Solve for c.
2(c +1) = 10
Answer:
c = 4
Step-by-step explanation:
[tex]2(c+1) = 10[/tex]
Lets divide both the sides by 2.
[tex]=> \frac{2 (c+1)}{2} = \frac{10}{2}[/tex]
[tex]=> c + 1 = 5[/tex]
Now , lets substract 1 on both the sides.
[tex]=> c + 1 - 1 = 5 - 1[/tex]
[tex]=> c = 4[/tex]
The solution to the equation 2(c + 1) = 10 is c = 4.
We have,
To solve for c in equation 2(c + 1) = 10, we will apply the distributive property and simplify the equation step by step.
Let's solve it:
Distribute the 2 to the terms inside the parentheses:
2c + 2 = 10
Move the constant term (2) to the right side by subtracting 2 from both sides of the equation:
2c + 2 - 2 = 10 - 2
Simplifying further:
2c = 8
Divide both sides of the equation by 2 to solve for c:
(2c) / 2 = 8 / 2
Simplifying further:
c = 4
Therefore,
The solution to the equation 2(c + 1) = 10 is c = 4.

tax. What is your final cost for the jeans?
$128.40
O
$120
$111.60
280
Answer:
$128.40
Step-by-step explanation:
200 × 0.4 = 80
200 - 80 = 120
120 × 0.07 = 8.4
120 + 8.4 = 128.4
Answer:
$128.40
Step-by-step explanation:
1. Find the cost after the discount.
Multiply the original cost by the discount percentage. This is the amount that was taken off of the original price.
$200 x 40% = $80
Subtract the discount from the original price.
$200 - $80 = $120.
2. Calculate the tax.
Tax is 7% of the final cost. Multiply the final cost by the tax rate. This determines how much tax was added.
$120 x 7% = $8.40
Add the tax amount to the discounted price.
$120 + $8.40 = $128.40
The final cost is $128.40.

which pair of triangles can be proven congruent by the HL theorem?
Answer:
the middle one because HL is hypotenuse-leg and the middle one is the one that has a congruent hypotenuse and a congruent leg
(HL theorem only works with a right triangle)
Step-by-step explanation:
The pair of triangles that can be proven congruent by the HL theorem is the triangles in the middle.
Calculations and ParametersAccording to the HL Theorem:
A triangle would contain:
A hypotenuse-legCongruent hypotenuseCongruent leg.Therefore, we can see that the pair of triangles in the middle of the diagram are congruent through the HL theorem as they satisfy the conditions.

Select all true statements.
A) Dilation's of an angle must be congruent to the original angle.
B) Dilation's if a triangle must be congruent to the original triangle.
C) Dilation's of a segment must be congruent to the original segment.
D) Dilation's of a circle must be congruent to the original circle.
Answer:
A) Dilation's of an angle must be congruent to the original angle.
B) Dilation's if a triangle must be congruent to the original triangle.
Step-by-step explanation:
Dilation is one of rigid transformations in which the size of an angle or object is either increased or decreased, to produce an image, with respect to a given factor. In this process, the dimensions of the object are affected but its orientation remains the same.
When a figure is dilated, the new figure is congruent to the original figure. Also, when an angle undergoes dilation, its measure is not affected. Thus, it would be congruent to the original angle.
The length of a rectangle is three less than four times the width. The perimeter of the rectangle is 54 feet. Find the width of the rectangle.
Answer:
6 ft
Step-by-step explanation:
Let the width = w
Then the length = 4w - 3
perimeter = 2(length + width)
perimeter = 2(4w - 3 + w)
perimeter = 2(5w - 3)
perimeter = 10w - 6 = 54
10w - 6 = 54
10w = 60
w = 6
Answer: The width is 6 ft

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
3x - 5y = 13
x + 4y = 10
Step 2: Rewrite Systems
x + 4y = 10
Subtract 4y on both sides: x = 10 - 4yStep 3: Redefine Systems
3x - 5y = 13
x = 10 - 4y
Step 4: Solve for y
Substitution
Substitute in x: 3(10 - 4y) - 5y = 13Distribute 3: 30 - 12y - 5y = 13Combine like terms: 30 - 17y = 13Isolate y terms: -17y = -17Isolate y: y = 1Step 5: Solve for x
Define equation: x + 4y = 10Substitute in y: x + 4(1) = 10Multiply: x + 4 = 10Isolate x: x = 6Answer:
(6,1) x=6 and y=1
Step-by-step explanation:
EASY we can use Elimination or Substitution process
We are going to solve by
Elimination process
Subtract each other
(3x-5y=13)
(x+4y=10)
3x-5y=13;x+4y=10
To solve this multiply (x-4y=10) by 3 to get rid of the x
3x-12y=30
now u can subtract both
3x-12y=30 minus
3x-5y=13
17y=17
Divide both sides by 17
y=1
Now we have y lets plug it in to find x
x+4(1)=10
x+4=10
subtract 4 from both sides
x=6
x=6 and y=1
4(x - 5) + 36

Miya flips a coin and rolls a 6-sided number cube labled 1-6 and records tge outcome. About how many times is she likely to flip heads and roll a 3 out of 48 trials
Answer:
4 times
Step-by-step explanation:
Sample space :
6 sided cube = (1, 2, 3, 4, 5, 6)
Coin = (H, T)
Probability = required outcome / Total possible outcomes
Probability of head (H) = P(H) = 1 /2 = 0.5
Probability of 3 = P(3) = 1 /6 = 0.166666
Probability of heads and 3 on a single try = p(H) * p(3) = 0.5 * 0.166666 = 0.083333
Hence, expected number of times this is likely to occur in 48 tries :
0.083333 * 48 = 4

Two trains have to travel a distance of 300 miles. Train A goes at the speed of 50 mph and Train B goes at the speed of 60 mph. However, Train B leaves 1 hour later than Train A. When will the 2 trains meet?
Answer:
Both trains would meet in 6 hours time.
Step-by-step explanation:
Train A = 50 miles per hour
Train B = 60 miles per hour
Train B leaves 1 hour later than Train A: This means Train A started the journey first.
When will the 2 trains meet?
Both trains would meet when they both cover equal distance.
Distance = Speed * Time
First Hour
Train A = 50 miles
Train B = 0 miles
Second Hour
Train A = 100 miles
Train B = 60 miles
Third Hour
Train A = 150 miles
Train B = 120 miles
Fourth Hour
Train A = 200 miles
Train B = 180 miles
Fifth Hour
Train A = 250 miles
Train B = 240 miles
Sixth Hour
Train A = 300 miles
Train B = 300 miles
Both trains would meet in 6 hours time.

Determine the value of z for the system of equations. x + y + z = 2 3x - 2y + 2z = -8 8z - 12y - x = 12
Answer:
4Step-by-step explanation:
To get the value of z, we need to reduce the system of equation into two and 2 unknowns;
Add 1 and 3:
y - 12y + z + 8z = 2+12
-11y + 9z = 14 ....... 4
Also Multiply equation 1 by 3 and subtract from 2
Eqn 1 * 2 will give 3x + 3y + 3z = 6
Subtract from eqn 2;
3y-(-2y)+3z-2z = 6-(-8)
5y+z = 14 ....5
Solve 4 and 5
-11y + 9z = 14 * 5
5y+z = 14 * 11
________________
-55y + 45z = 70
55y + 11z = 154
Add both
45z+11z = 70+154
56z = 224
z= 224/56
z = 4
Hence the value of z is 4

Use the remainder theorem to determine if x = 2 is a zero of the following polynomial, and find the quotient and the remainder.
p(x) = x3 + 24x2 + 108x - 320
Answer:
(A) Yes, x = 2 is a zero of the polynomial.
The quotient is x² + 26x + 160 and the remainder is 0
Step-by-step explanation:
Given;
p(x) = x³ + 24x² + 108x - 320
Using remainder theorem to test if x = 2 is a zero of the given function
p(2) = (2)³ + 24(2)² + 108(2) - 320
= 8 + 96 + 216 - 320
= 0
Thus, x = 2 is zero of the function
(ii) to get the quotient and the remainder of the given function, divide the function by 'x - 2'
x² + 26x + 160
x - 2 √ x³ + 24x² + 108x - 320
- (x³ - 2x²)
0 + 26x² + 108x - 320
- (26x² - 52x)
0 + 160x - 320
- (160x - 320)
0 + 0
The quotient is x² + 26x + 160
The remainder is 0
Thus, the correct option is A.
Yes, x = 2 is a zero of the polynomial.
The quotient is x² + 26x + 160 and the remainder is 0
