What is the value of the expression below.4/5+3/5+3.5×5

Solnce55 [7]

Answer:

18.9

Step-by-step explanation:

4/5 + 3/5 + 3.5 * 5

Well using PEMDAS you would need to do 3.5 x 5 which is 17.5

After that you would to 4/5 + 3/5 which is 7/5 also as 1 2/5

Then you would do 7/5 + 17.5 = 18.9

I might be wrong but that is what I got and I hope it helps you :)

If your friend leaves your house at a speed of 8mph and two hours later you follow in your car at 40mph, how long will It be bef

dusya [7]

Answer:

1/2 hour
20 miles

Step-by-step explanation:

Your friend has a head start of (2 h)×(8 mi/h) = 16 mi.

When you leave, you gain on your friend at the rate of 40 mph - 8 mph = 32 mph. So, it will take ...

(16 mi)/(32 mi/h) = 1/2 h

for you to reduce the distance between you to zero.

In that 1/2 hour, you have traveled ...

(1/2 h)×(40 mi/h) = 20 mi

This is the same distance your friend has traveled in 2.5 hours at 8 mi/h.

What's an equation that the passes through (-6,4) and is parallel to y=1/2x+8

deff fn [24]

By definition, if two lines share the same gradient, they are said to be parallel. So, we know for this equation, it must have a gradient of 1/2.

Now, since the point (-6, 4) passes through the line, we know it must satisfy the equation. Since we have a gradient/slope and a point, we can use the point-gradient form:

$y - y_1 = \frac{1}{2}(x - x_1)$ , where $(x_1, y_1)$ represents the points being passed through.

$y - 4 = \frac{1}{2}(x + 6)$
$2y - 8 = x + 6$
$2y = x + 14$
$y = \frac{1}{2}x + 7$
