Answer:

Step-by-step explanation

what I learned was to separate the two shapes.

So the rectangle and the triangle will be multiplied separately.

We will make the 10 an 8 because of the 2 on top of the rectangle.

5*8= 40 because the shape is a triangle we divide the area of it by 2, and that would make 20. The triangles area is 20.

Now the rectangle: 2*3=6    

Add both of those numbers and the answer is 26 ft.

Answer: he bought 1 and 1/2 pounds of meat. (also could be written as 1.5 pounds)

Step-by-step explanation:

We know that Tim bought all of the two 3/4 lb packages for a party.

Then he bought 2 packages. Such that each package has  3/4 lb meat.

Then the total amount of meat that Tim has is equal to 2 times the amount of meat in each package, this is:

Total meat = 2*(3/4 lb) = (6/4 lb)

and we can write 6 = 4 + 2

then:

Total meat =  6/4  lb = (4 + 2)/4  lb = (4/4 + 2/4) lb = (1 + 1/2) lb

So he bought 1 and 1/2 pounds of meat. (also could be written as 1.5 pounds)

Answer:

B. 29º

Step-by-step explanation:

Given that BCDE is a parallelogram, then [tex]BE \parallel CD[/tex] and A, E and D are collinear. Then, angle E inside triangle ABE and angle D inside parallelogram BCDE have the same measure. That is:

[tex]\angle D = \angle E = 51^{\circ}[/tex] (1)

In addition, the sum of internal angles in triangles equals 180º, which implies that:

[tex]\angle A + \angle B + \angle E = 180^{\circ}[/tex] (2)

If we know that  [tex]\angle B = 100^{\circ}[/tex] and [tex]\angle E = 51^{\circ}[/tex], then [tex]\angle A[/tex] is:

[tex]\angle A = 180^{\circ}-\angle B - \angle E[/tex]

[tex]\angle A = 180^{\circ}-100^{\circ}-51^{\circ}[/tex]

[tex]\angle A = 29^{\circ}[/tex]

Hence, correct answer is B.

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°

We need to prove angle sum property.

What is angle sum property?

The sum of interior angles of a triangle is 180 degrees

Consider a ∆ABC, as shown in the figure below. To prove the above property of triangles, draw a line PQ parallel to the side BC of the given triangle

Since PQ is a straight line, it can be concluded that:

∠PAB + ∠BAC + ∠QAC = 180°  ………(1)

Since PQ||BC and AB, AC are transversals,

Therefore, ∠QAC = ∠ACB (a pair of alternate angle)

Also, ∠PAB = ∠CBA (a pair of alternate angle)

Substituting the value of ∠QAC and ∠PAB in equation (1),

∠ACB + ∠BAC + ∠CBA= 180°

Thus, the sum of the interior angles of a triangle is 180°.

Answer:

Step-by-step explanation:

Point (-1, 4) it's point where x-coordinate is -1 and y-coordinate is 4

Graph in B is the only one passing through (-1, 4)

The equation of the line is y = 2x + 6. The graph is represented by B.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that the slope of the line is 2 and the point through which it is passing is (-1,4).

The equation of the line will be calculated as,

y = mx + c

y = 2x + c

4 = -2 + c

c = 6

The equation will be written as,

y =2x + 6

The graph of the line is attached with the answer below.

Answer:

x=1

Step-by-step explanation:

you would change it to 5x-4(-3x+5)=-3, because you put the info for the first equation into the second equation.

5x-4(-3x+5)=-3

5x+12x-20=-3

17x-20=-3

17x=17

x=1

Answer:

(1,2)

Step-by-step explanation:

1) To solve using substitution, first isolate one of the variables in one of the equations. However, the y in y = -3x + 5 has already been isolated, so we don't need this step. Instead, take that value of y and substitute it for the y in the other equation, 5x - 4y = -3. So, substitute -3x + 5 for the y in 5x - 4y = -3 and solve:

[tex]5x-4(-3x+5)= -3\\5x+12x-20=-3\\17x-20=-3\\17x = 17\\x = 1[/tex]

2) So, x = 1. Now, take that value of x and substitute back into any of the equations to find the y value. (I chose to substitute it into y = -3x + 5, but either choice is fine). So, substitute 1 for the x in y = -3x + 5 and solve:

[tex]y = -3(1)+5\\y = -3+5\\y = 2[/tex]

So, y = 2. Thus, by knowing both x and y values, the solution would be (1,2).

Step-by-step explanation:

The equation T = 4v + 3 is solved for v will be written as v = (T - 3) / 4.

The possible value of the variables that satisfy the equation which is known as the solution of the equation.

The equation is written below.

T = 4v + 3

The degree of the equation is one. Then the equation is given a linear equation.

Solve the equation for v, then we have

T = 4v + 3

Subtract 3 from both sides, then we have

T - 3 = 4v

Divide the equation by 4 into both sides, then we have

v = (T - 3) / 4

The equation T = 4v + 3 is solved for v will be written as v = (T - 3) / 4.
