Answer:
y=3-x
Step-by-step explanation:
Answer:
First we get y on one side by itself.
5x+5y=15
We move x over to the other side.
5x-5x+5y=15-5x
Simplify.
5y=15-5x
Now we remove the coefficient from y.
5y/5=(15-5x)/5
Simplify.
y=15/5-5x/5
y=3-x
The answer is y=3-x

Step-by-step explanation:
Cynthia Besch wants to buy a rug for a room that is 24 ft wide and 32 ft long. She wants to leave a uniform strip of floor around the rug. She can afford to buy 560 square feet of carpeting. What dimensions should the rug have?
Answer:
[tex]D=(20.42)(28.42)[/tex]
Step-by-step explanation:
From the question we are told that
Width [tex]W=24ft[/tex]
Length [tex]L=32ft[/tex]
She can afford to buy 560 square feet of carpeting
Let
[tex]S=width\ of\ strip[/tex]
Generally the Dimension of the rug is mathematically given as
Width of Rug [tex]W' = (24- 2S)ft[/tex]
Length of Rug [tex]L'= (32-2S) ft[/tex]
Generally the width of strip S is mathematically given by
[tex](32-2s)*(24-2s)=560[/tex]
[tex]-4s-112s+208=0[/tex]
[tex]s_1=-29.7\\s_2=1.748[/tex]
Therefore the width is
[tex]s=1.748[/tex]
Generally the dimension of the rug D is mathematically given as
Width of Rug [tex]W' = (24- 2s)ft[/tex]
[tex]W' = (24- 2(1.79))ft[/tex]
[tex]W' =20.42ft[/tex]
Length of Rug [tex]L'= (32-2S) ft[/tex]
[tex]L'= (32-2(1.79)) ft[/tex]
[tex]L'=28.42 ft[/tex]
Therefore dimension of Rug is given by
[tex]D=(20.42)(28.42)[/tex]

2 questions correct anwser gets brainlyess
Answer:
Question 1: x=55Question 2: m∠A=45°Step-by-step explanation:
Question #1
- Since it is an isosceles triangle, this means that the base angles have the same value.
- The angle sum is 180°
Solve
2x+35+35=180
2x+70=180
2x=110
x=55
Question #2
- Since it is given there is a right angle, this means the angle is 90°
- The angle sum is 180°
Solve
5x+5x+90=180
10x+90=180
10x=90
x=9
It asked to find m∠A, which is 5x. So 5x=5(9)=45°
Hope this helps!! :)

Hi if u could help me that'd be great
Answer:
1 hour and 45 minutes
and 1 hour
Step-by-step explanation:
x= run
y= walk
5x+2.5y = distance
5x+2.5(1.5)=12.5
solve for x
5x=8.75
x=1.75
1.75 in hours is 1 hour and (60*.75)=45
1 hour and 45 minutes
" If the marathon race participant ran for 2 hours, how many hours did the participant walk?"
We use the same equation
5x+2.5y=distance
we'll assume that they till walked 12.5 miles
which means that
5(2)+2.5y=12.5
solve for y
2.5=2.5y
y=1
1 hour

Answer:
the area of the shape is 24
Step-by-step explanation:
Solve the triangle.
B = 36°, a = 38, c = 18
b ≈ 41.7, C ≈ 28.2, A ≈ 115.8
b ≈ 25.7, C ≈ 24.2, A ≈ 119.8
b ≈ 25.7, C ≈ 116.8, A ≈ 27.2
b ≈ 41.7, C ≈ 24.2, A ≈ 119.8
Answer:
b ≈ 25.7, C ≈ 24.2, A ≈ 119.8
Step-by-step explanation:
b² = a² + c² - 2ac·cos(B)
b² = 38² + 18² -2·38·18·cos(36°) ≈ 661.26475
b ≈ 25.715
sin(C)/c = sin(B)/b
C = arcsin(c/b·sin(B)) ≈ 24.29515°
∠A can be found as 180° - ∠B - ∠C
A = arcsin(a/b·sin(B)) ≈ 119.70485°

Using the math from 7th grade, 6 rooted is 36/9=4+10 is 14. Everything else you must multiply everything in parenthesis, by the outside number, then you add them. E is right because -15+35=20-6=14. Yw.
help me pls , im stupif
It's alright, you're not stupif. It's just a little bit complicated if it's either your first time doing it or has been a while since you did it last.
r: 16 km. d: 32 km.
The Formula is: C = 2πr. Because it says below the rest of the data that we use 3 for pi, and since we have r, which is 16, the equation becomes C = 2(3)(16).
The answer becomes 96 Kilometers.

40
Step-by-step explanation:
16 + (4+12) = 32 + 8 = 40
Find the missing length
Answer: 15
Step-by-step explanation:
For this you will have to use pythagoras’ theorem.
The formula for the shorter side of this triangle is u²=c²-b² (or in this case u²=17²-8²).
17²=289
8²=64
The formula becomes u²=289-64 or u²=225
Then to find u on its own you have to square root 225.
The square root of 225 is 15.
