Answer:
(7,10)
Step-by-step explanation:
Since both equations are equal to y, we can set them equal
y=x+3
y=2x-4
x+3 = 2x-4
Subtract x from each side
x+3-x =2x-4-x
3 = x-4
Add 4 to each side
3+4 =x-4+4
7 =x
Now we need to find y
y = x+3
y =7+3

Answer:
It is an Observational study. The population of interest is fifth-grade boys and girls in your school district.
Step-by-step explanation:
Consider the provided information.
Observational study is the study in which observer only observe the subjects, and measure variables of interest without allocating treatments to subjects.
Experiment study is the study in which the researchers are applying treatments to experimental units in the research, then the effect of the treatments on the experimental units is observed.
Now consider the provided survey.
Here, students are randomly selected form the population of fifth-grade boys and girls.
The aim of the study is to observe the subjects and no treatment was administered to the students.
Thus. it is an Observational study.
The population of interest is fifth-grade boys and girls in your school district.
The study is to observe who is faster fifth-grade boys or fifth-grade girls at solving Ken-Ken puzzles.

i think this what you would like
Answer:
C
Step-by-step explanation:
Sum of angles on a straight line = 180
I know it’s A, B, and E
For A you divide 24 by 3
For B you divide 56 by 7
And those both give 8
For C you divide 17 by 9 which isn’t 8.
For D I think you’d subtract 13 from 21 which is 8 but then the equation is -x = 8 so to change x i think then it’d be x = -8
so I don’t think D is right but i’m not 100% sure
