1. The sum of Teresa's and Cathy's weight is
118 pounds. Teresa weighs 26 pounds more
than Cathy. If Teresa's weight is T and Cathy's
weight is C, which of these systems of
equations best represents this relationship?
A) T+C = 118
T= 26
B) T+C = 118
T +26=C
C) T+C=64
T-C= 26
D) T=C + 118
T=C+26
E) None of the above
Answer:
d
Step-by-step explanation:
E is ththe answer
the first equation should be T + C = 118 and the second equation should be C + 26 = T
none of these equations are correct

Angles and Parallel Lines
Answer:
a = 6
b = 25
Step-by-step explanation:
As alternative angles in a parallel line are equal to each other,
5a = 3a + 12
So, now we can find the value of a by making "a" the subject.
5a - 3a = 12
2a = 12
Divide both sides by 2.
a = 6°
And now let us find the value of b.
We know that interior angles in a triangle are added up to 180°.
So,
2b + 4b + 3a + 12 = 180
We can replace a with 6 and then we can make "b" the subject to find the value of b.
Let us solve it now.
2b + 4b + 3 × 6 + 12 = 180
6b + 18 + 12 = 180
6b + 30 = 180
6b = 180 - 30
6b = 150
Divide both sides by 6.
b = 25°
. Paul bought 5 books for $30.85. About how much did each book cost? .
ESTIMATE UR ANSWER PLS AND SHOW UR WORKK!
Answer:
Each book cost about $6.20 per book, or in more general terms, $6 per book.
Step-by-step explanation:
If you round the $30.85 total of 5 books to $31 and divide that by 5, you get an average cost of $6.20 per book.
If you need a more general answer, you could round the $30.85 total of 5 books to $30 and divide that by 5, you get an average cost of $6 per book.

Slope Formula[tex]\cfrac{y2-y1}{x2-x1}[/tex]
Y2 and Y1 represent the y-coordinates, and X2 and X1 represent the x-coordinates.
We are given the points:

Using this formula, we plug in the given points like so:
[tex]\cfrac{12-6}{7-4}[/tex]
Now we can simplify:
[tex]\cfrac{12-6}{7-4}=\cfrac{6}{3} =2[/tex]

so each person will have 7 oranges.
What is the value of X
Answer:
X = 10.4
Step-by-step explanation:
Since the angle is a 90 degress angle we can assume that
39 + (5x-1) = 90 degrees.
Therefore we can subtract 39 from both sides which will give us
5x-1=51
Add 1 to both sides
5x = 52
Divide both sides by 5
x=52/5
The answer is
X = 10.4

Does the point make the equation true ?
Answer:
(3, 4) does not make y = .5x + 1.5 true.
Step-by-step explanation:
y = .5x + 1.5
(3, 4)
Substitute 3 for x and 4 for y and see if the two sides of the equation are equal to each other.
4 = .5(3) + 1.54 = 1.5 + 1.54 = 3Since 4 ≠ 3, the point (3, 4) does not make the equation y = .5x + 1.5 true.

The diameters of two circles are 12 and 9 what the difference in square centimeters between the areas of the two circles
Step-by-step explanation:
Area of circle= π(d/2)²For 1st Circle, A1= 36π
For 2nd Circle, A2= 81π/4
A1-A2 = 63π/4
π = 22/7
=49.5unit²
The differences in the areas of circles in square centimeters is 49.455
Formula for area of circle
[tex]A = \pi r^{2}[/tex]
Where,
A is the area of circle
r is the radius of circle
and π = 3.14
What is radius of a circle ?Radius of circle is the distance from the center of the circle to any point on it's circumference. It is calculated as :
[tex]Radius = \frac{diameter}{2}[/tex]
According to the given question
Diameter of one circle is 12cm and diameter of another circle 9cm.
Area of circle with diameter 12 cm = [tex]\pi (\frac{12}{2} )^{2}[/tex] = [tex](3.14)(6)^{2}[/tex] = 113.04 square cm
Area of circle with diameter 9 cm = [tex]\pi( \frac{9}{2} )^{2} =(3.14)(4.5)^{2} = 63.585[/tex] square cm
Therefore,
The difference between the areas of two circles = (113.04 -63.585) square centimeter = 49.455 square centimeter.
