Answer:
C > 17
Step-by-step explanation:
23 - C < 6
-23 -23
-----------------
-C < -17
multiply both sides by -1
(-c) (-1) > (-17) (-1)
C > 17

Are 10 - 20 and 5(2 - 20) equivalent expressions? Explain.
Answer:
No.
Step-by-step explanation:
Take the second expression: 5(2 - 20)
To solve, you must distribute the 5 to all terms within the parenthesis:
5(2 - 20) = (5 * 2) - (5 * 20) = 10 - 100 = -90
On the other hand:
10 - 20 = -10
∴ the two expressions are not equivalent.

1. Trish can complete 10 problems in 60 minutes. At this rate, could she complete 25 problems in 130 minutes? Write your answer as YES or
NO.
Please explain. I think it’s a two step equation.
Answer:
[tex] k = \dfrac{5}{3} [/tex]
Step-by-step explanation:
It is actually a one-step equation.
If you have a number multiplying a variable equaling another number, then you need to do only one operation to solve; you need to multiply both sides by the reciprocal of the number multiplying the variable.
Here we have
[tex] \dfrac{3}{2} = \dfrac{9}{10}k [/tex]
First, switch sides to have the variable, k, on the left side.
[tex] \dfrac{9}{10}k = \dfrac{3}{2} [/tex]
You have a variable, k, multiplied by a number, the fraction 9/10, equaling another number, 3/2. To solve for k, multiply both sides by the reciprocal of 9/10 which is 10/9.
[tex] \dfrac{10}{9} \times \dfrac{9}{10}k = \dfrac{10}{9} \times \dfrac{3}{2} [/tex]
On the left side, you have the product of two reciprocals, 10/9 and 9/10, which equals 1, leaving just k.
On the right side, you must multiply the fraction 10/9 by 3/2 and then reduce.
[tex] k = \dfrac{30}{18} [/tex]
[tex] k = \dfrac{5}{3} [/tex]

f(x)= -2x^2 - 5 and f(2)= -13
can someone solve this in steps please?
This is one way you could write out the steps
f(x) = -2x^2 - 5
f(2) = -2(2)^2 - 5
f(2) = -2(4) - 5
f(2) = -8 - 5
f(2) = -13
Answer:
Step-by-step explanation:
First you have to get the meaning clear.
f(2) means that wherever you see an x on the right side of the equation, you put a 2.
f(2) means -2*(-2)^2 - 5
(-2)^2 = -2 * -2 = 4
f(2) = -2 * 4 - 5
f(2) = - 8 - 5
f(2) = -13
If grapes are 92% water and raisins are 20% water by weight, then how much did a quantity of raisins, which currently weighs 10 pounds, weigh when all the raisins were grapes
10 lbs of raisins contains 20% water by weight, so they contain
0.20 × (10 lbs) = 2 lbs
of water. This means the non-water portion of the raisins weighs 8 lbs. This weight stays the same throughout the drying process.
As grapes, they had a total weight of
8 lbs + w
where w is the water weight, and w happens to be 92% of this total weight. So
w = 0.92 × (8 + w)
Solve for w :
w = 7.36 + 0.92w
0.08w = 7.36
w = 92
Then the total weight of the grapes before they dried out is 100 lbs.

Write an equation for the situation then solve for x.
Julio rented a bike from Krystal's Bikes. It
cost $13 plus $2 per hour. If Julio paid $17,
then he rented the bike for how many hours?
The number of hours should be 2.
Given that,
There is the cost of $13 plus there is $2 per hour.And, the amount paid is $17.Here we assume the number of hours be x.Based on the above information, the equation is as follows:
2x + 13 = 17
2x = 17 - 13
2x = 4
x = 2
Therefore we can conclude that the number of hours should be 2.

The at {x} = 10, the value of the function remains +8.
What is function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is that the function f(x) is defined as -
f(x) = + 8
The given function is a constant function. This means that the value of the function remains the same irrespective of the value of {x} or the value in the function domain. So, at {x} = 10, the value of the function remains +8 only. This is true for all the values of {x}.
Therefore, the at {x} = 10, the value of the function remains +8.
