can somebody help.................

Answer:

● First part = 2×x = 2x

● Second part= 8×x = 8x

● Third part= 6×x = 6x

Now,

2x+8x+6x = 144

or, 16x= 144

or, x=144/6

or, x=9

therefore, x=9

Answer:

y=3x+5

Step-by-step explanation:

Given:

The selling price of a ratio set = 72.00

Profit percent = 8%

To find:

The cost price for the radio set.

Solution:

Let x be the cost price for the radio set.

Radio set is sold at 8% profit.

[tex]\text{Selling price}=x+\dfrac{8}{100}x[/tex]

[tex]\text{Selling price}=x+0.08x[/tex]

[tex]\text{Selling price}=1.08x[/tex]

The selling price of a ratio set is 72.00.

[tex]72=1.08x[/tex]

[tex]\dfrac{72}{1.08}=x[/tex]

[tex]x=66.666...[/tex]

[tex]x\approx 67[/tex]

Therefore, the cost price for the radio set is 67.

Answer:

u = 66

v = 38

Step-by-step explanation:

In a parallelogram, opposite angles are equal.  U is opposite to 66, so it is 66 degrees

In a parallelogram, corresponding angles are supplementary.  180 - 66 = 114

this means that 3v = 114.  114/3 = 38, which is what v is.

−5.6<−4.2, and −5.6 is located to the left of −4.2

Step-by-step explanation:

Given the statements :

−5.6<−4.2, and −5.6 is located to the left of −4.2 (True) because - 5.6 located to the left of the number line and numbers are arranged from right to left in decreasing order.

−5.6<−4.2, and −5.6 is located to the right of −4.2. (Not true) only the first assertion is correct, - 5.6 < - 4.2, but 5.6 isn't located to the right of - 4.2

−5.6>−4.2, and −5.6 is located to the left of −4.2 (Not true) ; Though 5.6 is located to the left of 4 2, 5.6 is < 4.2

−5.6>−4.2, and −5.6 is located to the right of −4.2. (Not true) ; - 5.6 is < -4.2 and also located to the left of - 4.2

Answer:

4b - a = 15

Step-by-step explanation:

if you replace the variables with their equivalent counterparts you get the equation 4(7) - 12 = __ when you do the math make sure to do the parentheses first then subtract, just like in elementary school remember pemdas parentheses, exponents, multiplication, division, addition, subtraction. I hope this helps.

good luck:)

Actually Welcome to the Concept of the Triangles.

Since there is a linear pair with 40° , the another angle will be 140° ,

also the triangle newly formed is a isosceles one,

hence x = 20°

===> x = 20°

Now apply angle sum property of a triangle on, the other one,

we get as, 70+40+y=180

hence, y = 180-110

y = 70°

Hence angle y ==> 70°

Step-by-step explanation:

Answer:

d = 4.90

Step-by-step explanation:

Given the following data;

F = 9

d = 4

For an inversely proportional relationship, we have;

F = k/d²

Now, we would find the constant, k;

9 = k/4²

k = 9*16

k = 144

Next, to find d, when F = 6

d² = k/F

d² = 144/6

d² = 24

Taking the square root of both sides, we have;

d = 4.90

Answer:

120

Step-by-step explanation:

The formula for a triangle is 1/2bh

so u first multiply 12 by 20 which you will get 240.

After you get 240 u multiply it by the 1/2 which also means dividing by 2.

240 divided by 2 is 120.

Answer:41.8

Step-by-step explanation:

Answer:

62

Step-by-step explanation:

119 is adjacent to angle x. angle x and 119=180 (because the angle of a straight line is 180.) which means to find angle x you have to subtract 119 from 180. 180-119=61. because you now know two angles in the triangle you can add the together and subtract them from 180 (remember 180 is what all the angles in a triangle should add up to 180). 61+57=118 and 180-118=62

Answer:

Step-by-step explanation:

1) 5a - 2b² + 1

Degree of the polynomial = 2

2) 4x²-3x³ + 2x + 12

-3x³ + 4x² + 2x + 12

Degree of the polynomial = 3

To find the degree of the polynomial, arrange it in descending as per the power of the variables.

The highest power of the variable is the degree of the polynomial.

angle DCF = angle DCE + angle ECF

angle DCF = 75° + 54°

angle DCF = 129°

Measure of < DCF is  [tex]129^{0}[/tex].

A figure which is formed by two rays or lines that shares a common endpoint is called an angle.

According to the figure

< DCE = [tex]75^{0}[/tex]

< ECF = [tex]54^{0}[/tex]

Measure of < DCF = < DCE + < ECF

=  [tex]75^{0}[/tex] +  [tex]54^{0}[/tex]

= [tex]129^{0}[/tex]

Hence, measure of < DCF is  [tex]129^{0}[/tex].

Answer:

292.5

Step-by-step explanation:

t= hours, they traveled 4 1/2 hours, or 4.5 hours, so t= 4.5

The expression is 65t, so putting in the 4.5, its

65(4.5), 65 x 4.5= 292.5

So, the answer is 292.5
