Answer:
Step-by-step explanation:
Perimeter of a rectangular wall P = 2L+2W
L is the length of the wall
W is the width
Given
P = 148feet
If the width is two more than seven times the length, this is represented as
W = 7L+2
Substitute W = 7L+2 into the formula above
P = 2L + 2(7L+2)
P = 2L +14L+4
P == 16L+4
148 = 16L+4
16L = 148-4
16L = 144
L = 144/16
L = 9
To get the width
W = 7L+2
W = 7(9)+2
W = 63+2
W = 65feet
Hence the width of the rectangular wall is 65feet

-(3x + 17)
Answer:
17rx2−23rx−71x+75
Step-by-step explanation:
(17x−23)(xr−4)−(3x+17)
=(17x−23)(xr−4)+−1(3x+17)
=(17x−23)(xr−4)+−1(3x)+(−1)(17)
=(17x−23)(xr−4)+−3x+−17
=(17x)(xr)+(17x)(−4)+(−23)(xr)+(−23)(−4)+−3x+−17
=17rx2+−68x+−23rx+92+−3x+−17
=17rx2+−68x+−23rx+92+−3x+−17
=(17rx2)+(−23rx)+(−68x+−3x)+(92+−17)
=17rx2+−23rx+−71x+75

For a quadrilateral to be rhombus the diagonals have to be
Answer:
perpendicular bisectors of each other
Step-by-step explanation:
For a quadrilateral to be rhombus the diagonals have to be perpendicular bisectors of each other.
__
The diagonals of a parallelogram bisect each other. When that parallelogram is a rhombus, the diagonals are perpendicular, hence mutual perpendicular bisectors.

144kg in the ratio of 9:8:7
Step-by-step explanation:
Hey there!
Given;
Ratio = 9:8:7
Let "x" be the common factor. So,
9x+8x+7x = 144
or, 24x = 144
or, x = 144/24
or, x= 6
It's like;
= 9*6:8*6:7*6
= 54:48:42
Therefore, their ratio is 54:48:42.
Hope it helps...

Four friends were making cards to sell at the holiday sale. Each friend made 9 cards. They put all their cards together and then bundled them in groups of 6 cards to sell. How many bundles of 6 cards did they make? Show all your work.
Answer:
6 bundles
Step-by-step explanation:
4 friends each made 9, so you multiply 4*9 to get 36
each bundle has 6, so divide 36 by 6. and get 6 bundles.
4*9=36
36/6=6
Answer:
they made a total of 6 bundles
Step-by-step explanation:
4×9=36
36÷6=6
Three times a number, increased by one, is between negative eleven and seven. Find all the numbers
Answer:
7 < 3N+1 < 11
6 < 3n < 10
2 < n < 10/3
Step-by-step explanation:
The required number is -3, -2, -1, 0, and 1 which is three times a number, increased by one, is between negative eleven and seven.
Given that,
Three times a number, increased by one, is between negative eleven and seven. the number is to be determined.
Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
here,
Accoding to the condition let the number be x,
and
-11 < 3x + 1 < 7
-12 < 3x < 6
-4 < x < 2
So the number are -3, -2, -1, 0, anb 1
Thus, the required number is -3, -2, -1, 0, and 1 which is three times a number, increased by one, is between negative eleven and seven.

if ta=16 & mh= 18 what is the lenth of mr?
Answer:
the length of MR = 9
Step-by-step explanation:
Looking at the figure, we can tell that segment TR is congruent to segment RA, meaning TR has equal length to RA and the same goes to MR and RH. Since the problem gives us the total length of line TA and line MH, we can say that the length of MR is half of the total length of MH. Therefore, length of MR is 9.
A job posting is searching for runway models to walk in a designer fashion show. The posting states that the preferred model should be no more than 2 inches away from being 5 feet 11 inches. Write and solve an absolute value inequality that can be used to determine the height range, in inches, of a preferred model. Graph the solution set on a number line.
Answer:
70 ≤ x ≤ 74
Step-by-step explanation:
5 feet 11 inches = (5 x 12 inches) + 11 inches
= 72 inches
Since the preferred model should not be no more than 2 inches away from 72 inches, then;
72 inches ± 2 inches
Let the required height be represented by x, the absolute value inequality is;
lx ± 2l ≤ 72
x + 2 ≤ 72
x ≤ 72 - 2
x ≤ 70
Also,
x - 2 ≤ 72
x ≤ 72 + 2
x ≤ 74
Therefore, the preferred height range in inches is;
70 ≤ x ≤ 74
The graph is herewith attached to this answer.

A recipe calls for 2 1/3 cups of flour, cups of white sugar, and cups of brown sugar. The recipe makes 6 servings.
How many cups of flour are there per serving?
Suppose you modify the recipe to triple the number of servings. How much flour do you need for the modified recipe? [PS]Can you show my how its done too?
Answer:
Lets find how much flour we need for just one serving.
2 2/3 ÷ 6
8/3 ÷ 6
8/3 * 1/6
8/18
4/9 cup of flour per serving
If we triple the recipe (6 * 3 = 18), we will have a total of 18 servings. Multiply the amount of flour we got for one serving to 18 servings.
4/9 * 18/1
72/9
8 cups of flour for 18 servings

1.) A pipe bursts in your house and you call 2 plumbers for estimates. Plumber A says he
charges $40 to check the problem and $ 55 an hour to repair. Plumber B says he
charges $ 60 to check the problem and $ 40 an hour. If the repair takes 4 hours to
complete, which plumber would be a better option.
Answer: Plumber B
Step-by-step explanation:
Plumber A: First, multiply $55 times 4, then add the fee of $40. This will give you $260 as total. This is how much it would cost for Plumber A.
Plumber B: Multiply $40 by 4 and then add $60. This gives you $220, showing that Plumber B is a better option.
Answer:
Plumber B
Step-by-step explanation:
We could set up 2 expressions, and set the time to be 4 hours, and see which plumber costs less:
Plumber A: 40+55*4 = $260
Plumber B: 60+40*4 = $220
Plumber B is cheaper, so therefore he/she is the better option.
To eliminate 6X you would Transform 2x by multiplying what number ?
Answer:
-3
Step-by-step explanation:
to eliminate 6x we need the same no. 6x but that should be negative. so
