Let as consider, we need to find the number of hours h it will take Mandy to catch up with Rita.
Given:
The number of hours h it will take Mandy to catch up with Rita is represented by the equation
[tex]2.5h+1=3h+2[/tex]
To find:
The value of h.
Solution:
We have,
[tex]2.5h+1=3h+2[/tex]
Isolate the variable terms on one side.
[tex]2.5h-3h=-1+2[/tex]
[tex]-0.5h=1[/tex]
Divide both sides by -0.5.
[tex]h=\dfrac{1}{-0.5}[/tex]
[tex]h=-2[/tex]
We know that, time cannot be negative. So, [tex]h\neq -2[/tex].
The equation [tex]2.5h+1=3h+2[/tex] is not true for any positive value of h.
Therefore, Mandy will never catch up with Rita.
Hanna says you cannot represent the fraction 1/4 on the number line.
Answer:
The answer is D; Hanna is not correct,. The fraction 1/4 is equal to 2/8, so you can graph it on the second tick mark to the right of zero.
Step-by-step explanation:
Because the number line is broken up into 8 parts, the points on the graph are, 1/8, 2/8, 3/8, 4/8, 5/8, 6/8, 7/8, 8/8 (also known as one)
1/4 = 2/8. We know this because if we multiply 1/4 by 2, we get 2/8.
So, because 2/8 is the same as 1/4, we know that Hanna is not correct, and that you can graph 1/4 on this number line, because it is the same as 2/8.
I hope that this helps :)

Jerome found the lengths of each side of triangle QRS as shown, but did not simplify his answers. Simplify the lengths of each side to answer the question. Which statement about triangle QRS is true?
a. Triangle QRS is an equilateral triangle because QR = RS.
b. Triangle QRS is an isosceles triangle because QR = QS.
c. Triangle QRS is a scalene triangle because all sides have different lengths.
d. Triangle QRS is an isosceles triangle because QR = RS.
Answer:
D. Triangle QRS is an isosceles triangle because QR = RS.
Step-by-step explanation:
Find the length of each side of the triangle using the formula for calculating the distance between two points.
D = √(x2-x1)²+(y2-y1)²
For side RS
R(0,0) and S(5, -3.322)
RS = √(5-0)²+(-3.322-0)²
RS = √25+11.035684
RS = √36.035684
RS = 6.0029
For side RQ
R(0,0) and Q(-3, -5.2)
RQ = √(-3-0)²+(-5.2-0)²
RQ = √9+27.04
RQ = √36.04
RQ = 6.0033
For side QS
Q(-3,-5.2) and S(5, -3.322)
QS = √(5+3)²+(-3.322+5.2)²
QS = √64+3.526884
QS = √67.526884
QS = 8.22
From the calculation it can be seen that RS=QR
Since the two sides f the triangle are equal, hence the triangle is an isosceles triangle. An isosceles triangle is a triangle that has two of its sides equal

Solve the system of equations..
y = 8x - 6
y= 5x +9
Answer:
x = 5
y = 34
Step-by-step explanation:
Sub y = 8x - 6 into second equation (y = 5x + 9)
8x - 6 = 5x + 9
Rearrange by collecting like terms
8x - 5x = 9 + 6
3x = 15
x = 5
Sub x = 5 into first equation (y = 8x - 6)
y = (8*5) - 6
y = 40 - 6
y = 34

The Y- intercept form from the line whose slope is 2 and passes through (-7,11)
Answer:
y = 2x + 25
Step-by-step explanation:
Slope-Intercept Form: y = mx+b
Slope: m = 2
y = 2x + b
Solve for b:
y = 2x + b
11 = 2(-7) + b
11 = -14 + b
b = 25
y = 2x + 25

Answer:
p = 45 - 2.5f
Step-by-step explanation:
5f + 2p = 90
just manipulate the equation, treat it like a regular algebra equation and solve for p by inverse operations and simplifying
5f + 2p = 90
-5f -5f
2p = 90 - 5f
/2 /2
p = [tex]\frac{90 -5f}{2}[/tex]

Can you hellllp me pleaaaseeee
Answer:
Total interest = A - P = $2,223.00
Total amount = $10,023.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 9.5%/100 = 0.095 per year.
Solving our equation:
A = 7800(1 + (0.095 × 3)) = 10023
A = $10,023.00
The total amount accrued, principal plus interest, from simple interest on a principal of $7,800.00 at a rate of 9.5% per year for 3 years is $10,023.00.

Step-by-step explanation:
the way to figure out a cale factor is to divide a new side by an old side, in this case you could divide 24 by 15 to get 1.6
multiply the side congruent to x by 1.6, so 25 and 1.6
you should get 40
