Answer:
b= -15
Step-by-step explanation:
First combine like terms 9-16= -7
Left 3b-7= -52
Next add 7 to both sides
Left 3b= -45
Finally divide
So b= -15

y is 20 less than the
product of five and
half of x.
i need to know the rate of change
Answer:
You can put this solution on YOUR website! 5X - 20 = 10 * X 5X - 20 = 10X Subtract 5x from each side-20 = 5X Divide each side by 5-4 = X. Let's make sure it works... 20 less than five times a number (-20-20) is equal to the product of ten and that number (10 * -4)

1) What number comes after 234 base 5. Explain
2)What number comes before 210 base 5. Explain
9514 1404 393
Answer:
1) 240
2) 211
Step-by-step explanation:
The counting sequence in base 5 is similar to that in base 10, except the digits 5 through 9 are not used. The first few counting numbers are ...
1, 2, 3, 4, 10, 11, 12, 13, 14, 20, 21, 22, ...
When 1 is added to 4 in the units place, a carry to the fives place is generated and the units digit is returned to zero.
234₅ +1 = 240₅
210₅ +1 = 211₅

1. Solve for x in the following problem. You MUST show the equation you set up to solve and the associated work to get to the final answer.
Answer:
x = 5
Step-by-step explanation:
if the lines are parallel, the triangles are similar and thus proportional
set up a proportion:
22/8 = (6x+3)/12
8(6x+3) = (22)(12)
48x + 24 = 264
48x = 240
x = 5
The bar diagram represents 12 months in a year. If u slept 33% of the year how many months are spent sleeping? Represent your answer using the bar diagram.
Answer:
Rounded to whole numbers, if he slept for 33% of the year, he slept for a total of 4 months.
Step-by-step explanation:
Given that in a year there are a total of twelve months, if he slept for 33% of the year, to determine how many months are spent sleeping the following calculation must be performed:
12 - (12 x 33/100) = X
12 - (12 x 0.33) = X
12 - 3.96 = X
8.04 = X
12 - 8.04 = 3.96
Thus, rounded to whole numbers, if he slept for 33% of the year, he slept for a total of 4 months.
are these graphs rational or irrational?
Answer:
rational

HELP!!!! HURRY PLEASE
the length of a rectangle is 6 meters more than its width. if the area of the rectangle is 135 square meters, find its dimensions, PLease provide step by step info
Answer:
length 15 width 9
Step-by-step explanation:
Then the length can be represented by the following expression: (x + 6)
Since area is equal to length times width, we can write the following equation for the area:
A = length * width
135 = (w + 6) * w
Now we can solve for w after using the distributive property and factoring:
135 = (w + 6) * w
135 = w^2 + 6w
0 = w^2 + 6w - 135
This factors to:
0 = (w + 15) (w -9)
w = -15 OR w = 9

Answer:
A: 180° B: 360° C: 540°
Step-by-step explanation:
A: The measures of interior angles of a triangle sum to 180°. Since figure ABC is a triangle, the interior angles of figure ABC sum to 180°.
B: We can see the quadrilateral ACDE is a trapezoid. If you can see, the trapezoid can be split into two triangles if you connect points C and E. As U mentioned before, the measures of interior angles of a triangle sum to 180°. Since we know figure ACDE can be split into two triangles we have to do: 180x2 which is 360°.
C: Now that we know the Pentagon ABCDE can be split into 3 triangles(1 from figure ABC and 2 from figure ACDE), we have to multiply 180 by 3 because like I mentioned before, the measures of interior angles of a triangle sum to 180°. So, 180x3=540°.
Answer:
A) 180
B) 360
C) 540
Step-by-step explanation:
A) All interior angles added together in a triangle are 180°.
B) All quadrilaterals' are 360°.
Think of it as drawing a diagonal to split the quadrilateral equally. You have two triangles, so:
180 + 180 = 360°
C) To find the sum of the interior angles of any polygon, use:
180 (n - 2)
Where n = number of sides. In a pentagon, there are 5:
180 (5 - 2)
180 (3)
540°

General Formulas and Concepts:

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtraction Property of EqualityStep-by-step explanation:
Step 1: Define
-8 = 2y - 2
Step 2: Solve for y
[Addition Property of Equality] Add 2 on both sides: -6 = 2y[Division Property of Equality] Divide 2 on both sides: -3 = yRewrite/Rearrange: y = -3Step 3: Check
Plug in y into the original equation to verify it's a solution.
Substitute in y: -8 = 2(-3) - 2Multiply: -8 = -6 - 2Subtract: -8 = -8Here we see that -8 does indeed equal -8.
∴ y = -3 is the solution to the equation.
