Answer:
[tex]4x + 8[/tex]
Step-by-step explanation:
Hi!
So we have to use the distributive property here and distribute 4 to both the x and the 2.
So we do
[tex](4*x)+(4*2)[/tex]
Simplify further:
[tex]4x + 8[/tex]
That's your answer

Mr. Tyssee got a haircut, which cost $35. He gave the
stylist a 15% tip. How much will he pay for the haricut
including tip?
Answer:
$40.25
Step-by-step explanation:
15% = 0.15, so multiply 35 * 0.15 = 5.25 to get the tip.
Since the answer is asking for both the tip and the cost, add 35 + 5.25, which gives the answer $40.25

A bag contains 5 red marbles, 3 blue marbles, 7 yellow marbles, and 2 green marbles. Which ratio can be used to compare the red
marbles to the blue marbles?
A) 3/5
B) 3/8
C) 5/3
D) 5/8
Answer:
C) 5/3
Step-by-step explanation:
The ratio comparing red to blue marbles can be created by putting 5 and 3 together, since there are 5 red marbles and 3 blue marbles
This gets you 5/3
So, the correct answer is C) 5/3
Answer:
5/3
Step-by-step explanation:
This is because there are 5 red marbles and there are 3 blue marbles. If you put them side by side, the ratio is 5:3 or 5/3.

Step-by-step explanation:
George has cut down a 60ft high oak tree. He now wants to chop it into smaller pieces. He first cuts it into two pieces that are both 30ft. And then he continues on into making ten pieces that all are 6ft long before loading them onto his truck.
picture08
By looking at the different pieces of wood we can see that the following holds true.
60=30+30=6+6+6+6+6+6+6+6+6+6
This is called the reflexive property of equality and tells us that any quantity is equal to itself
a=a
We can also use this example with the pieces of wood to explain the symmetric property of equality. This property states that if quantity a equals quantity b, then b equals a.
ifa=b,thenb=a
Or if we use our example
if60=30+30,then30+30=60
Another property that can be explained by this is the transitive property of equality. It tells us that if a quantity a equals quantity b, and b equals the quantity, c, then a and c are equal as well.
ifa=bandb=c,thena=c
Or in the numbers taken from the oak tree example
if60=30+30
and30+30=6+6+6+6+6+6+6+6+6+6
then60=6+6+6+6+6+6+6+6+6+6
Since we know that 30 + 30 = 20 + 40 and that 30 + 30 = 60 we can substitute 30 + 30 for 20 + 40 and get 60 = 20 + 40. This is called the substitution property of equality.
If a = b, then a can be substituted for b in any expression.George has cut down a 60ft high oak tree. He now wants to chop it into smaller pieces. He first cuts it into two pieces that are both 30ft.

Answer:
66.6667
2 out of 66.6667 is 3%
Step-by-step explanation:
2 out of what is 3%?
2 out of X is 3%
Equation: Y/X = P%
Solving our equation for X
X = Y/P%
X = 2/3%
Converting percent to decimal:
p = 3%/100 = 0.03
X = 2/0.03
X = 66.6667

Step-by-step explanation:
How do you solve for x and y?
Answer:
x = 60°, y = 30°
Step-by-step explanation:
The sum of the triangle angles is always 180°
Therefore 90° + x + y = 180°
It is also known that x = 2y
// combine the given value of x into the previous expression
90° + 2y + y = 180°
2y + y = 180° - 90°
3y = 90°
// divide both sides by 3
y = 30°
// then combine the given value of y into the expression x = 2y
x = 2 * 30°
x = 60°

HI SOMEONE PLEASE HELP I HAVE NO IDEA HOW TO DO THIS :(( i need to know the measure of angles 13 and 12 then the measure of the line segment SG. Thank you sm in advance
Answer:
Angle 13 equal 90 and Angle 12 equal 45
Step-by-step explanation:
This is a square so all of the corner angles and the diagonals angles measure 90 degrees. A square also forms 4 congruent isoceles triangles or technically 45-45-90 triangles. So that means the following angles measure 45 degrees since they share a point
Angle 5,6,7,8,9,10,11,12. So the measure of 12 is 90 degrees.
To find the measure of 13, in a square diagonals bisect each other and form perpendicular lines so that means every angle in the middle of the square measure 90 degrees.
Using that
Angle 13,15,16 and R measure 90 degrees so Angle 13 equal 90.

If you randomly select a card from a well-shuffled standard deck of 52 cards, determine the probability that the card you
select is a King
a) Write your answer as a reduced fraction,
b) Write your answer as a decimal, rounded to the nearest thousandth.
c) Write your answer as a percent. Round to the nearest tenth of a percent as needed.
Answer:
a) 1/13
b) 0.077
c) 7.69%
Step-by-step explanation:
4 kings in a standard 52 card deck. Just find the fraction of 4/52 and then you will be able to find the percent, decimal and of course, fraction.
Answer:
Here are all 52 cards
A♥ 2♥ 3♥ 4♥ 5♥ 6♥ 7♥ 8♥ 9♥ 10♥ J♥ Q♥ K♥
A♦ 2♦ 3♦ 4♦ 5♦ 6♦ 7♦ 8♦ 9♦ 10♦ J♦ Q♦ K♦
A♠ 2♠ 3♠ 4♠ 5♠ 6♠ 7♠ 8♠ 9♠ 10♠ J♠ Q♠ K♠
A♣ 2♣ 3♣ 4♣ 5♣ 6♣ 7♣ 8♣ 9♣ 10♣ J♣ Q♣ K♣
Here are all the cards that are either a club or a 5:
5♥
5♦
5♠
A♣ 2♣ 3♣ 4♣ 5♣ 6♣ 7♣ 8♣ 9♣ 10♣ J♣ Q♣ K♣
Count them. There are 16.
So the probability is 16 out of 52 or 16/52 which reduces to 4/13.
Step-by-step explanation:
Step 1: figure out the total number of cards you might pull.
Write down all the possible cards and mark the ones that you would pull out (in our case we’ve been asked the probability of a club or a seven so we’re going to mark all the clubs and all the sevens):
hearts: 2, 3, 4, 5, 6, 7, 8, 9, 10, j, q, k, A
clubs: 2, 3, 4, 5, 6, 7, 8, 9, 10, j, q, k, A
spades: 2, 3, 4, 5, 6, 7, 8, 9, 10, j, q, k, A
diamonds: 2, 3, 4, 5, 6, 7, 8, 9, 10, j, q, k, A
This totals 16 cards. *
Step 2: Count the total number of cards in the deck(s). We have one deck, so the total = 52
Step 3: Write the answer as a fraction. Divide step 3 by Step 4:
16 / 52

Sunita creates a scale model of an aeroplane. The scale of the model is 4 cm to 15 m. Sunita's model has a wingspan of 17 cm. What is the wingspan of the real aeroplane?
Answer:
36.43m
Step-by-step explanation:
Let the wingspan of the real aeroplane = x
The scale of the model is 4 cm to 15 m.
= 4: 15 = 4/15.
Sunita's model has a wingspan of 17cm.
Hence:
4cm/15m = 17cm/xm
Cross Multiply
4x = 15 × 17
4x = 255
x = 255/4
x = 36.428571429 m
Approximately = 36.43 m
Therefore, the wingspan of the real aeroplane is 36.43m

Two fair dice are rolled at the same time. What is the probability that one die will show 3 and the other will show 4? A. 1/36
B. 1/18
C. 1/12
D. 1/6
Answer:
1/36
Step-by-step explanation:
There are 6 numbers on a die. You have a 1/6 chance of rolling a 3 and a 1/6 chance of rolling a 4. 1/6 times 1/6 = 1/36.
Mr. Bayless invests $3500 in a savings plan. The savings account pays an
annual interest rate of 4.75% on the amount he put in at the end of the
year. How much will Mr. Bayless earn if he leaves his money in the savings
plan for 8 years and how much money will be in his savings plan at the end
of 8 years?
Answer:
Interest = $1330
Amount = $4830
Step-by-step explanation:
Given
Principal = $3500
Rate = 4.75%
Time T = 8 years
Interest =PRT/100
Interest = 3500*4.75*8/100
Interest = 35*4.75*8
Interest = $1,330
Hence the interest earned by Mr. Bayless is $1,330
Amount after 8years = Principal + Interest
Amount after 8years = 3500+1330
Amount after 8years = $4830
Hence the amount after 8years is $4830
