Answer: X = 11/5
Step-by-step explanation: Put it in standard form first!!
simplify -2 + 4x = 9 - x
regroup items 4x - 2 = 9 - x
Add two on both sides 4x = 9 - x + 2
simplify 9 - x + 2 to 11 - x
4x = 11 - x
Add x to both sides 4x + x = 11
Simplify 4x + x to 5x
5x = 11
divide both sides by 5
x = 11/5
Ann thought of a number N, multiplied it by 5 and added 7. Then she told the result R to Jim.
a) Find the domain and the range of this function.
b) Draw a graph that shows how R depends on N
c) Write a formula that will tell you the value of R for any value of N.
d) Using the previous formula, write the formula that could help Jim guess Anne's number N
<span>Total households = 127,900,000
Proportion of households having remote control and not
7 : 3
7x + 3x = 127,900,000
10x = 127,900,000
x = 12,790,000
Households having remote control = 7x
= 7 X 12,790,000
= 89,530,000
Answer:
89,530,000 households have TV remote controls.</span>
Answer: Number of bags of 8. = 33
Number of bags of 10. = 31
Step-by-step explanation:
Let x = Number of bags of 8.
y = Number of bags of 10.
As per given.
(i)
(ii)
Put value of x from (ii) in (i)
Put this in (i), x= 31+2=33
Hence,
Number of bags of 8. = 33
Number of bags of 10. = 31
Answer:
UNLIKELY
Step-by-step explanation:
Given that:
Probability of rolling a six with a six sided nuner cube = 1/6
Required outcome / Total possible outcomes
Number of 6 / total sides of number cube = 1/6
The probability value obtained shows that there is a chance of getting a six ; however it is possible at about once in every 6 rolls of the dice.
Hence getting a six isn't impossible but the chance is small. A probability of 1/6 is the smallest that can be obtained for any of each number on the dice. Hence, it could be said that the likelihood is 'UNLIKELY'
