Answer:
Step-by-step explanation:
Taking equation (1)
Multiplying both sides by 2
Adding 6y to both sides
Putting this in (2)
5(18+6y) + y = 28
5(18+6y) + y = 28
90 + 30y+y = 28
31y+90-28 = 0
31 y + 62 = 0
31y = -62
Dividing both sides by 31
y = -2
Now,
x = 18 + 6y
x = 18+6(-2)
x = 18-12
x = 6
The answer is 3.
the equation: 4x+6+3=17
4x+9=17
subtract 9 from both sides
4x=12
x=3
check by inserting 3 as x into the original equation
4*3+6+3=17
hope this helps!
Answer: Yes he will be
Step-by-step explanation:
To find out if Ted can afford the car, find the future value of $4,300 in three years.
First convert the number of years and rates to quarterly values as this is the compounding period:
Term = 3 * 4 quarters = 12 quarters
Rate = 5.5% / 4 = 1.375% per quarter
Future value = Amount * ( 1 + rate) ^ term
= 4,300 * ( 1 + 1.375%)¹²
= $5,065.69
<em>Considering that Ted makes $5,065.69 in 3 years, he will be able to buy a car that costs $4,700.</em>
Given:
The equation is
The incorrect solution steps are given.
To find:
The first error.
Solution:
We have,
Using distributive property, we get
The given step 1 is 
, which is not correct.
Therefore, there is first error in step 1 because the distribution property is not used properly.
Hence, the correct option is D.
