Answer:
95
Step-by-step explanation:
Let x be the number of children
10x+35 = money
15x+5 = money
Set the equations equal
10x+35 = 15x+5
Subtract 10x from each side
35 = 5x+5
Subtract 5 from each side
30 =5x
Divide by 5
30/5 =5x/5
6 =x
There are 6 children
10x+35 = money
10(6) +35
60+35
95
The amount of money is 95
4(x + 2) = 2x + 10
explain each step plz
Answer:
[tex]x=1[/tex]
Step-by-step explanation:
[tex]4(x + 2) = 2x + 10[/tex]
Distribute 4(x+2).
[tex]4x+8 = 2x + 10[/tex]
Subtract 2x and 8 from both sides.
[tex]4x-2x=10-8[/tex]
[tex]2x=2[/tex]
Divide both sides of the equation by 2.
[tex]\frac{2x}{2} =\frac{2}{2}[/tex]
[tex]x=1[/tex]
Answer:
x = 1
Step-by-step explanation:
4(x + 2) = 2x + 10
You start by expanding 4(x +2)
i.e. 4x + 8 = 2x + 10
Then, subtract 2x from both sides of the equation
4x + 8 - 2x = 2x + 10 - 2x
4x - 2x + 8 = 2x - 2x + 10
2x + 8 = 10
Subtract 8 from both sides of the equation
i.e. 2x +8 - 8 = 10 - 8
2x = 2
Divide both sides of the equation by the coefficient of x above(which is 2)
[tex]\frac{2x}{2} = \frac{2}{2}[/tex]
x = 1

What is the area of a rectangle with length (3^2)^2 meters and width of 3^2 meters?
Answer:
729m^2
Step-by-step explanation:
Area of rectangle = length x width
From the question, we know that length = 3^2^2 = 81 ( three squared is 9. Nine squared is 81)
width = 3^2 = 9.
Now for the area: length x width = 81 x 9 = 729m^2.

Answer:
alternate exterior angles
Step-by-step explanation:
The two horizontal lines are simply two lines.
The other line is a transversal since it intersect the two lines at two different points.
Angles 1 and 8 are on two different sides of the transversal. That makes them alternate angles. They are on the outside of the two lines. That makes them exterior angles. Put the two things together and they are:

What is angle m 2 ? What is angle m 1?
Answer:
Angle measure two is equal to 75º and Angle measure one is equal to 105º
Step-by-step explanation:
I know this because angle one is alternate exterior angle with angle 7 and angle seven forms a staight line with angle 75 so to find angle 7 you have to do 180-75 and that would equal 105.
for angle two it is interior angles with angle 75 so this means that are congruent angles which means they both have the same measure
Answer: <2 is 75 degrees & <1 is 105 degrees
Step-by-step explanation:
multiply the polynomials (4x^2+3x+7(8x-5)
A. 32x^3-44^2-71x-35
B. 32x^3-4x^2-41x+35
C. 32x^3+4x^2+41x-35
D. 32x^3+4x^2+41x+35
Answer:
32x^3 + 4x^2 + 41x - 35
Step-by-step explanation:
Multiply each of the terms in bracket 1 with those in bracket 2.
4x^2 x 8x = 32x^3
4x^2 x -5 = -20x^2
3x x 8x = 24x^2
3x x -5 = - 15x
7 x 8x = 56x
7 x -5 = -35
Now, put them together and simplify:
32x^3 - 20x^2 + 24x^2 - 15x + 56x - 35
After simplifying:
32x^3 + 4x^2 + 41x - 35

Answer:
x = 7.5
Step-by-step explanation:
Given BE is parallel to CD and intersects the other 2 sides, it divides those sides proportionally, that is
[tex]\frac{AE}{ED}[/tex] = [tex]\frac{AB}{BC}[/tex] , substitute values
[tex]\frac{10}{8}[/tex] = [tex]\frac{x}{6}[/tex] ( cross- multiply )

x = 7.5
Dana has to pay 25% tax on any income above £24,000 per year. Dana is paid £36,000 annually. Calculate the amount of money she receives after tax each month.
Answer:
£2,750
Step-by-step explanation:
Tax rule: 25% tax on any income above £24,000 per year
It means that upto £24,000 there is no tax and the amount above £24,000
is taxable.
Annual payment of Dana = £36,000
Hence, she will be taxed only on amount above £24,000 out of £36,000.
Lets find amount above £24,000 = £36,000- £24,000 = £12,000
Tax on £12,000 = 25% of £12,000 = 25/100 * £12,000 = £3,000
Thus, £3,000 will be deducted as tax annually out of total earning of £36,000.
Amount paid to Dana after deduction of tax annually = £36,000 - £3,000
Amount paid to Dana after deduction of tax annually is £33,000
As one year has 12 months , hence it can be also said that in 12 months she is paid £33,000
the amount of money she receives after tax in 12 month = £33,000
Dividing LHS and RHS by 12
The amount of money she receives after tax in 12/12 month = £33,000/12
The amount of money she receives after tax in 1 month = £2,750
The amount of money Dana receives after tax each month is £2,750.

Step-by-step explanation:
Which of the following is most likely the next step in the series?
A.
B.
C.
D.
Answer:
B
Step-by-step explanation:
each time the step changes, the amount of vertices(points) increases by 1. the last number of points was 4, so if you increase 4 by 1 you will get 5. figure B has 5 points!
Answer:
Option B
Step-by-step explanation:
With the circle series, there is a figure with an increasing number of points that are on the circle.
Circle one has two dots, circle two has three dots, circle three has four dots, etc.
It would make the most sense if the circle in the next series have five dots.
Option B should be the correct answer.
The point (2,9) lies on a circle and the center of the circle is at the point (2,1). What is the equation of this circle? A. (x - 2)2 - (y - 1)2 = 64 B. (x - 2)2 + (y - 1)2 = 64 C. (x + 2)2 + (y + 1)2 = 64 D. (x - 1)2 - (y - 2)2 = 8
Answer:
B:(x-2)^2+(y-1)^2=64
Step-by-step explanation:
center is (2,1), point is (2,9)
so the radius=9-1=8
(x-2)^2+(y-1)^2=64

Answer:t=8
Step-by-step explanation:
solve for t by simplifying both sides of the equation,then isolating the variable
Answer:
[tex]t = 8[/tex]
Step-by-step explanation:
→You need to get "t," by itself, and to do this, you must multiply both sides by the reciprocal of [tex]\frac{1}{4}[/tex], which is 4. You are multiplying because you can't divide by a fraction.
[tex]\frac{1}{4} t=2[/tex]
[tex]4*\frac{1}{4} t=2*4[/tex]
[tex]t = 8[/tex]
complete the square to solve the equation below (check all that apply)
Answer:
A and D
Step-by-step explanation:
We have to create a perfect square. To make x^2+bx+c into a perfect square, c has to be (b/2)^2. In this case, b is -10. so, c has to be (-10/2)^2, which is 25. To make the left hand side 25, we would have to add 30 to both sides.
This leads to a new equation:
x^2 - 10x + 25 = 9+30
x^2 - 10x + 25 = 39
Now, we can change the left hand side to a perfect square.
(x-5)^2 = 39. (the -5 is b/2)
Then we square root both sides;
x-5 = +/- sqrt39. (When you square root an expression, remember that you need to include both the positive AND negative)
x = 5-sqrt39 or 5+sqrt39

Mike is flying a kite with a string that is 20 ft long is flying at a height of 16 ft.
What is the horizontal distance from Mike to the kite?
The horizontal distance from Mike to the kite will be 12 feet.
What is Pythagoras theorem?
The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.
Given that;
Mike is flying a kite with a string that is 20 ft long is flying at a height of 16 ft.
Now,
Since, Mike is flying a kite with a string that is 20 ft long is flying at a height of 16 ft.
Let the horizontal distance from Mike to the kite = x feet
Hence, We can formulate;
⇒ 20² = x² + 16²
⇒ 400 = x² + 256
⇒ x² = 400 - 256
⇒ x² = 144
⇒ x = 12 feet
Thus, The horizontal distance from Mike to the kite will be 12 feet.

HELP I will give brainliest to make the perfect shade of orange cake frosting, Mya needs 8 drops of yellow food coloring for every 12 drops of red food coloring. If she adds 32 drops of yellow food coloring to her frosting, how many drops of red food coloring should she add
Answer: 48 red drops
Step-by-step explanation:
ratio of yellow food drops to red food drops is 8:12
8:12 simplifies to 2:3
2:3 = 2/5:3/5
2x/5 = 32 = # of yellow drops (where x is the total # of drops)
2x/5 = 32
2x = 160
x = 80
Since there are 80 total drops and 32 yellow drops, there must be 48 red drops (80-32=48)
