4x – 5 + 2(x – 3) = 12x + 7
X=
Answer:
-3
Step-by-step explanation:
4x - 5 + 2(x - 3) = 12x + 7
4x - 5 + 2x - 6 = 12x + 7
4x + 2x - 5 - 6 = 12x + 7
6x - 11 = 12x + 7
collect like terms
6x - 12x = 7 + 11
-6x = 18
-x = 3
x = -3

Find the surface area of a sphere with radius 5 using the formula SA=4pir2
Leave answer in terms of n
A. 75 pi units squared
B. 100 pi units squared
Answer:
B. 100 pi units squared
Step-by-step explanation:
Find the surface area of a sphere with radius 5 using the formula SA=4pir²
Leave answer in terms of π = pi
From the question
The formula for the Surface Area if a square = 4 × pi × r²
r = 5
Hence,
Surface Area of a Sphere = 4 × pi × 5²
= 100 pi units squared
Option B is the correct option

what is the slope of the line?
Answer:
y = 2x - 3
Step-by-step explanation:
Since the line is going 2 down and 1 left. The slope is 2.
The line crosses the y-intercept at -3.
y = 2x - 3
Answer:
m = 2
Step-by-step explanation:
You have to use the slope formula and insert your points into the formula. Your formula should have turned into 0 - (-3)/1.5 - 0. If you simplfy your equation your get m(slope)=2.
Hope this helps! :D

Phoebe has 72 roses that she is putting into 5 vases. If she puts the same number of roses in each vase, how many roses are left over?
Answer:
2 roses left over
Step-by-step explanation:
72/ 5 = 14.4
so we know for sure that we can put 14 roses on each vase but no mor than 14 on each vase Some will be left left over
14x5 = 70
72-70 = 2 (2 roses left over)

What is length of BW using what you know? DONT GIVE ME A LINK JUST ANSWE PLEASEE (will give brainlist)
Answer:
The length of BW is [tex]105\sqrt{2}[/tex], or about 148.49.
Step-by-step explanation:
For this problem, we will assume that the figure is a square. We will call the figure "Figure BOWL".
Because figure BOWL is a square, we know that the lengths of each sides of the square are equal, so the length of each side is 105.
Notice that the BW, OB, and WO make a triangle. We'll call it triangle BOW. Since figure BOWL is a square, we know that angle BOW is 90°, and so triangle BOW is a right triangle.
Since triangle BOW is a right triangle, we can solve for BW using the Pythagorean theorem, [tex]a^{2} + b^2 = c^2[/tex]. "a" and "b" are the legs of the triangle, while "c" is the hypotenuse of the triangle.
In triangle BOW, the legs are OB and WO, while the hypotenuse is BW.
Plug in the values for the equation and solve.
[tex]a^2 + b^2 = c^2[/tex]
[tex]OB^2 + WO^2 = BW^2[/tex]
[tex]105^2 + 105^2 = BW^2[/tex]
[tex]11,025 + 11,025 = BW^2[/tex]
[tex]22,050 = BW^2[/tex]
[tex]\sqrt{22,050} = BW[/tex]
We can either use the estimated value, or the exact simplified value of [tex]\sqrt{22,050}[/tex].
Here is the exact simplified value:
[tex]\sqrt{22,050} = \sqrt{25 * 882} = \sqrt{25 * 9 * 98} = \sqrt{25 * 9 * 49 * 2} = \sqrt{5^2 * 3^2 * 7^2 * 2} = (5 * 3 * 7)\sqrt{2} = 105\sqrt{2}[/tex]
BW = [tex]105\sqrt{2}[/tex]
For the estimated value, just use a calculator:
[tex]\sqrt{22,050}[/tex] ≈ 148.49
BW ≈ 148.49

The model below has an area of 16 square units which expression represents the side length of the model in units /64 /4 /16 /8
Answer:
4
Step-by-step explanation:
the area of a square = length²
16 = length²
find the square root of both sides of the equation
length = 4
How do you solve this proof?
Answer:
1) Given
2) Isosceles triangle's 2 sides are equal. Vertex angle is M. So, ML = MN

7). 1/(√7-√11)
= 1×(√7+√11)/(√7-√11)(√7+√11)
= √7+√11 / (√7)² - (√11)²
= √7 + √11 / 7 - 11
= √7 + √11 / (-4)
EXPLAINATION:
to rationalize the denominator we multiply the numerator and the denominator by the denominator, but with the opposite sign.
For example - in the first question we multiplied 1 and √7 - √11 by √7 + √11 .
What fraction of the square is the green triangle?
Answer:
1/4
Step-by-step explanation:
Answer:
7/32
(btw thats the simplified version....look at the bottom for non-simplified if you didnt need it simplified)
Step-by-step explanation:
first count how many squares there are in total
its 8 by 8 so in total there are 64!
now there is the green triangle.....
count all the whole squares in it = 10
now count all the half squares (little triangles in it)= 8
Now if you put those little triangles together it would make one small unit square so it is 4 of all
10 + 4 = 14
So there is a Total of 14 unit squares in the green triangle
Fraction Time......
now lets take 14/64 and simplify it
that would be 7/32
We cant make it any more simplified now if you werent looking for the simplified version the your answser would be 14/64
I hope this was the answser you were looking for!! Mark Me Brainliest ;)A bag contains 4 white, 3 blue, and 3 red marbles. Find the probability of choosing a red marble, then a white marble if the marbles are not replaced
