The cost for 4 hours of math tutoring is 186. The cost for 24 hours is 1001. Write a linear equation to find the total cost “C”

Dvinal [7]

so if 4 hours of math is 186, one hour is 46.5, therefore when you write a liner equation, you start with y=46.5x and then multiply 19 by 46.5

The value of the the expression:

Karo-lina-s [1.5K]

Answer:

5000

Step-by-step explanation:

Let's start by evaluating what we are given. 50 times the sum of 64 and 36. Ok, so 50 times which is the way to write x (multiply) and the sum of 64 and 36 is another way to write 64 + 36.

Lets put this together now!

50 x ( 64 + 36 ) = 50 x ( 100 )

= 5000

Is the open sentence 3z=2z+5 true or false when z=5? A. True B. False

inna [77]

Hey there!

If z = 5

we replace "z" with "5"

So, let's test out the problem to see if it is true or false

Problem becomes: $3(5) = 2(5) + 5$

Let's work this out

$3(5) = 15$

Problem becomes: $15 = 2(5) + 5$

$2(5) = 10$

Problem becomes: $15 = 10 + 5$

$10 + 5 = 15$

So, therefore it looks like this statement/ sentence is $True$ !
