X + 3y = 5
-x + 6y = 4
Add them together

9y = 9 = y = 1
______________________
x + 3(1) = 5
x + 3 = 5
x = 5 - 3 = 2
X = 2

The answer would be X = 2 and Y = 1

A taxi driver's flat rate of $3 plus an additional $0.05 per mile car will only take taxi home if cost is under $10 under otherw
mixas84 [53]

Step-by-step explanation:

we can model the expression for the inequality as

given the flat rate is $3

let the additional mile be x

hence

3+0.05x<10

step two:

let us proceed to solve for x

3+0.05x<10

0.05x<10-3

0.05x<7

divide both sides by 0.05

x<7/0.05

x<140    

let us plug in 15 into the expression and see if the cost is under $10

3+0.05(15)<10

3+0.75<10

3.75<10

from the analysis, carl will have to take the taxi since cost is less than $10 i.e $3.75

A continuous variable _____ (does/does not) allow fractional amounts. a discrete variable _____ (does/does not) allow fractional
Mademuasel [1]

A continuous variable does allow fractional amounts. a discrete variable  does not allow fractional amounts.

Which variables require boundaries, also known as real limits, in their measurement scales?

A researcher must utilize genuine limits, which are boundaries that are exactly halfway between adjacent categories, to specify the units for a continuous variable.

What distinguishes a ratio scale from an ordinal scale?

  • Ordinal: The information is classifiable and rankable.  The data can be equally spaced, categorized, and rated.
  • Ratio: The data is evenly spaced, categorizable, rankable, and has a natural zero.

For continuous data, what kind of data would you use?

Line graphs, skews, and other data analysis techniques are used to measure continuous data. One of the most popular kinds of continuous data analysis is regression analysis.

Noah's balance will be given as follows:
balance=(Feb 4th cash deposit)-(Feb 5th ATM withdrawal)+(check deposit)
Cash deposit=$275
ATM withdrawal=$60
Check deposit=$410.21
Therefore, our new balance will be:
balance=275-60+410.21=$625.21

PLEASE HELP!!!! I’m stuck<br> What is the measure of What is the measure of
choli [55]

Answer:

∠A = 94º

∠C = 86º

Step-by-step explanation:

You just need to know that the sum of the two angles in a parallelogram must be equal to 180º. Let's make an equation.

(5y-3)+(3y+27)=180

Solve;

5y-3+3y+27=180

Combine like terms;

8y+24=180

Subtract 24

8y=180-24

8y=156

Divide by 8

y=\frac{156}{8}

Simplify.

y=\frac{39}{2}

Replace;

∠A = 5y-3

5(\frac{39}{2})-3\\ \frac{195}{2}-3\\ \frac{195-2*3}{2}\\

\frac{195-6}{2}

\frac{189}{2} =94.5≅ 94

----------------------------------------------------------------------------------------------

∠C =

3y+27\\3(\frac{39}{2})+27

\frac{117}{2}+27

\frac{117+27*2}{2}

\frac{117+54}{2}

\frac{171}{2}=85.5≅86
