Answer:
factoring out the 1/2 (that is the coefficient of the variable) would require you to divide the equation by one half, which is the same as multiplying by two. After doing this, the answer can be expressed as:
1/2 (d+12)
Step-by-step explanation:
Answer:
Step-by-step explanation:
Factor out a 1/2
[tex]\frac{1}{2}(d+12)[/tex]
Redistribute if you want to check your work
[tex]\frac{d}{2}+\frac{12}{2} =\frac{1}{2}d+6[/tex]

- 5x + 2y = 9
y = 7x
Answer:
x = 1Explanation:
- 5x + 2y = 9
y = 7xInsert 7x For 'y'- 5x + 2(7x) = 9
Remove Parenthesis-5x + 2 · 7x = 9
Multiply: 2 · 7 = 14-5x + 14x = 9
Add: -5x + 14x = 9x9x = 9
Divide Both Sides By 99x ÷ 9 = 9 ÷ 9
x = 1The number of years it will take for $510 to grow to $1,010.18 at 5 percent compounded annually is ____
Answer:
13.66 years
Step-by-step explanation:
Given data
P=$510
A=$1,010.18
R=5%
t= ln(A/P)/r
susbstitute
t= ln(1,010.18/510)/0.05
t=ln1.980/0.05
t= 0.683/0.05
t= 13.66
Hence the time is 13.66 years
Please help!! I will make you brainlest.
Answer:
Step-by-step explanation:
These problems are based on triangle ratios. You cannot use the Pythagorean theorem to solve them.
The first triangle is a 45 45 90 degree triangle (I'm talking about the angles), and so, the ratio is 1:1:[tex]\sqrt{2\\}[/tex], so I have to divide the hypotenuse by [tex]\sqrt{2\\}[/tex] to get the legs. The hypotenuse is 15[tex]\sqrt{6}[/tex], so that divided by [tex]\sqrt{2\\}[/tex] is 15[tex]\sqrt{3\\}[/tex]. X is the same length as y because of the triangle ratio, so both x and y for the first triangle are 15[tex]\sqrt{3\\}[/tex].
The second triangle is a 30 60 90 degree triangle, so the ratio is x:x[tex]\sqrt{3}[/tex]:2x. The short leg is 7[tex]\sqrt{3}[/tex], so 7[tex]\sqrt{3}[/tex] * 2 is the hypotenuse, which is 14[tex]\sqrt{3}[/tex]. The long leg is 7[tex]\sqrt{3}[/tex] * [tex]\sqrt{3}[/tex], which is 21. So, x for the second triangle is 14[tex]\sqrt{3}[/tex], and y for the second triangle is 21.
Answer:
Question 9: x = [tex]15\sqrt{3}[/tex], Question 10: y = [tex]15\sqrt{3}[/tex], Question 11: x = [tex]14\sqrt{3}[/tex], Question 12: y = 21
Step-by-step explanation:
Question 9-10: Right triangles with 45°, 45°, 90° have a special rule, the legs of the triangle are equal, so x = y. Now you can form the statement [tex]2x^2 = 1350[/tex], and because x = [tex]15\sqrt{3}[/tex], so does y.
Question 11-12: Right triangles with 30°, 60°, 90° also have a special rule, the side corresponding to 30° is half the length of the hypotenuse and the side corresponding to 60° is [tex]\sqrt{3}[/tex] times as great as the 60°. x is 2 times as big as [tex]7\sqrt{3}[/tex], so its length is [tex]14\sqrt{3}[/tex]. Y is [tex]\sqrt{3}[/tex] as great as [tex]7\sqrt{3}[/tex], so its length is 21.

Answer:
4. supplementary
5. complementary
Step-by-step explanation:
4 is supplementary because the sum of the two angles is 180°.
5 is complementary because the sum of the two angles is 90°.
Answer:
4. Supplementary
Supplementary angles sum up to 180 degrees.
105 degrees + 75 degrees = 180 degrees
5. Complementary
Complementary angles sum up to 90 degrees.
30 degrees + 60 degrees = 90 degrees
Hope this helps, thank you !!

16. Hanna has a bag of 23 marbles. 5 marbles are red, 6 marbles are blue, and the rest
are pink. Abby takes out two pink marbles without replacing them. What is the
probability that the next marble he draws will be blue?
A. 10/21
B. 4/21
C. 2/7
D. 6/23
Answer:
C. 2/7
Step-by-step explanation:
When two pink marbles are taken without replacement then the total number of marbles in the bag are reduced to 21 marbles. So the blue marble, which are currently in total 6 marbles, is taken out of the total of 21 marbles. The calculation of which is done as below:
Probability of Next Marble to be blue
= Blue Marble / Total Marbles in the bag
= 6 / 21
= 2 / 7
Hence, the correct option is C. 2/7

Question 15
3a + 2 + 3a + 7so 3a+3a= 6a and 7+2=9
so you have to add the ones that are similar but never add

angle 9 and angle 10 are corresponding and complementary angles formed by two parallel lines cut by a transversal. find m angle 9
Answer:
45 degrees
Step-by-step explanation:
if <9 and <10 are corresponding, it means they are equal i.e <9 = <10
Since <9 and <10 are also complementary angles, their sum will be 90 degrees
<9+<10 = 90
<9 + <9 = 90
2m<9 = 90
m<2 = 90/2
m<2 = 45 degrees
Hence the measure of angle 9 is 45 degrees

Find the circumference of each circle. Use your calculator's value of p. Round your answer to the nearest tenth.
please helppppppppppppppppppppp
Answer: The circumference is 33.284 cm
Step-by-step explanation:
The equation to find the circumference use the fomula to find it.
3.14 is the simplified version of Pi (I SUGGEST TO USE YOUR CALCULATOR)
C = 2*pi*R /// Circumference = 2 times pi times Radius.
C = 2 * 3.14 * 5.3
C = 6.28 * 5.3
C = 33.284

Answer:
For 17 the first answer is 1(1/20). The picture can be misleading because the flags are at the same height and the American flag's pole looks shorter. This is only because it is behind the Floridian flag and because the perspective isn't accurate to compare them.
Step-by-step explanation:
The mixed fraction would be 1(5/100) which can be simplified when you divide the fraction by 5 into 1(1/20).

Slope is –2, and (5, 3) is on the line.
To be put into slope intercept form
i wish that i could help you but I just dont understand it... I am sorry
Answer: putting that in slope intercept form : y=-2x+10
Step-by-step explanation:
slope intercept form is y=mx+b.
m= the slope
the slope you gave us is -2
b= the y intercept
a y intercept is the coordinate that touches/crosses the y axis.
to find the y intercept, use the slope (rise over run) you will eventually cross the y axis at 10.
y=-2x+10
i think.

93 is the sum of a number g and 58.
Answer:
G is 35.
Step-by-step explanation:
You can make the equation 93 = g + 58. In order to find the variable g, you have to isolate it. So you can subtract 93 by 58 and you get 35. To double check your work, just plug in your answer in g.
93 = 35 + 58
93 = 93 ✔️
The answer is 35.
