Solve this equation: y-3x+15=10

Mathematics
1 answer:
Jlenok [28]3 years ago
3 0

Answer:

10=10

Step-by-step explanation:

y-3x+15=10

y=3x-15+10

y=3x-5

subtitute y=3x-5 in the above equation:

3x-5-3x+15=10 (3x will be eliminated with -3x)

-5+15=10

10=10

(i hope this is the way you want the answer but at least I think it is correct)

I need to calculate X<br><br> 2^x=200<br><br> Solve for x
antoniya [11.8K]
Remember
log(a^z)=zlog(a)
so

notice that 200=2*2*2*5*5, so x cannot be a whole number

take the log base 10 of both sides

log_{10}(2^x)=log{10}(200)
xlog_{10}(2)=log{10}(200)
divide both sides by log_{10}(2)
x= \frac{log_{10}(200)}{log_{10}(2)}

if we used log_{2} instead of log_{10} we would get
x= log_{2}(200) because log_{a}(a^b)=b

What is the volume of a sphere with a diameter of 5.4 ft, rounded to the nearest tenth of a cubic foot?
Lelechka [254]

Answer:

82.4 ft^3

Step-by-step explanation:

Diameter=5.4ft

Radius=diameter/2

=5.4ft/2

=2.7ft

π=3.14

Volume of a sphere=4/3πr^3

=4/3×3.14×2.7^3

=4/3×3.14×19.683

=4/3×61.80462

=247.21848/3

=82.40616

Approximately

82.4 ft^3

An increase in which of the following causes GDP to decrease?
Svetradugi [14.3K]

Answer:

B

Step-by-step explanation:

The GDP measures the market value of all goods and services produced in an economy (country or region) in a specific period of time. The GDP formula is:

GDP= Consumption (C)+ Investment (I)+ Government expenditure (G)+ (Exports - Imports) (Net exports)  

Notice that if exports increase, GDP will increase too. Also, if investment increases GDP will increase. Notice that imports have a negative sign, then if they increase, GDP will decrease.
