Find x and y please!! I’m desperate!!!
Answer:
x = 4
y = 2
Step-by-step explanation:
the third angle of the triangle
180 - (148 + 18) = 14º
Therefor
3x + y = 14
5x - y = 18
Add the equations
8x = 32
Divide both sides by 8
x = 4
Plug in x = 4
3(4) + y = 14
12 + y = 14
y = 2
9514 1404 393
Answer:
(x, y) = (4, 2)
Step-by-step explanation:
The triangles are similar by AA similarity, so the corresponding angles are congruent.
5x -y = 18 . . . . . . unmarked angles are congruent
18 +(3x+y) +148 = 180 . . . . . sum of angles in a triangle is 180°
__
After subtracting 166 from both sides, the second equation simplifies to ...
3x +y = 14
Adding this to the first equation gives ...
8x = 32
x = 4 . . . . . . divide by 8
Then substituting for x in the first equation gives ...
5(4) -y = 18
20 -18 = y = 2
The values of the variables are x = 4, y = 2.

The angle marked with a double mark is 14°, given by the simplified second equation.
Help! What can we do to kill off the zombies?? The scientists realize that salt kills the zombies, if enough is poured on them (one full can). The reaction between the salt and zombie blood causes the zombie to disintegrate. Morton's salt has a plant in Tooele county just west of Grantsville, and can distribute cans of salt to people residing in Utah. If Morton's salt can distribute 300,000 cans of salt each day, write an equation to model the number of cans of salt distributed after n days.

Maria started her savings account with $105. she adds $10 to it each month, including the first month. Jana Rae started her account with $0 she adds $25 to it each month. after how many months will the girls have the same amount in their accounts? how much will they have?
Answer:
After 7 months, the girls will have the same amount in their accounts. They will have 175.
Step-by-step explanation:
Maria:
Starts with $105
Adds $10 each month
Jana Rae:
Starts with $0
Adds $25 each month
Set up an equation for both Maria and Jana.
m will represent the number of months.
Maria: 105 + 10m
Jana: 0 + 25m
You can do guess and check.
Let’s say m is equal to 6.
Subsitute m with 6 for both equations and check if they both end up having the same answer.
Maria: 105 + 10(6) = 165
Jana: 0 + 25(6) = 150
Is 165 and 150 equivalent? No
Let’s try m = 7 and do that same thing.
Maria: 105 + 10(7) = 175
Jana: 0 + 25(7) = 175
Now is the answer equal? Yes
So therefore, after 7 months, the girls will have the same amount in their accounts. They will have 175.

What is the midpoint of the line segment whose
endpoints (7,-4) and (-3, -2)?
are
Answer: (2, -3)
Step-by-step explanation:
To find the the answer, you will need to use the midpoint formula, which is as following:
(x₁+x₂/2, y₁+y₂/2)
Since we have two coordinates, let's substitute them into the equation.
(7 + (-3 )/ 2, (-4) + (-2)/2)
We should first add 7 and -3 together, as well as -4 and -2.
(4/2, -6/2)
We then divide 4 and -6 by 2. This would give us our midpoint coordinate.
(2, -3)

Dilation is something expanding or shrinking, like how your eyes dilate.
Simply think of the scale factor as what you are multiplying the entire figure by. If you are multiplying it by let's say 2, it would double in size, thus getting larger. If you were to multiply it by 1/2, then it would decrease, or shrink, to half its original size.

Tiffany is filling her daughter's pool with water from a hose. She can fill the pool at a rate of 1/10 gallons per second.
Create at least three equivalent ratios that are associated with the rate. Use a double number line to show your work.
The three equivalent ratios are 6/1 gallons/minute, 1/40 quarts/second and 360/1 gallons/hour.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given that, Tiffany can fill the pool at a rate of 1/10 gallons per second.
Equivalent ratios are the ratios that are the same when we compare them.
We know that, 60 seconds =1 minute
1/10 × 60 = 6 gallons/minute
1 gallon = 4 quarts
1/10 = 1/10×4 = 1/40 quarts/second
1 hour =60 minute
So, 6 gallons/minute =6×60
= 360 gallons/hour
Here, 6 gallons/minute = 1/40 quarts/second = 360 gallons/hour
Therefore, the three equivalent ratios are 6/1 gallons/minute, 1/40 quarts/second and 360/1 gallons/hour.

Hello. . .
I need help please. . .
answers/w explanation. ✅
Nonsense answers, or answers that's not the question I ask for will be reported.
Answer:
x = 1 , y = 4
Step-by-step explanation:
I am assuming you're looking for what x and y are? If so, then we know that
DC and AB equal each other, so
4x + y = 8
CB and AD equal each other, so
2x + y = 6
We have two equations that cannot be solved on their own, so we must solve them as a system of equations. One process to solve is elimination.
4x + y = 8
2x + y = 6
we can multiply the second equation all by -1 to make the y's cancel out and give us x. so,
4x + y = 8
-1(2x + y) = 6
4x + y = 8
-2x -y = -6
now solve them vertically. we get:
2x = 2
and so x = 1.
Now that we found x, we must find y. Using any of the two equations froom above, we can substitue our x value of 1 into it to find y. I will use the first one.
4x + y = 8
4(1) + y = 8
4 + y = 8
y = 8 - 4
y = 4
so our x is 1 and y is 4.
hope this helps! (:

What is 4 times 1 6/7. Write in the simplest form
Answer:
7 43/100
Step-by-step explanation:
4*1 6/7=4 24/7 which equals 7.43, or 7 43/100
Answer:
7 3/7
Step-by-step explanation:
4 * 1 6/7
1 = 7/7, so 1 6/7 = 7/7 + 6/7 = 13/7
4 * 13/7 = 52/7
7 can fit into 52 at most 7 times (because 7*7 is 49, and less than 52)
This leaves us with 3 left over
4 * 1 6/7 = 7 3/7

Musi measured the length and width of a soccer field and then made a drawing of the soccer field . He decided to use 1 mm on his ruler to represent 3 m on the soccer field. If his measurement of the width of the soccer field was 63m , what is the width of his drwaing?
If his measurement of the width of the soccer field was 63m , the width of Musi's drawing for a 63 m wide soccer field is 21 mm.
Musi's ruler represents 1 mm as 3 m on the soccer field. To find the width of his drawing for a 63 m wide soccer field, we can set up a proportion to relate the real width to the width on his drawing.
Let "x" represent the width of his drawing in millimeters.
The proportion can be set up as follows:
1 mm (on the drawing) / x mm (real width on the field) = 3 m (on the drawing) / 63 m (real width on the field)
Now, cross-multiply and solve for "x":
1 * 63 m = 3 * x mm
63 = 3x
Divide both sides by 3 to find the width of his drawing:
x = 63 / 3
x = 21
So, the width of Musi's drawing for a 63 m wide soccer field is 21 mm.
In summary, Musi used a scale of 1 mm to represent 3 m on the soccer field. Therefore, the width of his drawing for a 63 m wide soccer field is 21 mm.
