answer this equation-3x+2<8
Answer:
x > -2
Step-by-step explanation:
-3x+2<8
Subtract 2 from each side
-3x+2-2<8-2
-3x<6
Divide each side by -3, remembering to flip the inequality
-3x/-3 > 6/-3
x > -2
Hey there!☺
[tex]Answer:\boxed{x>-2}[/tex]
[tex]Explanation:[/tex]
[tex]-3x+2<8[/tex]
Let's subtract 2 from both sides of the inequality.
[tex]-3x+2-2<8-2\\-3x<6[/tex]
Now divide both sides by -3.
[tex]\frac{-3x}{-3}<\frac{6}{-3}[/tex]
Simplify 6/-3. Also remember that dividing a positive with a negative will give us a negative.
[tex]6/-3=-2[/tex]

Jasmine spends exactly £120 on three types of plants: poisoned ivy, deadly nightshade and triffids. Poisoned ivy plants cost £2 each, deadly nightshade plants cost £9 each and triffids cost £12 each. She buys twenty plants in total, including at least one of each type. How many triffids did she buy?
Answer:
9/5
Step-by-step explanation:
2×9×12=216 so216/120 =9/5
Jasmine bought approximately 4 triffids.
We have,
We know that Jasmine bought a total of twenty plants and that she purchased at least one of each type.
Let's assume she bought x triffids.
From the given information, we can determine the number of poison ivy plants and deadly nightshade plants she bought:
Number of poisoned ivy plants = Total plants - (Number of deadly nightshade plants + Number of triffids)
Number of poisoned ivy plants = 20 - (1 + x) = 19 - x
Number of deadly nightshade plants = Total plants - (Number of poisoned ivy plants + Number of triffids)
Number of deadly nightshade plants = 20 - (1 + (19 - x)) = 20 - (20 - x) = x
We can now set up an equation based on the total amount Jasmine spent:
Total cost = (Number of poisoned ivy plants * Cost per poisoned ivy plant) + (Number of deadly nightshade plants * Cost per deadly nightshade plant) + (Number of triffids * Cost per triffid)
£120 = (19 - x) * £2 + x * £9 + x * £12
Simplifying the equation:
£120 = £38 - £2x + £9x + £12x
£120 = £38 + £19x
£82 = £19x
Dividing both sides of the equation by £19:
£82/£19 = x
x ≈ 4.32
Since we can't have a fractional number of plants, we'll round down to the nearest whole number.
Therefore,
Jasmine bought approximately 4 triffids.

Approximately how many times greater is 2.3x10^-4 than 1.15x10^-8?
Answer:
2.3 × is 20,000 times greater than 1.15 ×
Step-by-step explanation:
Given as :
The first number= x = 2.3 ×
The second number= y = 1.15 ×
Let The first number is z times greater than second number
i.e x = z × y
Or, z =
Or, z =
Or, z = 2 ×
∴ z = 20,000
So,The first number is 20,000 times greater than second number
Hence, 2.3 × is 20,000 times greater than 1.15 ×

Which equation represents a function? Select all that apply.
In a social club, the ratio of men to women is 5: 7. There are 595 women. How
many men are there?
Answer:
52
you take 5 ÷ it by 7 the ×it by 595
A ratio is an ordered pair of numbers a and b written as a/b where b is not equal to zero.
if the number of women in the social club is 595 then the number of men in the social club is 425.
What are ratios and proportions?A ratio is an ordered pair of numbers a and b written as:
a / b where b does not equal 0.
A proportion is an equation in which two ratios are equal to each other.
We have,
The ratio of men to women:
= 5:7
= 5/7
Let,
The number of men = 5x
The number of women = 7x
Now,
If the number of women = 595
We have,
7x = 595
Multiplying both sides by 5/7 we get,
5/7 x (7x) = 5/7 x 595
5x = 5/7 x 595
5x = 5 x 85
5x = 425
This means if there are 435 men in the social club if the number of women is 595.
Thus if the number of women in the social club is 595 then the number of men in the social club is 425.
