Answer:
A. 6 ∙ (30 - 1)
Step-by-step explanation:
How can we re-write the expression below into “friendlier” terms? 6 ∙ 29
options:
A. 6 ∙ (30 - 1)
B. 6 ∙ (16 + 13)
C. 6 ∙ (19 + 10)
D. 6 ∙ (21 + 8)
Re-writing an expression in friendlier term means expressing the term using numbers that are closest to the expression.
Checking all options,
A. 6 ∙ (30 - 1)
Option A seems closer to 6 ∙ 29 because, 30 - 1 which is very easy to evaluate gives 29
Moreover, 29 is very close to 30
Compared to other options, which have values that requires more thinking in evaluation

Answer:
9 hours
Step-by-step explanation:
Jan's speed=70 mph
Jo's speed =60 mph
distance between =1170
relative speed=70+60=130
time taken for them to meet will be:
time=(distance)/(relative speed)
=1170/130
=9 hours

A. 8(3 + 9)
B. 8(3 + 1)
C. 3(4 + 3)
D. 3(8 + 3)
Step-by-step explanation:
the answer is D
this is because, 24 + 9 = 33
and (3×8 + 3×3 =33)
Answer:
the answer is D 3 times(8+3)=(24+9)

Which inequality is represented by this graph?
Answer: C
Step-by-step explanation:
A sequence can be generated by using fn = 2f(n-1)+1, where f1 = 4 and n is a whole number greater than 1. What are the first four terms in the sequence?
Answer:
{9,19,39,79}
Step-by-step explanation:
Recursive Sequences
The recursive sequence can be identified because each term is given as a function of one or more of the previous terms. Being n an integer greater than 1, then:
f(n) = 2f(n-1)+1
f(1) = 4
To find the first four terms of the sequence, we set n to the values {2,3,4,5}
For n=2f(2) = 2f(1)+1
Since f(1)=4:
f(2) = 2*4+1
f(2) = 9
For n=3f(3) = 2f(2)+1
Since f(2)=9:
f(3) = 2*9+1
f(3) = 19
For n=4f(4) = 2f(3)+1
Since f(3)=19:
f(4) = 2*19+1
f(4) = 39
For n=5f(5) = 2f(4)+1
Since f(4)=39:
f(5) = 2*39+1
f(5) = 79

The aspect ratio of a television or movie
screen is the ratio of the width of the screen
to its height. A high-definition television
has an aspect ratio of 16:9. The movie
Star Wars was filmed in cinemascope,
which has an aspect ratio of 2.35:1. Are
these aspect ratios equivalent? Explain.
Hellppp
Answer:
The aspect ratios of both are not same
Step-by-step explanation:
Here, we want to check if the given ratios are equivalent.
So what we want to do here is to check if 16/9 is equivalent to 2.35:1
Mathematically; 16/9 is same as 1.78/1
We can see that 1.78/1 is not same as 2.35/1
Hence, the aspect ratios of both are not the same thing

suppose you are buying two kinds of chips for a party. Each bag of potato chips cost $2.50 and each bag of corn chips cost $2.90. You must have at least 100 bags of chips for the party and the total cost of the chips can be no more than $350
Part A:Write a system of two inequalities that describe the situation
Part B: Write one possible solution to the problem in sentence form
Answer:
At least means ≥
No more than means ≤
Let x = number of bags of potato chips
Let y = the number of bags of corn chips
x+y≥100
2.50x+2.90y≤$350
Let's try x=80 and y=20 (We know that is equals 100 so it will work for the first equation
2.50(80)+2.90(20) = 258 which is ≤$350
Buy 80 bags of potato chips and 20 bags of corn chips is one possibility.

Solve the equation 4.1g+6=2.1g+12.
a. Find the value of g.
b. Explain how you can check that the value you found for g is correct. If your check does not work, does that mean that your result is incorrect? Explain.
a. g=
Answer:
g=3
Step-by-step explanation:
The value of g is 3 and it is correct when checked by substituting g=3 into the equation.
Given:
4.1g + 6 = 2.1g + 12
collect like terms
4.1g - 2.1g = 12 - 6
2g = 6
divide both sides by 2
g = 6 / 2
g = 3
Check:
4.1g + 6 = 2.1g + 12
4.1(3) + 6 = 2.1(3) + 12
12.3 + 6 = 6.3 + 12
18.3 = 18.3
Therefore,
The value of g is 3 and it is correct when checked by substituting g=3 into the equation.
