solve equation of
5/2x=25/4
Answers
Answer:
x = 5/2
Step-by-step explanation:
Solve for x:
(5 x)/2 = 25/4
Hint: | Multiply both sides by a constant to simplify the equation.
Multiply both sides of (5 x)/2 = 25/4 by 2/5:
(2×5 x)/(5×2) = 2/5×25/4
Hint: | Express 2/5×5/2 as a single fraction.
2/5×5/2 = (2×5)/(5×2):
(2×5)/(5×2) x = 2/5×25/4
Hint: | Express 2/5×25/4 as a single fraction.
2/5×25/4 = (2×25)/(5×4):
(2×5 x)/(5×2) = (2×25)/(5×4)
Hint: | Cancel common terms in the numerator and denominator of (2×5 x)/(5×2).
(2×5 x)/(5×2) = (5×2)/(5×2)×x = x:
x = (2×25)/(5×4)
Hint: | In (2×25)/(5×4), divide 25 in the numerator by 5 in the denominator.
25/5 = (5×5)/5 = 5:
x = (2×5)/4
Hint: | In (2×5)/4, divide 4 in the denominator by 2 in the numerator.

Select the term that is suggested by the figure. Then state whether the term is an undefined term or a defined term.
The pencil suggests the term...
Line segment
Point
Ray
^(those are the options)
Which is ....
An undefined
A defined
Answers
Answer:
Step-by-step explanation:
A pencil in the picture shows a segment with a definite length.
We may get confused with the difference in a line and segment.
A line is defined by a line of points that extends infinitely.
That means both the ends of a line are not defined.
But a segment is a part of line which has a definite length between two defined ends.
Therefore, unsharpened pencil defines the term line segment which is a defined term.
Answer:
The unsharpened pencil suggests the term line segment, which is a defined term.

g(x) = -6x + 5 and h(x) = -9x - 11, find (gºh)(x).
Answers
Answer:
g(h(x)) = 54x + 71
Step-by-step explanation:
Step 1: Define
g(x) = -6x + 5
h(x) = -9x - 11
Step 2: Find g(h(x))
g(h(x)) = -6(-9x - 11) + 5
g(h(x)) = 54x + 66 + 5
g(h(x)) = 54x + 71

Which of the following equations is equivalent to 7 = 2y + 9? a.) -3 = 2y + 1 b.) 8 = 9y - 1 c.) -2 = y – 1 d.) -4 = 2y + 6
Answers
The equation 7 = 2y + 9 is equivalent to -3 = 2y + 1 and -2 = y – 1 option (a) and (c) are correct.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that equation:
7 = 2y + 9
After simplification:
2y = 7 - 9
2y = -2
y = -1
a.) -3 = 2y + 1
After simplification:
2y = -3 - 1
2y = -4
y = -1
b.) 8 = 9y - 1
After simplification:
9y = 1 + 8
9y = 9
y = 1
c.) -2 = y – 1
After simplification:
y = -2 + 1
y = -1
d.) -4 = 2y + 6
After simplification:
2y = -4 - 6
2y = -10
y = -5
Thus, the equation 7 = 2y + 9 is equivalent to -3 = 2y + 1 and -2 = y – 1 option (a) and (c) are correct.

[tex]\frac{6}{10}[/tex]
Step-by-step explanation:÷
convert 0.7 to a fraction so [tex]\frac{7}{10}[/tex]
and convert the mixed number to a fraction [tex]\frac{7}{6\\}[/tex]
now divide them
[tex]\frac{7}{10}[/tex] ÷ [tex]\frac{7}{6\\}[/tex]
[tex]\frac{7}{10}[/tex] x [tex]\frac{6}{7}[/tex]
so 7 and 7 cancel out so 1 over 10 and 6 over 1 now multiply and you get

. Carlo’s Bakery is having a special where he packages 6 muffins together for a low price and
he packages 20 cookies together for a low price. His baker realized they sold the same amount
of muffins and cookies yesterday due to this great sale. What is the minimum amount of muffins
that were sole yesterday?
Answers
Answer:
60 muffins
Step-by-step explanation:
Muffins = 6 per package
Cookies = 20 per package
His Baker realized they sold the same amount of muffins and cookies yesterday
What is the minimum amount of muffins that were sold yesterday?
To find the minimum amount of muffins sold, find the lowest common multiple of 6 muffins per package and 20 cookies per package
6 muffins per package = 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84
20 cookies per package = 40, 60, 80, 100, 120
The lowest common multiple of of 6 muffins per package and 20 cookies per package is 60.
Therefore, the minimum amount of muffins sold yesterday was 60 muffins.
solve the following system by elimination x - 4y= 2 and 4x - 16y = 8
Answers
Answer:
0=0
or as separate equations:
y=1/2
X=4y+2
Explanation:
If we solve your system by elimination:
x−4y=2;4x−16y=8 -->
Multiply the first equation by -4,and multiply the second equation by 1.
−4(x−4y=2)
1(4x−16y=8)
Becomes:
−4x+16y=−8
4x−16y=8
Add these equations to eliminate x:
