Answer:
Neithere
Step-by-step explanation:
the answer is not 6,2 ive tried it ?
The solution of the given system of equation is (6, 2)
What is a system of equations?Two or more equations to be solved together, i.e., the solution must satisfy all the equations in the system.
Given are the equations, 3x + 2y = 22
-x + 4y = 2
Solving by elimination,
Multiplying the second equation by 3, we get
3x+2y = 22
-3x + 12y = 6
Adding the equation, we get
2y+12y = 22+6
24y = 28
y = 2
Putting y=2 we get
3x+2*2=22
3x+4 = 22
3x = 18
x = 6
Hence, The solution of the given system of equation is (6, 2)

Ok need to find missing measurements for number 5
And need number 9 answered I have uploaded the homework problems
Thanks so much!
Answer:
Step-by-step explanation:
5) ΔGHJ ≅ ΔXYZ
ΔGHJ is an isosceles triangle. So, GH = JH
GH =JH = 27 ft
a) GJ =XZ
GJ = 18 ft
b) XY = GH
XY = 27 ft
c) ZY = JH
ZY = 27 ft
d) ∠H = ∠Y
∠H = 38
In ΔGHJ,
∠G = ∠J {Isosceles triangle property}
Let ∠G = ∠J = x
∠G + ∠H + ∠J = 180 {angle sum property of triangle}
x + 38 + x = 180
38 +2x = 180
2x = 180 - 38
2x = 142
x = 142/2
x = 71
∠G = ∠J = 71
e) ∠Z = ∠J
∠Z = 71
f) ∠J = 71
9) ΔQRS ≅ ΔMNP
QR = 11 ; QS =15
MP = 2x +1
MP = QS
2x + 1 = 15
2x = 15 - 1
2x = 14
x = 14/2
x = 7
m∠S = 84
m∠R = 32
m∠Q = 17y - 4
In ΔQRS,
m∠Q + m∠R + m∠S = 180 {Angle sum property of triangle}
17y - 4 + 32 + 84 = 180
17y + 112 = 180
17y = 180 - 112
17y = 68
y = 68/17
y = 4

A bike shop offers three kinds of cycles-tricycles, bicycles, and unicycles. Together, the cycles in the shop have a total of
98 wheels and 46 seats. (Tricycles have 3 wheels, bicycles have 2 wheels, and unicycles have 1 wheel. All cycles have 1 seat.)
There are twice as many bicycles as tricycles. How many of each type of cycle are in the shop?
Answer:
Number of Uni Cycles = 7
Number of Bi Cycles = 26
Number of Uni Cycles = 39
Total Wheels = 98
Total Seats = 46
Step-by-step explanation:
Uni Cycles consist of 1 wheel
7 x 1 = 7 wheels
Bi Cycles consist of 2 wheels (twice than tri cycle)
26 x 2 = 52 wheels
Tri Cycles consist of 3 wheels
13 x 3 = 39 wheels
Total seats = 7 + 26 + 13 = 46
Total wheels = 7 + 52 + 39 = 98
The number of cycles is given below:-
Number of Uni Cycles = 7
Number of Bi Cycles = 26
Number of Uni Cycles = 39
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Total Wheels = 98
Total Seats = 46
Uni Cycles consist of 1 wheel
7 x 1 = 7 wheels
Bi Cycles consist of 2 wheels (twice as tricycle)
26 x 2 = 52 wheels
Tri Cycles consist of 3 wheels
13 x 3 = 39 wheels
Total seats = 7 + 26 + 13 = 46
Total wheels = 7 + 52 + 39 = 98

Ash cannot decide which of two washing machines to buy. The selling price of each is $360. The first is marked down by 30%. The second is marked down by 10% with an additional 20% off. Find the sale price of each washing machine. Use pencil and paper. Explain why ash should buy the first washing machine rather than the second if the machines are the same except for the selling price.
Answer:
The answer is the first one.
Step-by-step explanation:
Okay, so the first one is solved like this:
You do 360*30%. 30% is 0.3 in decimal form. So 360*0.3=108. 108 is the amount that is discounted, NOT the price. You have to do 360-108, which is 252. The discounted price is $252.
Now the second one is solved like this:
You do 360*10% FIRST because the problem says it was marked 10% BEFORE the 20%. 10%=0.1, so 360*0.1=36. You subtract 360-36, which is 324. Then, you multiply 324 by 20% or 0.2, to get 64.8, which is the discount of 20%. You subtract 324-64.8, which is $259.20. So the first one is the answer because it is cheaper since 252 is less than 259.20. If you need this explanation, don't use this word for word. Summarize this in YOUR own words!
He should by the first washing machine because it cost less than the second washing machine.
hannah's allotment is a rectangle and has an area of 188m². if the length of the allotment is 12m, what is its perimeter? give your answer in metres (m).
Answer:
P = 55.33 meters
Step-by-step explanation:
A=188(m^2)= L*W
L=12m
A/L=W
(188/12) meters=W=47/3
P=2W+2L
P=2(12m) + 2(47/3 m)
= 24 + 94/3 meters
P = 55.33 meters

Answer:
Reduced fraction
Step-by-step explanation:
One can always multiply numerator and denominator by the same number in order to find equivalent fractions. By in the case in which only multiplication (and not cancelling common factors) will help find an equivalent fraction, si when we are dealing with an already reduced fraction.
For example:
1/3 (one third), we can multiply numerator and denominator by a factor of 2 and get the equivalent fraction 2/6 as shown below:
[tex]\frac{1}{3} =\frac{1*2}{3*2} =\frac{2}{6}[/tex]
but one cannot reduced the fraction 1/3 any further because it is already a reduced fraction.

Find the rate of change
1foot 2inches (14inches) 8inches
1foot 2inches (14inches) 8inches
1foot 1inch (13inches) 7.5inches
1foot 5inches (17inches) 8inches
1foot 6inches (18inches) 8inches
The rate of change is D. 1foot 5inches (17inches) 8inches.
What is the foot?The foot is a measure of a unit of length (or distance) in US units, which equals 12 inches.
The rate of change is the difference between x and y variables. It can be mathematically expressed as Change in input/Change in output. The formula for the rate of change is as follows:
= Δx/Δy
where Δ = change
Calculations:14inches + 8inches = 22inches
13inches + 7.5inches = 20.5inches
18inches + 8inches = 26inches
But 17inches + 8inches = 25inches
Question Completion:Find the rate of change from 2feet 1 inch (25inches) to 8inches.
Thus, the rate of change is D. 1foot 5inches (17inches) 8inches.

The simplified form of the expression (5.23x + 3.76) − (3.67x − 6.39) is
Answer:
1.56x + 10.15
Step-by-step explanation:
(5.23x + 3.76) – (3.67x – 6.39)
(a + b) – (c – d) = a + b – c + d
Remove the parentheses and change the signs as needed:
5.23x + 3.76 – 3.67x + 6.39.
Group the like terms and simplify:
5.23x – 3.67x + 3.76 + 6.39
1.56x +10.15.
The simplified form of (5.23x + 3.76) – (3.67x – 6.39) is 1.56x + 10.15.

Step-by-step explanation:
-9x + 5 < 17 AND 13x + 25 < -1
13x + 25 < -1
Subtract 25 from both sides;
13x < -26
Divide both sides by 13;
x < -2
-9x + 5 < 17
Subtract 5 from both sides;
-9x < 12
Divide both sides by -9
