4x-8=80/2
or, 4x-8=40
or, 4x=48
or, x=12
Answer:
126.
Step-by-step explanation:
Each rectangle is a step. We'll start with the top one. This is simple: 6 times 3.
The farthest left is 5 times 3.
The crossed one is 6 times 5.
The one to the right of the crossed one is 3 times 5, again.
The farthest right is 6 times 5, again.
The bottom one is 6 times 3, again.
Now, we add.
No it is not an equivalent ratio
D,
You basically see if statements are correct or not. Remember this is sample, sample is portion of population so if everything is dome correctly, the results of sample will also display the results of population +- error (standard deviation). So you can just use the sample results to answer questions about the population.
A is correct because social studies has 4 students and reading has 8. Math has twice.
B is correct because reading has 2 and math has 8. Reading is one fourth of math 8*1/4 = 8/4=2.
D is NOT correct because math is 8, social studies is 4. Math is not half of social studies. Social studies is half of math.
Answer:
x = 2
Step-by-step explanation:
First, distribute 6 to all terms within the parenthesis.
6(2x + 3) = 12x + 18
Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
12x + 18 = 42
First, subtract 18 from both sides.
12x + 18 (-18) = 42 (-18)
12x = 24
Isolate the variable x. Divide 12 from both sides.
(12x)/12 = (24)/12
x = 24/12
x = 2
2 is your answer for x.
