Answer:
20 students are girls. (15 are boys)
Step-by-step explanation:
if the ratio is 3:4 and the total students is 35, you can make the following equation:
3x + 4x = 35
7x = 35
x = 5
then, multiply x by 4.
5*4 = 20.
20 students are girls. (15 are boys.)

Find three consecutive integers such that when three times the third is increased by the first, the result is 8 less than five times the second.
Answer:
9, 10 and 11Step-by-step explanation:
x - the smallest of three consecutive integers (the first)
x+1 - the next of three consecutive integers (the second)
x+2 - the last of three consecutive integers (the third)
3(x+2) - three times the third integer
3(x+2)+x - three times the third increased by the first
5(x+1) - five times the second tnteger
5(x+1)-8 - 8 less than five times the second
3(x + 2) + x = 5(x + 1) - 8
3x + 6 + x = 5x + 5 - 8
4x + 6 = 5x - 3
-4x -4x
6 = x - 3
x = 9
x+1 = 10
x+2 = 11

Do the side lengths of 8, 15, and 20 form a triangle? Explain.
Can you explain how you did this
Yes; The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
The side lengths 8, 15, and 20 form the sides of a .triangle
In order to determine whether the length of the sides forms a triangle, we will use the theorem that states that:
The sum of any two sides of the triangle must be greater than the thirdGiven the side lengths 8, 15 and 20
Taking the sum of any two sides;
8 + 15 = 23
Since 23 > 20 (third side), this shows that the theorem is true
Similarly;
8 + 20 = 28Since 28 > 15 (third side), this shows that the theorem is trueAlso;
15 + 20 = 35Since 35 > 8 (third side), this shows that the theorem is trueSince all the conditions are met, hence the side lengths form a triangle.

To manage a rental property, a property manager charges $65 per month plus 6% of the rent.
If Jack pays the property manager $164 each month, what is the monthly rent on his property?
Given parameters:
Charge per month = $65
Percentage on rent= 6%
Amount paid by Jack per month = $164
Unknown:
Monthly rent on his property = ?
Solution:
Monthly rent on his property can be found by;
Amount paid by Jack per month = Charge per month + 6% of monthly rent
Let the monthly rent = x ;
So;
164 = 65 + [tex]\frac{6}{100} x[/tex] x
164 - 65 = [tex]\frac{6x}{100}[/tex]
99 = [tex]\frac{6x}{100}[/tex]
6x = 9900
x = 1650
Monthly rent on his property is $1650

Joseph and Wendy were catching tadpoles. At first Wendy caught nine times three more than Joseph caught. Joseph was upset and released half of Wendy 's tadpoles, and then six times as many as Joseph caught swam away. After all of this, Wendy only had three tadpoles left. How many tadpoles did Joseph catch?
Answer:
Joseph caught 7 tadpoles
Step-by-step explanation:
Let the number of tadpoles caught by Joseph be x
The number of tadpoles Wendy caught will be ;
9(x + 3)
After Joseph was upset, he released half of Wendy’s tadpole and then six times as many as Joseph caught swam away leaving Wendy with only three tadpoles left;
Hence, mathematically;
9(x + 3)/2 - 6x = 3
Multiply through be 2
9(x + 3) - 12x = 6
9x + 27 -12x = 6
9x -12x = 6-27
3x = 21
x = 21/3

Write an equation for the line that is parallel to the given line and passes through the given point . Write the equation of the line in y=mx+b form
y=5x-7;(2,-2)
A parallel line has the same slope as the original equation. Therefore, the slope (m in y=mx+b) will be 5. From there, we can use the point-slope formula and convert it into the slope-intercept formula (y=mx+b).
Point-slope is:
y-y₁=m(x-x₁)
Plug in our known values:
y-(-2)=5(x-(2))
Distribute and set it equal to y:
y+2=5x-10
y=5x-12

Step-by-step explanation:
angle a and b are supplementary angles. angle where a = 30+2x and b =x what is the measure of b degress
Answer:32 times 4 - 8 in degrees
Step-by-step explanation:
Since b = x, hence the value of b is 30 degrees
For two angles to be supplementary, the sum of the angles must be equal to 180 degrees
Given the angles
a = 30 + 2x
b = x
Equating the sum to 180
a + b = 180
30+2x + x = 180
30 + 3x = 180
3x = 180 - 30
3x = 150
x = 30 degrees
Since b = x, hence the value of b is 30 degrees

The resulting value for the given sum of trignometry identity is -2
Trigonometry identityTrigonometry identity are written in tems of sine, cosine and tangent
According to the trigonometry identity
sec theta = 1/costheta
cot theta = 1/tantheta
Given the trigonometry expression
sec 180 + sin 270 - tan 180 + cot 270
This can also be written as;
1/cos180 + sin270 - tan 180 + 1/tan270
