What is the solution to this system of equations? 5x + 2y= 29
x + 4y = 13
A x = 5, y = 3
B. x=2, y=5
C. X= 5, y = 2
D. x= 3, y = 2
Answer:
C
Step-by-step explanation:
Given the 2 equations
5x + 2y = 29 → (1)
x + 4y = 13 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate the y- term
- 10x - 4y = - 58 → (3)
Add (2) and (3) term by term to eliminate y
- 9x + 0 = - 45
- 9x = - 45 ( divide both sides by - 9 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (2)
5 + 4y = 13 ( subtract 5 from both sides )
4y = 8 ( divide both sides by 4 )
y = 2
Solution is x = 5, y = 2 → C
Answer:
c) x = 5, y = 2
Step-by-step explanation:

Jill orders t-shirts on Amazon. Each shirt costs $15.00 including tax. A one-time shipping fee of $3.25 is added to the cost of the order. The total cost of Jill's order is $78.25. How many t-shirts did Jill order? *
Answer:
5 shirts
Step-by-step explanation:
Step one:
given data
Each shirt costs $15.00 including tax.
A one-time shipping fee of $3.25
The total cost of Jill's order is $78.25
Step two:
let the number of shirts be x
so
y=15x+3.25
for y= $78.25, let us find x
78.25=15x+3..25
collect like terms
75= 15x
divide both sides by 15
x=75/15
x=5

C. −53
D. 53
9514 1404 393
Answer:
A. 3/13
Step-by-step explanation:
The slope formula is ...
m = (y2 -y1)/(x2 -x1)
Using the given points, this is ...
m = (-4 -(-1))/(-8 -5) = -3/-13 = 3/13
The last one is y-2=-(x-4) sorry I couldn’t fit it all in
Answer:
y + 2 = (x - 2)
Step-by-step explanation:
From the graph, you can see that when y = 0, x = 2, and vise versa. Taking this into consideration, if y = 4, x = 2, so, the answer is y + 2 = (x - 2)

Rhion sat maths and English test
In the maths she scores 14 out of 17
In th english test she scored 31 out of 39
which one did she do better.
Answer:
Rhion did better in maths test.
Step-by-step explanation:
Given that:
Rhion scored 14 out of 17.
We will find percentage and then compare them.
Percentage = [tex]\frac{Score}{Total\ marks}*100[/tex]
Percentage = [tex]\frac{14}{17}*100[/tex]
Percentage = 82.35%
Rhion scored 31 out of 39.
Percentage = [tex]\frac{31}{39}*100[/tex]
Percentage = 79.48
On comparing,
82.35 > 79.48
Hence,
Rhion did better in maths test.

What is 15 times 2/3
Answer:10
Step-by-s First of all, note that 15 is the same as 15/1 since 15 divided by 1 is 15. Therefore, start by setting up the problem like this
Step 2: Multiply
Multiply the numerators together (15 x 2 = 30) and multiply the denominators together (1 x 3 = 3) and make it into one fraction like so:
Step 3: Minimize
The greatest common factor of 30 and 3 is 3. Minimize the fraction by dividing the numerator and the denominator by its greatest common factor to get:
Step 4: Convert
Convert the improper fraction above to a whole number to get the answer:
That's it! Now you know how to calculate 15 times 2/3.

Answer:
-2 tiles
Step-by-step explanation:
In each figure, 5 tiles are added.
Subtract 5 from how many tiles are in Figure 2 (8 tiles) & you get 3.
3 is how many tiles are in Figure 1, meaning you need to subtract 5 again to see how many are in Figure 0! 3-5 = -2.
Hope this helps! x

The surface area of each face of a cube is (x
2 + 6x + 9) m2
Find an expression for the,
i. length of each edge
Answer:
length of each edge = (x + 3)
Step-by-step explanation:
The surface area of each face of the cube = ([tex]x^{2}[/tex] + 6x + 9) [tex]m^{2}[/tex]. But the surface of a cube has the shape of a square. So that,
Area of a square = length x length
= [tex]l^{2}[/tex]
By factorizing the area,
[tex]x^{2}[/tex] + 6x + 9 = [tex]x^{2}[/tex] + 3x + 3x + 9
= ([tex]x^{2}[/tex] + 3x) (3x + 9)
= x(x +3) + 3(x + 3)
= (x + 3)(x + 3)
= [tex](x + 3)^{2}[/tex]
[tex]x^{2}[/tex] + 6x + 9 = [tex](x + 3)^{2}[/tex]
Thus,
[tex](x + 3)^{2}[/tex] = [tex]l^{2}[/tex]
find the square root of both sides
l = (x + 3)
length of each edge = (x + 3)
