Answer:
there are 12 dogs.
Step-by-step explanation:
d= dogs now plug in the 4 into your equation.
c= cats d=3(4)
d+c=16 d=12
3c+c=16
4c=16 SO THEREFORE THERE ARE 12 DOGS :)
c=4
The calculate the area of a square multiply the base times the height.
Answer:
It will take them 2 hours and 55 minutes to remove the shingles if they work together.
Step-by-step explanation:
The together rate is the sum of each separate rate.
In this problem:
Jackson's rate is 1/7
Martin's rate is 1/5.
The together rate is 1/x, which is what we want to find.
So
So 2 hours plus 0.9167 of an hour.
An hour has 60 minutes.
0.9167*60 = 55 minutes
So it will take them 2 hours and 55 minutes to remove the shingles if they work together.
Answer:
Step-by-step explanation:
Slope-intercept form: y = mx + b
Slope formula:
Given points: (-4, 3), (0, 2)
(0, 2) = (x1, y1)
(-4, 3) = (x2, y2)
To write the equation in slope-intercept form, we need to find the slope(m) and the y-intercept(b) of the equation.
First, let's find the slope. To do this, input the given points into the formula used to find slope:
Simplify:
3 - 2 = 1
-4 - 0 = -4
The slope is .
To find the y-intercept, input the slope and one of the given points(in this example I'll use point (0, 2)) into the equation and solve for b:
2 = 0 + b
2 = b
The y-intercept is 2.
Now that we know the slope and the y-intercept, we can write the equation:
Answer:
108
Step-by-step explanation:
multiply 27 x 8
27x8=216
divide 216/2
= 108
