DIG DEEPER! Solve the
2x – y + 3z = -1
x + 2y - 4z = -1
y -- 2z = 0
The solution is
Answer:
x = - 1, y = 2, z = 1
Step-by-step explanation:
Given the 3 equations
2x - y + 3z = - 1 → (1)
x + 2y - 4z = - 1 → (2)
y - 2z = 0 → (3)
Add (1) and (3) term by term
2x + z = - 1 → (4)
Multiply (1) by 2
4x - 2y + 6z = - 2 → (5)
Add (2) and (5) term by term
5x + 2z = - 3 → (6)
Multiply (4) by - 2
- 4x - 2z = 2 → (7)
Add (6) and (7) term by term
x = - 1
Substitute x = - 1 into (4)
- 2 + z = - 1 ( add 2 to both sides )
z = 1
Substitute x = - 1, z = 1 into (2)
- 1 + 2y - 4 = - 1
- 5 + 2y = - 1 ( add 5 to both sides )
2y = 4 ( divide both sides by 2 )
y = 2
solution is (x, y, z ) = (- 1, 2, 1 )

How much can the Owen family expect to pay, per year, to raise the child from birth to 18 years of age?
A)$11,378
B)$12,846
C)$13,188
D)$13,458
The Owen family expect to pay, per year, to raise the child from birth to 18 years of age is $18203.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that,
Cost of raising a child in 2 years
Birth to 5 years old $65,250
5 to 18 years old $139,560
4 y Public college $24,382
4 y private college $98,470
Here, total money = 65,250+139,560+24,382+98,470
= $327662
Money to raise in a year = 327662/18
= $18203
Therefore, the Owen family expect to pay, per year, to raise the child from birth to 18 years of age is $18203.

Step-by-step explanation:
Is 18x-2y = 26 linear or non linear?
Answer: it’s a linear function
Step-by-step explanation:
18x-2y=26 as -2y= -18x + 26 by adding 18x to both sides, and then y=9x - 13 by dividing both sides by -2. So, it represents a linear function
Answer:
It's linear
Step-by-step explanation:
18x-2y=26
Because it has two variables x and y

One acute angle of a right triangle measures 35°. What is the measure of the other acute angle? ·
Answer:
55
Step-by-step explanation:
A right triangle always has one angle which is equal to 90 degrees. You have been given the second angle which is 35 degrees hence to get the second acute angle you do:
180 - (90+35)
= 55
Answer:
we have,,
the traingle having one actue angle is 35degree
i.e angle ACB be 35degree, AND
another one angle ABCis 90degree
Also, let angle Bac be x
now,,
x+35+90=180(being the sum of traingle)
or,x=180-125
or,x=55
therefore, the value i.e angle BAC be 55 degree.
7. The Majestic company increased the cost of an Astros jersey from $80 to $110. By what percentage was the price of
the Astros jersey increased?
Answer:
50%
Step-by-step explanation:
The cost = $80
Increased cost = $120
% Increase = (120-80) / 80 * 100
% Increase = 40/80 * 100
% Increase = 0.5 * 100
% Increase = 50%
So, the price of the Astros jersey increased by 50%

On a busy day, a shop sells a total of 15 desks and chairs for a total amount of $960.The desks sell for $120 each and the chairs sell for $50 each.
(a) Express the information as two equations. Let d equal the number of desks and let c equal the number of chairs.
(b) Solve the equations simultaneously to find how many of each were sold.
Answer:
- sold 15 desks + chairs
- each desk is $120
- each chair is $50
- total amount is $960
- desk = d
- chairs = c
(a) i/ d + c = 15
ii/ 120d + 50c = 960
(b) d+c = 15 --------- (1)
120d + 50c = 960 --------(2)
from (1) d+c = 15
c = 15-d --------- (3)
substitute (3) into (2)
120d + 50c = 960
120d + 50(15-d) = 960
120d + 750 - 50d = 960
120d - 50d = 960 - 750
70d = 210
d = 210/70
d = 3
substitute d=3 into (3)
c = 15-d
c = 15-3
c = 12
thus, 3 desks and 12 chairs were sold

Answer:
part to part is comparing one part of a group to another part of the group but part to whole is comparing one part of the group to the enire group

Step-by-step explanation:
0.5 (n-4) -3 = 3 - (2n+3)
Answer:
n = 2
Step-by-step explanation:
0.5n - 2 - 3 = 3 - 2n -3
0.5n + 2n = 2 + 3 + 3 -3
2.5n = 5
n = 2
Answer:
Step-by-step explanation:
0.5n - 2 - 3 = 3 - 2n - 3
Solving like terms
0.5n - 5 = - 2n
-5 = - 2n - 0.5n
-5 = - 2.5n
-5/-2.5 = n
2 = n

Joe borrowed $6,000 from the bank at a rate of 7% simple interest per year. How much interest did he pay in 8 years?
Answer:
$3360
Step-by-step explanation:
7% of $6000=$420
$420 time 8= $3360
Hope this helped! :)
Answer:
$3,360
Step-by-step explanation:
So first of all you want to start by finding what P, r and t would be.
P = Principal amount ($$)
r = interest rate (%)
t = time (years)
Once I found all of those I put them into the equation (l = Prt) and solved (by putting it into a calculator obviously). That is how I came up with my answer. Check the screenshot provided to see what P, r and t would be and to see all my work! :)
Hope this helps! :)

The train station clock runs too fast and gains 8 minutes every 10 days.
How many minutes and seconds will it have gained at the end of 4 days?
Answer: 3 minutes and 12 seconds
Step-by-step explanation: You can see 8 minutes every 10 days as a fraction (8/10). This can be simplified to 4/5, meaning that the amount of time gained will be 4/5 of the # of days that have passed. 4/5 of 4 days is 3.2 minutes, and that can be converted to 3 1/5. 60 seconds divided by 5 is 12 seconds, meaning that 1/5 of a minute is 12 seconds. Therefore, the answer is 3 minutes and 12 seconds.

PLEASE HELP JESUS I DONT UNDERSTAND
Answer:
22 units
Step-by-step explanation:
The formula for the area of a trapezoid is A = [tex]\frac{a+b}{2} h[/tex] where a and b are the bases and h is the height of the trapezoid.
In this case, the numbers that will be replacing a and b will be 4 and 7, making the equation look like this: A = [tex]\frac{4+7}{2}h[/tex] .
Now, you have to determine the height of the trapezoid, which in this case is 4 units. The equation will now look like this: A = [tex]\frac{4+7}{2}4[/tex].
You can solve from here like so:
A = [tex]\frac{11}{2}4[/tex]
A = 5.5(4)
A = 22
