1.)
Old Number:35
New Number:45
Now, subract the new number(45) from the old number. (35)
45-35 is 10. Now divide the old number (35) by 10.
You'll get 3.5. 3.5%, increase is the answer for #1.
2.) Old: s (students)
New: 36,750
Do 100+5 (Addition because we do not know what the old number is.) 100+5 is 105. Move decimal over twice and you get 1.05. Multiply 36,750 by 1.05.
There were 38,587.5 kids last year.
3.)Since the discount is 15% off, do 100-15=85. Now, move the decimal over from the percent, and that makes that .85. Now multiply 50x.85. You get 42.5, or $42.50. Now the coupon is 10%, So subtract 100-10, giving you 90. Now move the decimal over. .90. Multiply 42.5 (or 42.50) by .90. You get 38.25. You do have enough money.
4.) Subtract 100-15, giving you 85. Move decimal over from percent. .85.
Now you would multiply .85 times k. B should be the answer.
13+m
-------- = 6
4
Let's elim. the fraction by mult. both sides by 4:
13+m = 24
Consolidate the constants on the right side: m = 11
This does not agree with any of the four answer choices. Please ensure that you have copied down the problem accurately.
Answer:
8 miles per hour
Step-by-step explanation:
because you have to divide 56 by 7 which is 8.
To solve, just invert the equation so 27.75+x=30 becomes x=30-27.75=2.25, making your answer $2.25.
