Answer:
-28=7(x-7)
First expand the terms on the right side
That is
-28 = 7x - 49
Group like terms
7x = -28 + 49
7x = 21
Divide both sides by 7
7x/7 = 21 /7
x = 3
Hope this helps
Answer:
so x=3
Step-by-step explanation:
-28=7(x-7)
opening the brackets by multiplying
-28=7x-49
adding 49 on both sides
-28+49=7x-49+49
21=7x
dividing 7 on both sides
21/7=7x/7
x=3
i hope this will help you :)
Answer: smaller number is 23, larger number is 35
Step-by-step explanation:
Let the smaller number be y
The larger number will be y+12
The addition of the numbers is 58.
y+(y+12) = 58
y+y+12 = 58
2y+12 = 58
2y= 58-12
2y= 46
y= 46/2
y= 23
The smaller number is 23
Larger number will be 23+12=35
Answer:
the larger number is 35 and the smaller one is 23

Answer:
140 routes
Total Number of roads from allen to dodge through baker and Carlson is 140 routes.
Step-by-step explanation:
Given;
Number of roads from Allen to baker = 5
Number of roads from baker to Carlson = 7
Number of roads from Carlson to dodge = 4
Total Number of routes from allen to dodge through baker and Carlson is;
N = 5×7×4
N = 140 routes
Answer:
140 different routes
Step-by-step explanation:
The first path (Allan to Baker) has 5 different options, so there are 5 possibilities. After that, there are 7 possibilities from Baker to Carlson. Then, there are 4 possibilities from Carlson to Dodge. To find the total number of possibilities, we just need to multiply the number of possibilities of each track, so:
5 * 7 * 4 = 140 possibilities, that is, 140 different routes.
Answer:
y = 3/4 or y = -3/5
Step-by-step explanation:
Solve for y:
(8 y - 6) (10 y + 6) = 0
Hint: | Find the roots of each term in the product separately.
Split into two equations:
8 y - 6 = 0 or 10 y + 6 = 0
Hint: | Look at the first equation: Factor the left hand side.
Factor constant terms from the left hand side:
2 (4 y - 3) = 0 or 10 y + 6 = 0
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides by 2:
4 y - 3 = 0 or 10 y + 6 = 0
Hint: | Isolate terms with y to the left hand side.
Add 3 to both sides:
4 y = 3 or 10 y + 6 = 0
Hint: | Solve for y.
Divide both sides by 4:
y = 3/4 or 10 y + 6 = 0
Hint: | Look at the second equation: Factor the left hand side.
Factor constant terms from the left hand side:
y = 3/4 or 2 (5 y + 3) = 0
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides by 2:
y = 3/4 or 5 y + 3 = 0
Hint: | Isolate terms with y to the left hand side.
Subtract 3 from both sides:
y = 3/4 or 5 y = -3
Hint: | Solve for y.
Divide both sides by 5:
Answer: y = 3/4 or y = -3/5
The perimeter of the triangle ΔADE will be 30 units.
Let the triangle be ABC.
Then the perimeter of the triangle will be
Perimeter = AB + BC + CA
AC and BD are perpendicular bisectors of each other.
The diagram is shown below.
P = AD + DE + EA
P = 13 + 12 + 5
P = 30 units
More about the perimeter of a triangle link is given below.
#SPJ2
THE CORRECT ANSWER IS 30.
AC and BD are perpendicular bisectors of each other.
=> ABCD is rhombus.
AD = 13
AE = √(13^2 - 12^2) = 5
I just need the equation, not the answer
Answer:
area = lengh x width is that enough of the formula? :D
Step-by-step explanation:
I'll give you the rest, just in case :P My brain got tired at the break before spring, here is the rest
400 = (L+30) X w
400 = 10+30 x 10 ( just b/c I can see 40 x 10 would be 400, calculus could also figure this out for us, but... that would be the minimum fencing he needs to buy and this questions isn't asking that, just make it fit on the back of his house, which we are not given, so just make up something, I used 10 b/c it was convenient )
400 = 40 x 10
2 sides are 40 , and one side is 10
so 90' of fence is needed
