Answer:
[tex] \frac{5(x + 6)}{5} = \frac{50}{5} \\ x + 6 = 10 \\ x = 10 - 6 \\ x = 4[/tex]
Answer:
x=4
Step-by-step explanation:
5(x+6)=50
First expand the brackets:
5 times x equals 5x
5 times 6 equals 30
Form an equation:
5x+30=50
Do inverse operations to "undo" the equation:
50-30=20
5x=20
20÷5=4 (We divide 20 by 5 because when a number is next to a letter, it means times so we do the inverse and divide).
x=4
We can check our answer by substituting in 4:
5(4+6)
Do brackets first:
4+6=10
5(10)
Then as the 5 is next to the bracket on the outside we times everything on the inside by 5:
5 times 10 equals 50
Hope this helps :)

Write an expression for the sequence of operations described below. multiply 3 by t, triple the result, then raise what you have to the 8th power not simplify any part of the expression .
Answer: 43046721(t^8)
Step-by-step explanation:
So first, multiply 3 by t to get 3t. Then, multiply it again by 3 to get 9t. Raise it to the 8th power to get (9^8)(t^8). This gives you 43046721(t^8)

Chris is trimming trees. He can trim 2/3 of a tree in 30 minutes. What is Chris’s rate for trimming trees in trees per hour?
[tex]\\ \rm\Rrightarrow \dfrac{2}{3}\times 2[/tex]
[tex]\\ \rm\Rrightarrow \dfrac{2(2)}{3}[/tex]
[tex]\\ \rm\Rrightarrow \dfrac{4}{3}[/tex]
Answer:
1/1/3 of a tree
Step-by-step explanation:
30 minutes = 2/3 of a tree
Since 1 hour = 60 minutes,
60 minutes = 2/3 × 2
= 4/3
= 1/1/3 of a tree

calculate the area of the given quadrilaterals.
Answer:
dissect the trapezium into a square and triangle. since the triangle is a right angled one the base is 17-7=10cm
the height is found using Pythagorean theorem to be 24cm i.e 26²=x²+10²,x=√(676-100),x=√576,x=24cn
area of trapezium is (1/2)(a+b)h
a is the shorter side and b the longer side
(1/2)*(7+17)24
=288cm²
There are 2 green pens, 3 blue pens, 4 red pens, and 1 black pen in the teachers desk. The teacher selects 2 pens at random, and the pens are not replaced. What is the probability that the teachers will pick 2 red pens in a row?
Answer:
2/15
Step-by-step explanation:
2 green pens, 3 blue pens, 4 red pens, and 1 black pen =10 pens
P(red) = red/total = 4/10 = 2/5
Keep the pen
2 green pens, 3 blue pens, 3 red pens, and 1 black pen =9 pens
P(red) = red/total = 3/9 = 1/3
P(red,red) = 2/5 * 1/3 = 2/15
question 8b , thanks
Answer:
Step-by-step explanation:
[tex]a = \frac{2b+1}{3b-1}[/tex]
b = 2/3
[tex]2b + 1 = 2*\frac{2}{3}+1\\\\=\frac{4}{3}+1\\\\=\frac{4}{3}+\frac{3}{3}\\\\=\frac{7}{3}\\\\3b-1 = 3*\frac{2}{3}-1\\\\=2- 1 = 1\\\\\\[/tex]
[tex]a = \frac{2b+1}{3b-1}\\\\a=\frac{\frac{7}{3}}{1}\\\\=\frac{7}{3}\\\\[/tex]
a = 7/3
b)
[tex]\frac{2b+1}{3b-1}=a\\\\[/tex]
Cross multiply,
2b + 1 = a*(3b - 1)
2b + 1 = a*3b - 3*a
2b + 1 = 3ab- 3a
2b = 3ab - 3a - 1
2b - 3ab = -3a - 1
b(2 - 3a) = -3a - 1
[tex]b =\frac{-3a - 1}{2 - 3a}[/tex]

Are the ratios 1:2 and 13:18 equivalent?
Answer:
No.
Step-by-step explanation:
If I multiplied 2 by 9 to get 18, I would have to do the same to the 1. This would make the ratio 9:18, not 13:18.
Therefore, these two ratios are not equivalent.

19) One number is 9 more than another. Their product is 11 more than five times their sum.
Find the numbers.
Answer:
-7 and 2 or 8 and 17
Step-by-step explanation:
If we let the numbers be [tex]x[/tex] and [tex]x+9[/tex], the equation to solve this problem will be as follows:
[tex]x(x+9)=5(x+x+9)+11[/tex]
Solving the equation for [tex]x[/tex], we get:
[tex]x(x+9)=5(x+x+9)+11[/tex]
[tex]x(x+9)=5(2x+9)+11[/tex] (Combine like terms)
[tex]x^{2} +9x=10x+45+11[/tex] (Use the Distributive Property of Multiplication to multiply expressions)
[tex]x^{2} +9x=10x+56[/tex] (Combine like terms)
[tex]x^{2} -x-56=0[/tex] (Subtract [tex]10x[/tex] and [tex]56[/tex] from both sides of the equation)
[tex]x^{2} -8x+7x-56[/tex] (Split [tex]-x[/tex])
[tex]x(x-8)+7(x-8)=0[/tex] (Factor by taking a common term out)
[tex](x-8)(x+7)=0[/tex] (Factor by taking a common term out)
[tex]x-8=0[/tex] or [tex]x+7=0[/tex] (Use the Zero Product Property)
[tex]x=8[/tex] or [tex]x=-7[/tex]
Therefore, the first number could be either -7 or 8, and the second number could be -7 + 9 = 2 or 8 + 9 = 17, respectively. Hope this helps!

Identify the slope and y-intercept: y = -x + 13 y help mee please
Answer:
slope : -1, y-intercept : 13
Step-by-step explanation:
-x = -1 times x
+13 = 13 = y-intercept
Answer:
This equation is in slope intercept form, y=mx+b, where m is the slope and b is the y intercept.
So, the slope is -1 and the y intercept is 13.

Butter kruse made 522 glaze donuts and 323 chocolate covered donuts. They put the donuts in boxes. Each box holds 12 donuts. How many boxes do they need?
Answer:
71 boxes
Step-by-step explanation:
1. Add 522 (# of glaze donuts) and 323(# of chocolate covered donuts).....845(# of total donuts)
2. Divide 845 by 12(the # of donuts each box could hold)....70.41666(repeating)
3. As you can't have a 0.41666 of a box, you round up 70.4166666 to 71.
71*12=852 70*12=840
Even though 71 boxes is more than enough to hold 845 donuts, there is simply no other choice, as there is no smaller box that holds less than 12 donuts.
a box's volume set is 112 cubic inches. it has an open top. what is the length, width, and height?
hi
it a cube so it's height,length and width are the same.
if volume is 112 so one if this measure is : 112^(1÷3) =4,82
The sum of first three terms of an arithmetic series is 21. If the sum of the first two terms is subtracted from the third term then it would be 9. find the three terms of the series
Answer:
The terms are - 1, 7 and 15.
Step-by-step explanation:
Let the terms be a-d, a and a+d
ATQ, a-d+a+a+d=21, a=7. a+d-(a+(a-d))=9. d=8. The terms are - 1, 7 and 15.

fins the least number which should be added to 4100 to get a perfect square. also find the square root of the perfect square.
plz sent answer fast
Answer:
Step-by-step explanation:
Find the square of 4100 by long division method
As 4100 is not a perfect square, it will have balance.
Now Find 65 * 65 = 4225
4225 - 4100 = 125
125 should be added to 4100 to get a perfect square
4225 = 5 * 5 * 13 * 13
[tex]\sqrt4225}=\sqrt{5*5*13*13}=5*13=65[/tex]
Nearest square of 4100.
4225=(65)^2[tex]\\ \sf\longmapsto 4225-4100[/tex]
[tex]\\ \sf\longmapsto 125[/tex]
125 should be added
