Justin is evaluating the expression 12.53.8x, when x is 7.9.
12.5+3.847.9)
16.3(7.9)
128.77
What was Justin's error?
Justin should have multiplied 12.5 and 7.9 first.
Justin should have added 12.5 and 7.9 first.
Justin should have multiplied 3.8 and 7.9 first.
O Justin should have added 3.8 and 7.9 first.
Answer:
C.) Justin should have multiplie 3.8 and 7.9 first.
Step-by-step explanation:
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
Dolores spent $ 13.00 of the $20.00 in her wallet. Which decimal represents the fraction of the $20.00 Dolores spent?
A. 0.35
B. 0.13
C. 0.07
D. 0.65
Answer:
In order to find the fraction of the 20 dollars that has been spent, we have to divide the amount spent by the total amount. So 0.65 is the fraction of 20 that is spent.

A chemist measures the boiling point of a sample of benzene as 79.8 degrees Celsius. The actual boiling point is 80.1 degree Celsius. Round to the nearest hundredth of a percent, what is the percent error in the boiling point for the sample? Put the % sing after your numbers and do not put spaces in your answer.
Answer:
-0.375%
Step-by-step explanation:
Here, we want to calculate the percentage error
Mathematically;
% error = error/true value * 100%
error= the difference between the true value and the calculated
That is;
79.8-80.1 = -0.3
% error = -0.3/80.1 * 100%
% error = -0.375%

I need help with this question.
Answer:
59
Step-by-step explanation:
We know that all the angles must add up to 180
so we have
38+2b-20+b-15=180
solve for b
3b+3=180
3b=177
b=59
Answer:
b=59
Step-by-step explanation:
angles in the triangle add up to 180
this would mean that
38 +2b-20 + b-15 = 180
if we simplify this then it would be
3+3b= 180
rearrange
3b = 177
b = 59

Find the equation of straight line passing through the point:
a) (4,8) and parallel to the line 3x+y=17
b) (2,3) and perpendicular to the line y=2x+13
I need the answers ASAP please!
Answer:
See solution below
Step-by-step explanation:
Standard equation of a line in point slope form is expressed as y-y0 = m(x-x0)
m is the slope
c is the intercept
Fr the equation 3x+y = 17
y = -3x+17
m = -3
Given the point (4,8)
The equation of the line is expressed as;
y - 8 = -3(x-4)
y - 8 = -3x + 12
y + 3x = 12+8
y+3x = 20
This gives the required equation
For the equation y = 2x + 13
Slope m = 2
Since the line is perpendicular to the unknown line;
M = -1/2
Given the point (2, 3)
Get the equation
y - 3 = -1/2(x - 2)
2(y-3) = -(x - 2)
2y-6 = -x+2
2y+x = 2 + 6
2y+x = 8
This gives the required equation
What are the coordinates of each point after quadrilateral ABCD is rotated 270° about the origin?
Answer:
A'(1, -1), B'(3, -2), C'(3, -4), D'(1, -5)Step-by-step explanation:
The rule for a rotation by 270° about the origin is:
(x, y) → (y, −x)Coordinates of ABCD:
A(1, 1), B(2, 3), C(4, 3), D(5, 1)Coordinates of the image:
A'(1, -1), B'(3, -2), C'(3, -4), D'(1, -5)Answer:
A'(1,-1) , B'(3,-2) , C'(3,-4) , D'(1,-5)

Step-by-step explanation:
To find the correct measurement of the angel the sum of the interior angels needs to equal 360°. Angels where the lines intersect with the circle would be both 90°. ( If that makes sense.)
90°+90°=180
180°+73°= 253°
360°-253°= 107°
The same for the second one. (those two angles would also be 90° each.)
90°+90°=180°
180°+57°=237°
360°-237°=123°

Find the product (2y - 6)^2
The product (2y - 6)² of the algebraic expression gives 4y² - 24y + 36
How to find the product (2y - 6)²?An algebraic expression is an expression that is made up of variables and constants, along with algebraic operations like addition, subtraction, square root, etc.
The product (2y - 6)² can be written as:
(2y - 6)² = (2y - 6)(2y - 6) (clear the parenthesis)
= 2y(2y - 6) -6(2y - 6)
= 4y² - 12y - 12y + 36
= 4y² - 24y + 36
