Logan is 2 years older than Lindsey. Five years ago, the sum of their ages was 30. Find Lindsey’s
current age.
Answer:
lindsey = x = 19
logan = x + 2 = 21
Step-by-step explanation:
lindsey =x
logan = x + 2
-------
5 yrs back
lindsey = x - 5
logan = x + 2 - 5 = x - 3
~~~~~~~~~~
x- 5 + x - 3 = 30
x + x - = 30 +5 +3
2x = 38
x = 38/ 2 = 19

Solve each problem. Round to the nearest tenth if necessary. Use 3.14 for π. What is the radius of a circle with a circumference of 15 cm? Show your work! I will be giving out brainliest!
Answer:
2.3
Step-by-step explanation:
First off, you start with the circumference formula which is 2(pi)r. Since we know our circumference, we can create the equation solving for r. so we have 15=2(pi)r. Now in order to solve for r, we need to transfer everything to the other side, meaning dividing by 2(pi). So 15/2(pi)=2(pi)r/2(pi). Since we are using 3.14 for pi, 3.14*2 is 6.28. 15/6.28 which is about 2.388 So the radius of the circle is 2.3 (rounded to the nearest tenth)
solve for x
(5x+6)(6x-25)=180
Step-by-step explanation:
5x+6+6x-25=180
We move all terms to the left:
5x+6+6x-25-(180)=0
We add all the numbers together, and all the variables
11x-199=0
We move all terms containing x to the left, all other terms to the right
11x=199
x=199/11
x=18+1/11

Answer:
f(x) = 3x² - 14x - 5
Step-by-step explanation:
multiply the factors: (x + 1/3)(x - 5)
x² - 5x + 1/3x - 5/3
x² -14/3x - 5/3
multiply by 3 to eliminate fractions:
3x² - 14x - 5

What is the solution
-3x + y = 2
y = x + 4
Answer:
to find the solution, we substitute y = x + 4 into the other equation.
-3x + (x + 4) = 2
-3x + x + 4 = 2
-2x = 2 - 4
-2x = -2
x = 1
to find y, we substitute x to the x variable in the y equation.
y = 1 + 4
y = 5
therefore, when combined, it is (1,5).
A circle has circumference 33.9 cm. What is the area of the circle? Use 3.14 for .
The area of the circle is about cm?
(Round the final answer to the nearest whole number as needed. Round all intermediate values to the nearest thousandth as needed.)
Answer:
The area is 902[tex]cm^{2}[/tex]
Step-by-step explanation:
[tex](\frac{33.9}{2})^{2}[/tex] * 3.14
= [tex]16.95^{2}[/tex] * 3.14

A quadratic equation has a
discriminant equal to 5. What
does this tell you about the
solution(s) to the equation?
Answer:
[tex]\boxed {\boxed {\sf 2 \ real \ solutions }}[/tex]
Step-by-step explanation:
The quadratic formula is:
[tex]{x = \frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}}[/tex]
The discriminant of a quadratic is just the expression under the square root, or [tex]b^2-4ac[/tex]. This can tell us the number of solutions a quadratic has.
If the discriminant is:
Positive = 2 real solutions Equal to Zero = 1 real double/repeated solution Negative = 0 real solutions, but 2 imaginary solutionsOur quadratic equation has a discriminant of 5, which is positive. Therefore, it has 2 real solutions.

Need to find measure of m, p
Step-by-step explanation:
2p-5=p+5
p=10°
2m=10
m=5
Answer:
m = 5
p = 10
Step-by-step explanation:
In triangle HIJ,
IH = IJ.. (given)
Therefore,
2m = 10
m = 10/2
m = 5
IK is angle bisector of triangle HIJ.
So,
(2p - 5)° = (p = 5)°
2p - 5 = p + 5
2p - p = 5 + 5
p = 10
Find slope of a line using points (2,0) and (4,3)
for every 5 red cars there are 8 black cars. If there are 24 more black cars than red cars how many total vehicles are there
Answer:
15 red cars + 24 black cars = 38
The total vehicles are 104.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
For every 5 red cars there are 8 black cars.
And, There are 24 more black cars than red cars.
Here, For every 5 red cars there are 8 black cars.
Hence, Number of red cars = 5x
Then, Number of red cars = 8x
And, There are 24 more black cars than red cars.
Hence, We get;
⇒ 24 + 5x = 8x
Solve for x as;
⇒ 24 = 8x - 5x
⇒ 24 = 3x
⇒ x = 8
Thus, Number of total vehicles = 5x + 8x
= 5×8 + 8×8
= 40 + 64
= 104
