F -3 1/4 + (+5/8)
B 3 1/4 + (5/8)
D 3 1/4 + (+5/8)
Of u wanted only one answer it's B
The expressions that are equivalent to [tex]3\frac{1}{4} -(-\frac{5}{8} )[/tex] are
[tex]3\frac{1}{4} +(\frac{5}{8} ) \\\\3\frac{1}{4} +(+\frac{5}{8} )[/tex]
for understanding check the calcualtions here
Calculationan expression is the combination of numbers and operators like +, - * or /
If we have any equal sign then it is an equation .
Given expression is :
[tex]3\frac{1}{4} -(-\frac{5}{8} )[/tex]
to find out equivalent expression we remove the parentheisis by multiplying negative inside the parenthesis
Negative times negative becomes positive
first fraction is positive . So it remains the same
Multiply negative inside the parenthesis . Negative times negative is positive
so, the equivalent expressions are
[tex]3\frac{1}{4} +(\frac{5}{8} ) \\\\3\frac{1}{4} +(+\frac{5}{8} )[/tex]

The set of ordered pairs below represents a function.
{(–9, 1), (–5, 2), (0, 7), (1, 3), (6, –10)}
Josiah claims that the ordered pair (6, –10) can be replaced with any ordered pair and the set will still represent a function.
Select all ordered pairs that could be used to show that this claim is incorrect.
(–9, –6)
(1, 12)
(–10, –10)
(4, 7)
(–5, 1)
Given:
The set of ordered pairs below represents a function.
{(–9, 1), (–5, 2), (0, 7), (1, 3), (6, –10)}
Josiah claims that the ordered pair (6, –10) can be replaced with any ordered pair and the set will still represent a function.
To find:
All the ordered pairs that could be used to show that this claim is incorrect.
Solution:
We need to find the ordered pairs that can be replaced with (6,-10) and for which the set is not a function.
A relation is called function if there exist a unique output for each input.
If (-9,-6) is replaces with (6,-10), then the set has two outputs y=1 and y=-6 for x=-9. So, the claim is incorrect.
If (1,12) is replaces with (6,-10), then the set has two outputs y=12 and y=3 for x=1. So, the claim is incorrect.
If (-10,-10) is replaces with (6,-10), then there exist unique output for each input. So, the claim is correct.
If (4,7) is replaces with (6,-10), then there exist unique output for each input. So, the claim is correct.
If (-5,1) is replaces with (6,-10), then the set has two outputs y=1 and y=2 for x=-5. So, the claim is incorrect.
Therefore, the correct options are (a), (b) and (e).
John bought 12 items from the concession stand. He bought cokes and nachos for his friends. Cokes cost $2.50 each and Nachos cost $3.50 each. He spent a total of $37. How many Nachos did he buy?
Answer: He bought 7 nachos.
Step-by-step explanation:
Let x= Number of cokes
y = Number of nachos
As per given , we have
x+y=12 (i)
2.50x+3.50y=37 (ii)
Multiply 2.5 on both sides of (i), we get
2.5x+2.5y= 30 (iii)
Subtract (iii) from (ii), we get
y=7 (iv)
Put value of y from (iv) in (i), we get
x+7=12
⇒ x= 12-7
⇒ x=5
Hence, he bought 5 cokes and 7 nachos.
Andre builds a form for a new cement step in the shape of a rectangular prism. The form he builds is 40 and 1/2 inches long, 10 inches deep, and 8 inches high. How much cement is needed to fill the form?
Answer:
3240 in^3
Step-by-step explanation:
Step one:
given data
The dimension of the form
Length 40 and 1/2 inches long,
Depth 10 inches deep,
The width and 8 inches high
Step two:
The amount of cement is equivalent to the volume of the form
[tex]V=L*W*H\\\\V=40.5*10*8\\\\V=3240 in^3[/tex]
Hence the volume of cement is 3240 in^3

y=11+4x
3x+2y=0
Answer:
x=-2, y=3
Step-by-step explanation:
substitute 11 + 4x into the second equation for y
3x + 2(11+4x) =0
3x +22+8x=0
11x=-22
To solve for y: y=11+4(-2)

Explanation:
Buddy- 6
Hermey-3
____________________________________________________________
It takes Buddy 94 years to be 100 so you would add 94 to both boys ages!
6+94=100 years old!
3+94= 97 years old!
Answer:
He is going to be 50 years old
Step-by-step explanation:
if he was 3 when his brother was 6 then it would mean that when his brother is 100 he should be 50 because that would be half. You can divide it if you want some extra proof :)
a = 6x-11
g= 36
n = 7x - 27
Solve for x
Answer:
6x - 11 + 7x - 27 = 36
6x + 7x = 13x
-11 + (-27) = -38
13x - 38 = 36
-38 - 36 = -74
13x/13 = -74/13
x = -74/13

Mose decides to launch a rocket out of the barn at Schrute farms. The equation below represents the height (in meters), of the rocket getting launched above the ground, t seconds after the rocket is launched. h(t) = -.4 (t - 2)^2 + 5 How high above the ground is the rocket before it is launched?
Height at an instance of time is given by :
h(t) = -4( t - 2 )² + 5 .....1
Differentiating above equation with respect to t .
[tex]\dfrac{dh}{dt}= -4\times ( -2 ) ( t - 2 ) \\\\\dfrac{dh}{dt}= 8(t-2)[/tex]
Now, for maximum , [tex]\dfrac{dh}{dt} = 0[/tex] .
8( t - 2 ) = 0
t = 2
Putting value of t = 2 in given equation, we get :
h( 2 ) = -4( 2 - 2 )² + 5
h( 2 ) = 5 m
Therefore, maximum height rocket can reach is 5 m.

Find the missing coordinate r.
Answer:
7
Step-by-step explanation:
8 units separate -4 and 4
8 divided by 2 (which is the x of slope) is four
Four times 1 (which is y of slope) equals four

In triangle ABC, angle A is 34 degrees, and angle B is 20 degrees. What is the measure of Angle C
A=34
B=180
C=126
D=54
Answer:
c
Step-by-step explanation:
34+20=54
180-54=126
Answer:
the measure of Angle C is 126 degrees
Step-by-step explanation:
all three angles add up to 180.
to find the answer add the measures of Angle A and Angle B together to get 54 degrees, next you subtract 54 degrees from 180 degrees to get 126 degrees

Here's a graph of a linear function. Write the
equation that describes that function.
Express it in slope-intercept form.
Enter the correct answer.
Answer:
y= 3/2x + 1
Step-by-step explanation:
slope intercept form is y=mx+b. the m is the slope and the b is the y intercept. the y intercept is 1, where it crosses the y axis. the slope is 3/2 because from the y intercept which is 1, you go up 3 and over 2 right.
