Equation : 9 + x = 16

9 - 9 + x = 16 - 9
X = 7

It would be 9 + x =16
To solve it, subtract 9 from both sides of the equal sign
So (9+x)-9=16-9
Which is x=7, so the answer is 7.

On a 28 question test how many do i have to answer correctly to get a 70%

balu736 [363]

The closest number of questions you can get right to get a 70% on our test is 20. Because to find a percentage you divide the number of questions to the number of questions you got right. If you get 20 correct out of 28 you got a 71%.

Hope this helps,

Multiply.

makkiz [27]

- $\frac{1}{9}$

multiply the numerators and multiply the denominators

- $\frac{2}{3}$ × $\frac{1}{6}$

= $\frac{-2(1)}{3(6)}$ = - $\frac{2}{18}$ = - $\frac{1}{9}$

How do I do constructions

gladu [14]

Answer:

it depends

Step-by-step explanation:

The required tools are a compass and straightedge. A pencil or other drawing tool will also be useful (or you can use the marker in the compass).

Generally, follow the applicable directions. The specific directions vary, depending on the construction you want to do. Numerous web sites and videos can show you step-by-step. (Search for "construction of ...") for whatever you're trying to construct.

To construct a circle (or part of a circle), set the compass to the appropriate width, place the pointed end on the center of the circle, and rotate the marker in a circle around that point, taking care to ...

keep the pointed end in the same spot,
keep the width of the compass the same until your circle is complete.

To construct a line through two points, align the edge of the straightedge with the two points, and make a mark along that edge using your marking tool. (You may find that you need to make a slight adjustment in your alignment to account for the width of the marker).

All other constructions use combinations of these skills.
