5t + 17 = 4( t +3 )
1/2x + 1/3x =10
1/4x + 2/5x = 39
please can someone help me with these problems i will give brainliest for the person who gives me the answers and work to go with it
Answer:
1. T = -5 2. X = 12 3. X = 60
Step-by-step explanation:
5t + 17 = 4(t + 3)
1. Distribute 4
5t + 17 = 4t + 12
2. Isolate the variable
t + 17 = 12
t = -5
1/2x + 1/3x = 10
1. Remove fractions by multiplying the equation by 6
3x + 2x = 60
2. Combine like terms
5x = 60
3. Divide by coefficient
x = 12
1/4x + 2/5x = 39
1. Remove fractions by multiplying by 20
5x + 8x = 780
2. Combine like terms
13x = 780
3. Divide by coefficient
x = 60

A team of biologists captured and tagged 65 deer in a forest. Two weeks later, the
biologists captured a sample of 30 deer from the same forest and found that 5 of
them were tagged. Which proportion could be used to estimate the number of deer in
the forest?
Answer:
1/6x= 65
Step-by-step explanation:
so we can assume that 5/10= 1/6 of the deer were tagged
lets call the total number of dear x
so 1/6x= 65
x= 380
The proportion that can be used to estimate the number of deer in the forest is 5/30 = 65/390
To estimate the number of deer in the forest, we can set up a proportion using the tagged deer in the sample as a representative of the entire population.
Let's denote the number of deer in the forest as 'x'.
We know that 65 deer were tagged out of the total population. In the sample of 30 deer, 5 were tagged.
Therefore, we can set up the following proportion:
Tagged deer in sample / Total deer in sample = Tagged deer in population / Total deer in population
5 / 30 = 65 / x
Now we can cross-multiply to solve for x:
5x = 65 * 30
5x = 1950
Dividing both sides by 5:
x = 1950 / 5
x = 390
Therefore, the proportion that can be used to estimate the number of deer in the forest is 5/30 = 65/390

In ΔGHI, h = 10 cm, ∠G=152° and ∠H=7°. Find the area of ΔGHI, to the nearest square centimeter.
Answer:
Step-by-step explanation:
I = 180-152-7 = 21°
Law of Sines:
g = h·sinG/sinH ≅ 38.5 cm
i = h·sinI/sinH = 29.4 cm
Use Heron's Formula to calculate the area from the lengths of the sides.
semi-perimeter s = (g+h+i)/2 ≅ 39.0 cm
area = [tex]\sqrt{s(s-g)(s-h)(s-i)}[/tex]≅ 69 cm²

Step-by-step explanation:
The rule gives the sequence ...
75, 69, 63, 57, 51, 45, ...
The 5th number in the sequence is 51.
__
Alternate solution
The equation for the general term of an arithmetic sequence is ...
an = a1 +d(n -1) . . . . . for first term a1 and common difference d
Your sequence has first term 75 and common difference -6, so the equation is ...
an = 75 -6(n -1)
Then for n=5, the term is ...
a5 = 75 -6(5 -4) = 75 -24 = 51
The 5th term is 51.

A store manager buys binoculars for $45 each. He marks up the cost by 40% to get the store price. Then the store has a sale and the store price is reduced by 10%. What is the sale price of the binoculars?
Answer:
$56.70
Step-by-step explanation:
The cost plus markup is found by multiplying $45 by 1.40: $63.
With the 10% price reduction, the sale price is 0.90($63) = $56.70.
Regarding 1.40: the '1' results in the full price to the manager plus the '0.40' markup.
