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

Hopes Helps
I need help I’m stuck on this question.
Answer:
No
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.
I hope this helps! :)

Find the value of x
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°

What are the angle measures of triangle VUW?
m∠V = 30°, m∠U = 60°, m∠W = 90°
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°
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 identityFrom the given diagram;
Opposite side to <V = 3√3 cmHypotenuse = 6cmAccording 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°

For what value of do the expressions 2+3 and 3−6 have the same value?
[tex]x[/tex] =
Answer:
x = 9
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?
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.
Hope this helps! Please give brainliest.

x = 12
Step-by-step explanation:
By the alternite intereor angle therom, the two expresions equel each other
8x - 15 = 3x + 45
8x -3x - 15 = 3x - 3x + 45
5x - 15 = 45
5x - 15 + 15 = 45 + 15
5x = 60
5x/5 = 60/5
x = 12
Answer:
8x-15=3x+45 alternate angle
8x-3x=45+15
5x=60
x=60/5=12
