Start at 4.

So far you have: 4

Now you go 7 units left. Going left means a subtraction. Going 7 units left means subtracting 7.

So far you have: 4 - 7

The result is -3.

The subtraction is:

4 - 7 = -3

oee [108]

So 72 pencils and 24 calculators
so greates number of identical calculators

this means
what is the biggest number that we can divide 72 and 24 by and get a whole number
this is called the GCM or greatest common multipule

to find the GCM, you factor 72 and group the like ones
72=2 times 2 times 2 times 3 times 3
24=2 times 2 times 2 times 3
so the common group is 2 times 2 times 2 times 3 or 24
so the greates number of packs is 24

so pencils
72 divided by 24=72/24=3
3 pencils per pack

24 divided by 24=24/24=1
1 calulator per pack

answer is 3 pencils and 1 calculator per pack

2(4x-1)+3=7<br> i'm little confused on this

Ratling [72]

Answer:

x = $\frac{3}{4}$

Step-by-step explanation:

Since you cannot subtract -1 from 4x, you multiply 2 × 4x = 8x

Now, you have 8x - 1 + 3 = 7

Seperate the 8x from the other numbers

8x = 1 - 3 + 7 ---> 6

8x = 6

Now simplify

x = $\frac{6}{8}$ <----- to reduce, divide the numerator and denominator by 2

Hence,

x = $\frac{3}{4}$
