Answer:
The expression you can use to find out how many boys is b + (b - 84) = 1824
There are 954 boys at Southside High School
There are 870 girls at Southside High School
Step-by-step explanation:
Assume that the number of boys in the Southside High School is b
∵ There are b boys in the Southside High School
∵ The number of girls is 84 fewer than boys
→ Subtract 84 from b to find the number of girls
∴ The number of girls in the Southside High School is (b - 84)
∵ Southside High School has a total of 1824 students
→ That means the sum of the numbers of the boys and the girls is 1824
∴ b + (b - 84) = 1824
∴ The expression you can use to find out how many boys is
b + (b - 84) = 1824
→ Add the like terms in the left side
∴ (b + b) - 84 = 1824
∴ 2b - 84 = 1824
→ Add 84 to both sides
∵ 2b - 84 + 84 = 1824 + 84
∴ 2b = 1908
→ Divide both sides by 2 to find b
∵ [tex]\frac{2b}{2}=\frac{1908}{2}[/tex]
∴ b = 954
∴ There are 954 boys at Southside High School
∵ The number of girls at Southside High School = b -84
→ Substitute b by 954
∴ The number of girls at Southside High School = 954 - 84
∴ The number of girls at Southside High School = 870
∴ There are 870 girls at Southside High School

Answer:
Minimum, Vertex(1,-7) and sorry what do you mean by aos? i dont get that please type in the comments I'll answer that too. Hope you understand the rest
Step-by-step explanation:
The vertex of a parabola means the stationary point/turning point which is denoted by the following:
[tex]x=\frac{-b}{2a} \\[/tex]
and for y we just simply put the value of x that we get into the equation so lets get started
The equation [tex]y=x^2-2x-6[/tex] is a quadratic equation
and if we compare it by the standard form [tex]y=ax^2+bx+c[/tex] we get the following values
a=1 , b=-2 , c=-6
and now for the vertex
[tex]x=\frac{-b}{2a}[/tex]
[tex]x=\frac{-(-2)}{2(1)} \\x=\frac{2}{2} \\x=1[/tex]
and now for y
[tex]y=x^2-2x-6\\y=(1)^2-2(1)-6\\y=1-2-6\\y=-7[/tex]
so the vertex is (1,-7)
and the graph is minimum not maximum because the value of a is greater than 0 if the value of a>0 then the graph is minimum and if the value of a<0 meaning a is negative the graph is maximum and here in the equation a=1 which means a>0 then our graph is minimum.

what is the value of the expression below 5× (9-3)+7
Answer:
-23x.
Step-by-step explanation:
5x(9 - 3) +7.
5x times 9 = 45.
5x times -3 = -15.
45x - 15 +7.
45x - 15 = 30.
-30 + 7 = -23.
Hope this helps!

Find the size of unknown angles
Answer:
ok in this diagram we have two triangles the first triangle all angles are unknown the second triangle we have the values of two angles so we will start with the second triangle and as you know angles in a triangle add up to 180° so we will take 35 degrees + 30 degrees and name the unknown angle x is equals to 180 degrees so it will be 65 degrees + x is equals to 180° put the like terms together x will be equal to 180 degrees - 65 degrees it becomes a minus because when a plus crosses the equal sign it becomes - so x is equals to 115° and as you can see in the diagram 115° is vertically opposite z then you can extend the lines so as to understand the diagram better when you extend the lines you find that 35 degrees is equal to angle v so it will be 115 degrees + 35 degrees + x is equals to 180 degrees so 150° + x is equals to 180 degrees put the like times together x is equals to 180 degrees minus 150° x is equals to 30 degrees

Given the function f(x) = 7x + 2, find x when f(x) = 31.
0
Plz help
Answer:
x = [tex]\frac{29}{7}[/tex]
Step-by-step explanation:
Given f(x) = 7x + 2 and f(x) = 31 then equate the right sides
7x + 2 = 31 ( subtract 2 from both sides )
7x = 29 ( divide both sides by 7 )
x = [tex]\frac{29}{7}[/tex]

One of the angles formed by two intersecting lines measures 30°. What are the measures of the other three angles? i need help ASAP
Answer: The angles are 30 30, 150, 150
Step-by-step explanation: Two lines intersect means they cross. According to the vertical angle theorem, angles that are across are the same, a line is 180 degrees so it means the angles that make up the supplementary pair add up to 180(180-30=150). So there are 2 150 degree angles and 2 30 degree angles

evaluate the function for f(-3), f(x)=3x+5
Answer:
-4
Step-by-step explanation:
Since we know that -3 takes the place of x in f(x), we can sub in -3 for all x's in the equation.
Using this information, we now have F(-3)=3(-3)+5
Once you solve the right side of the equation, you get f(-3)=-4
if you were to plot this, the points would be (-3,-4), however I believe you're not trying to, so the answer would be -4.

Could you please help me with this question and explain it thoroughly?
Step-by-step explanation:
the answer is 50 because 2x-=76 is k :)
Answer:
k (oats in cups) = 25 (grams of almonds)
Step-by-step explanation:
If you look at the coordinates given in the question (1,k) where we are told to find k.
A coordinate is a pair of one x and y value, an input and output in a relationship.
2d coordinates are in the form of (x,y), this means that (1,k) is representing what k will be when x is 1. So to find k, we must look at where y (the amount of almonds in this instance) is when x (the oats) is 1.
This graph looks to be y = 25x.
Where y is the oats in cups, and x is the grams of almonds. This is a proportion which means that there are 25 grams of almonds for every 1 cup of oats.

I need help, marking as Brainliest.
Answer:
1)There has just been a dilation and translation of the first triangle to get to the second. Their hypotenuses have the same slope of +1.
2)There has just been a dilation since they are on about the same points of the line with a slope of 1 1/2.
3)They are related because they are both on the line with a slope of -3/2
4)Only a translation happened since they are the same size and are on the same line that has a slope of 2/3

Answer:
You need to solve it like a rectangle
Scale 1cm = 30Yd
Formula = A=lxw
Length = 7x30=210yd
Height = 4x30=120yd
Answer 120x210= 25,200 sq. yd.
Right, make sense?
Answer:
25200 square yards
Step-by-step explanation:
Reminder: the area of a parallelogram is its length times its height. In that case, it would be 4cm*7cm.
But you have to remember that 1 cm represents 30 yards, so you have to multiply everything by 30 first, and then solve:
4*30 yards * 7*30 yards
= 120 yards * 210 yards
= 25200 square yards.
