Answer:
The answer is 45.
Step-by-step explanation:
60% of a number is 54, find the original number
54 ÷ 60%
= 54 ÷ 60/100
= 54 * 100/60
= 90
50% of 90 is
90 * 50%
= 90 * 50/100
= 90 * 1/2
= 45

7/8 - 1/12 its a math question
Answer:
19/24 = 0.791666667
Step-by-step explanation:
7/8 - 1/12
Least common multiple of 8 and 12 is 24. Convert 7/8 and 1/12 to fractions with denominator 24.
21/24 - 2/24
Since 21/24 and 2/24 have the same denominator, subtract them by subtracting their numerators.
21 - 2 / 24
Subtract 2 from 21 to get 19.
19/24

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
3p + 15
Taking out common factors.
3 (p + 5) ____(1)
And,
7p - 4p + 15
3p + 15
3(p + 5) _____(2)
From (1) and (2),
3(p + 5) and 7p - 4p + 15 are equivalent expression.
Thus,
The equivalent expressions are:
3(p + 5) and 7p - 4p + 15

Answer:
6 curtains can be made
Step-by-step explanation:
so your dividing by a fraction so you want to convert all numbers into fractions
4/1 divided by 2/3
an easier way to divide fractions is to flip the right one over
2/3->3/2
then multiply
4/1 x 3/2 = 12/2 = 6
hope this helps have a blessed day
Answer:
6 curtains
Step-by-step explanation:
to figure out how many curtains she can make, we have to divide 4 by [tex]\frac{2}{3}[/tex].
[tex]\frac{4}{2/3}[/tex]
However, whenever you divide with fractions, you have to multiply by the reciprocal of the fraction.
[tex]\frac{4}{2/3}[/tex] ⇒ [tex]\frac{4}{1}[/tex] × [tex]\frac{3}{2} = \frac{12}{2} =6[/tex]

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of bacteria samples analyze each day = 15
The equation for the number of bacteria analyzes after x days.
B = 15x
Now,
x = 1, B = 15
x = 2, B = 30
x = 3, B = 45
x = 4, B = 60
x = 5, B = 75

What is the value of a?
Answer:
a=22
Step-by-step explanation:
2a+2=46
2a=46-2
2a=44
a=44÷2
a=22
Answer:
a = 22°
Step-by-step explanation:
Since vertical angles are always congruent we know that 46° = 2a + 2°, therefor...
46° = 2a + 2°
2a = 46° - 2°
2a = 44°
a = 44° / 2
a = 22°

Find three consecutive even integers such that four times
the first minus the third is six more than twice the second.
Answer:
simple just follow me and mark it brainliest
Step-by-step explanation:
LET THE THREE CONSECUTIVE EVEN INTEGERS BE
(x+2) ,(x+4) ,(x+6)
then
according to the question
4(x+2) – (x+6) = 2(x+4) + 6
4x + 8 – x – 6= 2x + 8+6
3x +2 = 2x + 14
3x – 2x= 14 –2
x= 12
the numbers are
14
16
18
Answer:
The three numbers are 14, 16, 18.
Step-by-step explanation:
Consecutive even integers differ by 2.
You can let the smallest of the three numbers equal x. Then the other two numbers are x + 2 and x + 4.
Now use x, x + 2,and x + 4 to represent the 3 numbers and follow the directions to write an equation. The equation will have only one variable, x, so you can solve for x.
"four times the first" -----> 4x
"minus the third" -------> -(x + 4)
"is" -----> =
"six more than twice the second" ------> 2(x + 2) + 6
Put all the pieces in boldface together to arrive at your equation.
4x - (x + 4) = 2(x + 2) + 6
Simplify the parentheses on both sides by distributing.
4x - x - 4 = 2x + 4 + 6
Combine like terms on both sides.
3x - 4 = 2x + 10
Subtract 2x from both sides.
x - 4 = 10
Add 4 to both sides.
x = 14
The smallest number is 14.
x + 2 = 14 + 2 = 16
x + 4 = 14 + 4 = 18
Answer: The three numbers are 14, 16, 18.

What are the y-intercept and axis of symmetry of this quadratic function? 5 Select two answers: one for the y-intercept and one for the axis of symmetry
Answer:
y intercept: (0,1)
Axis of symmetry: x=-2
Step-by-step explanation:
The y intercept is where the curve crosses the y axis.
y intercept: (0,1)
The axis of symmetry is the x value where drawing a vertical line has the left side of the curve a mirror image of the right side of the curve.
Axis of symmetry: x=-2
The required y-intercept is (0, 1) and the axis of symmetry is x = -2. Options A and C are correct.
What is the intercept in the equation?In the equation intercept is the value of the linear function where either of the variables is zero.
Here,
From the above definition in the graph locate the value of y when x is zero,
So, in the graph, when x is zero y is 1
There is why the y-intercept of the given function is 1,
Now,
For the axis of symmetry, just draw a line with a vertex that part the function in two equal halves,
So vertex of the given function is (-2, -3), and the line that divides the function in two equal halves is x = -2
Thus, Options A and C are correct.

Use the Distributive Property to solve the equation.
3 = 3/4 ( b - 8 )
Answer:
b = 12
Step-by-step explanation:
First, distribute 3/4 to both terms in the parentheses:
3 = 3/4(b - 8)
3 = 3/4b - 6
Now, solve for b:
9 = 3/4b
12 = b
So, the answer is b = 12
Answer:
12
Step-by-step explanation:
3 = 3/4 x (b-8)
Distribute 3/4 through the parentheses
3 = 3/4 b - 6
Multiply both sides of the equation by 4
12 = 3b - 24
Move the variable to the left - hand side and change its sign
-3b = -24 - 12
Calculate the difference
-3b = -36
Divide both sides of the equation by -3
B = 12
