Answer:For example, choice A is incorrect because if the value of 10x + 3 were 4, then it would follow that x = 0.1, and the value of 5x + 6 would be 6.5, not 10.
Step-by-step explanation:
The answer is
283a + 5 = 12
subtract 5 from both sides
3a = 7
divide by 3 on both sides to isolate "a"
a = 7/3
Substitute 7/3 for "a" in the second equation
6(7/3) + 14
6 multiplied by 7/3 = 42/3 = 14
14 + 14 = 28

If f(x) = 2(34) + 1, what is the value of f(2)?
Answer:
34.5 i thiNK
Step-by-step explanation:
PEMDAS
2 times 34 is 68 plus 1 is 69
Therefore for it to be equal f would have to be half of 69 which is 34.5

which number is closest to - 67 (square root)?
A. -9.2
B. -9.4
C. -7.9
D. -8.1
Answer:
D. -8.1
Step-by-step explanation:
Squares of natural numbers are
{1,4,9,16,25,36,49,64,81,...}, which are squares of {1,2,3,4,5,6,7,8,9,....}
As 65 lies between 64 and 81, square root of
65 lies between 8 and 9 Further, 8.1 2 = 65.61, and as 8.02 = 64, the square root of 65 lies between 8.0 and 8.1.

John walked 9 5/8 miles at an average speed of 1 3/4 MPH. How long did it take John to walk this distance?
Answer:
5 hours and 30 minutes
Step-by-step explanation:
Convert all fractions to decimals for easier division
9 and 5/8 = 9.625
1 and 3/4 = 1.75
Then divide 9.625 by 1.75 to get the hours amount
9.625 / 1.75 = 5.5
0.5 of an hour is 30 minutes, so the final answer is 5 hours and 30 minutes
Answer:
5.5 hours
Step-by-step explanation:
9.625/1.75=5.5hr
WILL GIVE BRAINLY PLEASE HELP!!!!!! In this triangle, what is the value of x? enter your answer, rounded to the nearest tenth, in the box.
Answer:
x ≈ 67.1
Step-by-step explanation:
The side adjacent to x° is given, along with the hypotenuse. That suggests the relevant trig relation is ...
Cos = Adjacent/Hypotenuse
cos(x°) = 28/72 = 7/18
The angle is found from the cosine using the inverse cosine function:
x° = arccos(7/18)
x° ≈ 67.1°

Write two equations-one in logarithmic form and one in exponential form-that represent the
statement: "the natural logarithm of 10 is y".
Expressions can be expressed in logarithmic forms, and in exponential forms
The two equations are [tex]\ln(10) = y[/tex] and [tex]10 = e^y[/tex]
How to determine the expressions.The statement is given as "the natural logarithm of 10 is y".
The logarithmic expression of the above statement is:
[tex]\ln(10) = y[/tex]
Rewrite the above expression, as an exponential equation

A motorcycle travelled 302 km. It travels an average of 14.9 km on a litre of petrol. Without using a calculator, estimate the number of litres of petrol used.
Answer:
20.268liters
Step-by-step explanation:
thereby the total distance is 302km and 1liter of fuel is use on 14.9
thus
1 litter = 14.9km
x. 302km
Let find the value of x
14.9kmx = 302kmliter
14.9km. 14.9km
like terms cancel each other

An online store holds a sale. Of the 500 customers who make purchases during the sale, 120 use a coupon. What percent of the customers do not use a coupon?
Total no of customers = 500
Used coupon = 120
Not used coupon = 500 - 120 = 380
We need to find the percentage of the customers do not use a coupon. It can be given by :
380/500×100
So, there are 76% of the customers that do not use a coupon.
Which expression correctly represents "nine less than the quotient of a number and four, increased by three"? StartFraction n Over 4 EndFraction minus 9 3 StartFraction 4 Over n EndFraction minus 9 3 9 minus StartFraction n Over 4 EndFraction 3 9 minus StartFraction 4 Over n EndFraction 3.
Answer:
n/4-9 +3
Step-by-step explanation:
to answer this question we have to analyze the information given.
The quotient of a number means the result of the division of 2 numbers.
In this case the numbers are: a number (n) and 4 . n/4
Nine less than that quotient means we have to subtract 9 to the quotient.
n/4-9
Increase by three: we simply have to add 3
n/4-9 +3

A plant has an initial height of 2 inches and grows at a constant rate of 2 inches each month. A second plant that also grows at a constant rate has an initial height of 1 inch and is 29 inches tall after 1 year. After how many months are the plants the same height?
Answer:
Answer:4.8 monthsStep-by-step explanation:First, let's write down the information that we are given.Plant A: Initial Height: 3 in.Constant Rate of Growth (CRG): 2in/month (2 inches per month)Plant B:Initial Height: 1 in.CRG: 29in/year (29 inches per year)We can see that Plant B grows 29 inches per year, so lets convert Plant B's 'CGR' to months.Plant B - Divide by 12 (12 months in a year)29/12 in/yearNow, Lets put these into equations:Plant A: y = 2x + 3Plant B: y = 29/12 x + 1Now, set these two equations together and solve for x.2x + 3 = 29/12 x + 12 = 5/12 x4.8So, after 4.8 months, the plants will be the same height.
