Answer:
they both has 7 slides and the presentation had a duration of 28 seconds
Step-by-step explanation:
we have to setup equation that makes them equal to each other if you know what i mean. 2x+16=3x+10
then we just solve for x
2x+16=3x+10
subtract 10 from each side
2x+6=3x
step 2 subtract 2x from each side
x=6
so both of their presentations are 7 slides long
then to find the length of their presentations we just plug in 6 to one of the equations
2(6)+16
2x6=12 12+16=28 so both of their presentations were 28 seconds
The number of cats that you have is; 27 cats
<h3>How to calculate algebra word problems?</h3>
Let the number of cats alice has be x.
Since you have thrice the amount of cats that alice has, then you have 3x cats.
Bob has 7 less cats than you. Thus, bob has; 3x - 7
If they have a total of 56 cats, then;
x + 3x - 7 + 3x = 56
7x - 7 = 56
7x = 56 + 7
7x = 63
x = 63/7
x = 9
Thus, number of cats you have = 3x = 3 * 9 = 27 cats

Step-by-step explanation:
y - 4x = 3
Writing in slope intercept form that is y = mx + c
y = 4x + 3
Hope it will help :)
Answer:
y = -3/7 x + 41/7
Step-by-step explanation:
The Slope (m) is -3/7
y= mx+ b
They y intercept passing through the pt. (-2,5 ) is
5 = -3/7(2) +b
5 = -6/7 +b
b= 41/7
y = mx +b
y = -3/7 x + 41/7
