Answer:
Zero
Step-by-step explanation:
First you do (3-2) which is one then you multiply that by five which gives you 5. Then you will subtract 5 from each side and that leaves you with 15a=0. Divide both sides and you’ve got zero
The explanation is on the picture please help me with my math
Answer:
Step-by-step explanation:
1. add 8 to both sides to get d=25
2. subtract 12 from both sides to get v=-17
3. add 2 to get b=-9
4. subtract m to get -16-m=71 then add 15 to get -m=87 then divide both sides by - to get m by itself so m=-87
5. subtract a then subtract 29 to get -a=-105 then divide it by - to get a=105
6. add 14 to both sides to get y=12

A teacher plans to buy air fresheners that cost $3.50 each. If the teacher can spend no more than $10 on the air fresheners and has a $3 discount coupon, which inequality represents the number of air fresheners, x, the teacher can buy?
Answer:
Step-by-step explanation:
We need to create an equation to represent how many air fresheners the teacher can buy.
Teacher has $10 and a $3 discount coupon which would give her an extra $3 to spend. Each air freshener is $3.50.
x = number of air fresheners
($10 + $3) / $3.50 = x can be written as $13/$3.50 = x
We add $10 and $3 because that gives us the total amount she has to spend.
We divide by $3.50 because that is the cost of each air freshener. The result is the number of air fresheners she can buy.
In this case.
$13/$3.50 = x
3.71 = x BUT we can't buy part of an air freshener, so she can purchase 3 air fresheners.
Solve for X please.
Answer:
x = -4
Step-by-step explanation:
12 + 8 + 2 = 22
So x will be negative
12 - 4 = 8
-4 + 8 = 4
2
8 + 4 + 2 = 14
Answer:
x= -4
Step-by-step explanation:
Essentially all that one needs to do is add up all the given values,
because each part, each segment of the line is a specific value
When added up, they create the whole line.
JI = 12+x
IH= x+8
HG = 2
JG = 14
so add up all the segments
JI + IH + HG = JG
12 +x + x + 8 + 2 = 14
simplify, and solve with inverse operations,
2x + 22 = 14
2x = -8
x = -2
check by substituting back into the problem
JI = 12 +x
12 - 4
=8
IH = x +8
-4 +8
=4
HG =2
JI + IH + HG = JG
8 + 4 + 2 = 14

the angles of a qaudileteral are x,2x,100 and 110 degress find the value of 2x
Step-by-step explanation:
Hey there!!!!
We generally sum up all the angles to get 360° as per given in our question.
Here, in your question, we have values as,
x, 2x, 100°, 110°.
(We have 360° as the sum quadrilateral).
So, x° + 2x° + 100°+110° = 360°
3x°+210°= 360°
3x° = 360° - 210°
or, 3x° = 150°
[tex]x = \frac{15 0 }{3} [/tex]
Therefore the measure of 2x is (2×50)°=100°.
Hopeit helps...
Answer:
X=50; 2x=2×50=100
Step-by-step explanation:
sum of angles in a quadrilateral is 360°
Therefore; x+2x+100+110=360;
3x+210=360;
3x=360-210;
3x=150;
divide both sides by the co-efficient of x;
3x/3=150/3;
x=50;
therefore 2x=2×50;
2x=100.

The company plans to sell the video game console at a loss in order to increase its sale. It will make up for the loss from profits made from the sales of Games for the system. The company will lose $50 for each console it sells and earn a profit of $15 for each game sold for the system. Write an equation that can be used to determine T the total amount the company will earn from a customer who buys a consul and G games
Answer: [tex]T= 15 G - 50[/tex]
Step-by-step explanation:
As per given,
Total earning = (profit per game) x (Number of games) -(loss in consul)
Let T be the total amount the company will earn from a customer who buys a consul and G games.
Since, loss in consul = $50
profit per game = $15
Then required equation will be :
[tex]T= 15 G - 50[/tex] , it determines T the total amount the company will earn from a customer who buys a consul and G games.

the same hourly wage, how many hours would he have to work the next week to earn
$83.20?
$145.60 / 7 hours = $20.8 / hour
$83.20 / $20.8 = 4 hours
Jose would have to work 4 hours to make $83.20

What is squaring of numbers ?When we multiply a number by it self once the number is squared.We add 1 to the exponent.We must also remember squares of numbers from 1 - 20 for us to solve questions related to squares and square roots.
For example - (5)² is 25. { 5² is 5 multiplied by it self once (5×5)}.
Also square root of 25 is 5.We can find square root of any given perfect square number by prime factorisation.
According to the given question we have find what is the square of half.

Every weekday after tennis practice, Will buys either a carton of milk or a bottle
of power drink.
Suppose that m is the number of cartons of milk that Will purchased during
the last month. His total cost for beverages in dollars last month can be
represented by the algebraic expression 2m + 3 (20 – m).
Which of the following statements are true? Select all that apply.
The cost of the power drink is $3 per bottle,
Will purchased 20 more bottles of power drink than cartons of milk.
Will purchased a total of 20 beverages during the last month.
The total amount Will spent on power drinks was $60
An equivalent expression for the total cost of Will's beverages during this month is
60 - m dollars
Will purchased 20 more cartons of milk than bottles of power drink
Answer:
The correct options are;
The cost of milk powder is $3 per bottle
An equivalent expression for the total cost of Will's beverages during this month is 60 - m dollars
Step-by-step explanation:
The given information are;
The items Will buys every weekday after tennis practice = A carton of milk or a bottle of powder drink
The number of milk purchased during the month = m
Will's total cost for beverages in dollars last month = 2·m + 3·(20 - m)
1) Therefore, given that the total amount is factored in dollars, we have;
2·m and 3·(20 - m) are dollar amounts, while, m is a quantity;
Therefore;
Where;
2·m = The total cost of the cartons of milk, then the factor 2 represents $2.00 which is the cost per carton of milk
Similarly, 3·(20 - m) can be said to represent the total cost of the powder drink then the factor 3 represents $3.00 which is the cost per powder drink and the factor (20 - m), represents the number of powder drink Will buys for the month
From which we found the cost of milk powder = $3.00 per bottle
2) The expression, 2·m + 3·(20 - m) simplifies to 2·m + 60 - 3·m, which gives;
2·m + 60 - 3·m = 60 - m which is an equivalent expression for the total cost of Will's beverages for the month.

4. The difference of two integers is 9. Five times the smaller is 7 more than 3 times the larger. Find the numbers.
Answer:
x = 26 and y = 17
Step-by-step explanation:
x is the larger number and y is the smaller number
the difference is 9 ⇒ x - y = 9
Five times the smaller is 7 more than 3 times the larger ⇒ 5y - 3x = 7
x - y = 9 ⇒ x = 9 + y (1)
substitute x = 9 + y in 5y - 3x = 7
5y - 3(9 + y) = 7
5y - 27 - 3y = 7
2y = 7 + 27
2y = 34
y = 34/2
y = 17
x = 9 + 17
x = 26
