Answer:

72 kph

Step-by-step explanation:

The first sentence tells you the speeds are proportional. So, you can write the proportion ...

kph/mph = 120/75 = x/45

Multiplying by 45 gives x:

x = (45)(120/75) = 72

72 kph is 45 mph.

A self-tanning lotion advertises that a 4 -oz bottle will provide seven applications. Jen found a great deal on a 13 -oz bott

Rainbow [258]

Answer:

22.75 applications

Step-by-step explanation:

From the above question, we understand that:

4 -oz bottle = 7 applications

13 -oz bottle = x applications

Cross Multiply

4 -oz bottle × x applications = 13 -oz bottle × 7 applications

x applications = 13 -oz bottle × 7 applications/4 -oz bottle

x applications = 22.75 applications

Therefore, the number of applications of the 13 -oz bottle self-tanner that should Jen expect is 22.75 applications.

X=6 is a solution to the inequality x−5≤ 10 True or False?

vekshin1

Answer:

$\boxed{\sf{FALSE}}$

$\boxed{\sf{x\leq 15}}$

Step-by-step explanation:

Isolate the term of x from one side of the equation.

First, add by 5 from both sides.

$\sf{x-5+5\leq10+5}$

Solve.

Add the numbers from left to right.

$\sf{10+5=15}$

$\Longrightarrow: \boxed{\sf{x\leq 15}}$

Therefore, the solution is x≤15, which is our answer.

I hope this helps you! Let me know if my answer is wrong or not.
