Answer:
b) change the places of the numbers in the numerator and the denominator for the second fraction
Step-by-step explanation:
In the phrase "keep change flip":
You "keep" the first fraction.
"Change" the division sign into a multiplication sign.
"Flip" (or switch) the places of the numerator and denominator in the second fraction.
Example:
[tex]\frac{1}{2}[/tex] ÷ [tex]\frac{1}{3}[/tex]
[tex]\frac{1}{2}*\frac{3}{1}=\frac{3}{2}=1.5[/tex]

Answer:
x =11
Step-by-step explanation:
XWY + YXZ = XWZ
5x+5 + 2x+8 = 90
Combine like terms
7x+ 13 = 90
Subtract 13 from each side
7x= 90-13
7x = 77
Divide by 7
7x/7 = 77/7
x = 11
Keiko runs 6 miles in 55 minutes. At the same rate, how many miles would she run in 44 minutes?
Answer:

What is the equation of the line in slope-intercept form?
Answer: y= 1/4 x + 500
Step-by-step explanation:
The slope is the difference in y-values divided by difference in x-values plus the starting constant value (500 on the graph)
700 - 600 is the difference in y-values = 100
800 - 400 is the difference in x-values = 400
100/400 = 1/4
y = x/4 +500
plz help with my 8th grade mathy math
Answer:
N = 250
Step-by-step explanation:
-17 + [tex]\frac{n}{5}[/tex] = 33
+17 +17
[tex]\frac{n}{5}[/tex] = 50
50 x 5 = 250
n = 250
Answer:
n=250

n/5=33+17
n=50*5 =250
Check;put n=250,
-17+250/5
= -17+50
=33

Which expression uses the associative property to make it
easier to evaluate 6(1/3•7/5)
O A. (6.1/3)7/5
O B. (6•5/7)1/3
O C. 6(7/5•1/3)
OD 3(1/6•7/5)
Answer:
A
Step-by-step explanation:
Here, we want to select which of the expressions correctly use the associative property
The associative property deals with rearrangement
So for (a + b) + c
we can have (a + c) + b
In the case of this question, the associate property is the one that makes the evaluation easier
Thus;
we need to bring 1/3 and 6 together since 3 is a factor of 6
We have;
(6•1/3)7/5

Sonya made a resolution to walk 2.5 kilometers a day. On Tuesday she walked 4 times around the running track at the local high school (each lap is 0.4 kilometers.) How many additional kilometers does Sonya need to walk? (HINT: this is a multi-step problem with 2 operations...)
Answer:
0.9km
Step-by-step explanation:
Given that:
Sonya's resolution = walk 2.5 km daily
Total distance walked on Tuesday = 4 times around a running track
1 lap = 0.4 km
Hence, total distance by walking 4 times around track :
0.4km * 4 = 1.6km
Additional kilometers Sonya needs to walk:
2.5 - 1.6 = 0.9 km

Im trying to plot a slope function on a graph
Answer:
Graphing from slope
Step-by-step explanation:
To graph a linear equation in slope-intercept form, we can use the information given by that form. For example, y=2x+3 tells us that the slope of the line is 2 and the y-intercept is at (0,3). This gives us one point the line goes through, and the direction we should continue from that point to draw the entire line.
