6 - 2/3 (x+5) = 4x solve algebraically for the exact value of x
Answer:
x = 2
Step-by-step explanation:
1 - Rewrite
6 - 2/3 (x+5) = 4x
2 - Distribute
6 - 2/3x + 10/3 = 4x
3 - Combine like terms and get x alone
6 10/3 - 2/3x = 4x
+2/3x +2/3x
6 10/3 = 4 2/3x
------------------------------- Convert to decimals
6.3333333333.... = 4.333...x
-------------------------------- Divide both sides by 4.33...x
2 = x
Hope this helps :)

What is the point-slope form of an equation for a line that passes through the point (5, –5) with the slope of 2?
Answer:
y-5=2(x+5)
Step-by-step explanation:
Anna makes unique jewelry. The owner of the "Unique" store agreed with Anna to deliver 20 bracelets a week. At the moment, Anna has 80 bracelets made, and can make 17 bracelets a week. For how many consecutive weeks will Anna be able to supply her bracelets to the "Unique" store?
Answer:
7 weeks
Step-by-step explanation:
80 ÷ 20 = 4
She over those four week she makes 17 per week. So,
17 × 4 = 68
Next, divide the product by 20:
68 ÷ 20 = 3.4
But 3.4 is only 3 full weeks so then its 3.
Lastly, add the 3 weeks we just solved for the the 4 weeks from before and you get 7 weeks.
So, Anna will be able to supply the "Unique" store for 7 weeks.
I HOPE I HELPED!!!!!!!!!! :))))))

WHAT IS FRICTION BETWEEN????? NEED ANSWERS ASAP
Answer:
Friction is a force between two surfaces that are sliding, or trying to slide, across each other.
Step-by-step explanation:
For example, when you try to push a book along the floor, friction makes this difficult.
Answer:
Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Fluid friction occurs in liquids and gases.

Review the diagram.
On a coordinate plane, a vector labeled 120 meters forms angle 25 degrees with the x-axis. It goes to point mirror 1. Another vector labeled 90 meters goes from point mirror 1 to mirror 2. It forms angle 20 degrees with a horizontal line. Point mirror 2 goes to (0, 0).
A laser beam is aimed 25° from horizontal at a mirror 120 m away. The beam bounces off the mirror and continues for an additional 90 m at 20° above horizontal until it hits a target, mirror 2. What is the distance between the origination point and the target?
approximately 85 m
approximately 122 m
approximately 174 m
approximately 194 m
Answer:
Approximately 85 m
Step-by-step explanation:
Let x represent the distance between the origination point and the target
Distance between original point and mirror 1 = 120 m
Distance between mirror 1 and mirror 2 = 90 m
The measure of angle Opposite the distance between the origination point and the target = 20 + 25 = 45°
Use Cosine rule to find x as shown below:
Use The Law of Cosines to find side a first:
[tex] a^2 = b^2 + c^2 - 2bc \times Cos(A) [/tex]
Where,
a = x
b = 90 m
c = 120 m
A = 45°
Plug in the values
[tex] x^2 = 90^2 + 120^2 - 2(90)(120) \times Cos(45) [/tex]
[tex] x^2 = 22,500 - 21,600 \times Cos(45) [/tex]
[tex] x^2 = 22,500 - 15,273.5065 [/tex]
[tex] x^2 = 7,226.4935 [/tex]
Square both sides
[tex] x = \sqrt{7,226.4935} [/tex]
[tex] x = \sqrt{7,226.4935} [/tex]
x ≈ 85 m

What are the coordinates of the vertex of the graph of the absolute value function h(x) = 3|x + 5| + 2?
Answer:
(-5,2)
Step-by-step explanation:
h(x) = 3|x + 5| + 2 is an absolute value function in vertex form. Vertex form is f(x) = a | x - h | + k with a vertex at (h,k). So find h and k in the function, 3|x + 5| + 2, but remember in the formula h is negative so flip the sign of what ever is in your function. So if h=-5 and k=2, then the vertex is (-5,2).
Melanie rides her bike. The circumference of her bike tire is 2.8 m, and the tire revolves 1.5 times per second. What is the distance Melanie rides in 100 seconds?
Answer:
420 m
Step-by-step explanation:
The distance travelled in 1 second:
2.8 m * 1.5 revolves
= 2.8 * 1.5
= 4.2 m
Distance travelled in 100 seconds:
4.2 m * 100
= 420 m

Ethan ran 11 miles in 2 hours. What is the unit rate of miles to hour?
Answer:
5.5 mph
Step-by-step explanation:
Answer:
5.5 miles per hour
Step-by-step explanation:
This is a fraction equal to
11 miles ÷ 2 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 2
11 miles ÷ 2
2 hours ÷ 2
=
5.5 miles
1 hour
=
5.5 miles
hour
= 5.5 miles per hour

A microwave oven costs $124.85 before it is marked down. If it is marked down by 63%, what is its new price, to the
nearest cent?
A.$78.66
b. $61.85
C. $58.68
d. $46.19
Answer:
D ($46.19)
Step-by-step explanation:
$124.85 * (100% - 63%)
= $124.85 * 37 %
= $124.85 * 0.37
= 46.1945
= $46.19 (to the nearest cent)
