x=12
Step-by-step explanation:
Let's solve your equation step-by-step.
1/2x+1/3 x=10
Hey there!☺
[tex]Answer:\boxed{x=12}[/tex]
[tex]Explanation:[/tex]
[tex]\frac{1}{2}x+\frac{1}{3}x=10[/tex]
1/2x + 1/3x = 10 Simplify both sides
(1/2x + 1/3x) = 10 Combine like terms
5/6 x = 10
(6/5) * (5/6x) = (6/5) * (10) Multiply both sides by 6/5.
x = 12
Hope this helps!

Answer:
16.6
Step-by-step explanation:
By the property of intersecting secants outside of a circle, we have:
[tex]5 \times (5 + x) = 6 \times (6 + 12) \\ 25 + 5x = 6 \times 18 \\ 25 + 5x = 108 \\ 5x = 108 - 25 \\ 5x = 83 \\ x = \frac{83}{5} \\ x = 16.6[/tex]
Using compatible numbers, which is the best estimate of (28.5)(7.1)
Answer:
203
Step-by-step explanation:
estimate 28.5 = 29
estimate 7.1 = 7
there for 29 x 7 = 203
I had the same question!!!The required estimated value of the given expression is 202.
What is an estimate of the numbers?The estimate is defined as a rough view calculation that helps to predict where the product value lies.
Here,
Given expression,
= (28.5)(7.1)
Multiplying the number under the parenthesis,
Gives,
= 202.35
Now, rounding the numbers, Since the number after the decimal place is close to zero,
= 202.
Thus, the required estimated value of the given expression is 202.

Properties of Special Triangles:
Calculate the size of angle AEF
Answer:
90 degrees
Step-by-step explanation:
Answer:
The angle of AEF is 90°.
Step-by-step explanation:
Given that DEF is an equilateral triangle so all angles are the same which is 60° and in a regular square, all angles are 90°. Next, we have to find ∠ADE :
∠EDF = 60° / ∠CDF = 180° / ∠CDA = 90°
∠ADE = 180° - ∠EDF∠CDA
∠ADE = 180° - 60° - 90°
∠ADE = 30°
Given that ADE is an isosceles triangle so ∠ADE and ∠AED have the same angles. Lastly, we have to find ∠AEF by adding ∠AED and ∠DEF together :
∠AED = 30° / ∠DEF = 60°
∠AEF = ∠AED + ∠DEF
∠AEF = 30° + 60°
∠AEF = 90°

someone please help,
5=5ax+1 please help, its due in an hour.
solve for x
Answer:
x= 4/5a
Step-by-step explanation:
5=5/ax+1
Step 1: Multiply both sides by a.
5a=a+5x
Step 2: Flip the equation.
a+5x=5a
Step 3: Add -a to both sides.
a+5x+−a=5a+−a
5x=4a
Step 4: Divide both sides by 5.
5x/5=4a/5
x= 4/5a

Apply the distributive property to create an equivalent expression 1/5(15+10k)
Answer:
3 + 2k
Step-by-step explanation:
1/5(15+10k)
distribute
1/5 * 15 + 1/5 * 10k
3 + 2k
Answer:
3 + 2k
Step-by-step explanation:
First, I am going to explain what the distributive property is. Lets say he had the expression a(b + c). We can "distribute" the a to the b and c:
a(b + c) = ab + ac
We can apply the distributive property to the expression 1/5(15 + 10k):
1/5(15 + 10k)
= (1/5)(15) + (1/5)(10k)
= 3 + 2k
By using the distributive property, we found the expression 3 + 2k.

The multiplication of (2.4)(–1.8) and (0.6)(–0.4) gives negative values option third is correct.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
As we know, by the arithmetic operation rule
Multiplication of two negative values is positive.
Multiplication of one negative and one positive value is negative.
Multiplication of two positive values is positive.
In option third:
(2.4)(-1.8) = -4.32
(0.6)(-0.4) = -0.24
Thus, the multiplication of (2.4)(–1.8) and (0.6)(–0.4) gives negative values option third is correct.

Determine if the statement below makes sense. Explain.
Four friends administered a bake sale table for a day. They made a total of $376.35 over the course of the day. Determined to give everyone an equal share of the money, each friend received $94.0875.
A. This statement makes sense. Dividing 376.35 by 4 results in 94.0875.
B. This statement does not make sense. Money values must be rounded to the nearest dollar. Each friend should receive $94.
C. This statement does not make sense. Money values must be rounded to the nearest cent. Each friend should receive $94.08.
D. This statement does not make sense. Dividing 376.35 by 4 results in 91.8375. Each friend should receive $91.8375 instead.
Answer:
c
Step-by-step explanation:
$376.35 / 4 does equal to $94.0875 but when it comes to money, it should be rounded to the nearest cent being $94 and .08 cents.

On a 210-mile trip, Cameron drove at an average speed of 60 miles per hour for the first x hours. He then
completed the trip, driving at an average speed of 50 miles per hour for the remaining y hours. If x = 1,
what is the value of y?
y =
Answer:
[tex]y = 3[/tex]
Step-by-step explanation:
Given
Trip = 250 miles
Speed for first x hours = 60 miles/hour
Speed for next y hours = 50 miles/hour
x = 1
Required
Find y
To solve this question, we'll make use of:
[tex]Distance = Speed * Time[/tex]
For x hours:
[tex]Distance = 60miles/hour * x[/tex]
Substitute 1 hour for x
[tex]Distance = 60\ miles/hour * 1\hour[/tex]
[tex]Distance = 60\ mile[/tex]
For y hours:
[tex]Distance = 50\ miles/hour * y\ hours[/tex]
[tex]Distance = 50y\ miles[/tex]
Given that total distance is 210 miles;
We have that:
[tex]Total Distance = 60\ miles + 50y\ miles[/tex]
[tex]210\ miles = 60\ miles + 50y\ miles[/tex]
Solve for y
[tex]210 - 60 = 50y[/tex]
[tex]150 = 50y[/tex]
[tex]y = \frac{150}{50}[/tex]
[tex]y = 3[/tex]
Hence,
y = 3 hours
