Answer:
x=4
Step-by-step explanation:
2x+3x+1=21
(2x+3x)+(1)=21
5x+1=21
5x+1=21
Step 2: Subtract 1 from both sides.
5x+1−1=21−1
5x=20
Step 3: Divide both sides by 5.
Answer:
x=4
Step-by-step explanation:
2x+3x+1=21
Simplify both sides of the equation.
2x+3x+1=21
(2x+3x)+(1)=21(Combine Like Terms)
5x+1=21
5x+1=21
Subtract 1 from both sides.
5x+1−1=21−1
5x=20
Divide both sides by 5.
5x /5 = 20 /5

The population of a city is 51,000 and is decreasing at a rate of 1.75% per year. Use an exponential function to find the expected population in 5 years. Round to the nearest whole number.
Answer:
46,691
Step-by-step explanation:
Given that:
Initial population, P = 51000
Decreasing rate = 1.75% = 0.0175
Time, t = 5 years
Using the relation :
A (t) = Po * ( 1 - r)^t
A(t) population after t years
Po = Initial population figure
r = rate of decrease
A(t) = 51000 * (1 - 0.0175)^5
A(t) = 51000 * (0.9825)^5
A(t) = 51000 * 0.91550937355400390625
A(t) = 46690.9780
Hence, population after 5 years will be : 46,691

Step-by-step explanation:
Kerr is going to pack 9 baby carrots, 12 crackers and 18 grapes into lunch boxes . How many of each food item will there be in a lunch box if she packs the items into the greatest number of indentical lunch boxes
Answer:
3 baby carrots, 4 crackers and 6 grapes
Step-by-step explanation:
Given
[tex]Baby\ Carrots = 9[/tex]
[tex]Crackers = 12[/tex]
[tex]Grapes = 18[/tex]
Required
Determine the number of each food item in a lunch box
First we need to get the number of lunch boxes by calculating the GCF of 9, 12 and 18
[tex]9 = 3 * 3[/tex]
[tex]12 = 2 * 2 * 3[/tex]
[tex]18 = 2 * 3 * 3[/tex]
The GCF is:
[tex]GCF = 3[/tex]
This implies that the number of lunch boxes is 3.
If there are 3 lunch boxes:
3 baby carrots will go into each lunch box because 3 * 3 = 9 4 crackers will go into each lunch box because 4 * 3 = 126 grapes will go into each lunch box because 6 * 3 = 18What does the question mark stand for in the following when you factorise:
4d3 + 6de =? (2d2 +3e
Answer:
Question mark stands for 2d
Step-by-step explanation:
Here, we want to get what the question marks stands for
As we can see, the left was factorized to give the right
So, we have that ;
4d^3 + 6de = 2d(2d^2 + 3e)
so the question mark stands for 2d

Here is a rectangle ABCD.
20 cm
30 cm
The length of the rectangle is increased by 20%.
The width of the rectangle is increased by 10%.
Find the percentage increase in the area of the rectangle.
Answer:
25% increase
Step-by-step explanation:
length is 24 inches after the increase and width is 33 inches (i did length as up and down and width as side to side, that's how I always do it but I might be wrong let me know and I can fix it)
the area before it gets increased it 600
after the increase its 792
and 600 is 75.75% of 792
so it would be 25.25% increase

Which expression represents the height of the pyramid? StartFraction 3 V Over y squared EndFraction units (3 V minus y squared) units (V minus 3 y squared) units StartFraction V Over 3 y squared EndFraction units
Answer:
Height = 3v/y² units
StartFraction 3 V Over y squared EndFraction units
Step-by-step explanation:
The volume of a solid right pyramid with a square base is v units3 and the length of the base edge is y units. which expression represents the height of the pyramid? units (3v – y2) units (v – 3y2) units units
Volume of a solid right pyramid = 1/3 × area of the base × height
Volume of a solid right pyramid = v units³
Area of the base = y² unit²
Volume of a solid right pyramid = 1/3 × area of the base × height
v = 1/3 × y² × height
Height = v ÷ 1/3 × y²
= v × 3/1y²
= (v × 3) / y²
= 3v / y²
Height = 3v/y² units
StartFraction 3 V Over y squared EndFraction units

A side of the triangle below has been extended to form an exterior angle of 66°. Find
the value of x.
xo
48°
66°
Step-by-step explanation:
By Exterior Angle Theorem, the sum of the 2 inner angles in the triangle will be equal to the exterior angle.
=> x + 48° = 66°, x = 18°.
The required measure of the angle x is given as 18°.
Given that,
A side of the triangle below has been extended to form an exterior angle of 66°
Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.
Here,
The property of the triangle state that the sum of the remote interior angle is equal to the measure of the remote exterior angle,
So,
x + 48 = 66
x = 18°
Thus, The required measure of the angle x is given as 18°.
