7. Is 5.787787778... a rational or irrational number?
Explain.
Answer:
Rational ...................
Step-by-step explanation:
A rational number is a number that can be express as the ratio of two integers. A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number
What is the product of 3x+4 and 6x^{2} −5x+7?
[tex](3x + 4)(6 {x}^{2} - 5x + 7) \\ = 18 {x}^{3} - 15 {x}^{2} + 21x + 24 {x}^{2} - 20x + 28 \\ = 18 {x}^{3} + 9 {x}^{2} + x + 28[/tex]

find the value of x and y
Answer:
x=11
y=3
Step-by-step explanation:
(9x+25)=(13x-19)
9x+25 = 13x−19
9x+25-25 = 13x−19-25
9x=13x-44
9x-13x=13x-44-13x
-4x= -44
x=11
y= 180-(9x+25)
y= 180-(99+25)
y= 180-124 = 56
y= 56-5 = 51
y= 51/17
y= 3

Give the next 2 terms in this sequence. 1/8 ; 2/7 ; 1/2 ; 4/5
Answer:
5/4, 2Step-by-step explanation:
Given sequence:
1/8, 2/7, 1/2, 4/5Rewrite as:
1/8, 2/7, 3/6, 4/5We observe the numerators: 1, 2, 3, 4 and denominators: 8, 7, 6, 5
The next two terms are:
5/4 and 6/3or
5/4 and 2Recreate
1/8,2/7,3/6,4/5We can see
The denominator is decreasing by 1 and numerator is increasing by 1
So next term
(4+1)/5-15/4Next term
(5+1)/4-16/32help me pls i don't understand the problem so can u give me the answers and also explain
Step-by-step explanation:
1)
[tex]\frac{2}{3} +\frac{4}{5} =\frac{10+12}{15}=\frac{22}{15} .[/tex]
2) the same value of the denominator of the fractions.
3) 4²*2²=16*4=64 or 4²*2²=(4*2)²=8²=64.
Megan's answer is correct.
4) if the given length is 2,25=9/4 (feet), then the length of each piece is 9/4 :3=3/4=0.75 (feet) or 3/4*12=9 (inches).
5) a. 4-6= -2; b. -4+6=2; c. -4-6= -10, so the required order is c<a<b.
6) A. -8+3= -5; B. -8*3= -24, so the greater value is (-5) - answer A.
7) if to calculate every option, then A. 2.3*6.5=14.95; B. 21.45-6.5=14.95; C. 8.32+6.63=14.95, - all of them are equal.
Which of the following means the same as 2(3x – 4) ?

Step-by-step explanation:
13) LCM of 20 , 5 is 20
Find equivalent fraction for 2/5 with denominator 20
[tex]\dfrac{2}{5}=\dfrac{2*4}{5*4}=\dfrac{8}{20}[/tex]
Now compare
[tex]\dfrac{7}{20} \ < \dfrac{8}{20}\\\\\dfrac{7}{20} \ < \dfrac{2}{5}[/tex]
14) Convert fraction to decimal
[tex]\dfrac{1}{8}= 0.125[/tex]
0.15 > 0.125
[tex]0.15 \ > \dfrac{1}{8}[/tex]

help me solve these please. Im in integrated math 2
Answer:
1.
[tex] \frac{2}{5} = \frac{x}{15} \\ \\ 5x = 2 \times 15 \\ 5x =30 \\ x = \frac{30}{5} \\ x = 6[/tex]
2.
[tex] \frac{4}{3} = \frac{x}{7} \\ 3x = 4 \times 7 \\ 3x = 28 \\ x = \frac{28}{3} \\ x = 9.33 [/tex]
3.
[tex] \frac{7}{5} = \frac{28}{x} \\ 7x = 5 \times 28 \\ 7x = 140 \\ x = \frac{140}{7} \\ x = 20[/tex]
4.
[tex] \frac{11}{4} = \frac{5}{x} \\ 11x = 5 \times 4 \\ 11x = 20 \\ x = \frac{20}{11} \\ x = 1.8[/tex]
