Step-by-step explanation:
Hope this helps!!!
The required mass of Aunt jane is given as 4.5 kilograms.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
Given that, Aunt Jane weighs 45 newtons.
So,
F = 45
Since F = Mg,
Mg = 45
M(10) = 45
N = 4.5 kilograms,
Thus, the required mass of Aunt jane is given as 4.5 kilograms.

Which expressions are equivalent to 7(-4/3 x -3)? Select two options.
Answer:
Step-by-step explanation:
7(-3/4x-3) is the same as
7(-3/4x)-7(3) and
-5 1/4x-21
Let me explain this a little bit more.
If you take the 7 times the first part or -3/4x you get 7(-3/4x) You take 7 times the second part you get -7(3)
When you actually solve them:
7(-3/4x) = -5 1/4x and -7(3) = -21.

Answer:
10 centimeters = 0.1 meters
Step-by-step explanation:
Question
How many meters are in 10 centimeters?
There are 100 centimeters in 1 meter.
Therefore, 1 centimeter = 1 ÷ 100 meters
= 0.01 meters
So if 1 centimeter = 0.01 meters
Then 10 centimeters = 0.01 × 10 = 0.1 meters

Two adults and one child go to a movie and pay $26. One adult and 3 children pay
$28. How much would it cost for one adult and one child to see the movie?
Answer:
adults pay $10
children pay $6
Step-by-step explanation:
x = adult
y = child
2x + y = 26
x + 3y = 28
you want to cancel out x or y
multiply -2 with (x + 3y = 28) which is -2x -6y = -56
2x + y = 26
-2x -6y = -56
-5y = -30
y = 6
put y back into an equation
2x + y = 26 is
2x + 6 = 26
x = 10
check the answer
Two adults and one child go to a movie and pay $26
20 + 6 = 26 : checks
One adult and 3 children pay $28
10 + 18 = 28 : checks

You have 12 coins. Some quarters and dimes. You have a total of $2.40, how many of each coin do you have?
Answer:
8 quarters and 4 dimes
Step-by-step explanation:
4 quarters = 1 dollars
4 quarters = 1 dollars
4 dimes = 40 cents
2.40$
============================================
Work Shown:
d = number of dimes
q = number of quarters
1 dime = 10 cents
d dimes = 10d cents
1 quarter = 25 cents
q quarters = 25q cents
d+q = 12 since we have 12 coins total
q = -d+12 after solving for q
10d+25q = total value in cents
10d+25q = 240
10d+25(-d+12) = 240 ... plug in q = -d+12
10d-25d+300 = 240
-15d+300 = 240
-15d = 240-300
-15d = -60
d = -60/(-15)
d = 4
q = -d+12
q = -4+12
q = 8
Since d = 4 and q = 8, this means we have 4 dimes and 8 quarters
-----------------------------
Check:
4 dimes = 4*10 = 40 cents
8 quarters = 8*25 = 200 cents
(4 dimes) + (8 quarters) = (40 cents) + (200 cents) = 240 cents
240 cents = 240/100 = $2.40
We have 4+8 = 12 coins total

Melanie invested $63,000 in an account paying an interest rate of 7\tfrac{1}{8}7

% compounded quarterly. Lillian invested $63,000 in an account paying an interest rate of 7\tfrac{3}{8}7
8
3
% compounded continuously. After 15 years, how much more money would Lillian have in her account than Melanie, to the nearest dollar?
Answer:
$8727
Step-by-step explanation:
The difference in investment values can be found by computing the value of each investment, then finding the difference. Here, we're concerned with investments compounded quarterly and compounded continuously.
a)Melanie's investment value is computed using the formula ...
FV = P(1 +r/n)^(nt) . . . . where P is the principal, r is the annual rate, t is the number of years
FV = $63,000(1 +0.07125/4)^(4×15) = $63,000(1.0178125^60)
FV = $181,721.94
__
b)Lillian's investment value is computed using the formula ...
FV = Pe^(rt)
FV = $63,000·e^(0.07375×15)
FV = $190,449.05
__
c)The amount more that Lillian has is ...
$190,449.05 -181,721.94 = $8,727.11
Lillian has about $8727 more than Melanie.

deli last month was $640. What was the total sales for the deli last
month?
Answer:
$2000
Step-by-step explanation:
The profit is the money earned by the store, meaning in this case, it's 32%. 32 percent of an amount is equal to 640. Set up an equation: 0.32(x) = 640, where x is the total money earned including the profit. x is solved to be 2000 dollars.

Step-by-step explanation:
1) Convert both sides to the same base.
[tex]16^{1.5x^{2} } =16^{2x}[/tex]
2) Cancel the base of 16 on both sides.
[tex]1.5x^{2} =2x[/tex]
3) Move all terms to one side.
[tex]1.5x^{2} -2x=0[/tex]
4) Factor out the common term x.
[tex]x(1.5x-2)=0[/tex]
5) Solve for x.
