Answer: b=4

Step-by-step explanation: 4b+5=1+5b = B = 4

Answer:

b = 4

Step-by-step explanation:

subtract 4b from 5b and you get 1b. subtract 1 from 5 and u get 4 = 1b. divide both sides by 1 therefore b = 4

Answer:

3x+5y+22

Step-by-step explanation:

Answer:

3x + 5y + 22

Step-by-step explanation:

Given expression:- x + 3y + 2x + 10 + 2y + 12

Here, you can add all the 'x' terms together and 'y' terms together.

There is an 'x' and '2x'.

On adding them, you get 2x + x equals 3x.

Then add the 'y' terms

There is a '3y' and a '2y'. On adding them, you get 3y + 2y equals 5y.

Then add the numbers that are left. 12 and 10.

12 + 10 equals 22.

Then take all the values we got after addition:- 3x, 5y and 22.

2x, 5y and 22 cannot be added together. So, the expression in the simplified form would be:-

Answer:

X = 13

X = 70

Step-by-step explanation:

1. Since it is a right angle set the equation up as X +2 + 75 = 90.

X =13

2. Set up x - 20 + 40 = 90 since right triangles are 90 degrees

x = 70

Are we supposed to answer something?

Also Woww! :00

Answer: 5 times

Step-by-step explanation:

Let the number of times that he saved $75 be x.

Let the number of times that he saved $150 be y.

Therefore, based on the information given in the question, we can form an equation which will be:

x + y = 8 ...... i

75x + 150y = 825 ....... ii

From equation I,

x + y = 8

y = 8 - x....... iiii

Put equation iii into ii and this will be:

75x + 150y = 825

75x + 150(8 - x) = 825

75x + 1200 - 150x = 825

75x - 150x = 825 - 1200

-75x = -375

x = 375/75

x = 5

He saved $75 5times from his paycheck.

Answer:

(9+13)/2*10

=22/2*10

=11*10

=110

Step-by-step explanation:

First, we figure out the formula for areas of trapezoids is (a+b)/2*h.

Next, we plug in the numbers which will give use the equation:

22/2*10

Lastly, we solve:

11*10=110

Answer:

800 × 7 + 60 × 7 + 2 × 7

Step-by-step explanation:

The area of the figure equals :

Area of rectangle = Length * width

Width = 7

Length = 862

862 in expanded form:

800 + 60 + 2

Hence, Multiplying the expanded form by the width ;

(800 + 60 + 2) * 7

800*7 + 60*7 + 2*7

Answer:

106.25

Step-by-step explanation:

125x.15 (15% discount)=18.75 discount

125-18.75=106.25

The answer will be 100.48

If we take π = 3.14.

hope this helps you out :)

Answer:

(First of all its 20 points not 40 but any ways) A ferris wheel has a raidus of 20 m. Passengers get on halfway up on the right side. The direction of rotation is counter clockwise. The bottom of the ferris wheel is 2 m above ground. It rotates every 36 seconds. Determine height above the ground after 15 seconds algebraically. Determine seconds to the nearest tenth when height is 38 m above the ground algebraically.

**

let t=seconds after wheel starts to rotate.

let h=meters above ground after wheel starts to rotate

..

The formula I got: h(t)=20sin(πt/18)+22

This is close to the formula you got, except I left the negative sign out since passengers start to rise after the wheel starts going counter-clockwise.

..

After 15 seconds:

h=20sin(15π/18)+22

=20sin(5π/6)+22

=20*(1/2)+22

=32 m

..

When h=38 m

38=20sin(πt/18)+22

38-22=20sin(πt/18)

20sin(πt/18)=16

sin(πt/18)=16/20=4/5=.8

arcsin(.8)=0.927

πt/18=0.927 (radians)

t=(.927*18)/π≈5.31

..

height above the ground after 15 seconds≈38 m

seconds elapsed when height is 38 m above ground≈5.3 seconds
