Answer:
23/20 or 1 and 3/20
Step-by-step explanation:
Make sure they have the same common denominator. For 5 and 4, 20 would be the Least Common Denominator.
so 2/5=8/20 and 3/4=15/20
Add 8+15 and you get 23 so 23/20 you can leave it so or switch it to a mixed number 1 3/20
the given expression is,
so the factors are (3v - 7) (v + 1)
the given equation is,
so the answer is
(3v-7)(v+1)
Answer:
![x=5\sqrt[3]{3}](https://tex.z-dn.net/?f=x%3D5%5Csqrt%5B3%5D%7B3%7D)
or 7.21
Step-by-step explanation:
x³ = 375
You have to take the square root and have the index 3:
You have to have the index 3 because x is cubed and you have to get rid of the cubed sign since a normal square root is for when the exponent is 2:
![\sqrt[3]{x^3} =\sqrt[3]{375} \\x=5\sqrt[3]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E3%7D%20%3D%5Csqrt%5B3%5D%7B375%7D%20%5C%5Cx%3D5%5Csqrt%5B3%5D%7B3%7D)
In decimal form (rounded to hundredths):
7.21
Your work shows you did this correctly!
Answer:
B. 39
Step-by-step explanation:
134 is a supplementary angle, so 180-134=46. 46 is the bottom left interior angle of the triangle.
Next that 56 and the bottom right exterior angle are supplementary, so 180-56=124.
now we have the bottom right exterior angle, to find the interior 180-124=56.
Then we can set up the equation to find x:
56+46+2x=180
we have 180 because all triangles angle equal 180.
calculate the equation:
combine like terms, (2x)+(56+46)=180
2x+102=180
Subtract 102 from both sides,
180−102=78
2x=78
Divide both sides by 2.
78/2=39
x=39.
