Answer:
Taji has a total of 56 quarters.
Step-by-step explanation:
Let <em>x</em> be the number of quarters that Taji has.
Amount in terms of quarter 
Let <em>y</em> be the number of dimes that Taji has.
Amount in terms of quarter 
As per question statement:
Total amount is $18.20 as given in the question statement.
Solving equations (1) and (2):
Multiplying equation (1) by 10 and subtracting from equation (2):
<em>x </em>is the number of quarters that Taji has.
So, Taji has a total of 56 quarters.
Answer:
y=49/9
Step-by-step explanation:
Distribute 3 with 3y and -5
3 times 3y is 9y
3 times -5 is -15
So the equation now looks like this:
9y-15=34
Add 15 on both sides:
9y=49
Divide 9 on both sides
So y=49/9
Since there is no common value to divide by y is 49/9
If you want the decimal version it is 5.44=> (=> meaning continuing forever)
Hope this helps!
the number is 8 because the equation is (x * 3) + 4 so replace x with (8) and its (8 * 3) + 4 = 28 :)
Answer:
a. 3
Step-by-step explanation:
An independent variable is the variable that is changed in an experiment to test its effects on the dependent variable. i.e. inputs
A dependent variable is the variable being tested, measured or predicted in an experiment. I.e a outcome
In this case, the the effects of the amount tutors are paid a week before exam, the amount of sleep before exam and the number of study hours are input variables to determine or predict a students score in exam
The independent variables are;
x1 =represents the amount paid to a tutor (in dollars) in the week before the exam
x2 = represents the number of hours of sleep in the week before the exam
x3 = number of study hours in the week before the exam
The dependent variable is the exam score
B0, B1, B2,B3, B4 are coefficients
The answer is C. Because the side triangles inner corner is 51 so the inner corner of the big train fled are 129. 129 + 20 equals 149 and 180 - 149 equals 31.
