Step-by-step explanation:
4x + 16 = 2x + 34
4x - 2x = 34 - 16
2x/2 = 18/2
x = 9
2(9) + 34
= 18 + 34
= 52
52 x 2
= 104
360 - 104
= 256
256/2
= 128
Therefore angle 1 is 128°

Ms. Barcht Open a savings account with $50 and deposit $25 every week. Mrs. Greene save $75 every week. How many weeks will Mrs. Greene have more money in her account than ms. Bracht?
A. 25x+75>50
B. 75x=25x+50
C. 75x>25x+50
D. 75x<25x+50
Answers
Answer:
C
Step-by-step explanation:
Ms. Barcht's savings account can be modeled with the expression
50 + 25x
Mrs. Greene's savings account can be modeled with the expression
75x
Since the question is how many weeks Mrs. Greene will have more money than Ms. Bracht. we use an inequality to contain the all the solutions.
Mrs.Greene > Ms. Bracht
75x > 25x + 50
Answer:
The answer would be C. 75x>25x+50
Step-by-step explanation:
The answer would be C. because Ms. Barcht started with $50 and deposits $25 every week while Mrs. Greene saves $75 a week. 7 days is a week so lets multiply $25 x 2 (2 weeks). Ms. Barcht would have $100 by the end of 2 weeks and Mrs. Greene would have $150 by the end of 2 weeks because $75x2 is $150

Answer:
0.1125
Step-by-step explanation:
1.35 divided by 12 = 0.1125
Answer:
$0.11 per egg
Step-by-step explanation:
unit cost means how much each one costs
there are 12 eggs in a dozen
so all you have to do is divide $1.35 by 12
which equals $0.1125
but money is only counted by the hundredths place so we have to round
and that would be $0.11

for any positive integer n, the sum of the first n positive integers equals n(n 1)/2. what is the sum of all the even integers between 99 and 301 ?
Answers
The sum of all the even integers between 99 and 301 is 20200
To find the sum of even integers between 99 and 301, we will use the arithmetic progressions(AP). The even numbers can be considered as an AP with common difference 2.
In this case, the first even integer will be 100 and the last even integer will be 300.
nth term of the AP = first term + (n-1) x common difference
⇒ 300 = 100 + (n-1) x 2
Therefore, n = (200 + 2 )/2 = 101
That is, there are 101 even integers between 99 and 301.
Sum of the 'n' terms in an AP = n/2 ( first term + last term)
= 101/2 (300+100)
= 20200
Thus sum of all the even integers between 99 and 301 = 20200

Answers
Answer:

Step-by-step explanation:
here,given equation of a line id
4x-y-2=0.. eqn(i)
equation of any line parallel to line (i) is
4x-y+k=0...eqn(ii)
since, the line(ii) passes through (1,5)[replacing x=1 and y=5 in eqn(ii), we get]
4*1-5+k=0

Sasha deposits $400 at River Point bank.
She will have $50 more in First oak bank (without interest).
Amount in First Oak Bank is $87.84 than at River Point after 2 years.
What is Simple Interest and Compound Interest?Simple interest is the interest obtained over the principal amount on a certain rate.
Compound interest is the amount of interest which is calculated on the principal amount as well as the amount accumulated over the previous period.
First oak bank is simple with 6% interest.
Final amount in simple interest, A = P(1 + rt), where P is the principal amount , r is the interest rate and t is the number of years.
A = 450 (1 + (0.06 × 2)) = $504
River point bank is 2% compounded annually
Final amount in compound interest, A = P(1 + r/n)^(nt), where, P is the principal amount, r is the interest rate, t is the number of years and n is the number of times interest compounded annually.
P = 850 - 450 = 400
n = 1, since compounding is only 1 time in a year
A = 400(1 + 0.02)² = $416.16
Amount which is more in First oak is $504 - $416.16 = $87.84
Hence the amount more in the First oak account is $87.84.

Janice puts a fence around her rectangular garden. The garden has a length that is 9 feet less than 3 times the width. Which system of equations represents is the dimensions of the rectangular garden if the perimeter is 63?
Answers
Step-by-step explanation:
Let the width of the garden be b and its length is 9 feet less than 3 times the width.
Length = 3b-9 ...(1)
The perimeter of the garden = 63
We need to find the system of equations that represents is the dimensions of the rectangular garden.
Perimeter = 2(l+b)
63 = 2(3b-9+b) [from equation (1)]
31.5 = (3b-9+b)
31.5 = (4b-9)
31.5+9 = 4b.....(2)
b = 10.12
Hence, the equations are showsn in equation (1) and (2).

This is the answer because if James pays for 1 shirt from company C he would be paying $60, but if he were to pay for 1 shirt at company D he would be paying $35. So that's why its >. Anyway, the s goes on the second number because that's the price for every shirt, And the first number is by itself because its a one-time printing fee.

area of square increasing at 112 centimeters squared per second, rate of change when side is 7 centimeters
Answers
The area rate of change of side of square is 8 cm/s;
dA/dt = 112 cm²/s;
Area = (r)²; where r is the side of square;
dA/dt = (dA/dr)(dr/dt);
dA/dr = 2r and dA/dt = 112 cm²/s;
Therefore; dr/dt = 112/2r at r = 7;
dr/dt = 112/14 = 8 cm/s;
Rate of change of side of square is 8 cm/s;

Answer: The measure of angle 3 is 50 degrees.
Step-by-step explanation:
We know that angle 2 is 130 degrees.
Angle 1 and angle 2 are verticle angles which means that they are across and equal to each other.
So angle 1 and angle 2 are 130 degrees.
Add up both angle 1 and angle 2, 130 + 130 = 260.
Now, all of these angles add up to be 360 degrees in total as they make a circle and there are 360 degrees in one.
Subtract 260 from 360, 360 - 260 = 100.
Since both angle 3 and angle 4 are also verticle angles we need to split the 100 degrees evenly, 100 ÷ 2 = 50.
So, angle 3 is 50 degrees.

Identify the range of the function y=-3x+6 when the domain is {-1,2,4}
A. {-6,0,9}
B. {-9}
C. {3,-12,-18}
D. {-3,12}
E. {-6,9}
Answers
When the domain is {-1,2,4} , the range of the function y =-3x+6 is {-6,0,9}
Given,
The function y= -3x+6
The domain of the function is the complete set of all possible input for the function.
The domain = {-1,2,4}
The range of the function is the complete set of all possible output for the function.
Substitute the values in the function
f(-1)= -3×-1+6
=3+6
= 9
f(2)= -3×2+6
=-6+6
= 0
f(4)= -3×4+6
=-12+6
=-6
So, -6,0 and 9 the possible output of the function y= -3x+6
The range of the function y= -3x+6 is {-6,0,9}
Hence, When the domain is {-1,2,4} , the range of the function y =-3x+6 is {-6,0,9}
