3.2b + 10 = -1.7b - 4.7

Answers

Answer 1

Answer:

b = -3

Step-by-step explanation:

3.2b + 10 = -1.7b - 4.7

add 1.7b to each side

3.2b+1.7b + 10 = -1.7b+1.7b - 4.7

4.9b +10 = -4.7

Subtract 10 from each side

4.9b +10-10 = -4.7-10

4.9b = -14.7

Divide each side by 4.9

4.9/4.9 = -14.7/4.9

b = -3

The slope is 1 or -1 depending on if the line is going down or if it’s going up.

To find the slope count how many units up from the starting point to the end point which is 14. Then divide that number by how many units horizontally from the starting point to the end point which is 14. 14/14=1.
In this case (taking that each block is 1) you can see that the line is y=x +1.

Step-by-step explanation:

Given b =4, h=6,  H=3, let us find the area.

First we find the area of the triangular face.

(b*h)/2 = 4*6/2 = 24/2 = 12

Then we multiply 12 by the height of the cheese

12*H = 12*3= 36

36 <40, therefore she does not have enough.

Find the value of x ​

Answers

X is 38
hope it helped

Answer:

x = 38°

Step-by-step explanation:

this is a four-sided polygon, so the sum of the interior angles measures 360 degrees; formula is (n - 2) · 180 where 'n' is the number of sides

add all four expressions and set equal to 360

5x - 33 + 5x + 13 = 360

10x - 20 = 360

10x = 380

x = 38

check by plugging 38 into each expression to make sure the total is 360

starting in upper left and moving clockwise, the angles are: 75°, 82°, 114°, 89°

m∠V = 90°, m∠U = 60°, m∠W = 30°
m∠V = 30°, m∠U = 90°, m∠W = 60°
m∠V = 60°, m∠U = 90°, m∠W = 30°

Answers

Answer:

m∠V = 60°, m∠U = 90°, m∠W = 30°

Step-by-step explanation:

hope this helps y'all out

The angle measures of triangle VUW are m∠V = 90°, m∠U = 60°, m∠W = 30°

Application of SOH CAH TOA identity

From the given diagram;

Opposite side to <V = 3√3 cmHypotenuse = 6cm

According to the rule:

sin <V = opp/hyp

sin <V = 3√3/6

sin <V = √3/2

<V = 60 degrees

Since the triangle is right-angled, the measure of m<U is 90 degrees

Also, the sum of interior angle of a triangle is 180 degrees, hence;

60 + 90 + <W = 180

<W = 180 - 150

<W =  30 degrees

Hence the angle measures of triangle VUW are m∠V = 90°, m∠U = 60°, m∠W = 30°

Step-by-step explanation:

The expressions are 2+3 and 3−6.

We need to find the value of x such that the expressions 2+3 and 3−6  have same value.

2+3 = 3−6

Taking like terms together,

3+6 = 3x-2x

⇒ x = 9

So, the value of x is 9 such that 2+3 and 3−6  have same value.

Sammie read at the rate of 25 pages per hour. Alex read at the rate of 1/2 of a pages per minute. Who was reading faster? By how many pages per hour faster?

Answers

Answer:

Alex and 5 pages

Step-by-step explanation:

Sammie 25 pages per hour

Alex 1/2 pages per minute

You do 1/2x60=30 because you can find out how many pages he can read per hour.  Which is 30 pages per hour.  So Alex can read 30 pages per hour and Sammie can only read 25 pages per hour.  To find how many pages he reads faster per hour, you have to take 30 and subtract it by 25 to get 5 extra pages.  So Alex reads 5 pages faster per hour.  In the end, Alex reads faster than Sammie by 5 more pages per hour.
