Answer: x=16
Step-by-step explanation:
28= 8x + 12-7x
28= 8x-7x +12
28= x + 12
-12 -12
16= x
» The perimeter of a rhombus of side d cm
p cm, where p = 4d.
Find the perimeter of a rhombus of
side 3.2 cm.
Find the length of a side of a rhombus
of perimeter 14 cm.
Given:
The perimeter of a rhombus of side d cm is
[tex]p=4d[/tex]
To find:
The perimeter of a rhombus of side 3.2 cm.
Find the length of a side of a rhombus of perimeter 14 cm.
Solution:
Side of a rhombus is 3.2 cm. So, its perimeter is
[tex]p=4(3.2)[/tex]
[tex]p=12.8[/tex]
Therefore, the perimeter of a rhombus of side 3.2 cm is 12.8 cm.
The perimeter of another rhombus is 14 cm, and we need find its side.
[tex]p=4d[/tex]
[tex]14=4d[/tex]
Divide both sides by 4.
[tex]\dfrac{14}{4}=d[/tex]
[tex]3.5=d[/tex]
Therefore, the length of a side of a rhombus of perimeter 14 cm is 3.5 cm.

Simplify 7 square root of 3 end root minus 4 square root of 6 end root plus square root of 48 end root minus square root of 54 . (1 point)
11 square root of 6 end root minus 7 square root of 12
11 square root of 3 end root minus 7 square root of 6
negative 3 square root of 9
4 square root of 9
Answer:
1: 11√3 - 7√6
2: 11√3 - 7√6
3: -9
4:12
Step-by-step explanation:
To add radicals they need to have the same radical part for the first one we have
7√3- 4√6 + √48 - √54
We can simplify the last two into 4√3 and 3√6
So we have 7√3 - 4√6 + 4√3 - 3√6
adding similar radicals we get
11√3 - 7√6
For the second one we have 11√3 - 7√6
There's nothing we can do from here so keep that as your answer
This one is quite easy -3√9
square root of 9 is 3
so we have -3*3 which is -9
next is

p + 2q = 11
2p + q = 10
Answer:
p = 3
q = 4
Step-by-step explanation:
p + 2q = 11 --------------------(I)
p = 11 - 2q
2p + q = 10 --------------------(II)
Substitute p = 11 -2q in equation (II)
2(11 - 2q) + q =10
2*11 - 2q *2 + q = 10
22 - 4q + q = 10
22 - 3q = 10
-3q = 10 - 22
-3q = -12
q = -12/-3
q = 4
Plugin q = 4 in equation (I)
p + 2q = 11
p + 2*4 = 11
p + 8 = 11
p = 11 - 8
p = 3

Theo bought two hot dogs and two sodas for 4.00. At the same concession stand, Vicky bought three hot dogs and a soda for $4.50. What is the price of a hot dog at the concession stand?
А. $0.75
B. $1.00
C. $1.25
D. This question cannot be answered without more information.
Answer:
A. $0.75
Step-by-step explanation:
0.75×2=1.50 (1.50 price of 2 hotdogs)
4-1.50= 2.50 (2.50 is the price of 2 sodas)
1.50 + 2.50= $4
Identify the value of a if
y= a (x - 2) (2x + 4)
and the point (4,8) is on the graph.
Pls help fast
Answer:
a=1/3
Step-by-step explanation:
from the point on the graph
x=4 and y=8
substitute them into the equation:
y=a(x-2) (2x+4)
you will get
8=a(4-2) (2(4)+4)
8=a(2) (8+4)
8=a(2) (12)
8=2a×12
8=24a
divide both sides by 24
8/24=24a/24
1/3=a or a=1/3

Which of the following best describes the graph above?
A.
neither a relation nor a function
B.
function only
C.
relation only
D.
both a relation and a function
Answer:
Option C
Step-by-step explanation:
To test a graph whether it represents a function or relation we conduct a vertical line graph.
If the vertical line intersect the graph at two different points, graph represents a relation only.
By analyzing the given graph with the vertical line test,
Since, a vertical line (x = -4) intersect the graph at two points (y = -1 and y = 5),
Given graph represents a relation only.
Option C is the answer.

Factor the following polynomial completely
x^2-3x-10
I hope it will helps u
Step-by-step explanation:As given
x²-3x-10
Now according to the one of the rule of factorization ,
we have to find such two values whose product becomes equal to the
"product of first and last term " and if we sum those numbers it should be equal to the "middle term of it".
so such numbers are -5x and +2x
if we add or multiply them we get the above
as adding -5x+2x=-3x (middle term)
also multiplying -5x*2x=-10x² (product of 1st and last term)
so now , we can write as,
x²-3x-10
=x²-5x+2x-10
now making groups of 2 terms,
=(x²-5x)+(2x-10)
now common
=x(x-5)+2(x-5)
now common(x-5)
=(x-5)(x+2) This is the required factors.....
Mr. Johnson bought flowers to plant in flats in his yard. Each flat has 6 yellow flowers and 8 red flowers. Simplify the expression 6f+8f
Answer:
the simplified expression is 14f.
Step-by-step explanation:
Given expression;
6f + 8f
This expression is simplified by adding the two terms together since they are like terms.
6f + 8f = 14f
Therefore, the simplified expression is 14f.
Does Anyone know this answer:)
Answer: x = 10
Step-by-step explanation:
8x = 6x +20
2x = 20
X = 10
Check:
8(10) = 6(10) + 20
80 = 60 + 20
80 = 80
The polygons are similar. The area of one polygon is given. Find the area of the other polygon.
4 cm
12 cm
A = 10 cm
Area =
cm2
Answer:
90 cm²
Step-by-step explanation:
Given that both triangles are similar, it follows that the ratio of their area equals the square of their corresponding sides.
Let the area of the other triangle be x. Therefore:
[tex] \frac{10}{x} = \frac{4^2}{12^2} [/tex]
[tex] \frac{10}{x} = \frac{16}{144} [/tex]
Cross multiply
[tex] 10*144 = 16*x [/tex]
[tex] 1440 = 16x [/tex]
Divide both sides by 16
90 = x
Area of the other polygon = 90 cm²
Answer:
Answer is 90

The area of a rectangle is given by the expression XP-4x*+5x-2. The length of one side
of the rectangle is represented by the expression x-2. Which expression represents the
length of the other side?
1.
Answer:
Step-by-step explanation:
x2 + 5x + 4 (the area of the rectangle)
x + 2 (the length of one side)
(x2 + 5x + 4)/(x + 2)
do a division of this polynomial and you get; (x + 3) - 2/(x+2), you could leave the answer like this or you could simplify by using the LCM method
= [(x+2)(x+3) - 2]/(x + 2)
checking; (x + 2)*[(x+2)(x+3) - 2]/(x + 2) = (x+2)(x+3) - 2 = x2 +5x + 6 - 2 = x2 +5x + 4 (proven)

deb and luke go to the pi-rate entertainment store to purchase cds (c) and dvds (d). deb buys 3 dvds and 2 cds for $63 (before sales tax) at the same item prices, luke pays $46 for 1 dvd and 4 cds (before sales tax). write and solve a system of equations to determine the cost of 1 cd and dvd
We are given here the individual costs of DVD and CD as well as the total sales and the number of items sold on one day. To solve the number of DVDs and CDs sold each, we devise two independent linear equations:
(1) x + y = 39
(2) 4x + 7y = 204
x- number of DVDs; y - number of CDs
solving, x= 23 DVDs
