Answer: (2, 19)
Step-by-step explanation:
There are three general ways to solve a system of equations:
- Substitution
- Elimination
- Augmented Matric
Since both given equations all have y isolated, substituting the value of y will be the most appropriate way here.
--------------------------------------------------------------------------------------------------------
Given
y=7x+5
y=x+17
Substitute y into the equations
7x+5=x+17
Subtract 17 on both sides
7x+5-17=x+17-17
7x-12=x
Subtract 7x on both sides
7x-12-7x=x-7x
-12=-6x
Divide -6 on both sides
-12/-6=-6x/-6
x=2
Substitute value into one of the equations
y=x+17
y=2+17
y=19

What is ¨0.83% of n is 18.26¨ (just tell me the value of n)
Answer:
N = 2,200'Percent (%)' means 'out of one hundred':
0.83% = 0.83 'out of one hundred',
p% is read p 'percent',
0.83% = 0.83/100 = 0.83 ÷ 100
Calculate percentage:
'Percentage' is obtained by multiplying 2,200 by 0.83%
0.83% × 2,200 =
(0.83 ÷ 100) × 2,200 =
(0.83 × 2,200) ÷ 100 =
1,826 ÷ 100 =
18.26

Find the missing side
13 ft
5 ft
x
Answer:
Assuming you're referring to the sides of a right triangle, the missing side X would be 12.
Step-by-step explanation:
The Pythagorean Theorem states that the two legs of a right triangle squared and added together is equal to the hypotenuse squared. [tex]13^{2}[/tex] is 169, [tex]5^{2}[/tex] is 25, 169 - 25 = 144. Take the square root of 144 and you'll get 12, which is the missing side of the right triangle.

Savannah is 9 years older thanDevante. The sum of their ages is 53. How old are Savannah and Devante?
(A) First write an equation you can use to answer this question. Use x as your variable.
The equation is _______
Answer: Devante is _______
and Savannah is ______
Answer:
Devante is 23 and Savannah is 32.
Step-by-step explanation:
We can set up a system of equations.
s - savannah's age
d - devante's age
s = d + 9
s + d = 53
Now we can substitute (d + 9) for s in the second equation.
(d + 9) + d = 53
2d + 9 = 53
2d = 46
d = 23
To find Savannah's age, we just add 9 to Devante's age. (plugging in 23 for d)
23 + 9 = 32
s = 32

URGENT!! PLEASE HELP!! What method could be used to prove the below triangles similar?
Answer:
Step-by-step explanation:
Please please please help.
Answer and Step-by-step explanation:
A. Cruz is correct.
B. When we have a negative within a cube root, what we can do is move the negative sign from inside to outside the cube root.
[tex]\sqrt[3]{-64} = -\sqrt[3]{64}[/tex]
Now that we have a positive number within the cube root, we can solve the cube root itself.
So what is the cube root of 64?
The answer is 4, and since we have a negative sign outside of the cuberoot, we just put a negative sign, our answer is -4.
C. Aaron could've got it wrong because he did it a square root instead of a cuberoot of 64. Square root of 64 is 8, while cube root is 4.
Jacob could've gotten it wrong because he must've followed the fallacy that you cannot cube root a negative number.
The difference of 8 and six times a number is a minimum of sixty-eight
Answer:
Let's represent the unknown number with the variable, x.
The word "difference" indicates subtraction and "times" indicates multiplication.
The "difference of 8 and six times a number" would be represented as: 8 - 6x
NOTE: The order of the terms is important (8- 6x is not the same as 6x - 8).
This expression 8 - 6x must be at least 68 to meet the requirement of being at least a "minimum".
The final inequality will be: 8 - 6x ≥ 68
Step-by-step explanation:

Number of Quarters:
Answer:
dimes:$8 quarters:$15
Step-by-step explanation:
im still in 6th grade
Answer:
55 dimes and 70 quarters
Step-by-step explanation:
Using a simple strategy of guess and check we know that the quarters will always be 15 more than dimes. From this we know it has to be around the 50s as 40s would bring us numbers too low and 60s too high. 55 happens to be answer for dimes as that brings in $5.50. 23-5.5=17.5 multiply that by 4 as each quarter is only valued at $0.25 you get the answer 70 which just so happens to meet the requirements of being 15 more than 55.

A contractor must haul a large amount of dirt to a work site. She collected information from two hauling companies. EX Excavation gives its prices in a table. Happy Hauling Service gives its prices in a graph.
Answer:
$24.5
Step-by-step explanation:
Its $24.5 for the rate of change for EZ Excavation
The EX Excavation will charge $980 for 40 cubic yards of dirt.
What is unit rate?A unit rate means a rate for one of something.
Given a graph showing cost for per cubic yard of dirt.
The unit rate = 196/8 = 490/20 = 637/26 = 24.5
Therefore, for 40 cubic yards of dirt = 40*24.5 = 980
Hence, The EX Excavation will charge $980 for 40 cubic yards of dirt.

40000 people visited the Emirates Park Zoo in Abu Dhabi last Year. Ratio of number of visitors of children to women to men is 4: 7: 9. Find the number of children, women and men who visited the zoo.
Answer:
40000 total visitors
Step-by-step explanation:
Let p represent a multiplier. Then the total number of visitors to the park is
4p + 7p + 9p = 40000.
This simplifies to 20p = 40000, so that p = 2000.
Then the number of children who visited is 4p = 8000; the number of women is 7p = 14000, and the number of men is 9p = 18000.
Summing up these results gives us the total number of chidren, women and men who visited the zoo last year: 8000 + 14000 + 18000, or 40000.

Answer:
6, 7, 2, 3
Step-by-step explanation:
supplementary means that two or more angles add together to equal 180 degrees
a straight line equals 180 degrees so the intersecting of a line creates two angles that are supplementary. That means <5 is supplementary with 6 and 7.
<5=<1 because the lines intersecting it are parrell. Using the same thinking process for angle 1 as above, it is supplementary with 2 and 3. and since 1 is equal to 5 it is also supplementary to 2 and 3.
