Answer:
(1, 2 )
Step-by-step explanation:
x + y = 3 (subtract x from both sides )
y = 3 - x → (1)
2x - y = 0 → (2)
Substitute y = 3 - x into (2)
2x - (3 - x) = 0
2x - 3 + x = 0
3x - 3 = 0 ( add 3 to both sides )
3x = 3 ( divide both sides by 3 )
x = 1
Substitute x = 1 into (1)
y = 3 - 1 = 2
solution is (1, 2 )
7x-12y=180 7x=84
i need someone to explain step by step
Answer:
x=12,y=-8
Step-by-step explanation:
7x=84
x=84/7=12
12y=7x-180=7*12-180=84-180=-96
y=-96/12=-8
The solution of 7x-12y=180 is x = 12 and y =-8.
What is an equation?An equation is made up of two algebraic expressions with the same value and the sign "=" in between.
Given, the equation;
7x-12y=180 {equation 1}
And 7x = 84
x = 84/7
x = 12
Substitute the value of x to the equation 1,
7(12) - 12y = 180
12y = 84 - 180
y = -96/12
y = -8
Therefore, x = 12 and y = -8 is the solution.

Answer:
8c + 6 = 3
Step-by-step explanation:
six more than the product of a number and 8 is 3
the product of 8 and c is 8•c, which can also be written as 8c. 6 more than that means you are adding 6, and getting 3... so your equation is,
8c + 6 = 3

Solve the equation by completing the
square. Enter the smallest solution first
and round to the nearest tenth.
s? - 8s - 4 = 0
-
s = [?]
Answer:
s ≈ - 0.5 , s ≈ 8.5
Step-by-step explanation:
s² - 8s - 4 = 0 ( add 4 to both sides )
s² - 8s = 4
To complete the square
add ( half the coefficient of the s- term )² to both sides
s² + 2(- 4)s + 16 = 4 + 16
(s - 4)² = 20 ( take square root of both sides )
s - 4 = ± [tex]\sqrt{20}[/tex] ( add 4 to both sides )
s = 4 ± [tex]\sqrt{20}[/tex]
Then
s = 4 - [tex]\sqrt{20}[/tex] ≈ - 0.5 ( to the nearest tenth ) ← smaller solution
s = 4 + [tex]\sqrt{20}[/tex] ≈ 8.5 ( to the nearest tenth ) ← larger solution

Answer:
9 + 4 = $13, Ms. Brown has 10 dollars which is not enough to pay for both Cranberry and Granola.
Step-by-step explanation:
Alright, so Cranberry is 3.25 per pound, and Granola is 2.19 per pound.
(2.9 and 1.75 is how many pounds of both Cranberry and Granola she wants.)
2.9 × 3.25 = 9.4
1.75 × 2.19 = 3.8
So when rounding, 9.4 would be rounded to 9. Then 3.8 would be rounded to 4. So no, Ms. Brown doesn't have enough to pay for both. 9 + 4 = $13
Have a good day friend! :D
Answer:
Let us use the variable "x" to represent the cost per Ib for each mix.
Cranberry: x = 2.9
Granola: x = 1.75
Ms.Brown buys 1.75 pounds of granola and 2.9 pounds of cranberry. Since the cost per pounds represent x, we can write the follow:
[tex]2.19(1.75)+3.25(2.9)[/tex]
[tex]3.83 + 9.42 = 13. 25[/tex]
Round to nearest cent,
Total Cost= $13
Since it is given that Ms.Brown has a $10 budget, she won't have enough for the purchase. She'll need $3 more.
