Question:
Here are five sums. Use the distributive property to write each sum as a product with two factors.
[tex](a)\ 2a + 7a[/tex] [tex](b)\ 5z - 10[/tex] [tex](c)\ c - c^2[/tex] [tex](d)\ r + r+ r+ r[/tex] [tex](e)\ 2x - \frac{1}{2}[/tex]
Answer:
[tex](a)\ 2a + 7a = 9a[/tex]
[tex](b)\ 5z - 10 = 5(z - 2)[/tex]
[tex](c)\ c - c^2 = c(1 - c)[/tex]
[tex](d)\ r + r + r + r = 4r[/tex]
[tex](e)\ 2x - \frac{1}{2} = \frac{1}{2}(4x - 1)[/tex]
Step-by-step explanation:
Required
Apply distributive property
[tex](a)\ 2a + 7a[/tex]
Apply distributive property [Factor out a]
[tex]2a + 7a = a(2 + 7)[/tex]
[tex]2a + 7a = a(9)[/tex]
Open bracket
[tex]2a + 7a = a*9[/tex]
[tex]2a + 7a = 9a[/tex]
[tex](b)\ 5z - 10[/tex]
Express 10 as 5 * 2
[tex]5z - 10 = 5z - 5*2[/tex]
Apply distributive property [Factor out 5]
[tex]5z - 10 = 5(z - 2)[/tex]
[tex](c)\ c - c^2[/tex]
Express c as c * c
[tex]c - c^2 = c - c * c[/tex]
Apply distributive property [Factor out c]
[tex]c - c^2 = c(1 - c)[/tex]
[tex](d)\ r + r+ r+ r[/tex]
Express r as r * 1
[tex]r + r + r + r = r * 1 + r * 1 + r * 1 + r *1[/tex]
Apply distributive property [Factor out 1]
[tex]r + r + r + r = r(1+1+1+1)[/tex]
[tex]r + r + r + r = r * 4[/tex]
[tex]r + r + r + r = 4r[/tex]
[tex](e)\ 2x - \frac{1}{2}[/tex]
Express 2x as 4x/2
[tex]2x - \frac{1}{2} = \frac{4x}{2} - \frac{1}{2}[/tex]
Apply distributive property [Factor out 1/2]
[tex]2x - \frac{1}{2} = \frac{1}{2}(4x - 1)[/tex]

Question 1 of 5 A home has an original value of $249,000. Each year, the value of the home decreases by 7.1%. Select the equation that models the situation after t years. V = 249,000(1.071)t V = 249,000(0.929)t V = 249,000(0.071)t V = 249,000(0.29)t
Answer:
V = 249,000(0.929)^t
Step-by-step explanation:
100% - 7.1% = 92.9% = 0.929
0.929 must be raised to t, the number of years.
V = 249,000(0.929)^t

Sam picked 48 oranges in 5 minutes. How many oranges could she pick in 2 minutes?
Step-by-step explanation:
48 oranges in 5 minutes means she picked 48 oranges in 300 seconds.
Divide 48 by 300 to get what she would pick in one second.
This equals 0.16
Multiply 0.16 by 120 seconds [how many seconds are in two minutes].
This equals 19.2 oranges in two minutes. As she cannot pick 0.2 of an orange, she could pick 19.

how to solve 5x+20=5
Answer:
x= -3
Step-by-step explanation:
if u want explain let me know
Answer:
x = -3
Step-by-step explanation:
5x + 20 = 5
Subtract 20 from both sides
5x + 20 - 20 = 5 -20
{If two numbers have different sign, subtract and the result will have the sign of the bigger number. 20 -5 = 15, bigger number is 20, so -15}
5x = - 15
Divide both sides by 5
5x/5 = -15/5
x = - 3

how do i find the x and y intercepts of x+y-5=0
Answer:
To find x intercept. Substitute y=0 in the given equation, and solve for x . x−0=5. x=5. Therefore, x intercept =(5,0)
To find y intercept. Substitute x=0 in the given equation, and solve for y . 0−y=5. y=−5. Therefore, y intercept =(0,−5)
Step-by-step explanation:
Answer:
y intercept = -5

Triangle QRS is rotated 180° about the origin. On a coordinate plane, triangle Q R S has points (negative 4, 1), (negative 4, 4), (2, 1). What are the coordinates of point S'? (2, 1) (1, –2) (–1, –2) (2, –1)
Answer:
(-2,-1)
Step-by-step explanation:
Given
[tex]Q =(-4,1)[/tex]
[tex]R = (-4,4)[/tex]
[tex]S = (2,1)[/tex]
180 degrees rotation

Determine the coordinate point S'
For a 180-degree rotation, the transformation rule is: (x, y) to (-x, -y)
So:
[tex]S = (2,1)[/tex] ==> [tex]S' = (-2,-1)[/tex]
Hence, the coordinate point of S' is (-2,-1)

An artist is using right triangles in her design. If all the triangles have an angle measure of 24, what is the measure of the third angle?
Answer:
66°
Step-by-step explanation:
Given that :
Right angle measure of a triangle are used in a design :
A right angles triangle has one of its angle equals 90 ;a
Since the second angle is given as 24 ; b
The measure of the third angle ; c will be :
Sum of angles in a triangle = 180
(a + b + c) = 180
(90 + 24 + c) = 180
c = 180 - 114
c = 66°
what is x? plz help :)
Answer:
13
Step-by-step explanation:
using the Pythagorean theorem a²+b²=c²
or the two shorter sides square added together equal the longest side squared
5²+12²
5²=25
12²=144
144+25=169
then we just have to take the square root of 169
√169=12

I'm honestly sorry that I'm asking so many questions.
Solve for X in the Diagram.
Answer:
[tex]\Huge\boxed{x=8}[/tex]
Step-by-step explanation:
Hello There!
Remember the sum of all of the angles in a triangle is 180
so we can use this equation to solve for x
180 = 50 + 60 + 8x + 6
now we solve for x
step 1 combine like terms
50 + 60 + 6 = 116
now we have
180=8x+116
step 2 subtract 116 from each side
116 - 116 cancels out
180 - 116 = 64
now we have
8x = 64
step 3 divide each side by 8
8x/8=x
64/8=8
we're left with x = 8

given right triangle abc and sin A= 1/2, cos A = √3/2
Answer:
true
Step-by-step explanation:
sinA² + cosA²=1
⇔(1/2)² + cosA²=1
⇔cosA=±(√3/2)
Yes, the triangle is a right triangle.
What is a right triangle?A triangle is called a right triangle if it has an angle measuring 90°.
Given that in a triangle if Sin A = 1/2 and Cos A = √3/2, then the triangle is a right triangle,
So,
Sin A = 1/2
Sin A = Sin 60°
A = 60°
Also, we know that the sine and cosine of an angle is complementary,
So,
Sin A = Cos (90-A)
Therefore, Cos(90-30)° = Cos 30° = √3/2
Therefore, ABC is a right triangle.
Hence the triangle is a right triangle.

This system of linear inequalities can be used to find the possible heights, in inches, of Darius, d, and his brother William, w.
d ≥ 36
w < 68
d ≤ 4 + 2w
Which statements must be true about their heights? Select three options.
Darius is at least 36 inches tall.
Darius is at most 36 inches tall.
William’s height is less than 68 inches.
William’s height is at least 68 inches.
Darius is less than 4 inches taller than twice William’s height.
Darius is no more than 4 inches taller than twice William’s height.
(A) Darius is at least 36 inches tall.
(C) William’s height is less than 68 inches.
(F) Darius is no more than 4 inches taller than twice William’s height.
Step-by-step explanation:
edge2022
The inequality w < 68 can be written as William’s height is less than 68 inches.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Given that, d ≥ 36, w < 68 and d ≤ 4 + 2w.
Atleast means all probabilities larger than the given probability ('at least') Atmost means all probabilities smaller than the given probability ('at most')
Here, d ≥ 36
Darius is at least 36 inches tall.
w < 68
William’s height is less than 68 inches.
d ≤ 4 + 2w
Darius is no more than 4 inches taller than twice William’s height.
Therefore, the inequality w < 68 can be written as William’s height is less than 68 inches.
