Answer:
4.25
Step-by-step explanation: 12q - 9 ) + ( 8q + 14 ) = 90
Combine like Terms: 20q + 5 = 90
Subtract 5 from both sides: 20q = 85
Divide both sides by 20: q=4*(1/4)
So your angle is 4(1/4) or 4.25 degrees
The general equation for exponential growth can be written as:

where r is the growth rate.
Plugging in the given values, we get:

Therefore

giving
![1+r= \sqrt[3]{1.1} =1.0323](https://tex.z-dn.net/?f=1%2Br%3D%20%5Csqrt%5B3%5D%7B1.1%7D%20%3D1.0323)
The predicted number of bacteria after 17 hours is given by:
Randy made 64 ballon animals and her sister made 32 ballon animals
<em><u>Solution:</u></em>
Let the number of ballon animals sold by Randi be "x"
Let the number of ballon animals sold by her sister be "y"
Cost of 1 ballon animal = $ 0.50
<em><u>Rando made twice as many animals as her sister</u></em>
Number of ballon animals sold by Randi = twice the number of ballon animals sold by her sister
x = 2y ---- eqn 1
<em><u>Together, they earned $ 48</u></em>
Therefore, we can frame a equation as:
Number of ballon animals sold by Randi x Cost of 1 ballon animal + number of ballon animals sold by her sister x Cost of 1 ballon animal = 48


<em><u>Therefore, from eqn 1</u></em>
x = 2y
x = 2(32)
x = 64
Thus Randy made 64 ballon animals and her sister made 32 ballon animals
Multiply 4(-5) then add 6 and theres your X
Answer:
B.
Step-by-step explanation:
Parentheses mean multiplication in this case. So it would be 2 x -3 OR -3 + -3. When multiplying a negative and a positive the answer will ALWAYS be negative. So you would move to the left on a number line.
