Answer:

The value of 2a will be: 16

Step-by-step explanation:

Given the equation

[tex]5 + 6a = 7a-3[/tex]

subtract 5 from both sides

[tex]5+6a-5=7a-3-5[/tex]

[tex]6a=7a-8[/tex]

[tex]-a=-8[/tex]

Divide both sides by -1

[tex]\frac{-a}{-1}=\frac{-8}{-1}[/tex]

[tex]a=8[/tex]

As we know that [tex]a=8[/tex] is the solution to the equation.

Hence, the value of 2a will be:

[tex]2a = 2(8)[/tex]    ∵ [tex]a=8[/tex]

     [tex]= 16[/tex]

Therefore, the value of 2a will be: 16

Answer: 24.24 miles

Step-by-step explanation:

We should note that 1000 metres = 1 kilometer.

Imelda rode her bicycle 39 kilometers which will be converted to meters a:

= 39 × 1000

= 39000 meters

Since 1 meter = 1.094 yards

39000 meters = 39000 × 1.094 = 42666 yards

To find find the distance Imelda rode her bicycle to the nearest mile goes thus:

1 mi = 1760 yd

42666 yards will be converted to miles. This will be: 42666/1760 = 24.24 miles

Answer:

Equation of line passing through origin and (7,2) is: [tex]y = \frac{7}{2}x[/tex]

Step-by-step explanation:

The general form of equation of line is given by:

[tex]y = mx+b[/tex]

When a line passes through origin it has no y-intercept so the equation will become

[tex]y = mx[/tex]

Slope is given by the formula

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Here,

(x1,y1) = (0,0)

(x2,y2) = (7,2)

Putting the values in the formula

[tex]m = \frac{7-0}{2-0} = \frac{7}{2}[/tex]

Putting the value of slope in equation of line

[tex]y = \frac{7}{2}x[/tex]

Hence,

Equation of line passing through origin and (7,2) is: [tex]y = \frac{7}{2}x[/tex]

Answer:

1. x=66

2. x=-3

Step-by-step explanation:

1. x\6-2=9

add 2 to both sides

x\6=11

multiply both sides by 6

x=66

2. -7(3x-4)=91

distribute -7 into parenthesis

-21x+28=91

subtract 28 from both sides

-21x=63

divide both sides by -21

x=-3

Answer:

1: 66 2: -3

Step-by-step explanation:

9+2=11

11=x/6

x=66

-21x+28=91

91-28 = -21x

63=-21x

x = -3

A. 12 pieces of 42.3 centimeter long rope.

= 12 × 42.3

= 507.6

This is wrong

B. 15 pieces of 33.6 centimeter long rope

= 15 × 33.6

= 504cm

This is correct

C. 16 pieces of 31.5 centimeter long rope

= 16 × 31.5

= 504cm

This is correct

D. 20 pieces of 25 centimeter long rope

= 20 × 25

= 500cm

This is incorrect

E. 35 pieces of 14.4 centimeter long rope

= 35 × 14.4

= 504cm

This is correct

Therefore, the correct option are B, C and E.

Answer:

D-159

Step-by-step explanation:

The required measure of angle ABD is 142°. Option B is correct.

Given that,
Triangles ACD and BCD are isosceles. Angle BAC has a measure of 17 degrees and angle BDC has a measure of 52 degrees.

The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not greater than 180°

Here,
According to the question,
ΔBDC,

∠BDC + ∠BCD + ∠DBC = 180
52 + 52 + ∠DBC = 180
∠DBC = 180 - 104
∠DBC = 76°
Now,
∠ABD = 360 - ∠DBC / 2
∠ABD = [360 - 76] / 2
∠ABD = 284/2
∠ABD = 142°

Thus, the required measure of angle ABD is 142°. Option B is correct.

The graph will be Option C. passing through the point y = -2

The equation of line is y = -2 and the graph will be passing through the point y = -2

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Now , the equation of the line is given by

2y + 4 = 0

Subtracting 4 on both sides , we get

2y = -4

Divide by 2 on both sides , we get

y = -2

Therefore , the equation of line is y = -2

So , the line graph will be having a straight line 2 units down on the negative y-axis

Hence , the equation of line is y = -2 and the graph will be passing through the point y = -2

Answer:

y = 2/5x + 1/5

Step-by-step explanation:

y - y1 = m(x - x1)

y - 1 = 2/5(x - (-3))

y - 1 = 2/5(x + 3)

y - 1 = 2/5x + 6/5

y = 2/5x + 6/5 - 5/5 (since 1 equals to 1/1, 2/2, 3/3, etc.)

y = 2/5x + 1/5

Answer:

a = 5√7

Step-by-step explanation:

Sides of a right triangle follow the Pythagoras theorem,

By Pythagoras theorem,

(AB)² = (BC)² + (AC)²

c² = a² + b²

If b = 9 and c = 16,

(16)² = a² + 9²

256 = a² + 81

a² = 256 - 81

a = √175

a = 5√7

Therefore, measure of third side a = 5√7

Complete question is;

In a hydraulic system, a 100-newton force is applied to a small piston with an area of 0.0020 m².

This hydraulic system should produce an output force of 50,000 newtons. How large an area should the output piston have?

Answer:

A2 = 1 m²

Step-by-step explanation:

Using Pascal's Law which is here applied to mechanical advantage of a hydraulic piston, we can find the area of the large piston from;

F1/A1 = F2/A2

We are given;

Force of small piston: F1 = 100 N

Area of small piston; A1 = 0.0020 m²

Force of small piston: F2 = 50000 N

Thus;

Making A2 the subject, we have;

A2 = (F2/F1)A1

A2 = (50000/100) × 0.0020

A2 = 1 m²

The phrase Corresponding Parts of Congruent Triangles are Congruent with the acronym CPCTC, is used as valid reasoning in the provision of a proof, after the existence of congruency between two triangles has been proven

Given that the triangles ΔDOG and ΔCAT have been proven congruent, we have that the corresponding vertices are;

Vertex D corresponds to vertex C

Vertex O corresponds to vertex A

Vertex G corresponds to vertex T

Therefore, given that ΔDOG ≅ ΔCAT, we have;

Answer:

a) Equation is: 3x+4=22

b) Solving the equation we get the number x = 6

Step-by-step explanation:

a) Equation

Let the number be x.

Translating the statement into mathematical form:

Multiply the number with 3 i.e 3x

Add four i.e 3x+4

I get twenty two means: 3x+4=22

So, Equation is: 3x+4=22

b) Solve the equation:

3x+4=22

subtracting 4 on both sides

[tex]3x+4=22\\3x+4-4=22-4\\3x=18[/tex]

Divide both sides by 3

[tex]\frac{3x}{3}=\frac{18}{3}\\x=6[/tex]

So, the number x = 6

We have:

y = 4x - 5

Lets add 5 in each member:

y + 5 = 4x - 5 + 5

y + 5 = 4x

Divide the entire equation by 4:

[tex]\dfrac{y+5}{4} = \dfrac{4x}{4}\\\\\dfrac{y+5}{4} = x\\\\x = \dfrac{y+5}{4}\\\\\boxed{x = \dfrac{y}{4} + \dfrac{5}{4}}[/tex]
