Twice means two times something so2a. Four more than means adding for so your answer is 2a+4
Answer:
(A)the temperature of 76.1 degrees Fahrenheit converted to degrees Celsius
Step-by-step explanation:
Kareem plans to use the function 
to convert temperature from degrees Fahrenheit to degrees Celsius.
The function gives a result in degrees Celsius. Therefore, 76.1 is in degree Fahrenheit and the result C(76.1) will be in degree Celsius.
Therefore, C(76.1) represents the temperature of 76.1 degrees Fahrenheit converted to degrees Celsius.
The correct option is A.
Well when you simplify it you get this,
0=-24,
Do what’s inside the parentheses first
3-3 is 0, 3•0 is 0
2•positive 3 is 6
6- -30 is -24
So you have 0=-24
Or just -24 :)
S=4π<span>r<span>2 - this is the equation for the surface area of a sphere. We know that the radius (r) is 3.5 so here's how to solve this:
S = 4</span></span><span>π r2
S = 4</span><span>π (3.5)2
S = 4</span><span>π 12.25
S = 49</span><span>π
The surface area of a sphere with radius of 3.5 is 49</span><span>π.</span>
Answer:
These are simultaneous equations.They have to be solved like this:
2x-y=3 -y=3-2x 2x-3= -x
y= -x y= -(3-2x) 3x= 3
y=2x-3 x=1
Step-by-step explanation:
The value of x equals to 1
