so 240 boys
hope this helps mark me brainliest if it did
The answer would be C. if u plug in 4 it would be (4+3)=7x2=49 and also (-10+3)=-7,-7x2 is 49 it works for both so the answer would be C.
Answer:
B.
.
Step-by-step explanation:
Let x be the required angle and y be its complement and z be its supplement.
We have been given that the sum the measures of a complement and a supplement of an angle is 200.

We know that complementary angles add up-to 90 degrees, so we can set an equation as:

We know that supplementary angles add up-to 180 degrees, so we can set an equation as:

We will use substitution method to solve our given equation. From equation (2) and (3) we will get,


Substituting these values in equation (1) we will get,

Combine like terms:




Therefore, the measure of the required angle is 70 degrees and option B is the correct choice.
Answer:

Step-by-step explanation:
The product of a binomial and a trinomial is

we have to simplify that

bringing the like terms together we get



hence our expression becomes

What i would do is multiply $7500 by 10. because it asks what his account will be worth in 10 years so just multiply $7500 by 10.
