If x - 8 = -10, then find the value of 4x - 12
Answer:
60 is your answer.
Step-by-step explanation:
x - 8 = 10
add 8 to both sides,
x = 18
substitute 18 for x in the second equation:
4(18) - 12 = 72 - 12 = 60
Please lmk if you have questions.
what is the range of g?
Answer:
B.
Step-by-step explanation:
The values for g(x) divert after the point -1.
So, the values are going to be equal or greater than -1.
Alan invests a total of $16,500 in three different ways. He invests one part in a mutual fund which in the first year has a return of 11%. He invests the second part in a government bond at 7% per year. The third part he puts in the bank at 5% per year. He invests twice as much in the mutual fund as in the bank. The first year Alan's investments bring a total return of $1,425. How much did he invest in each way?
Answer:
>> $9000 invested in mutual fund
>> $3000 invested in government bond
>> $4500 put in the bank
Step-by-step explanation:
Let us denote the money invested in each case by a letter. Thus;
a = the money that he invested in a mutual fund
b = the money that he invested in a government bond
c = the money that he put in the bank
We are told that he invested a total of $16,500. Thus;
a + b + c = 16500 - - - (eq 1)
He invested twice as much in the mutual fund as he did in the bank. Thus;
a = 2c - - - (eq 2)
From the percentage given and the return of $1,425 from the first year investments, we have;
0.11a + 0.07b + 0.05c = 1425 - - - (eq 3)
Let's put 2c for a in eq (1) and eq (3)
Thus;
2c + b + c = 16500
b + 3c = 16500 - - - (eq 4)
Also,
0.11(2c) + 0.07b + 0.05c = 1425
0.07b + 0.27c = 1425 - - - (eq 5)
From eq 4, b = 16500 - 3c
Putting this in eq(5) gives;
0.07(16500 - 3c) + 0.27c = 1425
1155 - 0.21c + 0.27c = 1425
0.06c = 1425 - 1155
0.06c = 270
c = 270/0.06
c = $4500
b = 16500 - 3(4500)
b = 16500 - 13500
b = $3000
Since a = 2c, then;
a = 2(4500)
a = $9000
Ben earned $ 400 mowing lawns this month. Of his earnings, he plans to spend 18% repairing
lawn equipment, deposit 20% in his savings, and use 35% for clothes. He will spend the rest.
How much will Ben have left to spend Show your work. help ill mark brainlessly
Answer:
K 110
Step-by-step explanation:
Find the amount to be spent for each item/service
18% of $400= $72
20% of $400= $80
35% of $400= $140
Now, add all his expenditures and subtract it from his income
$400 - ($72+$80+$140) = $400 - $290 = $110

As we know that angle of semi circle is 180°.
Here,
FLG = 40°

HLJ = 60°
FLG + GLH + HLG = 180°
40° + GLH + 60° = 180°
GLH + 100° = 180°
GLH = 180° - 100°
GLH = 80°

Sean bought a laptop and a printer. He sold both items for £1,500 getting £1,300 just for the laptop. Sean made a 46% profit on the cost of the printer. What was the cost of the printer? Give your answer to 2 decimal places.
Answer: £137
Step-by-step explanation:
Since Sean sold both items for £1,500 getting £1,300 just for the laptop, the slave price of the printer will be:
= £1500 - £1300
= £200
Since we are informed that Sean made a 46% profit on the cost of the printer, the cost of the printer goes thus:
= £200 /(1 + Profit percent)
= £200 / (1 + 46%)
= £200 / 1.46
= £136.99
= £137 approximately

5. A cook needs 10 pounds of flour. He wants to spend the least amount of money. A 2-
pound bag costs $1.59 and a 5-pound bag costs $2.89, which should he buy in order to spend
less money? *
Answer:
He should buy two of the 5-pound bag.
Step-by-step explanation:
The cook needs 10 pounds of flour.
He wants to spend the least amount of money.
First option is a 5-pound bag for $2.89 each.
He can get 2 of the 5-pound bag which equals 10 pounds of flour for 2 x $2.89 = $5.78
Second option is a 2-pound bag for $1.59 each.
He can get 5 of the 2-pound bag which equals 10 pounds of flour for 5 x $1.59 = $7.95.
Second option is $2.17 costlier than the first option.
So, he should go for 2 of the 5-pound bag in order to spend the least amount of money while shopping for 10 pounds of flour.
