Yes, you can use addition to solve multiplication problems!

Here are some examples:

-Let's use 5 x 2 for example. 5 x 2= 10 can be solved as 5 + 5 = 10 since you are technically adding 5 twice.
-Another example would be 3 times 5. 3 x 5 = 15 can be solved by 3 + 3 + 3 +3 + 3 = 15 which is adding 3 five times.
-10 times 10 = 100 : 10 + 10 + 10 + 10 + 10 + 10+ 10 + 10 + 10 +10 = 100

Hope these examples help! :)

Yes. because she can just add how many times she need to multiply. For example let's say she wants to multiply 7 times 7. You can add 7+7+7+7+7+7+7

The answers should be the last two. Domain is along the x-axis, while range is along the y-axis. The cluster lies from 5-7 in the range, and the outlier, or the one that is not with the rest of the data is at (17, 6). Always move along the x-axis then the y-axis when plotting points. Hope this helps!

4/7 - x = 6/35 what is x? how do I determine the answer?
vivado [14]
4/7 - x = 6/35

You're trying to get x by itself, so you have to subtract 4/7 from both sides.

-x = 6/35 - 4/7

You need both of the fractions to the right of the equal sign to have the same denominator so that we could simplify them, so multiply 5/5 to -4/7.

-4 /7 × 5/5 = -20/35

So, our new equation is :

-x = 6/35 - 20/35

Simplify.

-x = -14/35

Divide both sides by -1.

x = 14/35

Divide by 7.

x = 2/5

~Hope I helped!~

[18 POINTS] FIND 3 ORDERED PAIR THAT SOLVE THE EQUATION: 5x-3y= -7
NikAS [45]
If x=0 then we have -3y=-7 
y=7/3 (0, 7/3) is your first pair
if y=0 then we have 5x=-7
x=-7/5  (-7/5, 0) second pair
now create a graph with these 2 points and any point in the line can be your 3rd pair.
