Answer:
d=1
Step-by-step explanation:
distribute 0.5 through the parentheses
3.5d+2=7-1.5d
move variable to the left-hand side and change its sign
3.5d+1.5d+2=7
move constant to the right-hand side and change its sign
3.5d+1.5d=7-2
collect all like terms
5d=7-2
subtract the numbers
5d=5
divide both sides
d=1

Answer:
x = 12
Step-by-step explanation:
[tex]\sqrt{3x}[/tex] + 10 = x + 4
[tex]\sqrt{3x}[/tex] = x - 6
( [tex]\sqrt{3x}[/tex] )² = ( x - 6 )²
3x = x² - 12x + 36
x² - 15x + 36 = 0
(x - 3)(x - 12) = 0
[tex]x_{1}[/tex] = 3
[tex]x_{2}[/tex] = 12
Check the answer:
[tex]\sqrt{3*3}[/tex] + 10 ≠ 3 + 4
13 ≠ 7 ⇒ 3 is not the root of original equation (strange root)
[tex]\sqrt{3*12}[/tex] + 10 = 12 + 4

Answer:
m∠4 = 57°
m∠5 = 123°
m∠6 = 35°
Step-by-step explanation:
m∠4 ≅ ∠57°
Therefore m∠4 = 57°
Following this rule of thumb
m∠6 ≅ 35°
m∠6 = 35°
m∠5 = 180 - 57
m∠5 = 123

Carlos worked 31.5 hours at a hospital as a volunteer. This represents 87.5% of his school’s requirement for community service. How many hours does the school require for community service?
Answers
Answer:
The answer to this question would be (to my best guess), 36 hours.
Step-by-step explanation:
First
You have to find the ratio between 87.5% and 100%. This is because you want to find what 100% represents.
To do this, you have to divide 100 by 87.5, which would represent 100 divided by 87.5. This will equal 1.142857142857143 , which isnt an easy number to work with.
Lastly
You have to multiply 1.142857142857143 by 31.5, because you reverse the previous operation, but the only difference is you swap out the percentages with the numbers they represent. This equals the final answer, which is 36, representing 36 hours.

Kayla's school is selling tickets to the annual dance competition. On the first day of ticket sales the school
sold 3 senior citizen tickets and 5 child tickets for a total of $70. The school took in $216 on the second day by
selling 12 senior citizen tickets and 12 child tickets. Find the price of a senior citizen ticket and the price of a
child ticket.
Answers
Answer:
senior ticket = $10 child's ticket = $8
Step-by-step explanation:
s = senior ticket
c = child's ticket
We need to write 2 equations, and we have 2 unknowns, s and c.
3s + 5c = $70
12s + 12c = $216
First solve for s using the first equation.
3s + 5c = 70 Subtract 5c from each side
3s + 5c - 5c = 70 - 5c
3s = 70 - 5c Divide each side by 3
3s/3 = (70 - 5c)/3
s = [tex]\frac{70 - 5c}{3}[/tex]
Now plug in s into the second equation.
12s + 12c = 216
12([tex]\frac{70 - 5c}{3}[/tex]) + 12c = 216
[tex]\frac{12}{3}[/tex] (70 - 5c) + 12c = 216
4 (70 - 5c) + 12c = 216
280 - 20c + 12c = 216
280 - 8c = 216 Add 8c to each side
280 - 8c + 8c = 216 + 8c
280 = 216 + 8c Subtract 216 from each side.
280 - 216 = 216 - 216 + 8c
280 - 216 = 8c
64 = 8c Divide each side by 8
64/8 = 8c/8
64/8 = c
8 = c
Now plug c into the first equation and solve for s.
3s + 5c = 70
3s + 5(8) = 70
3s + 40 = 70 Subtract 40 from each side.
3s + 40 - 40 = 70 - 40
3s = 70 - 40
3s = 30 Divide each side by 3
3s/3 = 30/3
s = 30/3
s = 10
So a senior ticket costs $10 and a child's ticket costs $8.

Answers
Answer:
a) How tall would the sunflower be after 10 weeks?
35 inches tall
Step-by-step explanation:
At the beginning of spring, Jeremiah planted a small sunflower in his backyard. When it was first planted, the sunflower was 15 inches tall. The sunflower then began to grow at a rate of 2 inches per week.
If the rate:
1 week = 2 inches
10 weeks = x inches
x = 10 × 2/1
x = 20 inches
How tall would the sunflower be after 10 weeks?
The initial height = 15 Inches
The height after 10 weeks =
15 inches + 20 inches
= 35 inches

A candle is lit and burns at a constant rate of change until it is completely burned. When the candle has been burning for 2.7 hours it is 14.3 inches tall and when it has been burning for 7.1 hours it is 4.2 inches tall. At what constant rate did the candle burn?
Answers
Answer:
2.29 inches/hour
Step-by-step explanation:
Given that the candle burns at a constant rate.
After time 2.7 hours, candle was 14.3 inches tall.
After time 7.1 hours, candle was 4.2 inches tall.
To find:
The constant rate at which the candle burn.
Solution:
Let the length be represented by [tex]l[/tex] and time be represented by [tex]t[/tex].
Let the constant rate be [tex]m[/tex].
and the initial length be [tex]L.[/tex]
The equation can be written as:
[tex]l =mt+L[/tex]
At [tex]t[/tex] = 2.7 hours , [tex]l[/tex] = 14.3 inches
[tex]14.3 =2.7m+L ..... (1)[/tex]
At [tex]t[/tex] = 7.1 hours , [tex]l[/tex] = 4.2 inches
[tex]4.2 =7.1m+L ..... (2)[/tex]
Equation (1) minus (2):
[tex]10.1=-4.4m\\\Rightarrow m = - 2.29\ inches/hour[/tex]
The candle burns at the rate of 2.29 inches/hour.

Malike rented a paddle boat at the park for a fixed charge of $2.50 plus $1.50 per hour. She want to stay out on the water as long as possible. How many hour can be use the boat without spending more than $7.00
Answers
Answer:
Malike can use the boat for 3 hours.
Step-by-step explanation:
$2.50 for renting the boat plus $1.50 per hour. 3 hours x $1.50 = $4.50 + the $2.50 = $7 flat
Malike can use the boat for 3 hours without spending more than $7.00
What is inequality?A statement of an order relationship-greater than, greater than or equal to, less than, less than or equal to- between two numbers or algebraic equations.
Now it is given that,
Fixed charge of boat = $2.50
Charge per hour = $1.50
Now let t be the total hours use by Malike.
Total charge in t hour = 1.50t
Total spending on boat = 2.50 + 1.50t
Since. She wants to spend not more than $7.00
⇒ 2.50 + 1.50t ≤ 7
Subtracting 2.5 both the side we get,
1.50t ≤ 7 - 2.5
⇒ 1.50t ≤ 4.5
Dividing both the side by 1.5 we get,
t ≤ 3
this is the total hours she can use the boat without spending more than $7.00
Thus, Malike can use the boat for 3 hours without spending more than $7.00
