Answer:
8x
Step-by-step explanation:
To do this we simply add the coefficients of x to give us our answer:
3 + 5 = 8
So our answer is 8x
One way to put this into perspective is to imagine x is the number of apples:
If you add 3 apples and 5 apples you get 8 apples.

2 1/2 dozen roses cost $40.50 what is the cost of a single rose
,
Answer:
$1.35
Step-by-step explanation:
=> No. of roses in a dozen = 12
=> No. of roses in half dozen = 12/2 = 6
=> No. of roses in 2 1/2 dozen = 2(12)+6 =30
=> 30 roses costs for $40.50
=> Cost of single rose = 40.5/30 = $1.35

Answer:
214°
Step-by-step explanation:
The external angle (marked 34°) is equal to half the difference of the arcs ACB and AB.
34° = 1/2(ACB -AB)
Together, the two arcs form a complete circle of 360°, so we have ...
34° = 1/2(ACB -(360° -ACB)) = 1/2(2ACB -360°)
34° = ACB -180° . . . . . . . . . . . . simplify
180° +34° = ACB = 214° . . . . . add 180°
The measure of arc ACB is 214°.
William transforms a figure by reflecting it over y=1 and then dilating it by a scale factor of 1/3 . What must be true of the image and the original figure?
1.They are similar but not congruent.
2.They are both congruent and similiar.
3.They are congruent but not similar.
4.They are neither similar or congruent.
Answer:
1.
Step-by-step explanation:
Reflection does not change the shape, just the orientation of the shape, also keeping the same size.
Dilation keeps the same shape, but changes the size.
same shape but different size is considered similar.

The dues in a neighborhood increased from $24 per month to $30 per month. Find the percent of increase.
Answer:
25%
Step-by-step explanation:
Think about it like this: $24 multiplied by how much equals $30?
This in equation form would be [tex]24x=30[/tex]
To solve for x, divide both sides by 24: [tex]x=30/24[/tex] or [tex]x=5/4[/tex]
5/4 in percentage form would be 125%, so the dues increased by 25%

A square has a perimeter of 12x 52 units. which expression represents the side length of the square in units? x 4 x 40 3x 13 3x 43
The expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.
What is the perimeter of a square?The measure of the boundary of the sides of a square is called its perimeter. The perimeter of a square is 4 times the side of the square.
[tex]P=4a[/tex]
Here, (a) is the side of the square.
A square has a perimeter of 12x +52 units. The perimeter of a square is 4 times the side of the square. Thus, the side of this square is,
[tex]P=4a\\12x +52=4a\\a=\dfrac{12x +52}{4}\\a=\dfrac{4(3x +12)}{4}\\a=3x+12[/tex]
Thus, the expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.

order 130 in, 4 yd in 10 ft from greatest to least
Answer: 4 yd, 130 in, 10ft
Step-by-step explanation:
So first you turn everything into inches
130 inches is already in inches.
4 yards = 12 ft
1ft = 12 in
12 *12 = 144 in
so 4 yards is 144 inches
10 ft = 12*10
12*10 = 120
so 10ft is 120 inches
144 inches is the greatest and 120 inches is the least.

A geometrical series have a constant ratio. The value of r is 4, while the value of a1 is 0.25 and the value of n is 5.
What is geometrical series?A geometrical series is a series of numbers where the quotient of any two consecutive terms of the series is constant.
The given series is a geometrical series which is given as, 0.25, 1, 4, 16, 64.
Now the value of r is the ratio of any two consecutive terms of the geometrical series therefore, the value of r can be written as,
[tex]r = \dfrac{1}{0.25}=4[/tex]
The a1 of a geometrical series is the first term of the series, therefore, the value of a1 can be written as,
a1 = 0.25
The n is the number of terms in a geometrical series, therefore, the value of n can be written as
n = 5
Hence, the value of r is 4, while the value of a1 is 0.25 and the value of n is 5.

the next model of a sport car will cost 14.9% more than the current model. The current costs $52,000. how much will the price increase in dollars ? what will be the price of the next model
Answer:
what will be the price of the next model= 59,748
Step-by-step explanation:
7748 is 14.9% of 52000
Solution:
What is 14.9% of 52000?
Y is 14.9% of 52000
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 14.9% * 52000
Converting percent to decimal:
p = 14.9%/100 = 0.149
Y = 0.149 * 52000
Y = 7748
To find the price for the next model
7748 + 52000
=> 59,748
