measure of a second angle and the third angle measures 4 times the second angle decreased by 100.
The measure of the three angles are
Answer:
40 (angel 1), 80 (angel 2), 60 (angel 3)
Step-by-step explanation:
180= 2x + x + 4x - 100
180 + 100 = 2x + x + 4x
280 = 7x
280/7 = x
40 = x

Answer:
2) Right angles always equal 90°
3) m∠F = 90° and m∠G = 90° which means they have the same angle measure.
4) Removing the m and replacing with the congruent symbol.

Which graph represents the inequality y>1-3x
Answer:
b............ .......... which one is a b c d
For this case we must indicate the graph of the following inequality:
y≥1−3x
It is observed that inequality includes equality, so the boundary line of the graph will not be dotted, so we discard options D and C.
We test option A, we substitute the point (0,0) in the inequality, if it is fulfilled then the graph corresponds to it.
We test option A, we substitute the point (0,0) in the inequality, if it is fulfilled then the graph corresponds to it.
It is not fulfilled
We test the last option B, we choose the point (3,1) that belongs to the graph:
1≥1−3(3)
\1≥1−9
1≥−8
it is fulfilled
Answer:
The correct answer is c - the top part is shaded in and the line is DOTTED

Martin was 10 years old last year. This year, His brother's age is 2 times of Martin's. How old is Martin's brother this year?
x=-4 +6+ (11 +4(-3))
Answer:
x=1
Step-by-step explanation:
x = -4 + 6 + (11 + 4(-3)).
First get the numbers in the parentheses
x = -4 + 6 + (11 - 12)
Since 11 - 12 = -1. We can replace (11-12) with -1
x = -4 + 6 -1
Now add and subtract
x = 1

A. What do you know?
length = 25 cm, width = 18 cm, height = 10 cm
B. What do you want to find? Volume
Answer:
4500cm^3
Step-by-step explanation:
To find the volume multiply the length × width × height
25×18×10=4500
Answer:
4,500 cm³.
Step-by-step explanation:
Since L × W × H = V(olume), we get 25 × 18 × 10 which equals 4,500 cm³.
