Answer: the test has 10 multiple-choice questions and 15 Word problems questions.
Step-by-step explanation:
Let x represent the number of multiple-choice questions in the test.
Let y represent the number of Word problems questions in the test.
The total number of multiple-choice and Word problems questions in the test is 25. This means that
x + y = 25
The multiple-choice questions are worth three points and Word problems are worth four points. The test is worth a total of 90 points. This means that
3x + 4y = 90 - - - - - - - - - - -1
Substituting x = 25 - y into equation 1, it becomes
3(25 - y) + 4y = 90
75 - 3y + 4y = 90
- 3y + 4y = 90 - 75
y = 15
x = 25 - y = 25 - 15
x = 10
Answer:
5p = 70 - 30
5p = 40
divide both sides by 5.
5/40
p = 8

Answer:
The answer is A
Step-by-step explanation:
Triangle DEF was rotated and dilated so that's why is looks different than triangle ABC, but it maintained the same shape that is presented in ABC and that is why A is the answer.
Answer:
B. The total price depends on the number of crates
Step-by-step explanation:
We can immediately rule out C & A because the two factors in the graph are crates and total price. So both the number of crates and total price will be part of our answer, but pumpkins aren't shown on the graph at all.
This leaves us with B & D. Using common sense we know that the number of crates isn't going to change if the total cost changes but rather the total cost will change depending on how many crates you buy.
I hope that helps u understand & answers ur question! (If u have a question about anything I just said lmk and I'll be glad to tell u what I mean)
Good luck! :)
