The value of x for which equation 0.75(x + 20) = 2 + 0.5(x - 2) becomes true is equal to -56.
An equation is given which is 0.75(x + 20) = 2 + 0.5(x - 2).
We have to find out the value of x for which the equation becomes true.
What do you mean by algebraic expressions ?
The algebraic expressions are those which are made up of variables, constants and algebraic operations i.e., addition, subtraction, etc.
As per the question ;
The equation given is 0.75(x + 20) = 2 + 0.5(x - 2)
Let's solve to get the value of x.
⇒ 0.75(x + 20) = 2 + 0.5(x - 2)
⇒ 0.75x + 15 = 2 + 0.5 x - 1
⇒ 0.75x - 0.5x = 1 - 15
⇒ 0.25x = - 14
⇒ x = -14 ÷ 0.25
⇒ x = - 56
Let's check ;
0.75(x + 20) = 2 + 0.5(x - 2)
0.75 ( -56 + 20 ) = 2 + 0.5 ( -56 - 2 )
(0.75 × -56) + (0.75 × 20) = 2 + (0.5 × -56) + (0.5 × -2)
-42 + 15 = 2 -28 - 1
-27 = -27
Both sides are equal for value of x = -56.
Thus , the value of x for which equation 0.75(x + 20) = 2 + 0.5(x - 2) becomes true is equal to -56.

Shelley wants to purchase a cell phone package, which includes a free phone. The cost of the package is $0.10 per minute, for the number of minutes she uses the phone, plus a base rate of $89.00.
Answer:
The function would be linear because the rate of change is constant.
Step-by-step explanation:
Given
[tex]Base= \$89.00[/tex]
[tex]Rate = \$0.10[/tex] per minute
See attachment for complete question and options
First, we write the function that calculates the cost (C(t)) for t minutes.
This is calculated as:
[tex]Cost = Base + Rate * t[/tex]
[tex]C(t) = 89.00 + 0.10 * t[/tex]
[tex]C(t) = 89.00 + 0.10t[/tex]
Rewrite as:
[tex]C(t) = 0.10t + 89.00[/tex]
A function that has the above format is referred to as a linear function which has the general format
[tex]f(x) = mx + b[/tex]
Where
m represents the slope/rate and it is constant
From the list of given options, (a) is correct.

Answer:
i believe it is 73 degrees
Step-by-step explanation:
Answer:
73°
Step-by-step explanation:
All interior angles of a triangle add up to 180°
We are given the angle measure of 17°. Since the triangle is a right triangle, it's safe to assume that the second angle is 90°.
90 + 17 = 107
180 - 107 = 73
The third angle should be 73°. Hope this helps!

Verizon charges $200 to start up a cell phone plan. then there is a $50 charge each month. what is the total cost for .x months
Answer:
200 + 50x
Step-by-step explanation:
depending on what x is, you multiply x by 50 and add 200, since 200 is the start up fee and the constant. the 50 dollars per month is a variable, since the more months you own the plan, the more money it would cost.

The amount paid for different weights of oranges at a farmer’s market are shown below.
Answer:
8
Step-by-step explanation:
Well just looking at the problem you can take the first line of data (2 pounds of oranges for $3) and divide that to get how much one orange would be.
So:
$3.00 / 2 = $1.50
So now we have :
1 pound of oranges = $1.50
With this info we can take the $12 on the fourth line and divide it by the price of one pound of oranges ($1.50).
Like so:
$12.00 / $1.50
=
8
We can check this by inputting the 8 on the ?
If we do so we get 8 (8 pounds of oranges) x $1.50 (Price per 1 pound of oranges) = $12.00, which matches up with the $12 price the problem has given us.
Hope this helps!

Answer:
5 cookies left
Step-by-step explanation:
First you make the fraction equal by multiplying them
2/3 multiply both numerator and denominator by 4
= 8/12
Now you divide 60 by 12 to find the amount to make the denominator 60
60 divided by 12 = 5
8/12 multiply both numerator and denominator by 5
= 40/60
So now we know the amounts

Evaluate the following expression: 8x - 6 - 7y + 3 use x=3 and y=6
Answer:
-27
Step-by-step explanation:
8x - 6 - 7y + 3
X = 3 Y = 6
8(3) - 6 - 7(6) + 3
8 x 3 = 24
7 x 6 = 42
24 - 6 - (42 + 3)
(24 - 6) - 45
