Solve the system of linear equations.
13x+y=1
2x+6y=6
Answer:
x = 0 and y = 1 Solution: (0, 1)
Step-by-step explanation:
13x + y = 1 multiply by -6 ⇔ -78x - 6y = -6
2x + 6y = 6 do not change ⇔ + 2x + 6y = 6
-76x = 0
x = 0
Use the second equation to solve for y if x = 0
2x + 6y = 6
2(0) + 6y = 6
0 + 6y = 6
6y = 6
y = 1 Solution (0,1)

Answer:
x+ 3/2y= 15
Step-by-step explanation:
8x+12y=120
To put the equation into standard form, the leading coefficient has to be 1. So, divide the whole equation by 8.
x+ 3/2y= 15

5/6+3/4+2/3 answer please
Answer:
2.25
Explanation
2/3 can be made into 4/6 then added to 5/6
Grab 5/6 and add it to 3/4, we do this by making them have the same bottom number (denominator) so we multiply 9/6 (4/6 + 5/6) by 2 (both top and bottom number) so now we have 18/12 + 4/6 so now we can make 4 be 12 by multiplying it by 3, but we need to do that to the top number as well to make it balanced, so now we have 18/12 + 9/12 and we get 27/12 or 2.25.

Mr. Jones bought a piece of land for 60 000. The land increased in value by 20% in a year. The new value of the land is
Answer:
$72,000
Step-by-step explanation:
If we take 60,000 and then take 20 percent of it, we get 12,000. Then we add 12,000 to 60,000 and it gives us 72,000.

HELP ME WITH THIS TWO PROBLEMS
1. When I add 6 to five times my number I get 36. My mystery number is ....
2. When I add 7 to three times my number I get 43. My mystery number is....
Answer:
1) 6 & 2)12
Step-by-step explanation:
Solve the equations backwards-
1) Subtract 6 from 36, and then divide by 5.
36 = 6 + 5x
(36 - 6)/5 = x
x = 6
2) Subtract 7 from 43, and then divide by 3.
43 = 7 + 3y
(43 - 7)/3 = y
y = 12

Which expression below shows that 98 can be written as the product of prime numbers?
A 2 × 49
B 7 × 7 × 2
C 5 × 5 × 2
D 14 × 7
Answer:
Step-by-step explanation:
Option A
(-2)(-49)
=2×49
=98
Option B
(4)(-27)
=-108
Option C
(-7)(14)
=-98
Option D
(-9)(11)
=-99. As a result, there us only one correct option that equal -98 which is Option C. Hope it help!

1, a.) The two specific conjectures are in the first image.
1, b.) The two general conjectures are in the second image.
2, a.) Two specific conjectures for this pattern are:
The common difference between two consecutive terms is 3.And the given difference is A.P.2, b.) From our observation two general conjecture is that the given sequence is an arithmetic sequence and the common difference is 3.
For finding its nth term we can use the formula: a(n) = a + (n-1) x d.
2, c.) A formula for the given pattern is 5 + (n-1)3, where n is the number of the term.

Please solve the equation below.
2x+4=3(x-4)
Answer:
x=16Step-by-step explanation:
[tex]\sf 2x+4=3(x-4)[/tex]
[tex]\sf 2x+4=3x-12[/tex]
[tex]\sf 2x+4-4=3x-12-4[/tex]
[tex]\sf 2x=3x-16[/tex]
[tex]\sf 2x-3x=3x-16-3x[/tex]
[tex]\sf -x=-16[/tex]
[tex]\sf \cfrac{-x}{-1}=\cfrac{-16}{-1}[/tex]
[tex]\sf x=16[/tex]
solve the equation below :-
2x+4=3(x-4)
Answer:-x = 16
Explanation:-=> 2x+4 = 3(x-4)
=> 2x+4 = 3x-12
=> 2x+4 - 4 = 3x-12 - 4 (Subtract 4 on both the sides)
=> 2x = 3x-16
=> 2x-3x = -16
=> -x = -16
=> -x/-1 = -16/-1
=> x = 16
Marco is five years less then twice hi sister Leah's age. Their mother is 14 years older than Marco and Leah's combined ages. If their mother is 48 years old, how old is Marco?
Answer:
Marco is 21
Step-by-step explanation:
Let the sister's age = x
Marco's age = 2*x - 5
x + 2x - 5 + 14 = 48 Combine the left side of the equation.
3x + 9 = 48 Subtract 9 from both sides
3x = 48 - 9
3x = 39 Divide by 3
x = 39/3
x = 13
So the sister is 13
Marco = 2x - 5 = 2*13 - 5
Marco = 21
