What is the solution to 34x+85=3(13x+7)
Answer:
x=12.8
Step-by-step explanation:
34x+85=39x+21
34x-39x=21-85
-5x = -64
x = -64/-5
x = 12.8
Answer:
x = 34/5
Step-by-step explanation:
Just solve the equation
[tex]34x + 85 = 3(13x + 17)\\34x + 85 = 39x + 51\\85 - 51 = 39x - 34x\\34 = 5x\\x = 34/5[/tex]

The manager of a summer camp has 14 baseballs and 23 tennis balls. The manager buys some boxes of baseballs with 12 baseballs to a box and an equal number of boxes of tennis balls with 16 tennis balls to a box. Write an expression to represent the total number of balls. PLEASE PLEASE HELP I NEED IT DONE TONIGHTTT
Answer:
u want full equation?
Step-by-step explanation:
Answer
baseballs:14+12n
tennies balls: 23+16n
14+12n+23+16n
14+23+12n+16n
(14+23)+(12n+16n)=37+28n
(n= the number of boxes of each type)
Step 1: We write expressions for the total number of baseballs and tennis balls
Step 2: We find an expression fr the total number of balls:
We combine the above expressions:
We use the Commutative Property:
We combine like terms:
( the answer is 37+28n)

What would be the height of 1000 Canadian Dimes?
The height of 100 Canadian dimes is 1220 millimeter.
What is a expression? What is a mathematical equation? What is Equation Modelling?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have 1000 Canadian dimes.
Assume that the height of 100 Canadian dimes is [x] mm. Then, we can write -
[x] = 1000 x 1.22
[x] = 1220 mm
Therefore, the height of 100 Canadian dimes is 1220 millimeter.

Oil prices are projected to increase by 75% by next May. A quart of oil currently costs $2.15. What is the projected cost of a gallon of oil next May? Round your answer to the nearest hundredth.
Answer:
Future cost per gallon= $15.05
Step-by-step explanation:
Giving the following information:
Oil prices are projected to increase by 75% by next May. A quart of oil currently costs $2.15.
We know that 1 quart equals 0.25 gallons.
First, we will determine the actual cost per gallon.
Actual cost per gallon= 2.15*4= $8.6
Now, the cost for May:
Future cost per gallon= 8.6*1.75
Future cost per gallon= $15.05
Answer:
15.05

Suppose there are 28,200,000 small businesses in the economy today. Twenty-five percent of those businesses have no employees. What is the number of businesses in the economy with no employees?
Answer:
the number of businesses with no employees is 7,050,000
Step-by-step explanation:
The computation of the number of businesses in the economy have no employees is shown below:
Given that
There are a total of 28,200,000
Out of which 25% of those businesses have no employees
So, the number of businesses in the economy is
= 28,200,000 × 25%
= 7,050,000
Hence, the number of businesses with no employees is 7,050,000

Is each line parallel, perpendicular, or neither parallel nor perpendicular to a line whose slope is 2/5?
line n, with slope -5/2
line m, with slope 5/2
line p, with slope 2/5
Answer:
Step-by-step explanation:
n is perpendicular. - 1/(2/5) = - 5/2. n is the negative reciprocal of the given line.
m is neither.
p is parallel to the given line. For example y = 2/5x
and y = 2/5 x + 9 are parallel to each other.

Joan wants to start an IRA that will have $860,000 in it when she retires in 29-years. How much should she invest annually in her IRA to do this if the interest is 8% compounded annually?
Answer:
Annual deposit= $8,271.94
Step-by-step explanation:
Giving the following information:
Future Value (FV)= $860,000
Number of periods= 29 years
Interest rate= 8% = 0.08
To calculate the annual deposit, we need to use the following formula:
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
A= (860,000*0.08) / [(1.08^29) - 1]
A= $8,271.94

A plumbing company charges $35 per hour plus a $25 travel charge for a service call. Another plumbing company charges $40 per hour for a service call with no travel charge. Solve the equation 35h+25=40h to find how many hours h a service call must be for the two companies to charge the same amount.
__ hour(s)
Answer:
5 hours
Step-by-step explanation:
35h + 25=40h
implies 25=40h-35h
25=5h
dividing both sides by 5,
h=5

At a birthday party pizzas and sodas were purchased for the kids. The number of sodas bought was two more than three times the number of pizzas. Pizzas cost $9.50 each and sodas cost $1.25 each. (c) A total of $68.75 was spent on pizza and sodas at the party. Let n be the number of pizzas purchased. Set up an equation involving n that models the scenario. Solve it and state both the number of pizzas and the number of sodas that were bought.
Answer:
5 pizzas and 17 sodas were bought
Step-by-step explanation:
Here, we want to get the number of pizza and sodas bought
Let n be the number of pizzas bought
we are told that the number of sodas bought was 2 more than 3 times the number of pizzas
So the number of sodas will be;
3n + 2
So let’s have the equations based on the prices;
pizzas cost $9.50, soda cost $1.25
Thus;
9.5n + 1.25(3n + 2) = 68.75
9.5n + 3.75n + 2.5 = 68.75
13.25n = 68.75 - 2.5
13.25n = 66.25
n = 66.25/13.25
n = 5
Number of pizzas bought is 5
number of soda is 3n + 2 = 3(5) + 2 = 15 + 2 = 17

Kenji is decorating papers with a total of 15 heart stickers and 12 star stickers for the child he is babysitting. If he wants to make all the papers identical, with the same combination of heart and star stickers and no stickers left over, what is the greatest number of pages Kenji can decorate?
Answer: The greatest number of pages Kenji can decorate = 3
Step-by-step explanation:
Given: Total heart stickers = 15
Total star stickers =12
If all the papers identical, with the same combination of heart and star stickers and no stickers left over.
Then the greatest number of pages Kenji can decorate = GCD(15,12) [GCD=greatest common divisor]
Since 15 = 3 x 5
12=2 x 2 x 3
GCD(15,12) =3
Hence, the greatest number of pages Kenji can decorate = 3
