2x+7=3x+3 is a linear equation with on solution
Answer:
56 problems
Step-by-step explanation:
So we already know that the answer is: 56. However, a good help is knowing how to obtain this answer from the data provided.
Tony's quiz had 80 questions
Tony correctly answered 70% of them.
We can always write a percentage amount as a ratio by dividing the amount by 100.
.
This means that for every 100 questions, tony will respond correctly 70.
So, if Toni did a questionnaire of n questions, the amount that will answer correctly is calculated by the following expression:
If then:
The area of a parallelogram is
I am assuming you're asking for the entire parking lot, so you would have to multiply the above area by 916
So the answer is (D)
Answer: the answer is 176 miles apart
Step-by-step explanation: Since they are both driving for 2 hours the speed they are going is doubled and then added together to get 176
Answer:
C. 24
Step-by-step explanation:
by algebra:
let "?" be x
35/30 = 28 / x (multiply both sides by 30)
35 = (28/x) (30) (multiply both sides by x)
35x = (28)(30)
35x = 840 (divide both sides by 35)
x = 840 / 35
x = 24
