(2x+y,x+3y)=(12,11)
Answers
Answer:
x=5, y=2
Step-by-step explanation:
Use the information given:
2x+y=12x+3y=11Subtract them because we have two variables and two equations:
2x+y=12
- x+3y=11
–––––––––
x-2y=1
We can by 1+2y (Add 2y to both sides) instead of x:
2(1+2y)+y=122+4y+y=122+5y=125y=10y=2(1+2y)+3y=111+2y+3y=111+5y=115y=10y=2Now we can figure out x as we know y:
2x+1(2)=122x+2=122x=10x=5x+3(2)=11x+6=11x=5How do I solve this equation and check the solutions?

Tommy bought a total of 30 apples and oranges for a classic picnic. Apple's cost $3 per pound and oranges cost $4 per pound. Tommy spent $100 total. How many apples and oranges did Tommy buy?
Please show work and explain
Answers
Solution: (20,10) Tommy bought 20 apples and 10 oranges.
Step-by-step explanation:
x+y=30: y=30-x
3x+4y=100
3x+4(30-x)=100
3x+120-4x=100
-1x +120=100
-120 -120
-1x=-20
/-1 -1
x= 20
20+y= 30
-20 -20
y=10
20+10=30

Answer:
x=6
Step-by-step explanation:
divide each term by 2 then simplify
Answer:
6
Step-by-step explanation:
First what you do is you subtract 7 from both sides to get 2x by itself.
2x + 7 - 7 = 19 - 7
2x = 12
Then you divide 2 from both sides to get x by itself.
2x/2 = 12/2
x = 6
Your answer is then x = 6.

Answer:
e. the triangles are congruent
Step-by-step explanation:
Similar means they're alike but are not the same, congruent means they're the same. The triangles are the same so therefore they're congruent.
Also it's congruent because u see the triangles on the bottom and top line? It means that the lines are parallel. So the lines at the side have to be the same length and tilt in an equal way so the top and bottom lines can be parallel
"Just look at the graph," the player's agent said. "Phil's hits have doubled since last year. We are looking for a large raise and a long contract." Look at the graph. A bar graph titled Phil's hits has this year and last year on the x-axis, and number on the y-axis, from 100 to 200 in increments of 20. This year is 180, and last year is 120. How can you redraw this graph so it appears that Phil's hits have quadrupled since last year. a. Use the same scale and make the top bar twice as thick as the bottom bar. b.

Eva bought 9 hanging baskets and 9 Petunias for her flower garden. Each hanging basket cost $5.48 and each Petunia cost $18.50. Eva has $250 to spend on items for her garden. How much money will Eva have left after her purchases?
Answers
Answer: Eva has left $ 34.18 after her purchases .
Step-by-step explanation:
Given: Each hanging basket cost $5.48
Cost of 9 hanging basket = 9 x $5.48 = $ 49.32
Each Petunia cost $18.50.
Cost of 9 Petunias = 9 x $18.50
= $ 166.5
Eva has $250 to spend on items for her garden.
Money left = $(250 -(49.32+166.5))
= $ (250 -215.82)
= $ 34.18
Hence, Eva has left $ 34.18 after her purchases .
Ms. Hogan paid $13.25 for 5 tacos and 1 soda. The price of a taco is $2.50. What is the price of the soda?
Answers
Answer: $0.75
Step-by-step explanation:
To solve this problem, we can create 2 equations. Let's use x for tacos and y for soda.
Equation 1: 5x+y=13.25
Equation 2: x=2.5
Since we know the value of x, we can plug it into Equation 1 to solve for y.
5(2.5)+y=13.25 [multiply]
12.5+y=13.25 [subtract both sides by 12.5]
y=0.75
Now, we know the price of the soda is $0.75.
Answer:
The soda costs $0.75.
Step-by-step explanation:
We are given that Ms. Hogan paid $13.25 for 5 tacos and one soda. We are also given that one taco costs $2.50. Therefore, we can set up a system of equations to solve for how much a soda costs.
[tex]\displaystyle\left \{ {{5x + y = \$13.25} \atop {x = 2.50}} \right.[/tex]
This is our required system of equations. We are given that one taco costs $2.50, so this is our x. Therefore, the price of one soda is y.
We can use the second equation and substitute it in place of the x in the first equation to solve for the price of the soda.
[tex]\displaystyle5x+y=\$13.25\\\\5(2.50)+y=\$13.25\\\\12.5 + y = \$13.25\\\\y = \$0.75[/tex]
Therefore, one soda costs $0.75.

The volume of a solid cube is 1700m3.
Work out the surface area.
Give your answer rounded to 1 DP.
Answers
Answer:
849.7m2
Step-by-step explanation:
L= length
SA = surface area
volume = L x L x L
1700= L x L x L
find cube root
=11.93m
round off to 1 dp
=11.9m
SA= 6( L x L)
= 6( 11.9 x 11.9)
=6(141.61)
=849.66m2
round off to 1 dp

∠A and \angle B∠B are vertical angles. If m\angle A=(3x+26)^{\circ}∠A=(3x+26) ∘ and m\angle B=(x+20)^{\circ}∠B=(x+20) ∘ , then find the value of x.
Answers
Answer:
The value of x is -3
Step-by-step explanation:
The vertical angles are equal in measures∵ ∠A and ∠B are vertical angles
→ By using the rule above
∴ m∠A = m∠B
∵ m∠A = (3x + 26)°
∵ m∠B = (x + 20)°
→ Equate their measures
∴ 3x + 26 = x + 20
→ Subtract x from both sides
∵ 3x - x + 26 = x - x + 20
∴ 2x + 26 = 20
→ Subtract 26 from both sides
∵ 2x + 26 - 26 = 20 - 26
∴ 2x = -6
→ Divide both sides by 2
∵ [tex]\frac{2x}{2}[/tex] = [tex]\frac{-6}{2}[/tex]
∴ x = -3
∴ The value of x is -3

-3.5 = - 6
right hand side not equal to left hand side of this equation.so,x= -2 cannot exist for this equation.

(x - 5) / 2= -6
(2 - 5) / 2= -6

Mrs. Coughlin bought 2.25 pounds of turkey at $4.96 per pound and 0.75 pound of provolone cheese at $5.20 per pound. If Mrs. Coughlin gave the cashier $20, how much change will she receive?
Answers
Answer:
$4.94
Step-by-step explanation:
To find out the change from $20, we need to find her total cost.
Total cost = 2.25lbs * $4.96/lb + 0.75lbs * $5.20/lb
Total cost = $11.16 + $3.90 = $15.06
Now $20 - total cost = $20 - $15.06 = $4.94
