Solve the system by substitution.
1. y= 7x
x − 7y = -48
Screen Shot of answer
source:Mathwa.y
Answer:
x=1
y=7
Explaination:
y=7x---------(1)* *First equation
x-7y=(-48)----(2)* *Second equation
Put (1)* into y on (2)*
x-7(7x)=(-48)
x-49x=(-48)
-48x=(-48)
48=48x
48÷48=x
1=x or x=1--------(3)* *Third equation
Put (3)* into (1)*
y=7(1)
y=7

Answer:
11.66
Step-by-step explanation:
As far as I remember the Pythagorean theorem states that A squared + B squared = C Squared. A and B are your 2 input numbers so therefor 6squared + 10squared =136 but you have to find the Square root of that because you added the other two squared numbers. Your answer is approximately 11.661903

Find missing side? Soh cah toa
Answer:
x ≈ 14.6
Step-by-step explanation:
Using the sine ratio in the right triangle
sin59° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{17}[/tex] ( multiply both sides by 17 )
17 × sin59° = x , then
x ≈ 14.6 ( to 1 dec. place )

how do you solve this two step equation? 5 -2/3x =3
Answer:
x = 3
Step-by-step explanation:
I will assume you meant 5 - (2/3)x = 3. This simplifies to -(2/3)x = -2, or
(1/3)x = 1, so that x = 3.

"2/3x" could be interpreted as --------- which would give us a very different

Leslie rolls two fair number cubes numbered from 1 to 6. She first defines the sample space, as shown below:
(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6)
(2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6)
(3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6)
(4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6)
(5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6)
(6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)
Based on the sample space, what is the probability of getting a total of 11? (5 points)
2 over 36
3 over 36
4 over 36
5 over 36
Answer:
67
Step-by-step explanation:
Answer:
2 over 36
Step-by-step explanation:
The only way to get an 11 is with a 5 and a 6 so the probability of rolling a sum of 11 is:
(2/6)(1/6)=2/36
What is the solution to this using substitution method pls show ur work
Answer:
x=-6, y=0
Step-by-step explanation:
Use the 3x-9y=-18 equation and add 9y to both sides to have 3x on its own on the left side. Then, divide by 3 on both sides. Then you'll have x=-6+3y. Plus this back into the 5x+4y=-30 equation and you'll get 5(-6+3y)+4y=-30. Use the distributive property and you'll get -30+15y+4y=-30. Simplify and get -30+19y=-30, then add 30 to both sides and you'll get 19y=0. Divide by 19 on both sides and you'll get y=0. Now that we know y=0, plug that back into the 5x+4y=-30 equation, and you'll get 5x+4(0)=-30. Simplify and you'll get 5x=-30. Divide by 5 on both sides and you'll get x=-6.

Wendy and Connor each deposit 8,300 into accounts that earn 3.5% interest for 25 years Wendy's account earns annual simple interest sand Connor's account earns an annual compound interest who will earn more interest of 25 years and how much interest they will earn
Answer:
Connor will earn more interest because he is getting compound interest.
Step-by-step explanation:
I have to assume in this case that the interest is 3.5% Per year:
Simple Interest = P(r + t)
{P = Principle, r = interest rate, t = time)
Wendy = $8,300 x (3.5% x 25)
Wendy = $7,262.50 (2 d.p)
Wendy = $8,300 + $7,262.50
Wendy = $15,562.50
Compound Interest = [tex]P (1 +r )^{t}[/tex]
{P = Principle, r = interest rate, t = time)
Connor = $8,300 x [tex](1 + 0.035)^{25}[/tex]
Connor = $19,614.93
Wendy's Interest = $15,562.50 - $8,300 = $7,262.50
Connor's interest = $ 19,614.93 - $8,300 = $11,314.93
Connor earned more interest by $4,052.43
