(do not solve, just answer how many solutions) *
1)0
2)1
3)2
4)Infinitely many
Answers
Answer: Your answer should be 1.
The given equation 2(x + 2) = 2 + 2x has zero solution. which is the correct answer would be an option (A).
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The equation is given in the question following:
2(x + 2) = 2 + 2x
We have to determine the number of solutions to the given equation.
As per the given question, we have
⇒ 2(x + 2) = 2 + 2x
Apply the distributive property of multiplication, and
⇒ 2x + 4 = 2 + 2x
Rearrange the terms of variable x in the above equation,
⇒ 2x - 2x = 2 - 4
⇒ 0 = -2
This is not true, so the given equation has no solution.
Thus, the equation 2(x + 2) = 2 + 2x has zero solution.

[tex]h=20[/tex]
Step-by-step explanation:
[tex]A = \frac{1}{2}h(B+b)[/tex]
[tex]150=\frac{1}{2}h( 8+7)[/tex] (substitution)
[tex]300=h(8+7)[/tex]
[tex]15h=300[/tex]
[tex]h=20[/tex]
Hope this helps :)
Answer:
h = 20
Step-by-step explanation:
A = 1/2h(B+b) , A = 150, B = 8, b = 7
lets rearrange the equation so we can solve for h
[tex]\frac{2A}{(B+b)} =h[/tex]
2(150) / (8+7) = h
300/15 = h
20 = h

Paul Smith pays $50.00 a month for group health insurance. There is a $300 deductible. His medical bills for the last year were $2,600.00. Paul’s insurance company provided payment of 80% of the bills less the deductible. What was the insurance company's payment?
Answers
Answer:
$1360
Step-by-step explanation:
Smith pays a monthly payment to the insurance company = $50
So in 12 months, he pays = 12 x 50
= $ 600
Now subtracting a $ 2600 by the deduction of amount $300 , i.e. $2300.
Now multiplying it by 20 percent as the insurance company pays the 80% leaving Smith with 20%, to get $460.
Now adding $460 with $300, as these amount Smith paid and he got $760.
Now monthly payment = $760 + $600
= $1360

A retail store makes k%
profit on the selling price. What is the least integer value of k
that will enable the store to make a profit of at least 30%
of the cost of the item?
Please answer as soon as possible. i do not understand. me and my friends dont uderstand.
Answers
Answer:
10
Step-by-step explanation:
The store wants to make a 20% profit:
Multiply the cost of the toy by 1.20 ( cost plus 20%).
6.25 x 1.20 = $7.50
This means when the toy is sold at 25% off, it needs to be $7.50 to make the 20% profit.
When the item is 25% off, that means it would sell for 75% of the original price.
Now to find what the price needs to be before the 25% off divide the profit price by 75%
7.50 / 0.75 = $10
K = $10

Which set of equivalent measures does not indicate that two triangles must be congruent?
A anglo-angle-angle B. side-angle-side
C. angle-side-angle D. angle-angle-side
Answers
Answer:
C. angle-side-angle
D. angle-angle-side
Step-by-step explanation:
A triangle is bounded by three sides, thus it has three angle. When two triangles are compared, the length of sides and angles could be similar or not. Thus, the triangle may be congruent or not congruent.
The relationship between congruent triangles can be expressed as regards to their sides, angles, or both.
From the given question, when the three angles of two given triangles are the same, then the two triangles are congruent. This relationship can be expressed as Angle-Angle-Angle.
Also, when two triangles have two equal sides and an included angle to be equal (i.e Side-Angle-Side), then they are congruent.

y > 1/2x + 2
Step-by-step explanation:
The points shown on the line are separated by a "rise" of 1 unit vertically, and a "run" of 2 units horizontally. Its slope is rise/run = 1/2.
The line crosses the y-axis at y=2, so the y-intercept is 2.
The boundary line is then ...
y = mx + b . . . . . . . where the slope is m and the y-intercept is b
y = 1/2x + 2 . . . . . . the equation of the boundary line
__
The line is dashed, and the shaded area is above the line, where y-values are greater than the y-value on the line. Then the y-values on the line are NOT included in the solution set. The inequality is ...
y > 1/2x + 2

75/w = 150/100 can be used to find the whole, w.
Use the language of percent to explain whether
w is less than or greater than 7
Answers
Answer:
w is greater than 7
Step-by-step explanation:
Given
[tex]\frac{75}{w} = \frac{150}{100}[/tex]
Required
Determine if w is less than or greater than 7
[tex]\frac{75}{w} = \frac{150}{100}[/tex]
Cross Multiply
[tex]w * 150 = 75 * 100[/tex]
[tex]150w = 7500[/tex]
Solve for w
[tex]w = \frac{7500}{150}[/tex]
[tex]w = 50[/tex]
Convert to percentage
[tex]w = 50 * 100\%[/tex]
[tex]w = 5000\%[/tex]
w is greater than 7 because 50 or 5000% is greater than 7
