Casi drove 135 miles in 3 hours. Use a proportion to find how long it would take her to drive 360 miles at the same speed.
galina1969 [7]

Answer:

8 hours

Step-by-step explanation:

We are given that

Casi traveled distance in 3 hours=135 miles

We have to find the time taken by Casi to drive 360 miles at the same speed using proportion .

Let time taken by Casi to drive 360 miles=x

We know that

Speed=\frac{Distance}{time}

Using proportion

\frac{a}{b}=\frac{c}{d}

\frac{135}{3}=\frac{36}{x}

x=\frac{360\times 3}{135}

x=8

Hence, the time taken by Casi to drive 360 miles=8 hours

7d – 4d – 3d – 5 = 6d
vazorg [7]

Answer:

d = -\frac{5}{6}

Step-by-step explanation:

7d – 4d – 3d – 5 = 6d

<em>(7d - 4d = 3d)</em>

3d - 3d -5 = 6d

<em>(3d - 3d = 0)</em>

0 - 5 = 6d

-5 = 6d

-5/6 = 6d/6

d = \frac{-5}{6}

Hope this helps ^-^

Consider the function f(x) = -2x+15 . What is the value of y when x = 3?
VashaNatasha [74]

Answer:

f(3) = 9

Step-by-step explanation:

Step 1: Define

f(x) = -2x + 15

x = 3

Step 2: Substitute and Evaluate

f(3) = -2(3) + 15

f(3) = -6 + 15

f(3) = 9

The number w and 0.8 are additive inverses.
umka2103 [35]

Since, the number w and 0.8 are additive inverses.

A number 'a' is said to have an additive inverse '-a' if "a+ (-a)= 0".

Since, 'w' and '0.8' are additive inverses of each other such that w + 0.8 = 0

Therefore, the value of 'w' should be '-0.8' so that -0.8 + 0.8 = 0.

So, the value of 'w' is =0.8

Now, Refer to the attached image which represents the position of 0.8 , w ( that is -0.8) and the sum of 0.8 and w.

Sum of 0.8 and w = 0.8 + w

= 0.8 +(-0.8)

= 0.
