The answer x = 11 is correct for problem 4. Nice work.
Use this x value to find the answer in problem 5. From problem 4, we're told that Romeo runs at a speed of 5 m/s. If he runs for x = 11 seconds,then he runs a total distance of:
5*x =(5 m/s)*(x meters) = (5 m/s)*(11 seconds) = 5*11 = 55 meters
The answer to problem five is 55 meters
If you put in the substitutions it would be 2*2-(2*2*4)+(3*2)-(-4*2)+(2*4).
Simplified further by multiplying it would be 2*2-8+6--8+8
the negative 8 could be simplified further since the negatives cancel out so you'll have 2*2-8+6+8+8.
Then using the order of operations you would multiply the 2's together first to get 4 so you have 4-8+6+8+8.
After that it's simple addition giving you an answer of -26.
I'm not sure if you're looking for the final answer or just the equation with substitutions but there's both.
The answer is d because if you take a slither off of the left side instead of twelve you have 11 so 11+11+8+8 would equal 38. 38 isnt an option so you take another slither off so now 12 becomes 10. 10 +10+8+8= 36
Answer:
18
Step-by-step explanation:
Let x represent smallest number and y represent second number.
We have been given that the biggest among three numbers is 2.4 larger than the smallest one. So biggest number would be
.
We are also told that 15 times the smallest one is equal to 12 times the second and 10 times the third. We can represent this information in equations as:


Upon solving 2nd equation, we will get:





Therefore, the smallest number is 4.8.
The biggest number would be
.
Upon substituting
in equation (1), we will get:




Therefore, 2nd number would be 6.
Let us find sum of all numbers as:

Therefore, the sum of all 3 numbers would be 18.
Answer:
x=58
Step-by-step explanation:
1) You have to remember all triangles have to equal 180 degrees
2) You have to know that the box on the left-hand corner of the triangle means it's angle measure is 90 degrees
3) After knowing this you can already add 32+90 and get 122 degrees (32+90=122)
4)Now remember step 1; so you subtract 122 from 180 like so (180-122)
5) After doing so you will get the answer of 58 degrees (180-122=58)
6) So now you solution is x=58
