Answer:

7.7% decrease in the value of the moped

Step-by-step explanation:

Bree bought a 1994 moped for $3,500

A year later the value of the moped dropped to $2,730

Therefore the percent of decrease of the value of the moped can be calculated as follows

= 3,500-2,730/100

= 770/100

= 7.7 % decrease

Hence there was a 7.7% decrease in the value of the moped

Answer:

Answer:

25 and29

Step-by-step explanation:

let x be one number

then according to questions another number will be x+4

we can write

x+x+4=54

2x=54_4

2x=50

x=50/2

x=25

one number is 25 and another number is 25+4=29

Answer:y=x/3

Answer:

uhm -7?

Step-by-step explanation:

374 ÷ (x - 10) = -22

374 = -22(x - 10)

374 = -22x + 220

374 - 220 = -22x

154 = -22x

154 ÷ -22 = x

-7 = x

Answer:

20 students should be on each float

Step-by-step explanation:

Number of seniors = 100

Number of juniors = 80

To find number of students that should be on each float, find highest common factor (H.C.F) of 100 and 80

Write prime factorisation of 100 and 80.

100 = [tex]2^2[/tex] × [tex]5^2[/tex]

80 = [tex]2^4[/tex] × 5

So,

H.C.F(100, 80) = [tex]2^2[/tex] × 5 = 4 × 5 = 20

Therefore,

20 students should be on each float

Answer:

The meaning of rigid corresponds with rigid motion

Step-by-step explanation:

Rigid motion in geometry occurs when a point or object is moved, but the size and shape remain the same. It is also referred to as RIGID TRANSFORMATION.

Therefore, the meaning of the word rigid, which means "not bendable", and another is "unable to be changed" corresponds to the definition of rigid motion.

Rigid means unable to move or remain stagnant.

Answer:

$42

Step-by-step explanation:

5 divided by $30 so each ticket would be $6 then just multiply $6 and 7

Answer:

It would cost $42 because 30 divided by 5 equals 6, so that's saying for each  1 ticket it costs $6. So with the new equation, 7 x $6, we get $42. Which will end up being the cost for 7 tickets.

Answer:

x + 4

Step-by-step explanation:

Area of rectangle= length × breadth

In this question, one length is 5x + 3 and the area is 5x^2 + 23x + 12

This means that;

5x2 + 23x + 12 = 5x + 3 (b)

Hence, to get the other length (b) = 5x2 + 23x + 12/ 5x + 3

To get the other length, we can factorize the algebraic expression;

5x2 + 23x + 12

Product: 60x^2 (20x × 3x)

Sum: +23x (20x + 3x)

Hence;

= 5x^2 + 20x + 3x + 12

Next, we find factors;

5x (x+4) + 3 (x+4)

Therefore, the factors are (5x + 3) and (x +4)

This means that the other length is (x +4)

Answer:

original price = 35

new price = 35 - 85%*35 = 35 - 29.75 = 5.25

Step-by-step explanation:

Answer:

y=3/2x-4

Step-by-step explanation:

3x-2y=8

-2y=-3x+8

y=3/2x-4

y=3/2x-4

3x-2y=8

-2y=3x+8

y=3/2x-4

Answer: 9

Step-by-step explanation: on a number line -9 is before 0 9 is after 0 , and any number to the right of a number is greater.

Answer:

i tried to find the answer but its not working for me... hold on imma try again

Step-by-step explanation:

Answer:

a = -2

Step-by-step explanation:

7a + 10 = 2a​

subtract 2a from both sides

5a + 10 = 0

subtract 10 from both sides

5a = -10

divide both sides by 5

a = -2

Answer:

-6

Step-by-step explanation:

First you need to substitute -1 in for x in -2x^2

This makes it (-2)(-1)^2

-2x^2 becomes -2 so this means that the equation is now

-2 + (-1) - 3

-2 + (-1) = -3

-3 - 3 = -6

Answer: First, remember that parallel lines have the same slope. So we first need to find the slope of the line we are given, 3x+2y=27. The quickest way to find the slope of this line is to put it into slope-intercept form (y=mx+b)

subract 3x from both sides:  

2y=-3x+27

divide each term by 2:

y=-3/2x +27/2

Now we can see that the slope is -3/2.

From here, we use the slope we found and the ordered pair given (7,-4) and find the equation of the new line. We will have to use point-slope form (y-y1)=m(x-X1) to find the new line because the ordered pair given is not the y-intercept.

(y-(-4))=-3/2(x-7)

distribute -3/2:

(y-(-4))= -3/2x + 21/2

simplify double negative on left side of equals sign:

y+4=-3/2x + 21/2

Subtract 4 from both sides:

y= -3/2x + 13/2

This is your answer in slope intercept form. Because the directions specifically ask for standard form, we have one more step. Standard form (ax+by=c) needs the terms with x and y to be on the same side of the equals sign. So, we simply have to move the term with x (-3/2x) to the other side by adding.

Finished product:

3/2x+y= 13/2
