Answer:
3) Verify the following: (a) 48 = 48, TRUE (b) 230 = 230, TRUE
Step-by-step explanation:
3) Verify the following:
a. 16 [7 + (-4)] = [16 × 7] + [16 × (-4)]
= 16 [7 -4] = [112] + [16 × -4]
= 16 [3] = [112] + [-64]
= 48 = 112 - 64
= 48 = 48
This is true because both sides are equal.
b. -23 × [(-8) + (-2)] = [(-23) × (-8)] + [(-23) × (-2)]
= -23 × [-8 - 2] = [-23 × -8] + [-23 × -2]
= -23 × [-10] = [184] + [46]
= -23 × -10 = 184 + 46
= 230 = 230
This is true because both sides are equal.

lilli has $3.65 comprised of quarters and dimes floating on the bottom of her bag she has five more dimes than twice her quarters how many each type of coin does she have? lol pls help
Answer:
= 3.65.
Step-by-step explanation:
You know that Tom has 23 coins in total. That means the number of dimes and the number of quarters equals 23.
D + Q = 23
You also know that the total value of the coins is $3.65. A dime is worth $0.10 and a quarter is worth $0.25, so:
0.10*D + 0.25*Q = 3.65
That says that 10 cents per dime times the number of dimes, plus 25 cents per quarter times the number of quarters is three dollars and sixty-five cents.
So you have a system of linear equations:
D + Q = 23
0.10D + 0.25Q = 3.65
I'm going to multiply the bottom row by 100 to clear the decimals.
D + Q = 23
10D + 25Q = 365
Now I can multiply the top row by -10 to eliminate the D terms
-10D - 10Q = -230
10D + 25Q = 365
________________
0D + 15Q = 135
15Q = 135
Q = 9
Tom has 9 quarters.
If D + Q = 23, and Q = 9, then:
D + 9 = 23
D = 14
Tom has 14 dimes.
Always good to double check:
9 quarters is worth $2.25. 14 dimes is worth $1.40. These should sum to $3.65.
2.25 + 1.40

Step-by-step explanation:
5(3r+11)=85
I'm confused on how to do this, and if i'm doing it right. Do I times the 5 by the 3 and then by the 85 so its on both sides? Ah! I don't know what im doing...
Answer:
r = 2
Step-by-step explanation:
Actually, there are 2 ways to solve this equation.
The first one:
5( 3r + 11) = 85
so here, you have to multiply 5 by ( 3r + 11) and maintain the 85
15r + 55 = 85... now put the like terms together. In other words, just transpose 55 to the other side.
15r = 85 -55..... remember that the sign of 55 will change from positive to negative
15r = 30.... now divide both sides by 15
15r/15 = 30/15
r = 2
The second method :
5 ( 3r + 11) = 85...... divide both sides by 5
5 (3r + 11) / 5 = 85/5
3r + 11 = 17
3 r = 17 - 11
3r = 6
r = 2
I hope this helps. If you don't quite get it, please go through until you get it. Have a nice day :-)
Answer:
r = 2
Step-by-step explanation:
5(3r + 11) = 85
~Use distributive property
15r + 55 = 85
~Subtract 55 to both sides
15r = 30
~Divide 15 to both sides
r = 2
Best of Luck!

If you were to measure a straight line from New York to Hong Kong it would measure 12.6 cm. If the scale of the map says that 3000 miles are 3.2 cm, what is the distance between New York and Hong Kong in miles?
Answer:
11812.5 milesStep-by-step explanation:
Given:
3000 miles → 3.2 cmx miles → 12.6 cmSolve for x by cross-product:
3.2x = 3000*12.6x = 37800/3.2x = 11812.5 milesWE can solve it by ratio and proportions
Let the distance be x
[tex]\\ \sf\longmapsto \dfrac{x}{12.6}=\dfrac{3000}{3.2}[/tex]
[tex]\\ \sf\longmapsto 3.2x=3000(12.6)[/tex]
[tex]\\ \sf\longmapsto 3.2x=37800[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{37800}{3.2}[/tex]
[tex]\\ \sf\longmapsto x=11812.5mi[/tex]

Find the median of the data: 22, 16, 14, 26, 32 and 30

Have a great day
Answer:
[tex]\boxed {\boxed {\sf 24}}[/tex]
Step-by-step explanation:
We are asked to find the median of the following data set:
22, 16, 14, 26, 32, 30The median is the middle number of the data set. It separates the higher half of the set from the lower half. We put the data set in order from least to greatest and find the middle number.
14, 16, 22, 26, 30, 32We eliminate a number from each side of the data set until we find the middle number.
16, 22, 26, 3022, 26However, the data set had 6 numbers, which is an even number. There isn't one middle number, so we must find the average of the middle 2 numbers. Add the numbers and divide by 2.
22+ 26 = 48 48 / 22= 24The median of the data set is 24.
