Answer:
a = 5
Step-by-step explanation:
When the coefficients of the variables are equal with different constants, then you will get an equation which is never true.
For this particular equation, when a on the right side has a coefficient of 5, you will get the equation: 4(a - 2) + a = 5a - 4.
When you distribute the factors in the parenthesis and add the like terms of a together, 4(a - 2) + a will become 5a - 8. This is because 4(a - 2) + a = 4(a) + 4(-2) + a = 4a - 8 + a = 5a - 8.
Now when you simplify 5a - 8 = 5a - 4 by subtracting 5a from both sides, you will get an equation with unlike constants. For instance 1 = 0.
Now:
5a - 8 = 5a - 4
-5a -5a
-8 = -4
This is never true, so therefore, there is no solution.
Answer:
It is 5

What is the quotient of x and three increased by 12 = 20
Answer:
x= 24
Step-by-step explanation:
Quotient means divide, increased means add
x/3 + 12 =20
Subtract 12 from each side
x/3 +12-12 = 20-12
x/3=8
Multiply each side by 3
x/3 * 3 =8*3
x= 24

Solve x-5>-12.
A. X> -7
B. x < -17
C. x > -17
D. x < -7
PLEASE HELP ME
Answer:
A. X>-7
Step-by-step explanation:
So the equation is
X-5>-12
You add 5 on both sides to get the X by itself. You add it because you have to get rid of the -5 and to get to 0 you would add 5.
Which leaves you with X>-7
Answer:
A.) [tex]x>-7[/tex]
Step-by-step explanation:
Solve this the way you would solve an equation: isolate the variable.
Use inverse operations. Add 5 to both sides:
[tex]x-5+5>-12+5\\\\x>-7[/tex]
Since this can't be simplified further, x is greater than -7.

The table shows the prices of some candy items at a store. Jake selected 1.6 pounds of Fruit Chews and 2.6 pounds of Jelly Beans. The sales tax for his purchase was $0.52. .Item. .Price Per Pound. .Fruit Chews. $4.70 .Jelly Beans. $2.35 .Chocolate. $3.50 .If Jake had $25 to spend at the candy store, how much money did Jake have left after his purchase?
Answer:
The amount of money Jake had left after his purchase is $10.85
Step-by-step explanation:
The amount of Fruit Chews Jake selected = 1.6 pounds
The amount of Jelly Beans Jake selected = 2.6 pounds
The sales tax = $0.52
The amount of money Jake had to spend = $25
The table of values are;
Price Per Pound [tex]{}[/tex]
Fruit Chews = $4.70
Jelly Beans = $2.35
Chocolate = $3.50
The amount of money Jake had to spend $25
The total amount of the candies Jake bought = 1.6 × $4.70 + 2.6 × $2.35 = $13.63
The total amount Jake spent = The total amount of the candies Jake bought + The sales tax
The total amount Jake spent = $13.63 + $0.52 = $14.15
The amount of money Jake had left after his purchase = The amount of money Jake had to spend - The total amount Jake spent
The amount of money Jake had left after his purchase = $25 - $14.15 = $10.85
The amount of money Jake had left after his purchase = $10.85.
The table below represents the number of hours a student worked and the amount of money the student earned. What is the initial amount this student is paid? (Base pay, when number of hours, h = 0) I’LL PAY YOU 30 DOLLARS IN CASHAPP RIGHT NOW WHEN YOU DO IT!
The initial amount this student is paid is 0 and this can be determined by using the two-point slope form of the line.
Given :
The given table represents the number of hours a student worked and the amount of money the student earned.
The following steps can be used in order to determine the initial amount this student is paid:
Step 1 - The two-point form of the line can be used in order to determine the initial amount this student is paid.
Step 2 - So, the linear equation that represents the given situation is:
[tex]\rm \dfrac{d-50}{h-8}=\dfrac{93.75-50}{15-8}[/tex]
Step 3 - Simplify the above expression.
[tex]\rm \dfrac{d-50}{h-8}=6.25[/tex]
d - 50 = 6.25h - 50
d = 6.25h
Step 4 - Now, substitute the value of (h = 0) in the above expression.
d = 0
Therefore, the correct option is D) There is no base pay.

You guys are life savers but does anyone know the answers to these questions? I’m so confused rn
Answer:
The third choice
Step-by-step explanation:
We need to find the slope and y-intercept of the line and then put it into y = mx = b form. To find the slope, pick a point on the line; I will use (-2, 5); count how many units up you need to go to get to the next point on the line, which in this case it would be 3. The count how many to the right or left you would need to go, which is 1 to the left. Moving left means a negative, so it is -1. Your slope fraction would be [tex]\frac{3}{-1}[/tex] , since slope is rise over run. You can sub this fraction in for m in y = mx + b, which will give you a revised equation of y = -3x = b. To find the y intercept, or b, just find the point where the line crosses the y-axis, which is -1. So, the equation is now y = -3x - 1.The correct answer is third choice.

A grocery store is selling peaches for $0.98 per pound. Is this a function or Not function
Answer:
This is a function. Use y=mx+b equation
Step-by-step explanation:
To find the x and y values, simply plug in 0.98 to m. For every pound of peaches, you pay $0.98. The equation would be y=0.98x, where x is the number of pounds of peaches and y is the total cost.

The probability that Terry buys a sandwich is 0.4.
The probability that Terry gets the bus is 0.9.
Assuming the events are independent, what is the probability that Terry buys a sandwich and gets the bus?
Answer:
The probability that Terry buys a sandwich and gets the bus is 0.36
Step-by-step explanation:
When two events are called independent, it means that the happening of one event doesn't affect the happening of other event.
Let A be the event that Terry buys a sandwich
Let B be the event that Terry gets the bus
Then
[tex]P(A) = 0.4\\P(B) = 0.9[/tex]
When two events are independent, their probabilities are multiplied i.e.
[tex]P(A\ and\ B) = P(A) * P(B)\\= 0.4 * 0.9\\= 0.36[/tex]
Hence,
The probability that Terry buys a sandwich and gets the bus is 0.36
identify an equation in slope-intercept form the line parallel to y=-3x+7that passes through (2,-4)
Answer:
y=-3x+2
Step-by-step explanation:
Same slope = parallel. You can aso double check this answer by either graphing using the desmos online graphing calculator or by plugging in the point into the equation y = -3(2) + 2 --> y = -6 + 2 --> y = -4, so we are correct.
Answer:
y=-3x+2
Step-by-step explanation:
In this equation the slope is the same as the original equation (-3), but has a different y-intercept meaning that this line is parallel. As for satisfying the requirement that the line is parallel and passes through (2,-4), I plugged the coordinates into the equation y=-3x+b to get -4=-3(2)+b, and then found what b would have to equal to make the equation true.
