Answer:
Distribute, then combine like terms, subtract 10 from both sides of the equation, simplify, divide both sides of the equation by the same term, and simplify to get your solution.
Step-by-step explanation:
1.) Distribute
6−2(4−5)=40
6−8+10=40
2.) Combine like terms
6a-8a+10=40
-2a+10=40
3.) Subtract 10 from both sides of the equation
-2a+10=40
-2a+10-10=40-10
4.) Simplify
subtract the numbers
-2a+10-10=40-10
-2a=40-10
subtract the numbers
-2a=40-10
-2a=30
-2a=30
5.) Divide both sides of the equation by the same term
-2a=30
[tex]\frac{-2a}{-2} =\frac{30}{-2}[/tex]
6.) Simplify
cancel terms that are in both the numerator or denominator
[tex]\frac{-2a}{-2} =\frac{30}{-2}[/tex]
a=[tex]\frac{30}{-2}[/tex]
Divide the numbers
a=[tex]\frac{30}{-2}[/tex]
a=-15
a=-15
7.) Solution
a=-15

In a study a researcher measured a plant to be 8 cm tall. If the plant continues to grow 2 cm every week, after how many weeks will the plant reach the height of 24 cm?
Answer:
8 weeks
Step-by-step explanation:
Given
[tex]Initial\ Height = 8cm[/tex]
[tex]Growth = 2cm[/tex] weekly
Required
Determine the duration it gets to 24 weeks
First, we need to represent the scenario as a function.
Let the number of weeks be w.
So:
f(w) = Initial Height + Growth * Number of Weeks
This gives:
[tex]f(w) = 8 + 2 * w[/tex]
[tex]f(w) = 8 + 2w[/tex]
When the duration is 24 weeks,
We have that:
[tex]f(w) = 24[/tex]
Substitute 24 for f(w)
[tex]24 = 8 + 2w[/tex]
Make 2w the subject of formula
[tex]2w = 24 - 8[/tex]
[tex]2w = 16[/tex]
Make w the subject of formula
[tex]w = 16/2[/tex]
[tex]w = 8[/tex]
Hence, it'll take the plant 8 weeks to get to 24cm
Find the number that if subtracted from 7 and 12, the product of the two numbers gives 104
6 is the number i think that
-1 is the number that if subtracted from 7 and 12, the product of the two numbers gives 104
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
We need to find the number that if subtracted from 7 and 12, the product of the two numbers gives 104
We need to find two integer factors of the number 104 that multiply up 104 and differ by 12-7 = 5 units
104=2×52
104=4×26
104=8×13
If we consider the unknown number as (-1) then
number that if subtracted from 7
7-(-1)=8
number that if subtracted from 12
12-(-1))=13
8×13=104
Hence -1 is the number that if subtracted from 7 and 12, the product of the two numbers gives 104.

A large jar contains a mixture of white and black beans. In a randomly chosen handful of 120 beans 40 were black. Create a 98% confidence interval for the proportion of black beans in the jar. Express your answer to the nearest percent.
Answer:
23%<x<43%
Step-by-step explanation:
The formula for calculating confidence interval is expressed;
Confidence Interval = p ± z√p(1-p)/n
n is the sample size
z is the z score at 98% confidence interval
n is the sample size = 120
z = 2.33
If in a randomly chosen handful of 120 beans 40 were black, then;
p = 40/120
p = 4/12
p = 0.33
CI = 0.33± 2.33√0.33(1-0.33)/120
CI = 0.33± [2.33√0.33(0.67)/120]
CI = 0.33± [2.33√0.2211/120]
CI = 0.33± [2.33(0.04292)]
CI = 0.33±0.100014
CI = (0.33-0.100014, 0.33+0.100014)
CI = (0.229, 0.430014)
CI = (22.9, 43.0014)
Hence 98% confidence interval for the proportion of black beans in the jar is 23%<x<43%.
How do you do this question?
Answer: B) Demand will most likely be elastic
Place yourself in the shoes of the employer. To them, demand is them needing/wanting workers. Specifically we call this "labor demand". The supply is the potential or current worker providing the service and/or making the product.
If the price goes up, then this means the worker earns higher wages. This in turn causes labor demand to fall. So the employer will be less likely to hire more workers if the wages increase. It's similar to how if the price of an item goes up in a store, then less people are probably going to buy it.
Demand is elastic because a small change in price causes a large change in demand. The company is going to be sensitive to wage changes. The company sees that it is approaching the diminishing returns, so it is likely to scale back on labor to save costs. It's all about trying to minimize costs and maximize revenue. Often, revenues can't be changed very much since customers are themselves sensitive to price changes (assuming there are substitutes in the market), so the company will turn to trying to reduce costs as much as possible leading to maximum profit.

Carla is following a recipe that calls for a cinnamon-sugar mixture that is 5% cinnamon.
If she places 2 grams of cinnamon in a bowl, which equation will help her find how many grams of sugar to add to the bowl?
Answer:
Step-by-step explanation:
It's a proportion rather than an equation that you might be more accustomed to.
2/0.05 = x/ 0.95 Cross multiply
2 * 0.95 = x * 0.05 Divide by 0.05
2 * 0.95/0.05 = x
x = 38 grams of sugar should be added to the 2 grams of cinnamon.
There's another way to do it.
2/0.05 = (x + 2)/1 Cross multiply
2*1 = 0.05x + 0.1 Subtract 0.1 from both sides
1.9 = 0.05x
1.9/0.05 = x
x = 38
