Answer:
g = 10
Step-by-step explanation:
Distribute 7 to the parentheses:
7(g + 5) = 105
7g + 35 = 105
Solve for g:
7g + 35 = 105
7g = 170
g = 10
So, the answer is g = 10
Answer:
g = 10
7g + 35 = 105
. -35 -35
7g = 70
g = 10

A toy story marks down every toy by 15% in January. How much does a toy cost during January?
Answer:
Well it all depends on the price of the toy.
So you are going to multiply the price of the toy and 15%. You will get the answer and subtract that number minus the price.
Example, a toy costs $30 in December, in January it will cost $25.50.
Step-by-step explanation:
30x15%= 4.5
30-4.5= 25.50
Answer:
just take 15% off what the toy is

Which of the following represents a "rule of thumb" for how much
student loan debt you should be willing to incur to pay for college?
Answer:
Rule of thumb is;
Your cumulative total student loans taken as at the time you are graduating should be less than your proposed annual starting salary.
Step-by-step explanation:
When calculating the loan a college student can afford, a rule of thumb comes in very handy which is that:
Your cumulative total student loans taken as at the time you are graduating should be less than your proposed annual starting salary.
This is because If your total student loan debt is less than your proposed annual income, it means all things being equal, you would be able to pay back the loan in about 10 years or less. However, if the loan debt exceeds your proposed income, it means you are likely to going to struggle and find it very difficult to repay your loan.

What is the value of x?
Answer:
x=131
Step-by-step explanation:
55 + 76 + x = 180
131 + x = 180
x = 49
subtract 49 from 180 to get x
180 - 49 = 131
*so um note that x should be greater than 90 degrees bc x is obvi an obtuse angle

The product of (2 + 7i) (2 - 7i) in the form of a + bi is 53 + 0i.
What is an imaginary number?An imaginary number is denoted by i.
The value of i is √-1.
i² = √-1² = -1
We have,
(2 + 7i) (2 - 7i)
We need to write in the form of a + bi.
a + bi
a = real number
b = imaginary part
(2 + 7i) (2 - 7i)
Remove the brackets.
= 2 x (2 - 7i) + 7i x (2 - 7i)
= 4 - 14i + 14i - 49i²
= 4 - 14i + 14i - 49 x -1
= 4 - 14i + 14i + 49
= 4 + 49
= 53
We have only the real part.
So,
The product of (2 + 7i) (2 - 7i) is 53 + 0i.
Thus,
The product of (2 + 7i) (2 - 7i) in the form of a + bi is 53 + 0i.

Laura invests $3600 in a savings account for 2 years. The account pays 3.52% compound interest per annum. Laura has to pay 40% tax on the interest earned each year. The tax is taken from the account at the end of each year. How much is in the account at the end of 2 years?
Answer:
$3753.64
Step-by-step explanation:
Initial amount = $3600
Interest rate = 3.52%
n = 1 (once in a year)
Time = 1 years
No of years = 2
Compound interest
A =[tex]P(1 + \frac{r}{n} )^n*t[/tex]
A = 3600(1 + 0.352/1) ^1*1= $3726.72
Interest earned = 3726.72 - 3600= $126.72
Tax = 40% of the interest earned= [tex]\frac{40}{100}*126.72[/tex] = $50.69 (This amount is deducted from interest )
Net interest earned after 1 year = 126.72 - 50.69= $76
Balance after 1 year = $3600 + $76= $3676
Similarly for the 2nd year
Compound interest
A =[tex]P(1 + \frac{r}{n} )^n*t[/tex]
A = 3676( 1+0.0352/1)^1*1= 3676(1.0352)
= $3805.4
Interest earned = 3805.4 - 3676= $129.4
Tax = [tex]\frac{40}{100}*129.4[/tex]= $51.76
Net interest earned =129.4 - 51.76= $77.64
Net balance after 2nd year = 3676+ 77.64= $3753.64

Answer:
x=-5/53
Step-by-step explanation:
1. Add similar elements: 4x+27x=31x
2. Multiply 13 times 2 to get 26
3. Once again add the similar elements: 31x+26x=57x
4. Expand!!: Originally (4x+1) take away the Parentheses!!
5. 57x+6=4x+1
6. Subtract 6 from both sides: 57x+6-6=4x+1-6
7. Simplify: 57x=4x-5
8. Subtract 4x from both sides: 57x-4x=4x-5-4x
9. Simplify: 53x=-5
10. Divide both sides by 53: 53x/53= -5/53

Given the sequence, 26, 13, 6.5, ..... find a) the 10th term and b) the sum of the first 18 terms
Answer:
a) 10th term is 0.051
b) The sum of first 18 terms of given sequence is 51.48
Step-by-step explanation:
We are given the sequence 26, 13, 6.5, ..... we need to find
a) 10th term
b) Sum of first 18 terms
Before solving we need to determine if the sequence is arithmetic or geometric
The sequence is arithmetic if common difference d is same.
The sequence is geometric if common ratio r is same.
Finding common difference d: 13-26 = -13, 6.5-13= -6.5
As common difference is not same so, the sequence is not arithmetic.
Finding common ratio r : 13/26 =0.5, 6.5/13= 0.5
As common ratio is same so, the sequence is geometric.
a) Finding common difference: 13-26 = -13, 6.5-13= -6.5
As common difference is not same so, the sequence is not arithmetic.
a) 10th term
The formula to find 10th term is: [tex]a_n=a_1r^{n-1}[/tex]
We have a₁=26 and r = 0.5 n=10
[tex]a_n=a_1r^{n-1}\\a_{10}=26(0.5)^{10-1}\\a_{10}=26(0.5)^{9}\\a_{10}=0.051[/tex]
So, 10th term is 0.051
b) Sum of first 18 terms
The formula to find sum of geometric series is: [tex]S_n=\frac{a(1-r^n)}{1-r}[/tex]
where a= 1st term, r = common ratio and n= number of terms
In the given sequence we have
a=26, r=0.5 and n=18
Finding sum of first 18 terms
[tex]S_n=\frac{a(1-r^n)}{1-r}\\S_{18}=\frac{26(1-(0.5)^{18}}{1-0.5}\\S_{18}=\frac{26(0.99)}{0.5}\\S_{18}=\frac{25.74}{0.5}\\S_{18}=51.48[/tex]
So, sum of first 18 terms of given sequence is 51.48

Here are the ingredients needed to make 8 pancakes.
Submit Ans

1 egg
140 g flour
5g butter
a)
Simon makes 4 pancakes.
Work out how much milk he needs.
b) Craig makes 12 pancakes.
Work out how much butter he needs.
Answer:
a) 125 ml milk
b) 7.5g butter
Step-by-step explanation:
a) 250ml of milk to make 8 pancakes
That means 125ml ((250/8) × 4 ml) of milk = 4 pancakes
b) 5g of butter = 8 pancakes
That means 7.5g ((5/8) × 12 g) of butter = 12 pancakes

2. How can the trend line equation be used to
predict the cost of gas per gallon in the year
1992?
a. Substitute 92 for x in the equation.
b. Substitute 92 for y in the equation.
c. Substitute 22 for x in the equation.
d. Substitute 22 for y in the equation.
Answer:
c. Substitute 22 for x in the equation.
Step-by-step explanation:
The scatter plot of this question is missing, so i have attached it.
The slope equation of this is written as;
y = mx + b
Where;
y is the values in the y-axis
x is the values in the x-axis
b is the intercept on the x-axis
Now, from the scatter plot of the trend line, we can see that the values in the x-axis represent the number of years after 1970 while the y-axis shows us the price of gas per gallon for each corresponding year.
Now, we want to use the trend line equation be used to predict the cost of gas per gallon in the year 1992.
Year 1992 means 22 years after 1992. Since we have our y-intercept from the scatter plot to be 0.25, then to find the cost of gas per gallon in the year 1992, we will just plug in 22 for x and 0.25 for b into the slope line equation.
