4(b + 5) = 3b + 35. what is b​

Answer:

1. 7 1/4

2. 3 1/4

3. 2 2/3

4. 2 1/2

Step-by-step explanation:

1. You subtract 8-3/4=7 1/4

2. You have to add 2 3/4 hour + 1/2 an hour = 3 1/4 hours

3. You take 3 2/6 - 2/3= to make it easier you want to change the fractions so there the same denominator 2/6->1/3 now it will be much easier to subtract 3 1/3-2/3= 2 2/3

4. Finally you do 8-5 1/2 =2 1/2

I hope this helps if not you can comment and I'll try and further explain

Answer:

[tex]V=V_{1}+V_{2}=96+36=132\: cm^{3}[/tex]

Step-by-step explanation:

We can divide it into two parts:

First, we can fin the volume of the parallelepiped:

h1 = 16 cm

w1 = 2 cm

d1 = 3 cm

[tex]V_{1}=h_{1}*w_{1}*d_{1}=16*2*3=96\: cm^{3}[/tex]

Now, the volume of the second parallelepiped is:

h2 = (8-2) cm = 6 cm

w2 = 2 cm

d2 = 3 cm

[tex]V_{2}=h_{2}*w_{2}*d_{2}=6*2*3=36\: cm^{3}[/tex]

Finally, the total volume will be the addition of these two volumes.

[tex]V=V_{1}+V_{2}=96+36=132\: cm^{3}[/tex]

I hope it helps you!

Answer:

(2,4)

Step-by-step explanation:

the point where the lines intercept is the solution, so it is (2,4)

Answer:

(2,4)

Step-by-step explanation:

Look where the points are intersecting; if you have a graph representing a system of equations, it is always easy to find their solution.

Here the lines are intersecting at (2,4)

Answer:

x+y=68

x-y=15

Step-by-step explanation:

A "sum" means that we will be using addition, while a "difference" indicates subtraction. Anytime we have two unknown numbers we generally use "x" and "y".

Answer:

dimensions of the book are 2 in. by 24 in.    

Step-by-step explanation:

I assume the book is a rectangle

Let w = the width

     l = the length

A = lw = 48         P = 2w + 2l = 52

                                   w + l = 26

                                          l = 26 - w

w(26-w) =48

26w - [tex]w^{2}[/tex] = 48

[tex]w^{2} - 26 w + 48 = 0[/tex]

(w-2)(w -24) =  0

w = 2    or   w = 24

                           if w = 2, then l = 26 - 2 = 24

                           if w = 24, then l = 26 - 24 = 2

So, the dimensions of the book are 2 in. by 24 in.    

Answer:

The two numbers are 18, and 81.

step-by-step explanation:

If you divide both sides of the ratio by 2 to get 4.5/1, you can then graph that as y=4.5x, finally you just find two numbers that have a difference of 63, which in this case is 18, and 81.

18 + 14 = 32.

Answer:

The answer is 9

Step-by-step explanation:

Multiplying by 1/72 is the same as dividing by 72. When you multiply 648 by 1/72, think of it as multiplying

[tex]\frac{648}{1}[/tex] x [tex]\frac{1}{72}[/tex] which equals...[tex]\frac{648}{72}[/tex]. If you have a calculator, at that point, you can just divide 648 by 72. If not, you can use standard division.

Hope this helps!

Answer:

∠x = 72°

Step-by-step explanation:

since two sides are equal, their opposite angles are equal.

Then the upper angle is also equal to 54°.

All triangle angles add up to 180°.

∠x = 180 - 54 - 54 = 72°

Answer:

6 23/24

Step-by-step explanation:

First, find the least common factor of 8 and 12, the denominators.

8 16 24

12 24

24, is now the current denominnator,

8x 3 = 24

Now you go do it to the numerator, 3 x 3 = 9

9/24 + ?

Now, 12 x 2 = 24, do it to the numerator, 7 x 2 = 14

4 9/24 + 2 14/24

Now add the front numbers to make 6, than add the numerators and keep the denominator.

6 23/24, since you can not simplify this fraction, this is the answer.

Answer:

Step-by-step explanation:

Yes 6 over 9 simplifys to 2 over 3.

And 4 over 6 simplifys down to 2 over 3

Answer:

(-5, 3)

Step-by-step explanation:

Let O(x, y) be the centroid of the triangle.

The median of a triangle is a line segment that joins the vertex of a triangle to the midpoint of the opposite side. There are three medians in a triangle; and the medians of a triangle intersect at a point called the centroid.

The centroid of a triangle is gotten from the average of the x coordinates and the y coordinates of all the three vertices.

For Triangle ABC has vertices A (3,-3) B (-7,9) C (-11,3) and centroid O(x, y). Hence:

[tex]x=\frac{3 + (-7)+(-11)}{3}=-5\\\\y=\frac{-3 + 9 + 3}{3} =3[/tex]

The centroid is at (-5, 3)
