Answer:
y=3
x=2
Step-by-step explanation:
Making substitution
y+7=5x
y=5x-7
Substituting the y into the other equation
-3x-2(5x-7)=-12
-3x-10x+14=-12
-13x=-14-12
-13x=-26
x=2
We have x=2 then substitute it into the first equation
y+7=5(2)
y+7=10
y=10-7
y=3
So the answer is
y=3
x=2
Answer:
x=2 and y=3
Step-by-step explanation:
After solving, you can check your work by substituting the values of x and y into the equations and solving for them.
3+7=10
10=10
-6-6= -12
-12 = -12

there are 16 students working on a project if each student need 1/4 stick of clay are needed in all?
Answer:
4 sticks of clay
Step-by-step explanation:
To find the total amount of clay needed, multiply the number of students by the amount need for each one of them.
[tex]16[/tex] · [tex]\frac{1}{4}[/tex]
Multiply these by converting 16 into a fraction.
[tex]\frac{16}{1}[/tex] · [tex]\frac{1}{4}[/tex]
Multiply the numerators and denominators across.
[tex]\frac{16}{1}[/tex] · [tex]\frac{1}{4}=\frac{16}{4}[/tex]
Simplify this.
[tex]\frac{16}{4} =4[/tex]
The total amount of clay needed is 4 sticks.
I hope this helps :) Good luck ^^

In an arithmetic sequence, the first term, a_1,a
1 , is equal to 5,5, and the fifth term, a_{5},is equal to 41.41. Which number represents the common difference of the arithmetic sequence?
Answer:
10
Step-by-step explanation:
The general term of an arithmetic sequence is given by ...
an = a1 +d(n -1) . . . . where a1 is the first term and d is the common difference
__
This formula can be used to find the value of d. The first term is given as 1, and the 5th term (a5) is given as 41. The value of n for the 5th term is 5.
an = a1 +d(n -1)
41 = 1 +d(5 -1) . . . . . substitute known values
40 = 4d . . . . . . . subtract 1, simplify
10 = d . . . . . . divide by 4
The common difference of this sequence is 10.

After 1 year, $1,000 deposited in a savings account with simple interest had earned $30 in interest. What was the interest rate?
Answer:
3%
Step-by-step explanation:
The formula for simple interest is I = PRT, where I = interest earned/paid, P = principal amount deposited or borrowed, R = rate of interest as a decimal, and T = time in years.
I = PRT
30 = (1000)(R)(1)
30 = 1000R
R = 0.03
Multiply by 100 to get the percentage of 3%

2^28 is the number 2 multiplied 28 times.
2^28 = 268,435,456
Step-by-step explanation:
Since exponents are repeated multiplication, you would have to multiply "2" 28 times.
Like this, 2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2.
The product of 2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2 is 268,435,456.

Elijah bought a new car for $25,000. He paid
$5,000 up front and then $600 per month. How
many months will it take Elijah to pay off the car?
Answer: 6 days too be exact
Step-by-step explanation:
Answer:
33.333 months
Step-by-step explanation:
25,000-5,000=20,000
20,000/600=33.333
If he payed $5,000 upfront, the he only has $20,000 remaining to pay. If he is paying $600 a month then you divide the $20,000 by the $600 to 33.333 months. Hope this helps

Answer:
G
Step-by-step explanation:
In the equation, 8.5 will represent how much money Oscar earns per hour, and the x represents how many hours he works. The inequality sign shows that the sum of 8.5x and 100 has to be at least 397.50 (397.50 and up), so H and J are automatically wrong. If Oscar had given his brother 100 dollars, there would be a subtraction sign, but there is an addition sign instead, meaning he gained 100 dollars that did not come from his job. It would be the most logical to say that his brother had given it to him, so G is the correct answer.
