Answer:
11.5
Step-by-step explanation:
Find new values:
140(1+0.05)=147
68(1+0.25)=85
Last Year This Year
Boys 140 147
Girls 68 85
Total 208 232
Find overall increase:
208(1+r)=232
1+r=1.115385
r=0.115385
Final Answer: 11.5%
The total number of students on the honor roll increased by 11.5%.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
The percentage increase in the number of boys on the honor roll is 5%, which means that the number of boys on the honor roll this year is 1.05 times the number of boys on the honor roll last year:
1.05 x 140 = 147
The percentage increase in the number of girls on the honor roll is 25%, which means that the number of girls on the honor roll this year is 1.25 times the number of girls on the honor roll last year:
1.25 x 68 = 85
Therefore, the total number of students on the honor roll this year is:
147 + 85 = 232
The percentage increase in the total number of students on the honor roll is:
((232 - 208) / 208) x 100% = 11.5385%
Rounding to the nearest tenth gives an answer of 11.5%.
Therefore, the total number of students on the honor roll increased by 11.5%.

What is the slope of a line perpendicular to the line y = −14x – 1?
Answer:
m = ¹/₁₄Step-by-step explanation:
y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇔ m₁×m₂ = -1
{Two lines are perpendicular if the product of theirs slopes is equal -1}
y = -14x - 1 ⇒ m₁ = -14
-14×m₂ = -1 ⇒ m₂ = ¹/₁₄
So, the slope of a line perpendicular to the line y = -14x - 1 is m = ¹/₁₄

Solve the System by Substitution:
y = x-2
x + y = 4
Answer:
x=3
y=1
Step-by-step explanation:
We know that y is basically two less than x, so we can plug that into the second equation:
x+ (x-2) = 4
We can now simplify:
2x-2=4
2x=6
x=3
After finding x we can now find y with any equation (both work):
y= 3-2
y=1
Hope this helped!
Answer:
x = 3, y = 1Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.

Step-by-step explanation:
20% of 260 students at hill middle school ride a bus to school. how many students ride a bus to school?
Answer:
52 students ride a bus to school
Step-by-step explanation:
Step 1: Our output value is 260.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above $260 = 100%.
Step 4: Similarly, x = 20%.
Step 5: This results in a pair of simple equations:
260 = 100%(1).
x = 20%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
[tex]\frac{260}{x}[/tex] = [tex]\frac{100}{20}[/tex]%
Step 7: Again, the reciprocal of both sides gives
[tex]\frac{x}{260}[/tex] = [tex]\frac{20}{100}[/tex]
⇒x=52$
Therefore, 20% of 260 is 52.
Hope this helps! :)

The number of students who ride a bus is 52.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Total number of students = 260
The number of students who ride a bus.
= 20% of 260
= 1/5 x 260
= 52
Thus,
The number of students who ride a bus is 52.

The slope between (8, 10) and (14, -5) will be:
[tex]m=-\frac{5}{2}[/tex]Step-by-step explanation:
Given the points
(8, 10)(14, -5)Finding the slope between (8, 10) and (14, -5)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(8,\:10\right),\:\left(x_2,\:y_2\right)=\left(14,\:-5\right)[/tex]
[tex]m=\frac{-5-10}{14-8}[/tex]
[tex]m=-\frac{5}{2}[/tex]
Therefore, the slope between (8, 10) and (14, -5) will be:
[tex]m=-\frac{5}{2}[/tex]Rearrange x = 3g + 2 to make g the subject g=?
Step-by-step explanation:
x=3g+2
you need to move the equation to the other side, first you'd start with the one furtherest from g, which is is 2.
x = 3g
-2. - 2
and minus it from both sides
x-2=3g
3g is like 3x, which is 3 times x and you need to use the opposite operators so times would become divide.
so now it becomes x-2 over 3=g
