[tex]38 + 7x - 21 = 9x + 9[/tex]
Combine like terms.
[tex]17 + 7x = 9x + 9[/tex]
Eliminate a x.
[tex]17 = 2x + 9[/tex]
[tex]8 = 2x[/tex]
[tex]x = 4[/tex]
38 + 7x - 21 = 9x + 9
7x + 17 = 9x + 9
Subtract both sides 9
7x + 17 - 9 = 9x + 9 - 9
7x + 8 = 9x
Subtract sides 7x
7x - 7x + 8 = 9x - 7x
8 = 2x
Divide both sides by 2
8 ÷ 2 = 2x ÷ 2
x = 4
All the students in the sixth grade either purchased
their lunch or brought their lunch from home on
Monday.
35% of the students purchased their lunch
182 students brought their lunch from home
How many students are in the sixth grade?
Step-by-step explanation:
Well 182 students is 65% so it's 182 add 30%
but in all honesty I don't know what that 30% is, sorry, but it's better to write that instead of nothing, it still gets you more marks
sixth graders scare me, they're so small

The value of y varies directly with x. When y=75, x= 0.5. What is the value of y when x is 2.25?
Even though I pulled up the work, I still don’t know what to do ♀️
Answer:
y=337.5 when x = 2 1/4
Step-by-step explanation:
Well first we want to know what's the function here
How do we get y to be 75 if x is .5?
75/.5 is 150
so can we say the function is 150x=y
Now lets plug
2 1/4 or 2.25 for x
2.25*150 = 337.5
y=337.5 when x = 2 1/4
Hope that helps!

Find the area of each circle. Use 3.14 for a. Round to the nearest tenth
Diameter = 16 m
Students, draw anywhere on this slide!
Answer:
201
Step-by-step explanation:
Diameter (d) of a circle = 16 m.
Radius (r) of a circle = 16/2 = 8 m.
Now, we know,
[tex] \dag [/tex] Formula of Area of a circle is πr².
So, Area of a circle = 3.14 × (8)²
Area of a circle = 3.14 × 8 × 8
Area of a circle = 200.96 = 201 sq. m.
The area of a circle is 201 sq. m. [Answer]Sebastian is at a restaurant with his family and is choosing an appetizer, a main course,

He sum of seven interior angle measurements in an octagon equal 845º. What is the angle measurement of the 8th angle?
Answer: [tex]235^{\circ}[/tex]
Step-by-step explanation:
Given
The Sum of the seven interior angles of an octagon is [tex]845^{\circ}[/tex]
for a Polygon, the sum of the interior angles is given by [tex](n-2)180^{\circ}[/tex]
for octagon, n=8
The Sum of interior angles is [tex](8-2)360^{\circ}=1080^{\circ}[/tex]

Tapanga drew triangle XYZ on her paper the measure of angle X was 80 degrees angle y was congruent to angle Z what was measure of angle Z
Answer:
50degrees
Step-by-step explanation:
The sum of angle in the triangle XYZ is 180degrees, hence;
<X + <Y + <Z = 180
Given
m<X = 80degree
m<Y = m<Z
Required
m<Z
Substitute the given angle
80 + m<Z + m<Z = 180
80 + 2m<Z = 180
2m<Z = 180 - 80
2m<Z = 100
m<Z = 100/2
m<Z = 50degrees
Hence the measure of angle Z is 50degrees

The ratio of mango ice cream to strawberry ice-cream is 1:4. Total no. of ice cream is 30. What is the no. of mango ice-cream?
Step-by-step explanation:
let the ratio of ice cream be x&4x
total number of ice cream =30
now,
x+4x=30
5x=30
x=30/5
x=6
mango ice cream=x=6
strawberry ice cream=4x=4×6=24
hope it helps.
Answer:
6 !
Step-by-step explanation:
mango = x
strwberry = 4x
total = x+4x = 5x = 30
5x= 30
x= 30/5 = 6
mango = x= 6
strwberry = 4x = 24

Three pairs of shoes cost $108. If each pair costs the same, how much does each one cost?
A.$32
B.$34
C.$36
D.$38
Answer:
C: 36
Step-by-step explanation:
There are 3 pairs of shoes. They all cost the same. Since these shoes add up to 108 dollars, they basically multiply by three to get to 108. (3x=108) If you want to figure out the cost of one shoe you just have to reverse the process by using division. So just do simple division by dividing 108 by three (108/3=x) and there is your answer, 36.

What is the total number of unique triangles with side lengths of 6.5 centimeters, 6 centimeters, and 2.5 centimeters?\
Answer:
Total 9 unique triangles can be formed
Step-by-step explanation:
For triangles to be unique, length of one side can be arranged in 3 different ways
Let us L1, L2 and L3 are the three sides
Now, length of 6.5 cm can be at maximum three positions i.e L1, L2 and L3
Like wise length of 6.0 cm can be at maximum three positions i.e L1, L2 and L3
and length of 2.5 cm can be at maximum three positions i.e L1, L2 and L3
Hence, total ways of making unique triangles are
3 + 3+ 3= 9
You use 7 1/2 c flour to make 3 loaves of bread. The second person uses the same recipe. He will make b loves of bread using f cups of flour. Write an equations that represents of the relationship between b and f.
Answer:
b = 2/5f
Step-by-step explanation:
Cups of flour = loaves of bread
7 1/2 c = 3
c = 3 ÷ 7 1/2
c = 3 ÷ 15/2
= 3 × 2/15
= 6/15
= 2/5
c = 2/5
Cups of flour = loaves of bread
2/5 f = b
b = 2/5f

Answer:
∠x = 36°
Step-by-step explanation:
∠a = 180° - 106° = 74°
=> ∠b = 180° - 40° - 74° = 66°
=> ∠c = 180° - 66° = 114°
=> ∠d = 180° - 114° - 30° = 36°
=> ∠x = ∠d = 36°

Step-by-step explanation:
A circular carnival ride has a diameter of 120 ft. Suppose you board a gondola at
the bottom of the circular ride, which is 6 ft above the ground, and rotate 240°
counterclockwise before the ride temporarily stops. How many feet above ground
are you when the ride stops?
Answer:
The height above ground when the ride stops is 96 feet
Step-by-step explanation:
The given diameter of the carnival ride, d = 120 ft.
The height of the ride above the ground, h = 6 ft.
The angle through which the ride is rotated, θ = 240° counterclockwise
Therefore, we have;
The radius of the ride, r = d/2
∴ r = 120 ft./2 = 60 ft.
We note that at 180° rotation, the ride is at the highest point, [tex]h_{max}[/tex] = 6 ft. + 120 ft. = 126 ft.
When the ride rotates a further 240° - 180° = 60° the height drops from the maximum point by y = 60 ft. × cos (60°) = 30 ft., such that the final height above ground is therefore;
h = 126 ft. - 30 ft. = 96 ft.
The height above ground when the ride stops, h = 96 ft.

I need help finding the area and perimeter you will get plz
Answer:
I couldn't find the area, but the perimeter is 200.
Step-by-step explanation:
To get the answer of 200 perimeter, all you have to do is add up all the sides of the shape.
10+10+25+25+25+15+15+75 = 200.
After adding up the numbers, you are left with a perimeter of 200.
Respuesta:
No pude encontrar el área, pero el perímetro es 200.
Explicación paso a paso:
Para obtener la respuesta de 200 de perímetro, todo lo que tienes que hacer es sumar todos los lados de la forma.
10 + 10 + 25 + 25 + 25 + 15 + 15 + 75 = 200.
Después de sumar los números, te queda un perímetro de 200.
