solve for the value of w
Answer:
w = 13
Step-by-step explanation:
Right angle: 90°
Write an equation:
(4w + 5)° + 33° = 90°
Solve for w.
(4w + 5)° = 90° - 33°
(4w + 5)° = 57°
You can take away the brackets.
4w + 5 = 57
Isolate w.
4w = 57 - 5
4w = 52
w = 52 ÷ 4
w = 13

Solve for the value of the variable: 7x+ 10 = 4x + 16
Enter the answer
Step-by-step explanation:
7x + 10 = 4x + 16
3x + 10 = 16 (subtract 4x on both sides)
3x = 6 (subtract 10 on both sides)
x = 2 (divide 3 on both sides)
Somebody please help me with this !!!
Step-by-step explanation:
Case 1 :
[tex]3x + 2y = 6 \\ 4x + y = 2 \\ 3x = 6 - 2y \\ x = \frac{6 - 2y}{3} = \\ x = 2 - \frac{2y}{3} \\ 4(2 - \frac{2y}{3} ) + y = 2 \\ 8 - \frac{8y}{3} + y = 2 \\ - 1.67y = - 6 \\ [/tex]
[tex]y = 3.59 \\ x = 2 - \frac{2y}{3} \\x = 2 - \frac{2 \times 3.59}{3} \\ \\ x = - 0.39[/tex]
Case 2 :
[tex]3x + 2y = 6 \\ 4x - y = 2 \\ x = 2 - \frac{2y}{3} \\ 4(2 - \frac{2y}{3} ) - y = 2 \\ 8 - \frac{8y}{3} - y = 2 \\ - 3.67y= - 6 \\ y = 1.63[/tex]
[tex]x = 2 - \frac{2y}{3} \\ x = 2 - \frac{2 \times 1.63}{3} \\ x = 2 - 1.087 \\ x = 0.913[/tex]
Consider the diagram below of an equilatera triangle.
Answer:
4 = n.
13 ft.
Step-by-step explanation:
An equilateral triangle means that all of the sides are equal.
This means: 2n + 5 = 3n + 1 = 5n -7
You can pick two of those sides to set up an equation to solve for n.
For example, 2n + 5 = 3n + 1.
Then you will need to isolate the variable.
Subtract 1 from each side to get 2n + 4 = 3n.
Subtract 2n from each side to get 4 = n.
Substitue 4 for n into one of the equations.
2n + 5
2(4) + 5
8 + 5 = 13
Each side is 13 ft.

120 cubic ft is the volume of rectangular prism having a length of 10ft, a height of 3ft, and a width of 4ft
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
A rectangular prism is a 3D figure with 6 rectangular faces.
Given, rectangular prism has a length of 10ft, a height of 3ft, and a width of 4ft.
To find the volume of rectangular prism we have to multiply length, width and height.
Volume =Length×Width×Height
Put the values of length, width and height in the above formula.
=10×4×3
=120 cubic ft
Hence 120 cubic ft is the volume of rectangular prism having a length of 10ft, a height of 3ft, and a width of 4ft

2y-3x=-27
5y+3x=6
Answer:
The answer to the first one is y=3/2x-27/2
The answer to the second one is y=-3/5x+6/5
Step-by-step explanation:
1. 2y-3x=-27
first, you want to add '3x' to both sides.
2y=3x-27
then you want to divide '2' from both sides. you do not want to use the 'y' because you want to keep the 'y' on its own side.
y=3/2x-27/2
2. 5y+3x=6
First, you want to subtract '3x' from both sides.
5y=-3x+6
Now, you want to divide '5' from both sides.
y=-3/5x+6/5

For two days, your boss decides to double the amount you make if on day 1, you make $70 dollars and on day 2, you make$80 dollars, write an expression for the total commission you earn?
Answer:
300
Step-by-step explanation:
Day 1: $70
Day 2: $80
Total commission = day 1 × 2 + day 2 × 2
= 70 × 2 + 80×2
= 140 + 160
= 300
Or
Total commission = 2(day 1 + days 2)
= 2(70 + 80)
= 2(150)
x = 300

5. Use the angle addition formula to find the expression for cos (a+b).
Answer:
Step-by-step explanation:
Trigonometric identities are used to show the equality of expressions involving trigonometric functions. These trigonometric functions are the sine, the cosine, and the tangent as well as their respective reciprocals which are cosecant, the secant, and the cotangent,
Some trigonometric identities are:
tanθ = sinθ / cosθ; secθ = 1 / cosθ; cosecθ = 1 / sinθ; cotθ = 1 / tanθ = cosθ / sinθ
The angle addition formula for cos is given as:
cos(α + β) = cosαcosβ - sinαsinβ
Therefore:
cos(a + b) = cosacosb - sinasinb

What equation describes the circle that is centered at (8, 3) and has a radius of 9
Answer:
(x-8)²+(y-3)² = 81Step-by-step explanation:
The general equation of a circle is expressed as;
(x-a)²+(y-b)² = r² where;
(a, b) is the centre of the circle
r is the radius
Given the centre (8, 3) and the radius of 9, the equation of the circle will be;
(x-a)²+(y-b)² = r²
(x-8)²+(y-3)² = 9²
(x-8)²+(y-3)² = 81
hence the required equation is (x-8)²+(y-3)² = 81

Step-by-step explanation:
If you roll a number cube two times, what is the probability of rolling an even on the first roll and a four on the second roll?
Answer:
1/12
Step-by-step explanation:
Probability is a ratio derived as the number of possible outcomes divided by the total outcome.
On a number cube, the even sides are 2, 4 and 6. This means that the possible outcome for rolling an even is 3 while the total outcome is 6. Hence the probability of rolling an even P(E)
= 3/6
The probability of rolling a 4 P(4)
= 1/6 (4 appears on one side)
Hence the probability of rolling an even on the first roll and a four on the second roll
P(En4) = 3/6 * 1/6
= 3/36
= 1/12
