mark is 26=x and marissa id 33
if you take 59 take away 7 you get 52
then you wil devide 52 and get 26
you will use the 7 you took out earlier and add it to one of the 26 which will give you mark(26=x) and marissas(33) age .

Solve using proportions.
The triangles are similar, find the length of side (k) using a proportion; having ratios within the two figures.
Note: If someone could please answer before this upcoming Monday.
Answer:
7.8 = k
Step-by-step explanation:
Since the figures are similar, we can use proportions
c k
----- = -------
b j
Substituting the values in
6.5 k
----- = -------
4 4.8
Using cross products
6.5 * 4.8 = 4k
31.2 = 4k
Divide each side by 4
31.2/4 = 4k/4
7.8 = k

Finding missing angles
please help!! i’m literally begging
Answer:
65
Step-by-step explanation:
the square means 90 add that to 25 and subtract from 180
Answer:
x = 65
Step-by-step explanation:
The measure of the entire angle is 180°. The angle on the furthest left (with a square in it) is a right angle, meaning that it is 90°.
All three of the angles (90°, x°, 25°) all add up to the measure of the line, which is 180°. So, we can write this equation.
90 + x + 25 = 180
Subtract 90 and 25 from both sides.
90 + x + 25 - 90 - 25 = 180 - 90 - 25
x = 65
Solve the equation using square roots
x^2 - 55 = 26
Answer:
x = ±9
Step-by-step explanation:
x² - 55 = 26
+55 + 55
x² = 81
x = √81
x = ± 9
Answer:
x = 9, -9
Step-by-step explanation:
x^2 - 55 = 26
x^2 = 81.
Now, you might think that x = 9, but don't be fooled. -9 squared is also equal to 81.
So, x = 9, -9

Write a quadratic function in vertex form whose graph has the vertex ( -5. - 1) and passes through the point (-2.2).
Answer:
[tex](\frac{1}{3})(x+5)^2-1[/tex]
Step-by-step explanation:
So first let's write a graph in vertex form with a vertex of (-5, -1)
We get
a(x+5)²-1
We now need to determine a
we know that when x= -2 y=2 which means we have
a(-2+5)²-1=2
Solve for a
a(3)²=3
9a=3
a=3/9
a=1/3
Now that we know what a is equal to we can write our equation
[tex](\frac{1}{3})(x+5)^2-1[/tex]

Answer: n=7+1/2
Step-by-step explanation:
We move all terms to the left:
2n+15-(30)=0
We add all the numbers together, and all the variables
2n-15=0
We move all terms containing n to the left, all other terms to the right
2n=15
n=15/2
n=7+1/2

Given X is midpoint of RS , MX =XS Prove Mx =RX
Answer:
Transitive Property
Step-by-step explanation:
Since X is the midpoint, it bisects the points RS. If MX=XS, and RS is the same as XS, then they are the same. This also follows the Transitive propety (if a=b and b=c, then a=c)

what is 4x+3x-12+1x
Answer:
8x-12
Hope it helped plz mark me brainliest PlzPlz
Answer:
8x-12
Step-by-step explanation:
You need to find a number/numbers that have the same variable if the variable is the same then you can add or subtract them
You can add 4x, 3x and 1x
4x plus 3x plus 1x is 8x
Since -12 is alone you can leave it as it is
8x-12

The height of a male athlete testing his vertical jump can be modeled by h = − 16t ^2 + 14t. The height is h and the time is t. How many seconds is he in the air?
Answer:
0.88 (I think this is how Mrs. Futch wants it to be written)
Step-by-step explanation:
h=-16t^2+14t
(Substitute h with 0)
0=-16t^2+14t
(Factor)
0=2t(-8t+7)
2t=0 -8t+7=0
t=0 t=0.88
{0, 0.88}
Answer:
So everyone here in Mrs. Futch?

A bag contains 40 red and green marbles. The number of green marbles, g, is 9 times the number of red mapples, . How many red marbles are in the bag? O 4 O 6 O 34 O 36
Answer:
4
Step-by-step explanation:
You need to try out all the numbers.
lets start with 4
if there where 4 red marbles then there would be 9 times as many marbles
so 4 x 9 = 36
Now we add and see if the sum is 40
36 + 4 = 40
We got it on the first try
You can use the same method on more problems like these.
Hope this helps :)
what are major turning points in algebraic knowledge through out history
Answer:
There are a lot of turning point in the history of algebra one of those is the discovery of the plain and the quadrants by Rene Descartes. This discovery paved way to a lot of knowledge which was later on use in solving other complicated mathematical problems.
Step-by-step explanation:
Which of the following equations is equivalent to 3 • 12 = 36?
36 + 3 = 12
36 ÷ 3 = 12
36 • 3 = 12
36 – 3 = 12
Answer:
B
Step-by-step explanation:
36 ÷ 3 = 12 is basically the division version of the original equation. None of the other equations equal the same answer so B is the correct option.
36 ÷ 3 = 12 is equivalent to 3 • 12 = 36
