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
what is the solution (x,y) to the system of equations? x=10 3x+5y=20
Answer:
(10, -2)
Step-by-step explanation:
x = 10 (its given in the problem)
then plug in 10 for x in the second equation and solve for y
3(10) + 5y = 20
30 + 5y = 20
5y = -10
y = -2
so the solution is (10, -2)
Which value is equivalent to 7 multiplied by 3 multiplied by 2 whole over 7 multiplied by 5, the whole raised to the power of 2 multiplied by 7 to the power of 0 over 5 to the power of negative 3, whole to the power of 3 multiplied by 5 to the power of negative 9? (1 point)
Answer:
36/25
Step-by-step explanation:
7 multiplied by 3 multiplied by 2 whole over 7 multiplied by 5, the whole raised to the power of 2 multiplied by 7 to the power of 0 over 5 to the power of negative 3, whole to the power of 3 multiplied by 5 to the power of negative 9
((7 * 3 * 2)/(7 * 5))^2 * (7^0/5^-3)^3 * 5^-9 =
= (42/35)^2 * (1 * 5^3)^3 * 5^-9
= (6/5)^2 * 5^9* 5^-9
= 36/25 * 5^0
= 36/25

b. Factorize using middle term break 3d2 - 16dc – 12c2
Step-by-step explanation:
Given
3d² - 16dc - 12c²
Using middle term break
= 3d² - (18 - 2 )dc - 12c²
= 3d² - 18dc - 2dc - 12c²
= 3d( d - 6c) - 2c( d - 6c)
= ( d - 6c) ( 3d - 2c)
Hope it helps and have a great day onwards ❤
Answer:
= 3d² - (18 - 2 )dc - 12c²
= 3d² - 18dc - 2dc - 12c²
= 3d( d - 6c) - 2c( d - 6c)
= ( d - 6c) ( 3d - 2c)

8+3m= -7
3m= -7-8
3m= -15
How to verify this answer
Answer:
see below
Step-by-step explanation:
8+3m= -7
Subtract 8 from each side
3m+8-8= -7-8
Combine like terms
3m= -15
Divide each side by 3
3m/3 = -15/3
m = -5
Check
8+3m= -7
8+3(-5) = -7
8-15 = -7
-7 = -7
m = -5 is the solution
Step-by-step explanation:
8+3m=-7
3m= -7-8
3m=-15
m= -5

Answer:
These are similar triangles.
By changing the length of the base of the corresponding triangle, the 3 interior angles of this triangle remain equal to the original
Therefore, if these triangles are similar, their corresponding sides must give equal ratios to each other:
This means that BF/FE = BC/CD=FC/ED
The total length of line segment BD=BC+CD; BC=6, CD=42; BD=6+42, BD=48
BE=BF+FE; BE=9+?
if BF/FE=BC/CD then 9/BE=6/42; 6/42=3/21 or 1/7. 9/BE=1/7; 1/7=9/BE
1x9=9, 7x9=63
63=BE
Step-by-step explanation:
Answer:BE is equal to 72.
Step-by-step explanation: They are similar triangles. We know CD and BC. So we can find the comparison between the two. And we see that BC x 7 = CD. So the same will be said for BF and FE. We have BF is equal to 9. So 9 x 7 = 63. However, now we need to add the two together in order to get BE. Because BF + FE = BE. So 9 + 63 = 72

On dividing a natural number by 13, the remainder is 3 and on dividing the same number by 21, the remainder
is 11. Ifthe number lies between 500 and 600, then the remainder on dividing the number by 19 is
9514 1404 393
Answer:
4
Step-by-step explanation:
The least common multiple of 13 and 21 is 274, so the number of interest will be 10 less than that. The value in the given range is ...
2(274) -10 = 536
We are interested in the remainder from 536/19, which is 4.

5.1 is 102% of what number?
Answer:
it is 5
Step-by-step explanation:
102% x 5 =5.1
if you times each answer with you percentage you get the answer
Using the principle of percentage approximation, the value of the number, n is 5
Let the number = n
We then write the expression thus :
(102/100) × n = 5.1
1.02n = 5.1
n = 5.1 / 1.02
n = 5
Therefore, the number, n in which 102% gives a value of 5.1 is 5

A contractor purchases 5 dozen pairs of padded work gloves for $67.20. She incorrectly calculates the unit price as $13.44 per pair for the expense report. What is the correct unit price? What is the error?
Answer:
13.44
Step-by-step explanation:
she is right...........
Answer:
The correct unit price is $1.12 per pair. The error comes from dividing $67.20 by only 5 pairs (instead of 60 pairs).
Step-by-step explanation:
The contractor should have calculated the unit price as $67.20 divided by 60 pairs. Five dozen pairs is 5x12=60. This results in $67.20/60=$1.12 per pair. The error comes from dividing $67.20 by only 5 pairs (instead of 60 pairs).
A rectangle and an equilateral triangle have the same perimeter. The perimeter of the rectangle is 6 ( 1 2 x + 5 ) inches. The perimeter of the triangle is 4 ( x − 2 ) inches. What is the perimeter of each figure?
Answer:
-328/34
Step-by-step explanation:
Here,
Perimeter of rectangle = 6(12x+5)
Perimeter of equilateral triangle = 4(x-2)
Since they are equal, 6(12x+5) = 4(x-2)
or, 72x + 30 = 4x - 8
or, 68x = -38
or, x= -38/68 or -19/34
Now,
Area of triangle ( or rectangle whichever you prefer)
= 4* -19/34 - 8
= -76/34 - 8
= - 328/34
