Answer:
Heather served 10 orders.
Felipe served 30 orders.
Jim served 50 orders.
What we know:
Let's refer to each person by their first initial (H, J, & F)
H + J + F = 90
F = 3 * H
J = 5 * H
Substitution:
Let's replace F and J by their equivalents in relation to H (basically making the entire left side only H)
H + (5 * H) + (3 * H) = 90
H + (5H) + (3H) = 90
9H = 90
H = 90/9
H = 10
Final Calculations
Now that we know how many orders Heather served, we can calculate how many Jim and Felipe served
F = 3 * H
F = 3 * 10
F = 30
J = 5 * H
J = 5 * 10
J = 50

Whats the slope of the line?
Answer:
m = rise/run = 4/5.
Step-by-step explanation:
This line goes throught the "exact" grid intersections (-2, 0) and (3, 4). As we move from the first point to the second, we see that x increases by 5 (this is the 'run') and y increases by 4 (this is the 'rise'). Thus, the slope of this line is m = rise/run = 4/5.

Which factored polynomial is shown in the graph?
A) y = (x + 2)(x + 1)(x + 4)
B) y = (x + 2)(x − 1)(x + 4)
C) y = (x + 2)(x − 1)(x − 4)
D) y = (x − 2)(x − 1)(x + 4)
Answer:
B
Step-by-step explanation:
First, we can determine the zeros of the function.
We can see that the graph passes through the x-axis at the points: x = -4, -2, and 1.
Therefore, we have three factors:
[tex](x-(-4)),\, (x-(-2))\text{ and } (x-(1))[/tex]
Thus, our function will be:
[tex]y=(x+4)(x+2)(x-1)[/tex]
Our answer is B.

Can someone help me I don't know what n represents
Answer:
n=7
Step-by-step explanation:
6(n-3) - 2n=10
Distribute
6n - 18 -2n = 10
Combine like terms
4n -18 = 10
Add 18 to each side
4n-18+18 = 10+18
4n = 28
Divide by 4
4n/4 = 28/4
n = 7

Mark me brainliest if I'm right :)
i do t really know how to do this pls help
Answer:
for number 5 Subtract 18 from both sides of the equation
4+18−18=30−18
for number 1 Subtract 7 from both sides of the equation
so number 3 subtract 3 from each side and so on hope it helps
im not sure how to explain it but--
for example.. the first one
1) y + 7 = 12
first, you subtract 7 from both sides
so-- you'll subtract 7-7 on the left and 12-7 from the right
now, you have y by itself since 7-7 = 0
y = 12-7, or y = 5
also its important to note that when the equation is like 2) and uses subtraction (x-4) instead of addition (y +7)-- then you add to both sides
so for 2)-- you'd add 4 to both sides for 4 to cancel out to equal 0
your goal is always to isolate the variable on one side

In a regular tessellation 3,4,6 sides can be tessellating regular
polygon.
What is regular polygon?A normal tessellation is one made the use of only one regular polygon. A semi-normal tessellation uses or extra ordinary polygons. Triangles and squares, for example, shape ordinary tessellations and octagons and squares for a semi-normal tessellation.
First of all, there are handiest 3 normal tessellations which can be triangles, squares, and hexagons. To make a ordinary tessellation, the inner angle of the polygon has to be a diviser. that is due to the fact the angles need to be introduced as much as so it does now not leave any gaps.
A polygon having identical facets of identical lengths are known as everyday polygons. A ordinary polygon is a polygon that is equiangular i.e. all the angles are equal in measure and equilateral i.e. all facets have the equal length.
A line of symmetry is a line that can be attracted to divide a parent into same halves. A determine has line symmetry or reflection symmetry while it could be divided into identical halves that match. A discern has mirrored image symmetry if it could be meditated throughout a line and look exactly the same as it did earlier than the reflection.

Answer:
Midpoint is[tex](-25.15,10.2)[/tex]
Step-by-step explanation:
A line segment refers to line that has two endpoints.
Let [tex](a,b),(c,d)[/tex] be the endpoints of a line segment.
Midpoint of the line segment is given by [tex](\frac{a+c}{2} ,\frac{b+d}{2})[/tex]

In Frank's piggy bank, there are only quarters
and dimes. He has 37 coins, and has a total of
$5.50. How many quarters does he have?
Answer:
12 quarters
Step-by-step explanation:
number of quarters ---------x
number of dimes ------------y
therefore, x + y = 37---------------times 10 both sides --------10x + 10y = 370-------equation 1
0.25x + 0.1y = 5.5 -----times 100 both sides -------25x + 10y = 550 ------equation 2
equation 2 minus equation 1 is 25x + 10y - 10x - 10y = 550 - 370 ------ 15x = 180 -------x = 12
there are 12 quarters
