y=2+3x
putting value on second equation we get..
x-2(2+3x)=-6
x-4+6x=-6
7x=-2
×=-2/7
& y=2+3(2/7)
y=2+0.87
y=2.87..Ans..
Answer:
x= 2/5
y= 3.2
Step-by-step explanation:
y-3x=2
y=3x+2
replace y with 3x+2 in second equation;
x-2(3x+2)= -6
x- (6x+4)= -6
x-6x-4= -6
-5x-4+4=-6+4
-5x= -2
x= 2/5
y=3x+2
y=(3×2/5) +2
y= 3.2
The sum of Mrs. son's age and her age was 70 two years ago Q's age was 5 less than twice her son's age . Write a system and solve to find their ages
Step 1: Set up a table.
Algebra Age Problems
Step 2: Fill in the table with information given in the question.
John is twice as old as his friend Peter. Peter is 5 years older than Alice. In 5 years, John will be three times as old as Alice. How old is Peter now?
Let x be Peter’s age now. Add 5 to get the ages in 5 yrs.
Algebra Age Problems
Write the new relationship in an equation using the ages in 5 yrs.
In 5 years, John will be three times as old as Alice.
2x + 5 = 3(x – 5 + 5)
2x + 5 = 3x
Isolate variable x
x = 5
Answer: Peter is now 5 years old.

what percent of 82 is 9.75. Round your answer to the nearest tenth
Hi there!
8 would be the nearest ten of 7.995..
1.Multiply 82 with 0.01:
[tex]82[/tex]·[tex]0.01=0.82[/tex]
2.Multiply the terms:
[tex]0.82[/tex]·[tex]9.75=7.995[/tex]
3.Round the term:
[tex]7.995=8[/tex]
Therefore, 82% of 9.75 in nearest tenth is 8.

Paul built a triangular garden in his backyard, which is enclosed by a rectangular fence. How much of the backyard is not covered by the garden
Answer: 476m²
Step-by-step explanation:
Find the area of the triangle and then subtract it from the area of the rectangle.
Area of triangle = 1/2 * base * height
= 1/2 * 8 * 6
= 24m²
Area of rectangle:
= Length * Width
= 25 * 20
= 500m²
Area not covered by garden:
= 500 - 24
= 476m²
Can someone help please
Answer:
50
Step-by-step explanation:
20+20=40
5+5=10
40+10=50
Answer: P=50
Step-by-step explanation: 20 m = length and 5 m = width
Solution:
P=2(l+w)=2·(20+5)=50
So the perimeter is 50

What is m
Enter your answer in the box
Answer:
m = 2
Step-by-step explanation:
∠ GLI = 90°
∠ GLH + ∠ HLI = ∠ GLI , that is
9m + 25m + 22 = 90
34m + 22 = 90 ( subtract 22 from both sides )
34m = 68 ( divide both sides by 34 )
m = 2
Then
∠ HLG = 9m = 9 × 2 = 18°

round 34 1/8 to the nearst whole number
Answer:
34
Step-by-step explanation:
Because it is a mixed fraction, it tells us the whole number already. After that, we need to look at the actual fraction part and decide if it's large enough to round the whole number up. 1/8 is not, so we keep the whole number at 34
Answer:
That would be 34

24 m^2
Step-by-step explanation:
We need to study the structure well
We can find the magnitude of the big rectangle. We will need to find the total length and total breadth of the big rectangle
Then we remove the area of the four squared cut out from the big rectangle.
Total length of the rectangle is 5+1+1=7m
Then the length of the breath of the rectangle is 2+1+1=4m
So area of rectangle is given as length × breadth
Area= l×b
Area=7×4=28m²
Area of the big rectangle is 28m²
Then the squared is made of dimension 1m by 1m
Area of a square is s²
Then, a=1m
Area of the square= 1²=1m²
There are four squared side
Then, the total area of the four squared is 4×1=4m²
Then the required area is
Area=Total area - area of four squared side
Area=28m²-4m²
Area =24m²
Area of the figure is 24m²
The correct option is A.

Answer: 15 √ 2
Step-by-step explanation:
Equilateral triangles have three equal side lengths, three equal angles of 60 degrees, and three equal altitudes.
You would think that the height of an equilateral triangle would also be equal to it's sides, but it's not. The formula for height is: side/2 x √3
10√6 / 2 * √ 3 = 15 √ 2
The decimal form: 21.2
