Answer:
x=7
Step-by-step explanation:
distributive property: multiply both terms in the parentheses by the term outside the parentheses (3)
3 times x = 3x
3 times -2= -6
3x-6=15
move -6 to other side by adding 6+15
3x=21
divide 21 by 3
x=7
Answer:
x=7
Step-by-step explanation:
Evalute to 3x-6=15, then add 6 to both sides. Then, divide 3 by both sides to get x by itself getting you a answer which becomes, x=7.

A geometric sequence starts with 10, 5, . . . Explain how you would calculate the value of the 100th term.
Answer:
The 100th term will be;
10(0.5)^99
Step-by-step explanation:
Firstly, we need the common difference and the first term
The first term is 10
The common difference is 5/10 = 1/2
Now, the formula for the nth term of a geometric sequence is;
ar^n-1
So, for the nth term, we have;
ar^(100-1)
= ar^99
So we have
10(1/2)^99
True or False? -|7| = |-7|
Explain please.
Answer:
False
Step-by-step explanation:
Notice how the negative symbol is outside the first number and inside the first number. If the negative symbol is outside the absolute value, the number will remain negative. If the negative symbol is inside the absolute value, the number will turn to positive.
Best of Luck!

Mr. Chen drives 26 miles to work every day. He drives the same distance to get back home. How many miles does he drive during a 5-day work week
Answer:
260 miles
Step-by-step explanation:
Given that,
Total distance driven by Mr. Chen everyday = 26 miles
He drives the same distance to get back home.
It means total distance driven by Mr. Chen to go and come back = 2(26) = 52 miles
We need to find how many miles does he drive during a 5-day work week.
Total distance = 5×52
= 260 miles
Hence, he will drive 260 miles during a 5 day work week.
At a party there were four large submarine sandwiches, all the same size. During the party, 2/3 of the chicken sandwhich, 3/4 of the tuna sandwhich, 7/12 of the roast beast and 5/6 of the veggie sandwhich were eaten. Which sandwhich had the least amount left?
Answer:
The answer is the Veggie Sandwich
Step-by-step explanation:
Given that there are four large submarine Sandwiches in a party and all of them are of the same size.
Some parts of each of them were eaten during the party. We are to find the Sandwich that has the least amount left.
The fractions of the Chicken Sandwich(C), Tuna Sandwich(T), Roast beef Sandwich(R) and the Veggie Sandwich(V) that were eaten during the party are given by
Therefore, the fractions of the Sandwiches that left will be
Out of the four fractions, V' is the smallest, so the Veggie Sandwich has the least amount left.
A number cube is rolled twice. What is the probability of getting a 6 on the first roll,
then a number less than 5 on the second roll?
A. 5/36
B. 1/9
C. 2/3
D. 1/36
Answer:
b. 1/9
Step-by-step explanation:
1. 1/6 is the probability of rolling 6
2. 4/6 is the probability of rolling less than 5
3. Multiply them: [tex]\frac{1}{6} x\frac{2}{3}[/tex]
4. Answer: 1/9
The probability of getting a 6 on the first roll, then a number less than 5 on the second roll should be option b.
Calculation of the probability:since
1/6 should be considered as the probability of rolling 6
And, 4/6 is the probability of rolling less than 5
So [tex]= 1\div 6 \times 2\div 3[/tex]
= 1/9
Hence, the option b is correct.

Given:
Perimeter of a parallelogram = 64 cm
Length = 3 times larger than the width
To find:
The length of the parallelogram.
Solution:
We know that, the perimeter of the parallelogram is:
[tex]P=2(l+w)[/tex]
Where, l is length and w is width of the parallelogram.
We have, l = 3w and P=64.
So,
[tex]64=2(3w+w)[/tex]
[tex]64=2(4w)[/tex]
[tex]64=8w[/tex]
Divide both sides by 8.
[tex]8=w[/tex]
Now,
[tex]l=3w[/tex]
[tex]l=3(8)[/tex]
[tex]l=24[/tex]
Therefore, the length of the parallelogram is 24 cm.

Answer: [tex]\frac{40}{3}\ \text{hours}[/tex]
Step-by-step explanation:
Nancy can do typing job in 8 hours
i.e. in 1-hour nancy can [tex]\frac{1}{8}[/tex] part of work
Together they can do that work in 5 hours
or in 1 hour [tex]\frac{1}{5}[/tex] part of work is done
suppose Carole takes x hours for the work

Answer:
(2, 2) ; (4, 4) ; (6, 6)
(4, 1) ; (4, 1) ; (8, 2) ; (12, 3)

Evaluating the ratio of each pair :
(1, 2) = 1/2 = 0.5
(2,3) = 2/3 = 0.67
(4, 7) = 4/7 = 0.57
(2,2) = 2/2 = 1
(4, 4) = 4/4 = 1
(6, 6) = 6/6 = 1
(3, 1) = 3 /1 = 3
(4, 1) = 4 / 1= 4

A unicycle tire can travel 7.85 ft. in on revolution. What is the area of the unicycle tire? Round answer to the nearest tenth.
Answer:
The answer would be 0.06
Step-by-step explanation:
Answer:
4.9ft^2
Step-by-step explanation:
7.85 ft is the circumference of the tire (circle), so [tex]\pi[/tex]d = 7.85.
7.85/[tex]\pi\\[/tex] = 2.5, the diameter is 2.5, so the radius is 1.25.
[tex]\pi[/tex]r^2 is the formula for the area, so [tex]\pi[/tex]*1.25^2 = 1.5625[tex]\pi[/tex], which is 4.906, which rounded to the tenth is 4.9.
