Brady rode his bike 70miles in 4 hours. He rode at an average speed of 17 mph for t hours and at an average speed of 22mph for t

sladkih [1.3K]

Answer:

The Distance cover by Brandy rod at slower speed of bike is 61.2 miles .

Step-by-step explanation:

Given as :

The total distance cover by Brady rode with bike = d = 70 miles

The total time taken by Brady rode with bike = 4 hours

The time taken for average speed of 17 mph = t hours

Let The time taken for average speed of 22 mph = (4 - t) hours

Let The distance cover for slower speed = d miles

<u>Now, From formula </u>

Distance = speed × time

So, Total distance cover = distance at slower speed + distance at faster speed

Or, 70 miles = 17 mph × t hours + 22 mph × (4 - t) hours

Or, 70 = 17 t + 22 × 4 - 22 × t

or, 70 = 88 + 17 t - 22 t

or, 22 t - 17 t = 88 - 70

or, 5 t = 18

∴ t = $\dfrac{18}{5}$

i.e t = 3.6 hours

So, The time taken for average speed of 17 mph = t = 3.6 hours

And The time taken for average speed of 22 mph = (4 - 3.6) = 0.4 hour

So, Distance cover at slower speed = slower speed × time at slower speed

i.e d = 17 mph × 3.6 h

Or, d = 61.2 miles

So, Distance cover at slower speed = d = 61.2 miles

Hence, The Distance cover by Brandy rod at slower speed of bike is 61.2 miles . Answer

Is (7, 9) a solution to the inequality y>2x+1?

OLEGan [10]

No and here’s why

you input the number into your inequality

9>2(7)+1

when you simplify that you get

9>15

and 9 is NOT greater than 15 so no it is not a solution to the inequality

Multiply.

Helen [10]

Okay. When it comes to multiplying decimals, you multiply them just like you would do whole numbers. However, solving them by paper, you would add a decimal point into the answer, depending on how many numbers are behind the decimal point in the numbers being multiplied. In this case, the decimal point will go in front of two numbers, because there are two numbers behind the decimal point in -1.2 and 0.4. Know that the answer will be negative, because there is one negative and one positive number.
Multiply both numbers. -1.2 * 0.4 is -0.48. There. The product is -0.48.

4+7a=12+8a<br> with steps pls

Varvara68 [4.7K]

Answer:a=-8

Step-by-step explanation:

4+7a=12+8a

So first you want to have the variables on the same side

4+7a-7a=12+8a-7a

This is how you got the 7a to the right side. Then you subtract 8a-7a So the equation becomes

4=12+a

Now there are two ways of doing this.

1. 4-12=12-12+a

You moved the 12 to the left side so you have the same variable on one side

4-12=-8

So then a=-8

2. 4-4=12-4+a

0=8+a

then you would have to subtract 8 to keep 'a' by itself

-8=8-8+a

simplify it

-8=a

same thing
